PAPER PUNCH Filed Aug. 23, 1929 2 Sheets-Sheet 2 INVENTOR Patented May 20, 1930 UNITED STATES PATENT OFFICE JEREMIE TELLIER, OF NEW BEDFORD, MASSACHUSETTS PAPER PUNCH Application filed August 23, 1929. Serial No. 387,974.
This invention relates to improvements in adjustable paper punches,'and one of its leading objects is to provide a device of this character with a pair of independently opcrating punches, mean'sfor adjusting the punches'relative to each other to vary the spacing required between companion holes required in the edge of a sheet of paper or cardboard, and a combined handle bar and distance gauge for operating both punches, so arranged that the exact distance between the punches will-be indicated at a point always in the direct sight of the operator, and yet one of the punches may be operated in dependently of the other, if desired. I
Another obj ect of the invention is the provision of a changeable die'set for each punch, whereby the size of the hole produced may be varied at will. a
A further object of the invention is the provision of a handle lever system whereby powerful pressure may be exerted upon the male punch elements, and yet these may be readily withdrawn and others placed in position. I I
The invention also comprises other objects, combinations, constructions and arrangements of parts, clearly described in the following specification, and fully illustrated in the accompanying drawings, which latter show an embodiment of the invention as at present preferred and in wh1ch:
Fig. 1 is a perspectlve view of my 1mproved adjustable punch. I 35 Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1.
Fig; 3 is a detail perspective view of one of the detachable waste pans.
Fig. 4 is a central vertical sectional view taken on line 4-4 of Fig. 2, showing the mounting of the screw for adjusting the two punchesrelative to each other. 7
Fig. 5 is a detail vertical sectional view through one of thepunches, taken on line 5-5 of Fig. 2. a Fig. 6 is a similar view, showing thebottom female die of the punch set, in eleva tion. I
Fig. 7 is aview of an assembly for the punch, shown in perspective, with the parts separated.
Referring to the accompanying drawings, which illustrate as aforesaid a practical embodiment of my invention, 5 designates the base for the right punch, and 6 the base for the. left punch, The base 5 is formed with apair of parallel holes 5 and 5?, shown to be positioned near the opposite ends of the base. In these holes the ends of the guide rods 7 and 8 are located, and set screws 7 and 8 threaded through the base hold these rods against relative longitudinal movement tosaid base. The opposite end portions of therods slidably extend through the parallel holes 6 and 6 of the left base 6. 7
Midway of the guide rods 7 and 8 an adjusting screw 9 is rotatably mounted in the right base 5 and extends through an internally threaded lug 1O formed'on the left base 6. The right end portion of the adjust ing screw 9 is formed with ashoulder 9*, which bears against the bearing lug 11 formed on the right base 5, while a stop collar 12 is secured to this screw against the oppositeside of the saidbearinglug, to limit the relative longitudinal movement of the screw 9 in the base 5. I a
All three rods are disposed in parallel relation to each other, so that an easy adjustmentof the two bases maybe accomplished by a finger turning of the screw 9, the outer end of which isprovided with a knurled head 9 for this purpose.
The base is equipped with an integral up-c standing post 13, which is provided with a forwardly offset bearing lug 13*,the lower end of whichis slightly spaced above the flat upper surface of the base, to provide the necessary restricted space for the admission of paper or cardboard. The lower end of this bearing lug is formed with an internal shoulder 13, through which the male punch 14 operates; This punch is formed with. an external shoulder 14 An expansion spring 14' is-located around the male punchand bears at its lower end against theshoulder 13 and at its upper end against the shoulder 14. The portion of the shank of the male unchabove the shoulder 1491s cylindrical an i is designed i to have a smooth sliding fit with the eylindrical bore of the bearing lug 13*, while the upper end of this punch is rounded to provide a .smooth engagement with the curved recess wall .15 of the handle bar 15.
The handle bar 15 is pivoted to the upper end of the post 13, the sides, of which are fiat, while the end of the handle bar bifurcated to straddle the post. In this case the pivot consists of a bolt 16 detachably secured to the post by means of the nut 16*; this pivot bolt extending through aligned openings in the bifurcated end of the handle. The V handle abuts against the post18 in its upper position, and is normally held at a slight upward-an le by the pressure of the coil spring 1 a i Themale punch is formed on its lower end with a hardened perforating tool 14; which is designed to enter the female element of the punch set, or die, 17;, In" order to retain the female punch element or die in place against tlie thrusts produced during the operation of puiiching paper'orothjer material, this female member an die is formed with an integral head 17*, which is seated in the nest 17 b termed in th has'e 5, around the waste hole 17 A keeper plate 18 is secured to the base 5 by meanest-the screws 18 which are threaded through the botteih time said baseinto threaded openings 18 provided in said 'kee p plate, Thiske'eper plate is seated ina iistplS formed in the upper side of the base 15*, e6 that the'upper surface of said keeper plate will be in the same plane as the base itself. In this way thrusts developed against the female die are distributed by th e'keeper over a relativelylarge area of the base, while the die is retained against wobbling.
