To all when?) it ntag concern:

Be it known that I, FEEDRIcK P. ANGELL, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and tate of Michigan, have invented certain new and useful Improvements in stapling- Machiries; and I do hereby declare the following to be a lull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the marks of reference placed thereon, which form part of this specification.

My invention relates to machines for driving staples within the adjacent edges of staves comprisinga wooden column from the interior thereof; and the object of the present invention is to so construct a machine for the purpose that a column built therewith will be very rigid and substantial, whereby the work can be speedily performed, and whereby the machine will be comparatively simple in construction, positive in operation, and easily manipulated.

Other objects and advantages will hereinafter appear in the novel construction, combination, and arrangement of parts described and claimed, and illustrated in the accompanying drawings, wherein Figure 1 is a sectional longitudinal view showing the machine in readiness for placing a column on the stapling mandrel or anvil. Fig. 2 is a rear end elevation. Fig. 3 is a detail side e evation of the staple-feeding mechanism. Fig. 4 is a detail front elevation of the presser-foot head with the presser-foot nearly elevated. Fig. 5 is a detail front elevation of the presser-foot head with the presserfoot at a downstroke. Fig. 6 is a longitudinal cross-section of the presser-foot. Fig. 7 is a detail longitudinal section of the anvil with the cap removed and shows the stapledriving bar in position for forcing a staple within a column or other article placed on said anvil as in Fig. 9. Fig. 8 is a plan .view of Fig. 7 with the cap intact. end view of the anvil with the end. cap re moved and shows the staple-driving slide with a staple driven within the adjoining edges of two staves comprised within a column. Fig. 10 is a cross-section of an anvil l with I Fig. 11 is an end view of the anvil withthe end cap intact.

Fig. 14 is a perspective view of the stapledriving slide. Fig. 15'is a perspective section of a wooden column banded preparatory for driving staples to secure the same together, and Figs. 16 and 17 are perspective views of staples employed upon the ntachine.

A represents the standard to the machine B, an overhanging arm C, the drive-wheel; D, the main shaft; E, the colu1rn-holdihg anvil and staplereceptacle; F, the staple feeding mechanism, and G a pieced wooden column.

The arrows indicate the revolving direction of the operating parts.

The standard A has a forwardly-projecting foot, as shown, with a widened flange for securing the sarre to a floor by means of bolts or lag-screws, the foot portion being alined with the anvil E and arm B to counterbalance the machine. The arm B may coir.- prise a part integral with, but by preference is secured to the standard by means of boltsas shown. Within this arm the operating, shaft D is revolubly securedat either end in boxes, as shown. At a point below the arm and alined therewith the detachable steel anvil E is secured. This anvil is tapering and is fitted within a corresponding-shaped hole through the standard and secured in place by means of set-screws 1, the upper face of the anvil preferably being parallel with the floor.

As shown in Fig. 10, the anvil has a longitudinal groove comprising a series of different widths, the upper portion of the groove being the widest and shaped to form ledges on either side for seating a cap H. Below this cap the groove is formed to provide a stapleholding receptacle or chamber I, and below the chamber the groove is narrowed and forms a guideway for a reciprocating stapledriving bar J. This bar is longitudinally grooved along its top and bottom edges and adapted to receive a small wire cable 4, which runs over grooved rollers 5 and 6, the former being located Within an aperture near the forward end of the bar, the latter being suspended below the bar between ears 7 de pending therefrom, as shown. Secured at one end of the cable and adapted to slide within the chamber I above the bar a staplecarrier 8 is provided, the opposite end of the cable passing over the pulleys ,5 and 6 and winding about a spool actuated by a rack and-gear mechanism F, hereinafter more fully set forth. Within the forward end of this bar a wedgeshaped sliding cam 9 is secured, and it is adapted to work through a slot 10 (see Figs. 1 and 7) in a cap-piece 11, screwed on the end of the anvil E. This cappiece is grooved out at its inner side and when fitted to the end of the anvil provides a slot 12, within which the staple-driving slide 13 is adapted to work. The staple-driving slide comprises a rectangular metallic piece having a longitudinal sloping-topped aperture 14, through which the cam 9 is adapted to play, the slope of the aperture being adapted to fit the tapering side of said cam. The upper or face side of this slide is alined with the bottom of chamber 1 when in a normal or lowered position, so that a staple when forced forward by the carrier 8 will lodge upon the top thereof, as shown in Fig. 1

Within the chamber 1, above the stapledriving bar J, the staples 15 are distributed side by side with their points upwardly and transverse to the cross-section of the anvil E, as shown, and fitted above the staples within the widened mouth of the chamber I the chamber-covering cap H is fitted, its forward end terminating even with the end of the anvil, as shown in Fig. 3.

