To aZZ whom it may cancers:

Be it known diet I, Hluaizrsori B. Viewer, citizen of the United States, residing at Dan'ville, in the county of Vermilion and Slate or llliuois, have invented ccriain new and. useful improvements in Clenching Blocks for Staplirig-ldechines, of which the following is a specification.

My invention loco improvemenic in clenching blocks and accessories for stapling machines heading solid end fiber boxes.

The invention consists in novel form of clenching block slidebly mounted upon its support so it mey be raised or lowered vertically for the purpose of entering 1311c recessed head or she her during the operation of stitching in rho heads and again for removing box he hood is stitched slight springing mevemeni, away from the stapl I thus ollowme the block to yield to any increased or excessive Szhickncss, due to additional layers in the sock being operatcd upon.

In the eccomp'zmyirig drowings:-

Figure l side elevation of the entire machine showing ahe relation of the parts.

Fig. 2 is 2. view in side elevation of lzhe upper end of stapling machine showing my improvements some. ed.

Fig. 3 is a. top plan view showing the opcrating mechanism.

Fig. l is c side elevation looking from the operating side of machine;

Fig. 5 is 2.11 enlarged side elevation of the clenching-block; and

Fig. 3 is an end elevation of the same. To base 1 is a. vertically adjust able suppers (worrying side members 3 and 4C. In upper ends of the side members 3 and is pivofixeliy recruited 4*, a. stapling machine 5 which is. held against rotation by means of spring bolt 6 and recess 7. The housing for the staple-forming and feeding mechanism is disclosed at 5. A clenching bar 8 ispivota-lly mounted upon the mochinc 5, at 9. Rigidly oilixcd to the clenching bar 8 is a. strong steel spring 10, the tension of whichis ad usted by meens'of the adjusting screws 11. p

Toward the bottom of the clenching bar 8 a' slot l2 is provided, which is adapted to slidably receive the-L-shcpedclenching block 13. The upper portion of the block 13 has rigidly attached fro it side plates 14 and 15. These plates are screwed on to a small block 1 A spring 17 is interposed between a bar 18 and the block 16, and the screw 19 rigidly holds them. together. One end of the spring 17 is adapted to bear against the clenching bar 8 to keep the block 13 in olinement with the slots 12. A cross plate 8 is fastened to clenching her 8 and is adapted to be engaged by the side ple tes M and 15 to limlt the downward movement of the clenching block 13.

r The upper edge of the bar 18 is provided with-en orifice20, through which is passed one end of thebent lever 21, which is pivotolly mounted at 22 upon the top of the side plate 3.

A lever 23 is pivoted at 24: on one edge of the side plate 3. One end of the lever 23 is connected with a link 25. The other end of link 25 is connected to-the lever 21. On the other side of the pivot 24 there is rigidly afixed to lever 23 a bar 26 at 26' which I is connected to the clutch mechanism 27. The lever 23 has pivotal connection with a treedle rod 28. Adjustment of the frame vertically is possible and the lock bolt 29 in the connection 30 permits the trcadle rod 28 to slidelip or down through-the cofmection 30 when the boll; 29 is loosened and when it isiiightened.

will be hel dat whatever positionis desired,

I provide straps 31 and 32 csigui'des for.

the rods 34 and 35, and I also provide turn buckle 33;f01 the purpose of making slight adjustments, between the two rods 34: and

35, which form a continuation of treadle rod 28. Rod 35 is connected at its lower end to the trcadle lever 36, which is pivoted at 37 end is provided with the treadlc 38.

The operation is as follows:

After the stapling machine has been edjusted vertically eeeording to the size ii? the box to be stapled and set rigid res .3 to have the box with inserted heed, run intothe machine for the purpose oi inserting the staples, it will be obvious that the reee head with the flanges engaging the body oi the box would strike the clencbiiig bark the clenching bill must be inside of the below the flanges while the stitches are being put in; and since the operator has both hands engaged while pushing the be}; into the machine, and both hands are further on gaged While sliding the box throogh the machine during the stitching operation, it

' is a areiit that the civic iiip' block must be raised so as to give clearance for the flanges oi the be); head. iliis aceom; Iished by means of the spring 39, connected to lever near the point of connection oi said to link 25. Y

The cienehiiig'bloek 13 normally in raised position permitting the operator 'io slide 2i box under the tepliugg; machine and into positionwithout engaging the flanges of said box with flanges oi. said clenching block 13. After placing it desired the operator places'his foot on the tremjlle 38, pulling the treadle bur doii'nward, and through the lovers 23 and 21 and liiil; forcing the bar 18 doii'iiwsird carrying with it the block 13 and bringing it downward to its operable position.

As soon as the block 13 is in its operable position the rigid bar 26 Will have operated the clutch mechanism 2'? and the step .1 machine will bo m the opermieu oi siiipliifu the heads ii the boxes. The o 'ieratioii wil be continued until the operator removes his foot from the trezidle' 38 when the block 13 will be raised through the bar 18 lower 23, and spring 25). Then at the same t me the bar 26 will operate to Cleo-hitch 7 head and cause it to cease its wei' z and the box may he slid out from under i infuillllllfi.

The tube or body portion of solid end boxes made of one sheet creased and foldml into rectangular form by means of a hipped joint, and these bodies with the inserted head are pushed through the ii'uiohiiie heads and stapled into position to make the finished box. It tliereioie, apparent that there are two thicknesses of stock to be stapled together for the entire eireum 'eiiee except where the hip is encountered at which point there are three thieknesses to stitched.

if the clenching block wa-sliung iii 1-} rigid condition, when the point where three thicknesses would come through is reeohechthe machine would be choked. To overcome this the heavy steel spring- 10 is pTZOVli'lQflfli; the upper end of the clenching her 8, and is en gaged by the adjusting screws 11.
