ALONZO E. STINEHOUR, OF CAMBRIDGE, MASSACHUSETTS, ASSIGNOR OF ONE-HALF-TO JOSEPH A. WOLCOTT, OF SAME PLACE.

. MACHINE FOR APPLYING BOTTOMS TO PASTEBOARD BOXES.

SPECIFICATION forming part of Letters Patent No. 672,020, dated April 16', 1901.

7 Application filed January 9, 1901. Serial No. 42,646. (No model.)

To all whom it may concern;

- Be it known that I, ALONZO E. STINEHOUR, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Applying Supplementary Bottoms to Pasteboard Boxes, of which'the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to machines for applying supplementary bottoms to pasteboard boxes; and it consists in'certain novel features of construction, arrangement, and combination of parts,which willbe readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which my invention is clearly pointed out.

Figure 1 of the drawings is a front eleva tion of a machine embodying my invention. Fig. 2 is an elevation of the left side of the machine. Fig. 3 is a sectional plan of the same, the cutting-plane being on line 'A Aon Fig. 1. Fig. 4 is a plan of the cross-head and the parts carried thereby. Fig. 5. is a partial elevation of the right side of the machine, the cross-head and the parts carried thereby being broken away. Fig. 6 is a partial sectional elevation of the upper portion of the machine, the cutting-plane being on line B B on Fig. 4. Fig. 7 is a section on line C C on Fig. 6 with the paste-tank'and pasting-die removed. Fig. 8 is4a plan of one of the bot-- tom-supporting plates 31, drawn to an enlarged scale. Fig. 9 is a transverse section on line D D on Fig. 8. Fig. 10 is aplan of the paste-applying die. Fig. 11 is a transverse section of the same on line E E on Fig. 10. Figs. 12 and 13 are respectively a plan and a transverse section of a pasteboard box with the supplementary bottom secured thereto. Fig. 14 is a planof the supplementary bottom, showing in dotted shading the outline of the paste applied thereto to secure it to the box proper. Fig. 15 is a longitudinal section of a portion of the front end of the feed-plate, drawn to an enlarged scale.

Many paper or pasteboard boxes are made with bottoms that project beyond the outer vertical surfaces of the walls of said boxes, which are ordinarily produced by securing supplementary bottoms in the form of rectangular pieces of pasteboard to the bottoms of ordinary paper or pasteboard boxes, said supplementary bottoms having lengths and breadths somewhat greater than the lengths and breadths of said boxes.

The object of my invention is to facilitate the applying of said supplementary bottoms to said boxes, and to this end I have constructed the machine illustrated in the ac companying drawings, in which 1 1 represent the two side frames of the machine, connected together by the bed plate 2 and the tie-rods 3 and 4, as shown. The frames 1 1 are each provided with the inwardly-projecting ears 5 and 6, in bearings in which are fitted so as to be freely movable vertically therein the two upright rods 7 7, having firmly secured upon their upper ends the cross-head 8 and on their lower ends the cross-tail 9, said cross-tail being connected to the under side of the bedplate 2 by a pair of toggle-links 10 and 11.

The frames 1 1 are provided with the bear ing-boxes 12 and 13, in which are mounted the driving-shaft 14 and the crank-shaft 15, respectively, as shown. The shaft 14 has mounted on one end thereof, outside of the frame 1, tight and loose pulleys 16 and 17, respectively, and on its other end, just inside of the frame 1, the spur-pinion 18, the teeth of which engage the teeth of the spur gear-wheel19, firmly secured to the crankshaft 15, said shaft 15 having secured upon its opposite end the cam and locking-disk 20, as shown in Figs. 1, 2, and 3. The crank of the shaft 15 has mounted thereon one. end of the connecting-rod 21, the opposite end of which is connected to the toggle-links l0 and 11, as shown in Figs. 2 and 3.

