AUGUST LOUDERSI-IAUSEN, OF DAYTON, OREGON.
PUNCHIN G-MACHIN E.
Specification of Letters Patent.
Application filed May 14., 1910.
Patented J an. 17, 1911. Serial No. 561,423.
To all whom it may concern:
Be it known that I, AUeUsT LOUDER- SHAUSEN, a citizen of the United States, residing at Dayton, in the county of Yamhill and State of Oregon, have invented new and useful Improvements in Punching-Machines, of which the following is a specification.
This invention relates to combined leather cutting and punching machines and has for its object the provision of means whereby a plurality of different cutting dies may be alternately secured in position and moved toward the cutting table without involving the use of intricate or expensive mechanism.
A still further object of the invention is the provision of means for automatically throwing the work into cutting position independent of its initial position on the cutting table whereby the dies will properly engage the work and make the cuts or punches in the correct places or positions.
A still further object of the invention is the provision of a novel sliding die holder together with means for operating the same and means for regulating the throw of the die holder whereby different pressures may be obtained for cutting different materials and for insuring a clean passage of the dies through the material to the table.
Further objects of the invention Will appear as the specific description which follows is read in connection with the accompanying drawings which form a part of this specification, and in which:
Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a rear elevation. Fig. 1 is a vertical transverse section taken on the line lt of Fig. 1. Fig. 5 is a detail horizontal section taken on the line 55 of Fig. 1. Fig. 6 is a detail vertical longitudinal section taken on the line 66 of Fig. 5. Fig. 7 is a detail bottom plan view of the die holder. Fig. 8 is a top plan view of one of the dies used. Fig. 9 is a longitudinal section thereof.
Referring more especially to the drawings, the frame of the device consists of four standards or legs 1 which are braced apart by horizontal and diagonal braces 2 and 3 and are preferably constructed of L-irons with their bottoms split along the edge and bent outwardly to form feet 4.
Bridged across the upper portions of the legs 1 are cross braces 5 which support the work table 6 and the rear legs are extended above the table and have secured thereto portions of the die holder and have passing therethrough the set screws 18 which connect and secure in position the dies shown in Figs. 8 and 9. These bridge pieces l5'and 16 form abutments for the dies and the die holder slides on the bearing members or plates 9 between side bars 19 which are adjustable by means of the set screws 20 so that lateral play of the vertical sides ofthe die holder is prevented.
Slidably mounted in the bearing brackets 10 are suitable bearing blocks 21 in which is mounted a shaft22 arranged immediately above the shaft 17 which is journaled in the bridge pieces 14. The bearing blocks 21 are adjustable in the brackets by means of the set screws 23 so that the throw of the die holder may be regulated. On opposite sides of the die holder the shafts 22 and 17 are interconnected by toggle levers 24 which are connected at their intermediate knuckle points to levers 25 by the links 26. The levers 25 are journaled or mounted upon the transverse shaft 27 secured in ears 28 pro jecting upwardly from the rear legs 1 of the frame and the outer ends of the levers have connected thereto the operating rods 29 which extend downwardly and have their lower ends secured to the side arms 30 of the treadle 31 which is normally held in raised position by a spiral spring 32 connected to the cross braces 33 of the treadle and to one of the horizontal braces 2 of the frame. When the treadle 31 is depressed, the rods 29 are thrown downwardly and the links 26 thrown inwardly through the levers 25 to spread the arms of the toggle levers, the lower arm of the toggle levers being connected to the movable die frame and the upper arm of the toggle lever being connected to the stationary shaft causes the die frame to be projected downwardly toward the table. When the treadle is released the spring 32 returns the parts to normal position. The rear arms of the of the treadle 31..
mover and a belt shifting lever 43 is pivoted,
treadle 31 are pivoted to a rearwardly extending portion of cross braces 33 which are connected at their rear ends by a rod 34 and each are braced vertically by legs 35 connected at their lower ends to the rear legs Y 1 by suitable braces 36.. In this manner contothe frame in such a manner that its operation. will shift the belt from one position to the other is desired to start or stopthe machine when it is desired to use power instead of operating the same manually.
Depending from the table supporting bars 5 are suitable shaft brackets 44:- in which; are
journaled the shafts 15. To these shafts are connected the respective arms of a toggle lever 46 having its centrally connected ends slotted as at 47 so as to permit the pivotal bolt 48 to engage the same and operatein the slots without drawing the shafts 45 together. The pivotal bolt t8- is connected tothe side bars 30- of thetreadle 3-1 through a spring 50. This toggle lever is raised to normal position by a spiral spring 51. The use of the spring 50- will be hereinafter described.
Rigidly connected. to and extending laterally from the shafts 45' are a plurality of arms 52 which have their upper free ends connected toslide bars 53; mounted in guides 54 secured to the underneath. side of the ta ble on opposite sides of the slots 55.. Mounted to move on top of the table and extending; longitudinally thereof are separated bars- 56 and 57 which have connected to them the depending legs. 58 which pass through the slots 55- and engage apertures 59 in the slides 53 whereby the bars 56- and 57 will move with the slides when the arms 52' are actuated. by the toggle lever 46.
It will be seen that when the pedal 31 is depressed. and the die holder moved downwardly, the bars 56 and 57 will be moved inwardly toward each other so as to bring the work upon the table centrally under the dies. and that the spring 50'will compensate for any excessive widths in the material to be treated. In other words, if the material is wider than the distance apart of the bars 56 and 57 when brought together by the action of the pedal, the spring will be distended and the material will not be bent upfrom the table.
When the bars 56 and 57 are removed, it
thetoggle lever.
wvill be seen that the table is without obstruction and ready for larger work. In this position, a guide or stop 60 is used which is adjustable laterally across the table by means of an arm 61 secured thereto which passes through an apertured lug 62 carried Y by the table. A suitable set screw 63 holds the bar 60' in adjusted position. This gage or guide is supplemented by an end gage 64 which is adjustably mounted in a piv-- oted bracket 65' and held in adjusted position by a set screw 66. The bracket is pivoted upon the table in such manner that it may be thrown down flush with the topedge of the table whenv not in use, as shown in Fig. 2.
Having thus described the invention, what is claimed is p 11. A machine of the character described, comprising a work table, a frame for supporting the same, a die carriage reciprocally mounted within the frame, pedal and. lever mechanism. for driving: the die carriage toward the work: table, means operated by the pedal. for placing the material beneath the die carriage, means for adjusting the action: of said placing means, and a compensating device for preventing bulging of the material by the placing means.
