J; woLF Y STITCHING MACHINE Filed Dec. 27, 1926 ,'5 Sheets-Sheep Cil screw 49 and the boss 44 of the swinging bracket 40. The bearing portion 39 of the pivoted braeket 40 extends through a relatively enlarged aperture 51 Vformed in the A`plate 14. From the above' description it will be noted that by reason of the pivoted bracket 40 and compression spring 50, which norm ally presses the pivoted bracket in a downward direction, that the feeding surface 38 of the feed roll 37 is thereby resiliently pressed into engagement with the feeding surface -34 of the cam 33 when the wire is gripped between these .feeding surfaces in the operation of feeding the wire. rlhe feeding mechanism may lbe adjusted to feed wires of varying 4lengths by adjusting the feed roll 37 in such a manner that the wire feeding surface 38 cooperates during a greater or less portion of' vwith the main drive shaft and thereby reduced the size of the machine to a considerable extent.l
Formed in the front side of the plate `14 is a usual staple forming channel 51" having reciprocally mounted therein a staple former 52which in turn is provided with a vertically extending channel 53. The channel 53 of the staple'former 52 has reciprocally mounted therein a staple driver 54. The staple former 52 is operably driven to form staples by the cam 32 which engages a roller 55 journalled on a pin 55 secured to the rear side and upper end of the staple former. The staple former is normally returned to its uppermost position by the compression spring 56 which is seated in a socket 57. formed in the forward side of the plate 14 adjacent ther staple former. The upper endv of the compression spring 56 is positioned in a tubular member 58 which normally engages the pin 59 secured to the rear side of the staple former just below the roller 55. The tubular member4 is reciprocally mounted in the socket 57 as clearly shown in Fig. 2. The staple driver 54 isoperatively driven by the usual pitman connection 60 which has one end thereof connected, as shown at 61, ec-
, centrically with respect to the axis of the cam 33 and the other end thereof connected, as shown at 62, to the upper end of the driver. Clo-operating with the staple forming and driving mechanism is the usual anvil 63 vand staple supporter 64.Y The anvil 63 is provided with a wire groove 65 and a compression Vspring 66 which normally forces rThis is done by adthe anvil out into the path of the staple forming and driving mechanism. The staple sup- -of this mechanism is thought unnecessary.
Adjustably mounted adjacent the staple forming and driving mechanism .is the improved wirc cutting mechanism which coinprises a horizontally adjustable block* 68V which has aV rearwardly projecting extension portion 69 which is adapted to slidingly cngage a channel 70 formed in the forward face of the plate 14 for horizontally adjusting the block 68 with respect to the formingand driving mechanism. Mounted in the block 68 and secured therein, in any well known manner, is the usual cutter tube 71. Secured to the block 68 at the opposite ends thereof and extending upwardly therefrom are two guiding pins 72. Reciprocally mounted on the guiding pins V72 is a cutter block 73 vand secured to the cutter `block 73 on the. side` adjacent the staple forming and driving mechanisml by means of' a lscrew 74 is the usual Y knife 75. Formed on the inner side of and adjacent the top of the cutter block 73 is a projecting ange 76 having thereunder an undercut channel 77. Intermeshing with the flange 7 6 and undercut channel 77 in a manner to engage andy operatively actuate the cutter block 7 3 is a reciprocally mounted plate 78 which is positioned between thefront plate j 79 and the main plate 14 of the stitcher head.