The cross-head 8 has secured thereto, so as to be movable vertically therewith, the angleiron 22, the upright portion of which forms the front wall of a hopper to receive a pile of bottoms, and also has secured thereto the front ends of two rearwardly-projecting bars 23, the inner edges of which are rabbeted to form guiding-bearings for the feed-plunger 25, as shown in Figs. 1, 2, 6, and 7. The upright plate of the angle-iron 22 has adjustably secured to its rear face the two vertical plates 26, which form the sides of the bottomreceiving hopper and are movable toward and from each other to adapt the width of the hopper to the length of the bottom-blank, they being secured to said angle-iron 22 by means of the bolts 27, which pass through horizontal slots 28, formed in the angle-iron 22, said hopper-plates 26 having formed upon or secured to their front vertical edges the laterally-projecting thin plate-like ears 29, which are fitted to a shallow groove 30, formed in the rear face of the upright portion of the angle-iron 22, so as to maintain said hopperplates 26 in upright positions and permit them to be readily adjusted toward and from each other by simply slackening a single bolt in each, moving said plates, and tightening said bolts again. The lower edges of the hopper-plates 26 have each secured thereto the thin metal plate 31, which project beyond the front edges of said plates 26 to the front edge of the horizontal portion of the angle-iron 22 and have their inner edges rabbeted to a depth equal to the thickness of the rectangular pieces of pasteboard which form the supplementary bottoms to be secured to the boxes, a pile of which are to be placed in said hopper, with their ends supported by the inner rabbeted portions of the plates 31, which project beyond the inner vertical surfaces of said hopper-plates 26, the upper surfaces of the rabbeted portions of the plates 31 being arranged just sufficiently below the under surface of the horizontal portion of the angle-iron 22 to permit the lower blank in the pile in the hopper to be fed forward beneath said angle-iron without disturbing those blanks above the bottom one. The inner vertical faces of the l hopper-plates 26 have adjustably secured thereto the gage-plates 32, the lower ends of which rest upon the projecting lips of the plates 31 and are secured to said plates 26 by the screw-bolts 33, which pass through the horizontal slots 34, formed in said plates 26, as shown in Figs. 2, 4, and 6.

The feed-plunger 25 has secured to its upper side and central of its width the steel feed-blade 35, provided near its front end with the shoulder 36,to engage the lower blank of the pile in the hopper to feed it forward, and with a short forward extension beyond said shoulder, the upper surface of which is inclined to insure its passage beneath said blank without disturbing the same until said shoulder comes in contact therewith. The near end of the plunger 25 is connected by the link 37 to the upper end of a lever 38, made, preferably, in two parts, each pivoted at its lower end upon the shaft 14, and each arm of said lever carries a truck 39, which is engaged by a cam 40 to move said plunger to the rear against the tensions of the springs 41, secured at one end to said lever and at the other end to the bed-plate 2 or to any other suitable fixed portion of the machine, the reaction of which springs serves to move said plunger toward the front and feed a blank from the hopper to a position beneath the cross-head 8 or the angle-iron 22, secured thereto.

The bed-plate 2 has firmly secured to its upper side the standard 42, having fitted to a shallow groove formed in its upper end, so as to be movable toward and from the rear by means of the adjusting-screw 43, the plate 44, having set therein two upwardly-projecting pins 45, which enter holes in the box-holding block 46, which has a length and width to fit the interior of the box to which the supplementary bottom is to be attached, said block 46 being removed and another substituted therefor when a different-sized box is to have the supplementary bottom secured thereto.

A paste-tank 47 is attached to the under sides of the bars 23 by means of the swiveling buttons 48, two in front and two in the rear, which engage outwardly-projecting flanges 49, formed on the front and rear sides of said tank, as shown in Figs. 1, 2, and 6, by which construction and arrangement the paste-tank may be readily removed for cleaning and replaced by simply turning said buttons aboutv their pivotal axes.

