Miller, deceased Filed Mar. 8, 1965, Ser. No. 437,850 8 Claims. (Cl. 227-48) The present invention generally relates to a machine for assisting in the application of composition roof shingles to the surface of a roof thereby reducing the time necessary in applying roof shingles and also reducing the labor involved.

The present invention has for an object the provision of a machine for supporting a plurality of composition roof shingles, dispensing such shingles, dispensing nails used for holding the shingles in place and incorporating a hammer mechanism therein for driving the nails into their secured position.

In using the machine of the present invention, the first course of composition roof shingles are hand nailed in position along the lower edge of the inclined roof surface in a conventional manner. Thereafter, the machine of the present invention may be placed at either end of the roof with guide wheels thereon engaging the top edge of the first course of shingles. End stops are provided and locked in position for exactly positioning the first shingle of each course of shingles thus allowing the operator to move the machine right or left and holding the shingle in its correct nailing position. The machine will dispense the shingles in substantially their position to be nailed with final positioning being a hand operation after which the nail driving mechanism is operated along with the nail dispensing mechanism for nailing the shingle in proper position.

Another object of the present invention is to provide a novel mechanism for retaining a plurality of nails in a magazine and dispensing the nails in a desired relationship to a shingle to be nailed.

A further object of the present invention is to provide a machine in accordance with the preceding objects including a nail driving mechanism in the form of hammer structures that are manually set and released for driving the nails into position for securing the shingles in place.

Yet another object of the present invention is to provide a machine for applying roof shingles to a roof including a structure for supporting a supply of roof shingles and dispensing roof shingles sequentially along each course of shingles with the shingles being dispensed substantially in position for nailing.

Still other objects of the present invention reside in its simplicity of construction, ease of operation, labor saving facilities, and the machine of the present invention is generally inexpensive to manufacture and maintain.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings, forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Referring now specifically to the drawings, the numeral 20 generally designates the roof shingle applying machine of the present invention for use in applying shingles to an inclined roof surface 22. The shingles are designated by numeral 24 and are conventional composition roof shingles with the conventional construction thereof being best illustrated in FIGURES 13 and 14 with the shingles 24 being applied in horizontally arranged courses extending from end to end of the roof. In installing the shingles 24, the first course of shingles are hand nailed in place along the bottom edge portion of the roof 22 in a conventional manner in that the lowermost course of shingles and subsequent courses of shingles are used as a guide for the roof shingle applying machine of the present invention by virtue of the machine having guide mechanisms associated with and engaging certain of the top edges of the courses of shingles.

The machine 20 includes end walls, members or plates 26 and 28 having a configuration as illustrated in FIG- URE 1 and the two end plates 26 and 28 are interconnected rigidly by a rear side frame member 30 and a front frame member 32 secured to the end plates 26 and 28 in any suitable manner. Along the rear longitudinal member 30, there is mounted a pair of supporting brackets 34 and 36 which support tapered wheels 38 and 40 which are journaled thereon and which have an inclined peripheral surface generally conforming with the inclination of the roof 22 for rolling supporting engagement therewith for supporting the rear portion of the machine 20.

Attached to the front frame member 32 is a pair of depending longitudinally spaced brackets 42 and 44 rotatably supporting front support wheels 46 and 48 which are tapered in the same manner as the wheels 38 and 40 generally at the same angle as the inclined roof surface. Also, the brackets 42 and 44 are longer than the brackets 34 and 36 thus supporting the machine in generally a vertical upright manner as illustrated in FIGURES 1 and 6 with the bottom edge of the end plates 26 and 28 being inclined also generally in the same manner as the roof 22 and generally in the same plane as the inclined lower edges of the wheels which support the machine.

Extending between the end members 26 and 28 is a forwardly inclined supporting plate 50 having a plurality of longitudinally spaced hook-like members 52 attached to the lower edge thereof and extending rearwardly and upwardly to form a supporting ledge for a plurality of roof shingles 24 which are orientated in vertical forwardly inclined position with the top edges thereof extending above the top edge of the end plates adjacent the forward edge thereof as illustrated in FIGURES 1 and 6.

Disposed rearwardly of and below the hook-like mem bers 52 is an elongated supporting plate 56 which extends between the end plates or members 26 and 28 and is inclined upwardly and rearwardly for receiving shingles 24 as they are manually deposited from the hook-like projections 52 onto the supporting plate 56. The shingle 24 is illustrated in dotted line in FIGURE 6 and due to the inclined surface thereof the shingle will be discharged downwardly and forwardly in the direction of the arrow for positioning on the roof 22.