`The front plate 79 is secured to the main plate 14 by means'ofrmachine screws 79. The front plate 7 9 is provided with an offset portion, as shown at 80, forming a shoulder 80 which forms astopfor the upward movement of the cutter block 73. The cutter block k7 3 together with its reciprocally mounted plate 78 is normally actuated to its uppermost position by a compression spring Y 81 which is seatedl in the recess socket 82 formed on the front side ofthe plate 14, as shown in Figs. 3 and 4. The upper end of the compression spring 81 is adapted to have seated thereon the head 82 of a spherical headed pin 83 secured to the rearside of theV reciprocating `plate 78 in any well knownk manner. The plate 14 is slotted, as shownat 83, so as to permit the spherical headed. pin to reciprocate in the operation of severing the wire. The cutting mechanism is actuated to cut the wire by a' level-84 pivoted at 85 to the plate 14. The lever 84 has an upwardly curved portion, as shown at 86, which is adapted to be engaged by a cam por-` tion 87 formed as an integral part of the wire feeding cam member 33. The lever 84 is furllll iso
l ther provided with' a-laterally projectinglpor- 89 and a lock nutQO. The-lower endof the adjusting screw 89 is adapted' toA engager the upper porti'onl91 of the reciprocally. mounted plate 78. By this construction it .willbereadily seen that during each'cycle of operation thefcani surface-87 of the cam 33 will engage the free end 86 of the lever 8a and swing said lever in a counter-clockwise direction, thereby forcing the reciprocating plate 78 downwardly with its cutter block 73 and actuating the knife to cut the WireeXtending through the cuttertube 71. In connection with adjusting my improved cutter block horizontally with respect to the staple forming and driving mechanism I have provided a series oftaperedor conical cavities 92 which are adapted to be engaged by a tapered or conical point 93 of a thumb screw94. The thumb screw 94 is in threaded engagement with the front plate 79, as shown at 95.
F rom the above description it will be readily understood that when it is desired to adj ust the cutter block 73 together with the cutter tube and block 68, the thumb screw 9st is unscrewed from engagement with one of the f cavities 92 of the bloclrr 68 and the cut-ter In this adjustment it will, of course, be understood that the cutter block 68 is adjusted longitudinally of the plate 14; by the rearwardlyy extending` projection 69 engaging the channel formed in the forward face of the plate 14, and when the predetermined adjustment of the cutter bloclr has been determined,
the thumb screw 94 may be tightened to se-` cure-or clamp the cutter block in a relatively hired position with respect to the staple forining and driving mechanism.
In the operation of the above described de- Y vice it will be understood that the wire is fed from the spool 17 aro-und the semi-circular guide 19 through the wire straightener and wire checking devices 2O and 21 respectively, where it is engaged by the feeding surfaces 38 and 34: of the feed rollers and feed cams 37 and 33, respectively,through a circular guide tube 96 into the main tube 71 where it passes into thegroove 6'5 formed in the front end of the anvil 63. After the. Wire is thus fed the cam portion 87 of the wire feeding cam 33 engages the free end of the cam 86 and actuates the lever about its pivot 85, depressing the cuttingmechanism through the. reciprocating plate 7 8 against the tension of the compression spring 81, thus causing the wire extending through the tube 71 to be severed adjacent the staple forming and driving mechanism. Simultaneously 'with the severing of thevwvire, the cani 32"engagesthe roller 55 journalled :totheVV rear; sidef of they'stapl'e former "5'2-and depresses the staple former 52 against the act-ion of theconipression spring 56. vAt the completion of the staple forming operation? the staple driver 54%is then actu ated through the 'medium of the pitma'nl connection 60 v in drivingitlie :staplefintof the work beneath the head 'ofthe.stitchingmacliine Itwill, of course, be understood that the anvil 63 is forced from the path of the staple forming and driving mechanism by the staple driver which engages the bevelled front face of the anvil in its downward movement and then the staple supporting member 64 is likewise forced outwardly by the downward movement of the staple driver as it is completing its work in driving the staples'.
From the above description it will be readily seen that I have provided a very simple and efficient Wire stitching machine and one in which the parts are reduced to a minimum and at the saine time I have retained a wide arrangement of adj ustments.
It will be further noted that by mounting one of the wire feeding cams of the feeding 'mechanism' on the main drive shaft or an extension thereof that I have provided a construction in which all of the part-s are coinpactly arranged and the number of parts reduced to a minimum, thereby reducing the manufacturingcost and also reducing the wear on the voperative parts of thermachine.
- IVhile in the above specification I have described one embodiment which my invention may assume in practice, it will of course be understood that the sanieis capable of modiiication, and that modification may be made without departing from the spirit andscope of the invention as expressed'in theV following claims.
The subject matter described and claimed in this application is disclosed in a joint application filed by John Wolf and Ernest Leschorn, Serial No. 737,230 lil-ed Sept. 12, 1924, in which application the subject matter herein claimed was inadvertent-ly set forth as being the joint invention of the said applicants, Volf and Leschorn. This application may therefore be termed a continuation of the joint application.