The bed-plate 2 has formed in one piece therewith or secured thereto near its left end and at its rear side the arm or bracket 50, in which is set the vertical rod 51, having adjustably secured thereon near its upper end the bar 52, which projects inward over the left end of said paste-tank, then downward, and again inward, as shown in dotted lines in Fig. 1, and has secured to its inner end the paste-applying die 53, as shown in dotted line in Fig. 2 and in full lines in Figs. 6, 10, and 11.

The upper end of each of the rods 7 has fitted thereon, between the end of the crosshead Sand the nut 54, two metal washers 55 and 56, and between said washers a cushion of rubber 57, as shown in Figs. -1, 2, 6, and 7, whereby the cross-head is rendered slightly yielding to compensate for slight variations in the thickness of the pieces of pasteboard which form the supplementary bottoms for the boxes.

On a stud 58, set in the right-hand frame 1, is mounted the treadle-lever 59 and the shipper-lever (30, the front end of the lever 60 being connected to the lever 59 by a suitable clamping-bolt, with a cushion of rubber 61 between them, as shown in Figs. 2 and 3. The rear end of the lever 60 has mounted upon a suitable stud set therein the shippertruck 62, the periphery of which is V-shaped and engages the conical surfaces formed on the contiguous ends of a hub fixed on the shaft 14 and the hub of the loose pulley 17 to force said pulley 17 into frictional contact with the tight pulley 16 in a well-known manner. The treadle-lever 59 extends to the rear from its fulcrum and upward and carries at its rear end the cam-truck 63, which is acted upon by the cam-surface 80, formed in the inner face of the disk 20, to hold said lever in the position with its front end depressed after the operator removes his foot from the treadle"until the proper time, when said cam releases said lever and allows the reaction of the spring 64 to raise the front end of the levers 59 and 60, thereby permitting the loose pulley 17 to be moved'from contact with the tight pulley 16, and the movements of the machine are arrested just when the toggle has assumed the position shown in Fig. 2 and the cross-head, with all the parts carried thereby, has been raised and the block 46 is so relieved from the vertically-movable mechanism that the box thereon may be readily removed and another placed thereon. The lever 59 has secured thereon and movable therewith the upwardly-projecting arm 65, the upper end of which engages the shoulder 66, formed in the periphery of the disk 20, to lock said disk against revolution until the lever 59 is again depressed, when said arm is disengaged from the shoulder 66 and the brakeshoe from the pulley 16. The lever 59 also has secured thereto and movable therewith the laterally and upwardly projecting arm 67, the upper end of which contacts with the periphery of the tight pulley 16 to check the momentum of the driving-shaft when the loose pulley is released from frictional contact with said tightpulley.

Each of the bars 23 has secured to its upper side, just in the rear of and in close proximity to the rear vertical face of the angle-iron 22, the spring-arm 68, which projects inward substantially parallel to said rear face of the angle-iron, but slightly below the lower horizontal face of said angle-iron, and has set therein, near its inner end, the upwardly-projecting pin 69, the upper end of which presses against the under surface of the lower pasteboard blank contained in the hopper to hold it in the proper position to insure its being fed forward when the plunger 25 is moved to the extreme of its forward movement, said springarm being provided with the adj listing-screw 70, by which the level of the upper end of said pin 69 may be varied to suit the conditions of dilferent cases, all as shown in Figs. 1, 4, and 7 In Figs. 12 and 13 is shown the box 71, with the supplementary bottom 72 secured thereto.

The paste-applying die 53 is provided with the raised ribs 73, extending along each side and end, and at each corner with oblique extensions 74, (see Fig. 10,) the upper edges of said ribs and corner extensions forming the paste-applying surface, which comes in contact with the under surface of the lower piece of pasteboard contained in the hopper when the cross-head and the parts carried thereby are moved downward, while the pasting-die remains stationary and leaves an impression in paste thereon, as indicated by the shaded figure 75 in dotted lines on Fig. 14.