Supported on each end member 26 and 28 is a bracket structure 58 and 60 each of which has an angulated upwardly extending end portion 62 for rotatably journaling guide wheels 64 and 66 which are provided with a beveled or tapered peripheral surface having the small diameter orientated towards the forward edge thereof so that the inclined edge of the wheels 64 and 66 will engage the upper edge of a course of shingles 24 in place as illustrated in FIGURES 6, 13 and 14.

Also extending between the end walls 26 and 28 is a bottom longitudinal member 68 which extends through the end members 26 and 28 and has a ledge 69 on the front edge and a grooved guide wheel 70 at one end thereof and a grooved guide wheel 72 at the other end thereof rotatably journaled by a suitable journal bolt 74. A supporting bracket 76 is provided for each projecting end of the member 68 and is engaged with and mounted on the end plates or members 26 and 28 respectively for securely supporting the guide wheels 70 and 72 from the end members 26 and 28.

Also extending longitudinally of the end members 26 and 28 is a front bottom member 78 which has a bottom surface generally paralleling and forming an extension of the bottom edges of the inclined wheels 38, 40, 46 and 48. The ends of the front bottom member 78 are supported by bracket members 80 which are connected to the top surface of the member 78 and extends into overlying engagement with the brackets 58 as illustrated in FIG- URE 1. Also, angular supporting gussets 82 may extend between the front member 78 and the brackets 42 and 44 which support the wheels 46 and 48 respectively thus further rigidifying the front member 78.

At each end of the machine, there is provided a mechanism for locking a shingle in relation to the machine so that the machine may be moved either from right to left or left to right. The mechanism is identical at each end of the machine and includes an elongated rod 84 extending alongside of the end member 26 as illustrated in FIG- URES 1 and 2 in an upwardly and forwardly inclined direction generally paralleling the shingles 24. The rod 84 has a downwardly opening U-shaped yoke 86 at the lower end thereof and is guidingly received through a guide lug 88 having an enlarged aperture 90 therein for enabling longitudinal movement of the rod and also enabling limited lateral movement of the rod generally about the lower end of the yoke 86. The upper end of the rod 84 has a hand grip or handle 92 thereon orientated generally along the top edge of the end member 26 for ease of grasping thereof. Also, the rod 84 has an offset shoulder forming portion 94 above the guide lug 88 and below the hand grip 92 for selective orientation under an abutment member 96. By moving the rod 84 laterally outwardly about a pivot point at the lower end of the yoke 86, the offset shoulder forming portion 94 may be disengaged from the abutment 96 thus enabling the rod 84 to move longitudinally upwardly. By pushing the rod 84 longitudinally downwardly and moving it inwardly towards the end member 26, the shoulder offset portion 94 may be engaged under the abutment 96 and retainedthereunder by the frictional engagement between the abutment 96 and the shoulder forming portion 94 as illustrated in FIGURE 2.

The lower end of the yoke 86 is attached to one end portion of an angulated member 98 by the use of a pivot pin or bolt 100. The central portion of the angulated member 98 is pivotally supported by a pivot bolt 182 extending through supporting lugs provided at each edge of a slot 104 formed in the bottom edge portion of the end member 26 whereby the lower end 106 of the angulated member 98 may swing in an arcuate path towards and away from the surface of the ledge 69 for engagement with shingle 24 to be nailed for moving the shingle to be nailed into abutting engagement with the end of a shingle previously nailed by physically moving the machine. A tension spring 108 is provided between the lower end of the rod 84 and a bracket 110 on the end member 26 adjacent the guide lug 88 for normally urging the rod 84 upwardly thus urging the end 106 of the angulated member 98 into engagement with the ledge 69 and the shingle resting thereon.

Each of the end members 26 and 28 includes an upwardly and forwardly inclined supporting member 112 extending upwardly and forwardly from the front corner edge t'hereof as illustrated in FIGURE 1. Interconnecting the ends of the upwardly extending support members 112 is a longitudinal member 114 and interconnecting the lower ends of the support members 112 is a lower support member 116 thus forming a rigid support for a plurality of hammer mechanisms and nail storing and dispensing mechanisms. There are four nail storage arrangements 118 as illustrated in FIGURE 5 and each of these arrangements include a generally upwardly and forwardly inclined channel-shaped magazine 120 having inturned forward flanges 122 defining a longitudinal slot 124 receiving the shanks of the nails 126 with the heads of the nails being retained by the inturned flanges 122 to retain the nails in a vertical stack as illustrated in FIGURE 10. At the upper and lower end of each channel-shaped magazine 120 laterally extending lugs 128 are provided for securing the magazine to the upper and lower support members 114 and 116. The upper end of the magazine includes a laterally extending lug 130 which extends partly over the upper member 114 for engagement by a loading magazine 132 illustrated in FIGURE 10. At the lower end of the magazine 120, the magazine is curved rearwardly and the side walls thereof are omitted as at 134 thus forming a top plate 136 and a slotted bottom plate 138 having a discharge slot 140 therein which is a continuation of the slot 124 as illustrated in FIGURE 3 and this end of the magazine 1220 terminates under the forward edge portion of the lower support member 116 as seen in FIGURE 10.