To the rear end of the staple-driving bar a pin 16 is transversely fixed and engages the lower extremity of an actuating-lever 17. This lever works from a bracket 18, bolted to the standard of the machine, and its upper extremity is provided with a friction-roller 19, engaging with a rotary cam 20 on the driving-shaft. From the axle 21 of said lever an arm 22 extends, to the extremity of which a coil-spring 23 is hooked, and engages at its opposite extremity with a hook 24, bolted tothe machine. The object of the spring is to keep the friction-roller 19 always in engagement with the cam 20. The cam 20 is formed with an abrupt spiral-shaped race and is adapted to cause the lever 17 to oscillate when the shaft D rotates. At the opposite end of the shaft an internally-milled cam 24 is fitted. This cam has a spiralshaped groove 25, within which a frictionroller 26, secured'to a cross-head 27, is adapt ed to work. The shape of the groove is such that the roller 26 will be forced to the center of the cam when rotated toward the right, as shown in Fig. 5, and release said roller upon a further rotation thereof. A coil-spring 28, placed about the upper extremity of the cross-head, fixed between an eyelet 29 of the bracket 30 and a collar 31 to the cross-head,

causes the roller 26 to regain its normal position Within the cam, and that the roller will not strike the cam abruptly on its return movement upward I provide a strap 37, one end of which is secured to the collar 31, its opposite end passing about the periphery of the cam and fastening to the eyelet 29. This strap is taut about said cam when the cross headis in an elevated position and slack when in a depressed position, as shown in Fig. 5. The stem to the cross-head works vertically to the axis of the driving-shaft through eyelets 29, 32, and 33 of the bracket 30. At either side of the friction-roller 26 and adapted to bear against the face of the rim to the cam 24 friction-rollers 35 are secured to the cross-head by studs 36. These rollers prevent the cross-head from turning in its bearings and always keep the friction-roller 26 in working position with the cam. Within the lower extremity of the cross-head a longitudinal here is provided and forms an air-chamber 38, within which a piston 39 is fitted, and that the piston will keep its position within the cross-head a longitudinal slot 40 is made in the side of the air-chamber, .near the bottom thereof, and a pin 41 screwed within the piston and adapted to work within said slot. The lower end of the piston is provided with a longitudinal threaded hole, within which the threaded shank of the presser-foot 42 is fitted, a lock-nut 43 being placed thereon to secure said presser-foot from turning after having been locatedv in a working position.

The staple-feeding wire 4 is operated by a gear mechanism F, bolted to the rear of the machine, as shown. The mechanism chiefly consists of a spool 44, to one end of which a spur-gear 45 is attached, a larger gear 46 meshing therein. A small gear 47 is secured to the axle of the gear 46, and a rack 48 meshes with the gear 47 said rack being longitudinally operative through ways in the extremities of arms 49, said arms forming a part of the bracket 50. The s1 001 and its driving-gear 46 are supported on axles revoluble in a common plane from arms 51 of the bracket 50. To the upper extremity of the rack 48 a weight 52 is secured and causes the rack to actuate the gear mechanism and wind the cable 4, by which means the staples within the chamber I of the anvil E will be fed to the staple-driver as the machine is operated.

To one side of an upper arm of the mechanism F a gong 53 is secured, and an arm carrying a hammer 54 is pivotally attached in such manner that when the weight 52 descends it will hit the arm and cause the hammer to strike the gong. By this provision the operative will be informed when the staples are exhausted, and thereby cautioned to replenish the machine with staples, the staple-feed slide 8 being engaged in such manner that when the wire cable 4 has coiled the column may sufficiently about the drum 44 and moved the slide to the outer extremity of the anvil the weight 52 will ring the gong.

A foot-lever 5'5, conveniently located near the extremity of'the anvil, gives the operative control of the machine. To the op' osite' end of the foot-lever shaft a crank 56' is attached. This crank connects with a tripping-lever 57, pivoted to the extremity of an arm on the bracket 18 through the medium of a connecting-rod 58, and a dog 59, operative from a collar 60, secured to the driving-shaft, engages the tripping-lever 57 to operate the machine.

The driving-wheel C is loose on the shaft and only actuates the machine when the footlever throws the dog 57 in engagement therewith, the mechanism for the purpose not differing from that used on power-presses for a like purpose.

The operation of the machine in the main will have been apparent from the foregoing description. Staples having been supplied to the receptacle I within the anvil E and the cap H having been placed to close the staplefeeding chamber, the staple-feeding guide 8 being brought to bear against the staples, a column G isplaced over the anvil so that two adjoining edges of staves thereof will be alined with the upper face of the anvil. The foot-lever 55 being depressed will cause the dog 57 to lock the driving-wheel O to the shaft D. As the shaft revolves the cam 24 will move the presser-foot 42 downward and hold the column firmly against the anvil at a point immediately above where the staple will be driven. The cam 20 will likewise revolve with the shaft D and move the lever 17 and cause the sta ledriving bar J to slide inwardly, bywhich means the cam 9 will raise the slide 13, carrying a staple, and force the prongs thereof upwardly within the adjoined edges of the staves comprising the column and prevent the same from separating. The mechanism can be stopped as each staple is driven, as maybe deemed expedient, it being necessary to slide the column along on the anvil as the work progresses, so that be stapled the whole length thereof. One row of staples having been driven, the column is rotated on the anvil to permit a second and succeeding row of staples to be driven until the column is finished.

It will be apparent that various changes in the form and minor details of construction could be resorted to without departing from the spirit or sacrificing any of the advantages of my invention, and I hold myself as entitled to such minor changes in its construction as compatible with the spirit of my improvements.