The front edge of the horizontal portion of the angle-iron 22 has adjustably secured thereto by suitable binding-sore ws two clamplike stands 76, in each of which is mounted a vertical rod 77, having its lower end bent at right angles to serve as a button and its upper end screw-threaded and provided with the adjustable nut 78 and surrounded between its bearing and said nut by a coiled spring 79, which acts to press said rod upward, the button portion below its bearing being arranged to be turned under the front end of the plate 31 and hold it with a yielding pressure against the under surface of the horizontal portion of the angle-iron 22, as shown in Figs. 1 and 4.

The operation of myinvention is as follows: The several parts of the machine being in the positions shown in Figs. 1, 2, and 3, the pastetank 47 being charged with paste, the hopper with a pile of the supplementary bottoms and a suitable box-receiving block 46 being placed in the proper position on the standard 42, the operator places a box-body 71, without a supplementary bottom, upon said block, as indicated by dotted lines in Fig. 6, then places his foot upon the treadle-lever 59 to depress its front end and the front end of the shipperlever 60, thereby disengaging the locking-arm 65 from the shoulder 66 of the disk 20, the brake-arm .67 from contact with the pulley 16, and causing the shipper-truck 62 to engage the conical end of the hub of the loose pulley 17 to move it into frictional contact with the pulley 16, thereby causing the shaft 14 to be revolved in the direction indicated by the arrows a and the crank-shaft 15 in the direction indicated by the arrows b, both in Figs. 2 and 3. The depression of the front end of the lever 59 causes the truck 63 to be moved obliquely upward into a position to be engaged by the portion of the cam 80'formed in the disk 20, having the smallest radius, which serves to hold said lever in its depressed position after the operator has removed his foot from the treadle until the crank-shaft has made about three-fourths of a revolution and the smaller part of thesaid can] has passed from beneath said truck, when the reaction of the spring 64 returns said treadle-lever 59 to the position shown in the drawings. The shaft 14 continues to revolve after the front ends of levers 59 and 60 have been raised by the action of said spring 64 until the shoulder 66 on the disk 20 comes in contact with the upper end of the locking-arm 65, when the motions of said shafts are arrested. The first effects produced by the movement of the crank-shaft 15 in the direction indicated by the arrow 1) is to move the center of the toggle 10 11 toward the front of the machine, thereby moving the cross-tail, the cross-head 8, and all the parts carried thereby downward, and at the same time by the action of the cams 40 upon the trucks 39, carried by the lever 38, the feed-plunger 25 and feedplate 35 are moved to their extreme rearward positions. When the cross-head has descended to its lowest position, the under surface of 'the angle-iron 22 comes in contact with the box on the block 46 or with the supplementary bottom resting thereon, and if said bottom has been pasted will secure it to said box. In beginning work, however, there would be no supplemetary bottom pasted and in position to be acted upon when said cross-head is depressed the first time; but such depression carries the paste-tank downward, so as to uncover the pasting-die 53, with which the lower piece of pasteboard in the hopper comes in contact and receives an impression of paste, as indicated by the shaded outline on Fig. 14. A continuation of the revolution of the shaft 15 causes the toggle to be broken, and the cross-head and the parts carried thereby are moved to their uppermost positions and during the same time the feed-plunger and plate are moved forward, the shoulder 36 on said plate coming in contact with the edge of the lower pasteboard in the hopper and feeding it forward beneath the angle-iron 22 into a position directly above the box on the block 46, with its ends resting on the narrow rabbeted edge of the plates 31, when the rotation of the shaft 15 is arrested, as above described, and the operator removes the box on the block 46 if a supplementary bottom has been previously secured thereto and places thereon another box 71. He then again depresses the treadle-lever, and the next revolution of the shaft 15 causes a repetition of the movements described, and the previously-pasted supplementary bottom is pressed firmly into contact with the box on the block 46 and is firmly cemented thereto.

What I claim as new, and desire to secure by Letters Patent of the United States, is-
