STAPLI N'G AND CUTTING MACHINE.

QPEGIFICATION forming part of Letters Patent No..517,58"7, dated April 3, 1894. Application filed February 28, 1893. Serial No. 464,101. (No model.)

To aZZ whom it may concern:

Be it known that we, CHARLES E. PARKS and LoBEeoT'r MOLLART, citizens of the United States, and residents of Watertown, in the county of Jefferson, and in the State of Wis- CODSID, have invented certain new and useful Improvements in Stapling and Cutting Machines; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to the'mannfacture of panels comprising wooden-frames and slatand-wire fabric made fast thereon; its object being to facilitate the production and economlze in the manufacture of such panels.

To this end our invention consists in certaln peculiarities of construction and combination of parts, as well as in a method of panel production hereinafter specified with reference to theaccompanying drawings and subsequently claimed.

In the drawings :-Figure 1 represents a plan view, partly in horizontal Section, of a staple driving and fabriccutting machine constructed according to our invention; Fig. 2, a

vertical longitudinal section of said machine taken on line 22 of the former figure illustrating certain of the parts in elevation; Fig. 3, a vertical transverse section taken on line 3.3 of the preceding-figure. Figs. 4 and 5 are also sections respectively taken on lines 44. and 55 of Fig. 3; Fig. 6, a detail elevation partly in section illustrating aguidestock and, certain other relative parts embodied in our machine; Fig. 7, a horizontal section taken on line 77 of the preceding figure; Figs. 8 and 9, similar views taken on line 9- 9 of Fig. 7 and illustrating two positions' of pivotalstaplestops on the guidestook, and Fig. 10 a section on line'1010 of Fig.4, illustrating a staple guide and guard.

Referring by letter to the drawings A represents the table portion of our machine mounted upon a suitable frame-work. Set in the table and forming part of the same is a transverse metal slabB and secured'to standards b at the ends of this slab are parallel guide-rails O for a staple-driving and fabriccutting mechanism hereinafter described.

Arranged on the table A is a stationary longitudinal gage D and said bed is provided with transverse slots 0 with which the setbolts d of a movable gage E are engaged, the latter gage being arranged parallel to the one first specified. Suitable stops e are positioned on the slab B, and rising above the table A-at one end thereof are standards F of the frameably consisting of end-blockslghaving journals g engaging said side-bars, and a pair of round bars I secured to the extremities of the end-blocks. To one of the tightener journals g is rigidly secured a hand-lever'K, and this lever is provided witha weight L,- designed to hold the tightener in the position to which it may be adjusted.

,In the employment of the machine, a rectangular frame M is positioned on the table'A at that end of the latter farthestfrom the reel G, the gage E having been adjusted toa distance from. the one D equalto the width of said frame. sponding width to the one M, is positioned between the gages D, E, so asto inclose the stops e, on the slab B, and have its transverse member farthest from the reel H in contact Another frame N, of corre- 80 with said stops. vThe fabricis drawn from the reel and carried along between the members J of the lever-controlled tightener to be fastened to that end of the frame M farthest from vsaid reel. This operation being completed the lever K is actuated to change the normal angleof the tightener as shown by full lines in'Fig. 1 and dotted lines in Fig.2, thereby exerting a draw of the fabric toward the rear. This draw brings the frame M snug against the one N and the latter is held fabric equal iri length to the frame farthest from the reel. Owing to the metal slab B there is a good impact of the staple-drivers and less jar of the machine than would otherwise be the case incidental to the stapledriving and fabric-cutting operation. As a result of this operation the first frame, and the section of fabric cut from the web form a panel that is removed from the machine, after which the second frame is advanced beyond the stops (2 and another frame arranged to inclose and impinge against said stops. The operation of tightening the fabric, and of stapling and cutting the same is now repeated, and this method of procedure carried on indefinitely, it being particularly observed that the fabric is made fast to opposing front and rear ends of two panel frames at each operation of the staple-driving mechanism.