For controlling dispensing of the nails to the lower end of the magazine 120, there is provided a plurality of arcuately curved trigger fingers 142 orientated in the path of movement of the shingles as they slide off of the inclined supporting member 56. The arcuately curved fingers 142 are rigidly fixed to an elongated rod 144 that is longitudinally disposed and journaled in lugs 146 formed on a bracket 148 supported from the longitudinal frame member 32. The rod 144 is provided with a plurality of laterally extending members 150 engaging the hook end of a connecting rod 152 in which the hook end of the rod is engaged over the laterally extending end 150. The hook rod 152 has its other end pivotally connected to a laterally extending arm 154 of a generally rectangular dispensing mechanism which includes a pair of arms 156 extending along opposite sides of the magazine 1129 and a vertical bar or plate 158 integral with the arms 156 and having a depending ear 16ft pivotally attached to the rear wall of the magazine 1219 by a pivot bolt 162 whereby the assembly formed by the arms 156 and plate 158 may pivot about the axis of the bolt 162 for rocking m'ovement in the manner illustrated in FIGURE 12.

The two arms 1% terminate in inwardly extending aligned and opposed arms 164 which terminate in inclined ends 166 thus forming an inclined slot generally in alignment with the slot 124 in the magazine 1219. FIGURE 7 illustrates the orientation of the arms 164 and the inclined ends 166 wherein they normally are orientated in blocking relation to the nail as observed from below and when the discharge assembly is pivoted such as when the trigger 142 is moved downwardly as illustrated in FIGURE 3, the slot formed by the inclined edges 166 will momentarily be aligned with the slot 124 for discharging a single nail from each magazine 120. Two of the magazines work in conjunction with each other and the rod 144 has an offset portion 151) at each end thereof and a single trigger 142 at the center thereof as illustrated in FIGURE 7. This structure operates to dispense two nails in response to each time a trigger finger 142 is actuated by a shingle.

- Associated with each of the magazines is a hammer assembly 168 each of which is in the form of an elongated rod 170 having a notch 172 in the lower end portion thereof together with an enlarged head 174 on the lower end which has a substantially flat un-dersurface and is hollow and provided with a magnetic insert 176 secured in place by a setscrew 178. The magnetized insert 176 terminates flush with the lower surface of the head 174 for forming a relatively enlarged striking surface for the nails 126. The rod 176) is slidable within a tubular sleeve 180 which extends to the upper sur face of the lower support member 116 and extends up through an aperture 182 in the upper support member 114 as illustrated in FIGURE with the upper end of the sleeve 18f) terminating in a head 184 resting against the top surface of the top supporting member 114. The sleeve or guide tube 180 is provided with diametrically opposed elongated longitudinal slots 1236 which receives a pin-like fastener 133 which extends therethrough and which extends through the upper end of the rod 1711 as illustrated in FIGURE 10 thus guiding the movement of the rod 17% in the tube and preventing rotation of the rod 171) about its longitudinal axis during reciprocation of the rod 171 in the guide tube 181).

The fastening pin, bolt, rivet or the like 188 also extends through a slide 190 in the form of a sleeve which encircles the guide tube 1% and which is inserted, at least partially, within the upper end of a coil compression spring 192. The sleeve 1% is provided with projecting lugs or pins 194 for engagement with the upper end of the spring and the pin-type fastener 188 is insertable into a selective aperture 1% in the rod 170 to vary the initial compression of the spring 192.

Extending between the adjacent hammer assemblies 116 is an elongated actuating plate 198 having an elongated handle forming rod 2% attached thereto and ex tending upwardly through a guide opening 2112 in the upper support member 114. The upper end of the rod 260 is provided with a transverse handle member 2194 for enabling the actuating plate 198 to be moved upwardly. For guiding movement of the actuator plate 1%, a pair of guide rods 2% are provided which extend through the plate 198 and up through the upper support member 114- and terminate in offset ends above the lower support member 116. Abutments 2518 in the form of sleeves are adjustably attached to the rods 2% and small cushion springs 21% are mounted on the rods 2% under d the abutments 2118 for cushioning upward movement of the plate 1%.