' the die or punch set, the hole produced be varied in size at the will of "the'operator.
' The, left base 6 is equipped'with an integral 19 which is fdrined with a bearing lug 1'9 f, s imil ar to the bearinglug 18 In this hearing lug'tlievmale punch 21-, correspondto' the punch 14 or 14 -1 1, operates against a coil'spring similar to that described with reference to the male punch 14. The
upper end of the post .19 is provided with fiat sides to which thebifurc'atede-nd of the hand'le' bar22is pivotedhy means of the bolt 23, which is detacliably held in place by the nut 23 This handle barbea'rs against the rounded upper endof the male punch 21, and is held at an upw a gl by the coil spring which surrounds the punch 21.
'- The left base 6, a manner notshown,-
ihcorporates elements corresponding to the 17* and 17 so that,'as desired, a part corresponding to die 17 may or may not be employed. On base B'there is a keeper plate 25, heldlin 'p la'1'ce by the screws 25 this plate 25 being, similar.to the plate 18 on basevb,
'rod in selected position.
A combined handle bar and gauge 26 is positively secured to the handle bar 15 by" means of the screws 26, and extends over the handle bar 22, but is not connected or attached thereto, merely bearing against the upper side thereof. The gauge bar 26 is provided with graduations 26, arranged in'any desired order, and the handle bar 22 is equipped with an indicating pin or pointer 26 designed to ride close to the adjacent edge of the gauge'bar. I
Each base'is equipped with its own waste a pan, the base 5 having a waste pan 27 which is held in place for'ready detachment by the 4 screws-0r pins 27*, secured to the base, and provided with'angular arms 27 to engage the pan and hold it in place.
The base 6 is equipped with the waste pan 7 28, held in place for easy removal by the screws or pins 28, which are, likewise,' formed with angular arms 28*. Each base is further equipped with rubber cushion feet 29, so that of the paper or cardboard to the punch; This 7 7 gauge is shown to be in the form of a rod} which slides through an opening formed in the 'post 13, and its outer end isprovided with an angular arm. 30 against which the edge of the sheet abuts, Al'set screw 31 threaded through the postholds the It will be observed that the operator can" quickly determine the spacing ofthe two punches bymerely-p'laci ng a sheet of paper or other material, showing the correct hole V ga I spacing, on the combined handle. and gauge bar, and that any required changein the spec ing of the punches may be quickly accomplished by the mere turning of the adjusting V i Y screw.
The length ofeach of the handle bars 12 and 22 from its bearing on the punch engaged 7 thereby to the extreme formed-end thereof is 1 shown to vbe about four times the distance from the center of thepunch to the pivot of the handle, thus providinga long and powerful leverage. The proportionsshown may be changed at will. The punches are so mounted a that they have a short s oke, thus limiting the stroke required on the combined handle and gauge bar.
The bases are positively maintained in par-- allel relation to each other by the two guide rods and the adjusting screw, and no matter what the distance betweenthe two punches may be pressure upon the combined handle: bar andgauge will operate both unehes si multaneously. As there is no connection between the left punch handle and the common operating handle bar, the left punch may be operated independently of the right punch, should occasion so require.
What I claim as new-is:
1. An adjustable punching device consisting of a pair of punching units, each having an operating handle, an adjustable connection between said units, and a combined handlebar and gauge secured to one of said handles and overlying and adapted to bear upon the other of said handles, said other handle having a pointer to co-operate with said gauge to indicate the spacing between the punching centers of the two punching units.
2. A punching mechanism consisting of a pair of punching units, guide rods secured to one 0 said units and slidably extending through the other unit, a screw mounted for rotation on one of the units and threaded through theother unit, each of the units having a handle to operate the same, and a handle bar connected to one of the handles and overlying and adapted to bear upon the other handle but not connected thereto.
3. In combination, a pair of substantially similar bases, guide rods secured to one of the bases and slidably extending through the other base, means for moving the bases to ward and away from each other, an upstanding post on each of the bases, said post having a bearing lug, a male punch element mounted in each bearing lug, avcoil spring in said lug to exert upward pressure on said punch element, a handle pivoted at its rear end to each post and a combined handle bar and gauge mounted on one of said handles and overlying and adapted to bear upon the other.
4. In combination, a pair of independent bases, means for connecting the bases for parallel sliding motion, means for moving the bases toward each other and away from each other, a punching device mounted on each base, a spring pressed handle for each punching device, and a common handle bar mounted on one of the handles and overlying and adapted to bear upon the other to permit both punching devices to be operated simultaneously or independently.
In testimony whereof I hereby aflix my signature.
