STAPLINGeNIACHINE.

SECIFICATION forming part of Letters Patent No. 500,576, dated July 4, 1893.

Application led August 25, 1892. Serial No. 444,141. (No model.)

To all whom, t may concern.-

Be it known that I, GILBERT HAY, a citizen of the United States, residing at Fayette, in

the county of Howard and State of Missouri, have invented a new and useful Stapling- Machine, of which the following is a specification.

This invention relates to certain new and useful improvements in stapling machines, and it has for its object to simplify the construction and arrangement of the parts thereof for more direct and positive action and to render the same strong and durable.

The invention consists of the construction, arrangement, and combination of the several parts as will be more fully hereinafter described and claimed, and which constitute an improvement on patents numbered 461,337, dated October 13, 1891, and 477,117, dated J une 14, 1892, which have been granted to me.

In the drawings :-Figure 1 is a perspective view of the improved machine. Fig. 2 is a longitudinal vertical section thereof on the line w. Fig. 1. Fig. 3 is a detail perspective view of a part of the staple feeding mechanism. Fig. 4 is a similar view of the saine mechanism with the parts disconnected. Fig. 5 is a perspective view of the brush arms.

Similar numerals of reference are employed to indicate corresponding parts in the several figures.

Referring to the drawings, the numeral 1 designates a suitable base upon which is mounted an upright 2, having the upper end thereof slotted as at 3,' and provided with horizontal arms 4 and 5 extending forwardly one above the other. The upper arm 4 has a vertical slot 6 formed in its outer end to receive a vertically movable or reciprocating slide 7, which consists of a tube rectangular in cross section and of suitable dimensions to admit of the passage of a staple of the desired size therethrough. The upper end of the tubular slide 7, is provided with a flange 8, and the said tube is made of such a length that when the iiange 8, rests upon the upper side of the arm 4, the lower end of said tube will almost reach the arm 5. The said arm 5 is provided with an anvil 9, with a depending stud or rod 10, adapted to bear upon a yieldingcushion 1l, at the lower end thereof. A punchl or staple driver 12, is mounted to slide vertically in the tube 7 and is formed with a slotted head 13, between the lower portion of which and the flange 8 of the tube 7 is mounted a coiled spring 14, which normally holds the said punch or staple driver in raised position together with the parts carried thereby, it being understood that the lower end of said punch or staple driver is recessed to engage the head or arch of the staple. A fulcrum post 15, rises vertically from the arm 4, and therein is pivotally mounted alever 16, whose front end is also pivotally connected in the slotted head 13, of the punch or staple driver and to the rear end of the same is attached a pitman 17, from a suitable treadle or other motive power commonly employed in this class of devices. On the front portion of the said lever 16 is secured one end of a flat spring 18, which is bent in curved form and loosely eX- tends over the head 13, of the punch or staple driver for a purpose which will be presently explained. In rear of the fulcrum post 15, the lever 16 is provided with an eye or ear 19, for a purpose which will also be hereinafter stated. The front side of the vertically movable or reciprocating tube 7, is provided with an opening 20, which, when the said tube is in arranged position, registers with an opening or the lower end 21, of a feeding chute 22, which is secured obliquely to a plate 23 attached to the front portion of the arm 4, which has a slot 24 therein through which the said feeding chute passes. The said feeding chute extends upward obliquely away from the arms 4, some distance above the head 13, of the punch or staple driver and in connection with the plate 23 immediately below the said feeding chute is located a horizontally disposed spring actuated stop pin 25, which enters the slot in the front end of the arm 4 through the plate 23 and into the tube 7, to

limit the downward movement of the staples through the tube from the feeding chute and allow only one at a time to pass into said tube 7. It will be seen that the said vpin is located at the lower termination of the feeding chute and thereby the operation set forth practicably ensues.