The outer ends of the plate 193 have a projecting lug 212 thereon that is bifurcated by the provision of a notch 214. The end of the spring 192 has a laterally extending end portion 21% which extends under and up into a socket in the bottom of the actuating member 198 so that as the actuating member 193 is forced downwardly the spring 192 will be tensioned when the rod 179 is retained in an elevated or retracted position. A latching means is provided for the rod 171 and includes a generally L- shaped latch actuating member 218 that is pivotally supported in a slot-like opening 22% in the lower supporting member 116 by a pivot pin 222 which supports the L- shaped member 21% adjacent the outer end of the arm thereof pivoted to the lower support member 116. The apex of the L-shaped member 216 is engaged with a flat leaf spring structure 224- that has the center thereof secured to the lower support member 116 and the upwardly extending arm 226 of the L-shaped member 218 is arcuately curved and terminates in an inclined upper end 228 for engagement by the lower surface of the actuating plate 1% when the actuating plate 198 is forced downwardly to its lowermost position. A latching ele ment 23d is pivoted in the slot 226 by a pivot pm 232 and the latching element has a projecting lug 234- which is engageable in the notch 172 in the rod 170. The latch element 231) is provided with an abutment surface 236 in opposed relation to the lug 234 which is engaged by the end of the L-shaped member 218 when the lower edge of the latching element 2% is in alignment with the lower' edge of the lower arm of the L-shaped member 218 as illustrated in FEGURE 8. The spring 224 Will maintain these components in this condition until such time as the actuating plate 198 engages the end 228 of the upwardly curved arm 226 of the L-shaped member 218 at which point the L-shaped member 218 will be pivoted to the position illustrated in FIGURE 9 thus releasing rod 171 When the actuating plate 193 is again elevated, the condition illustrated in FIGURE 8 will again exist. Thus, with the spring tensioned by downward movement of the actuating plate 193, the release of the latching lug 234' will release the hammer mechanism to enable the head to lower and drive a nail under the impetus of the tensioned spring.

Attached to the actuating plate 198, an eye member 233 is engaged by one end of a flexible rope or cable member 2411} that extends downwardly over a guide pulley 242 carried by a U-shaped bracket 24-4- on the edge of the lower supporting member 116 which then extends forwardly and is centrally secured to an offset arm 246 on an elongated rod 248 supported pivotally by brackets 2511 on the lower surface of the supporting member 116. The ends of the rod 243 are laterally offset as at 252 and have tension springs 254 attached thereto. The other ends of the tension spring are connected to offset ends 256 on rods 258 which support an L-shaped plate 260 therefrom between the lugs of a mounting bracket 262 which is actually a rectangular member having a tension spring 264 connected to the outer wall thereof and also connected to the L-shaped member as at 266 adjacent the apex thereof. The L-shaped member 261) is provided with a lower leg 26:8 that is slotted as at 271) to register with and align with the slot in the lower plate 138 as illustrated in FIGURE 3. Thus, each time the actuatingplate 1% is lowered, the hammer head 174 will be released after the spring has been tensioned and also the lower leg 268 will be actuated to withdraw from engagement with the nail so that the nail may be driven completely downwardly to the desired position with the slots 141) and 27% serving to retain the nail in position until such time as the hammer is released with the releasing operation of the hammer head occurring substantially simultaneously with the withdrawal of the leg forming the slot 270.

FIGURE 13 illustrates the first step in operation of the invention in which the first course of shingles has been hand nailed and the second row of shingles has been started with the guide wheels 64 and 66 engaging the top edge of the first course of shingles 24. FIG- URE 14 illustrates the second step in which the wheel 64 is operative but the wheel 66 is not operative and not being used inasmuch as it is rolling on top of the surface of the last shingle nailed. The guide wheel 70 illustrated in FIGURE 14 is not in use while the guiding wheel 72 is in use in that it engages the upper edge of the shingle 24 just nailed. Of course, if the machine is operating in the reverse direction, then the opposite supporting and guide wheels will be in use. The guide wheels 70 and 72 are spool type wheels having a central groove aligned with the top surface of the supporting ledge 69 rigid with support member 68 for receiving the back edge of a shingle resting thereon as illustrated in FIGURE 6. Also, the shingle 24 when approaching support wheels 46 and 48 will engage the pendulum type guards 47 mounted by pivot bolts 49 in front of the wheels to prevent frictional engagement therewith.

In operation, after the machine has been positioned and the shingle manually dropped and properly positioned in abutting aligned engagement with the adjacent shingle, the handles 204 are depressed and all the operations are automatic in that the nails will be automatically driven into position. The handles 204 are then merely pulled upwardly to reset the hammers by virtue of the connection between the lower ends of the rods 206 being connected to the upper end of the latch actuator 218 and the end of the actuating plate 198 being connected with the lower end of the spring which will cause the rod 170 to move upwardly when the actuating plate 198 is moved upwardly. Adjustment of the abutment 208 will be such as to orientate the point of operation of the actuating member 218 when the notch 172 is aligned with the lug 234.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