The staple-driving and fabric-cutti ng mechanism herein shown involves a carriage consisting of a block P loosely arranged between the guides 0, above specified, and held in place by upper and lower plates Q R joined thereto by bolts or other suitable means and having a width sufficient to overlap said guides and work thereon. Bolted or otherwise rigidly secured to the upper plate Q is a handle S, by means of which the carriage may be moved along its guide in either direction. Adjacent to the handle S is a vertical opening in the carriage, and movable in this opening is a guidestock T for plungers U, each of which latter is provided with a lug it that operates against the inclined inner edges of fingers V pivoted in pairs to the front and rear sides of said guidestock. Shoulders q) in the guide-stock limit vertical movement of the plungers U, and forming an offset lower terminal of each plunger is a blade U that is shown concave at its lower end. Each blade works against a flat spring j fast in the guide-stock for the purpose hereinafter specified. The pivoted fingers V are opposed by springs 70, secured to the guidestock, and retracted against the power of these springs by the action of the lugs h on the plungers incidental to a descent of the latter, the inner lower portions of said fingers being beveled for the purpose hereinafter set forth. Bolted or otherwise rigidly secured to the lower extremity of the guidestock on the plunger sides of the same are vertical foot-pieces m of inclined guides W for series of staples n and supported on each of these guides is a guard X that prevents the staples from jarring out of place. Pivotally connected to a lug p on the sliding carriage are links (1 likewise connected to a weighted lever Y that is also pivotally connected to the plungers U, and the latter are in turn similarly united to a hanger r for one end of a knife Z, the other end of this knife being pivoted in another hanger s that depends from said carriage, as shown in Figs. 3 and 5. In order to permit the necessary play of the knife, the lower end of the guide-stock is centrally recessed, as shown in Figs. 4 and 5.

In practice, the carriage is moved along on its guides to bring the guide-stock in line with a wire of the fabric when the latter is drawn taut on the panel-frames positioned on the machine table, as above specified. Now if the lever Y be actuated, the guidestook T and plungers U will descend together until said guide-stock is stopped by its pressure upon the fabric and frames, but said plungers will continue their descent until stopped by the lower ones of the shoulders t' in the aforesaid guide-stock. By the continued descent of the plungers, their bladeportions U operate to force down the staples that have in the meantime been fed to the guide-stock and held therein by the expansion of the springs j, and thus these staples are driven into the fabric and frames astraddie of a wire in said fabric and on opposite sides of the line of cut of the knife Z, the necessary movement of this knife being due to the action of said plungers connected thereto, and its line of cut coming between the abuttingframe-panels on the machine table. The operation just described having been accomplished the lever Y is released and, by the automatic descent of the weight Y thereon, the several parts connected thereto are returned to their normal position after which the carriage is again moved to bring the guide-stock in opposition to another wire in the taut fabric for a new operation of the stapledriving and fabric-cutting mechanism. From the foregoing it will be seen that the fabric is pressed firmly on the frames and rigidly secured thereto, by the staples that also bind the ends of the wires in each section out from said fabric.

The fingers V, pivoted in pairs to the guidestock T, have their lower ends normally i1npinged against the inclined guides W in the path of staples thereon, but each time the plunger U makes a descent, the lugs 7t thereon actuate said fingers to bring them out of the path of said staples and permit the inner one of the latter on each guide to slide down against the blade portion U of the relative plunger. Upon a subsequent ascension of the blades their lower extremities will clear the staples that have slipped past the retracted stop-fingers and these staples will drop into the guide-stock against the flat-springs j and the inner ends of the guides W, as

shown in Fig. 4, to be there retained until another descent of said blades,and the springs 70 act to return said fingers to "their normal position, as the plunger-lugs h ascend. The lower inner edges of the stop-fingers V being beveled the staples that have come into contact with the blades U are forced into the guide-stock by the return of said fingers to their normal position, incidental to the action of the springs 70, the latter being employed to insure of this return action at the instant the plunger-lugs cease to exertpressure, in order that the' staples remaining on the guides may be held back, and those fed to the guide-stock properly positioned in advance of another descent of said blades.

The guide-stock is shown as being provided with a stop t that comes into contact with the carriage-handle S to limit downward movement of said guide-stock when the latter is not opposed by the fabric and frames and it is desirable to push out some of the staples by an action of the plungers.