From the upper portion of the upright or standard 2, rise vertical arms 26, having the upper ends thereof secured to a circular staple feeding box or chamber 27, which is disposed IOO at an angle of inclination and is supplied with a hinged cover or lid 28 in the upper side thereof and an opening 29 inthe bottom thereof adjacent to one edge of the same. The said opening 29, is formed as a guiding groove terminating in an opening in the bottom of the said box or chamber which is covered by the upper end of a guide trough 30, extending away therefrom in a downward oblique direction and of such size as to allow staples to pass freely therethrough by gravitation.

The box or chamber 27, has a shaft 31, extending centrally therethrough with a gear 32, attached to the lower end thereof which measures with a mutilated or partially cut gear 33, mounted on a suitable revolving shaft 34, and to the said gear 33 is eccentrically connected the upper end of a pitman 35, said pitman having its lower end secured in the ear or eye 19 on the lever 16. On the `said shaft 31,are mounted radiallydisposed brush arms 36 in line with each other diametrically across the box or chamber 27 and formed with separated or spaced brush sections 37, which travel close to the bottom of the said box or chamber 27 in an oscillating manner. The oscillation of the brush, the said arms, and brush sections carried thereby, arises from the construction of the mutilated or partially cut gear 33 and the connection thereof with the lever 16, the latter, being understood, having a vertical reciprocating movement. By constructing the brush sections with intervening spaces between the same, clogging of the staples within the box or chamber 27, at the feed opening where the trough 30 is connected, is ohviated, as it will be seen that by said construction a portion of the staples at times will not be engaged by virtue of the spaces between the brushes passing over the same.

To the lower end of the trough 30, is secured a feed slide 38, consisting of a rectangular metallic bar which is partially covered bya guard 39, to hold the staple moving over the said slide in proper position,it being seen that the guard has depending flanges extending over opposite faces of the said slide. The slide 38, extends over and beyond the head 13, of the punch or staple driver clos'e to the adjacent upper end of the feeding chute 22, which has a rear opening 40 at this point through which the staples pass from the said slide 38, and above and below the said opening 40 are guards 41, which prevent dropping of the staple away from the said feeding chute 22.

vertically rising from opposite sides of the arm 4 is a pair of arms 42, arranged at an angle of inclination toward the front of the machine and having their upper ends reduced and formed into channel guides 43, and said arms at the rear upper portions are braced by beingconnected bya cross strip 44. Between said arms 42 and mounted in the channel guides 43, thereof is movably mounted a plate 44, having a slot 45 extending therethrough and of suitable length and width to permit the passage of a staple. The opening 45 through the said plate 44, is reduced at the upper and lower portions thereof by plates 47 and 48 secured respectively at the upper and lower portions of the front and rear sides thereof. These plates 47 and 48 are bifurcated or slotted as at 49, and the legs 50 on each side of said bifurcations or slots thereof partially extend over the slot 46 of the plate 45 and reduce the Width of the same to less than the width the legs of the staple are apart from each other and coact to permit the feeding of one staple at a time through the slot 46 of the said plate 45. The slide 38 extends through the plate 45 and is alternately embraced, in operation, by the legs of the plates 47 andv48. The lower plate 48, holds the staple on the slide 38 until the punch or staple driver descends and forces the staple already fed into the tube '7, out of the latter, and when the said punch or staple driver rises the plate 45 is also pushed 'upward through the medium of the spring 18 on which it bears and the plate 47, catches the next staple advanced on the slide 38, it being observed that the distance between the plates 47 and 48 being about the same as the space occupied byone staple on the said slide 38 and also that the legs of the plates 47 and 48 are so positioned that when said legs of the plate 48 clear the slide 38, the legs of the plate 47 will have already passed partially over the said slide 38 and thereby the movement of the staple being fed is limited. This operation becomes successive and is controlled by the downward movement of the punch or staple driver to feed the staple and by the upward movement of said punch or staple driver to hold the staple yon the slide 38 ready for feeding, if ahead.

It will be seen. that the operation of this machine is positive and direct acting and that the parts all work simultaneously and automatically. The construction is comparatively simple and is reduced in cost to a minimum.
