The invention relates to .a stap e dispenser an more particularly to .a. dispenser. or staples some monly known as hog rings. ;Such;s.taD1 es=.are-.Si1br stantially U-shaped with converging legs pr sides. The .staple is brought somewhat shap of a ring by grasping .the staple with aspen: of pliershaving jaws with offset grooues therein to bend one leg of the staple across the other when the pliers are operated,

While such staplesare employedtoiorm-aring in a hog, this invention isrnore eoncernedwith another well known use, namely, to anchor a seat .cover onto the metalframe work of anautos. mobile seat. The disadvantage in thisuseis that it takes a certain amount of time to place the. stapleinproper relationin the iawspi-thepliem in :the course of iorming the ring. According'to one proposal, a hopper :for the staples has been: mounted on the pliers, but this solution is not.

satisfactory as the hopper is a rather largeprotuberance which interferes with the tree useoithe pliers.

An object of the present invention to overcome the above detects andto providea dispenser which will store a stack of staples sothat are accessible one at -atime for grasping hythe pliers.

According to the invention the stack of staples:

is sliclably supported on a. post having sections, one of which is rigid to prevent "lateraldrawal of the staples while the other section-is: collapsible .to permit lateral withdrawal of: a staple. The invention also provides. means ion feeding the stack of staples fromthe rig-idpost; section to the collapsible section, as well as means: ior guiding the jaws of the pliers into operativerelation with a staple .on the collapsible .seotlon-.

'Eaeh postlike islidaibly supports its'stack' 3 of -staples, and-anew staekoanbe fitted endwise on the post. a

Each stack ofs-taples has on topthereof a sliding weight like 22; seeFig. 5, each such weight having an aperture o-f'thesame contour as-the post like 4, and each such weight: at the front and sides of such post having a downwardly extending sleeve extension 2 3, see Fig. 5, to force the staples into the tilt head 16.

M- as s n i Fig,- servssas a .mask and has a som ha U -.shaheo sl 2. 19! the same shape as, and slightly larger thanthe table so tha h n a t cular o t such s in a i nmen w th th sl 2 th st p s th h s ch slo and on i a lowe o t it. s e F :1. The po is. statio ary and -has a som what u-shapoo c nt ur- 1 the same hat f he in id o ihsst hlsi ks? the 8 ms 3 the contour 3| of the staple guiding portion in alignment with the slot 25.

Each post like 4 is brought into alignment with the fixed post as follows. The post 30 has a spring barrel for a compression spring 4| which urges upwardly a ball detent 42. The stop plate [4 has a restricted aperture 43 smaller in diameter than th ball so that the stop plate l4 serves as a retainer for ball 42. Ball 42 projects above the top of plate l4 and engages a recess like 45 in the bottom of each post like 4. When the ball 42 is in a recess like 45, the post like 4 is in l alignment with the slot 25 and with the fixed post 30.

The staples like 2 slide down the post like 4 and the post til, under action of the weight 22. Removal of the bottom staple of a stack is made possible as follows. The front upper portion 5| of the recess 33 is enlarged opposite the staples so that they can slide downwardly into the head It, to a point opposite a lateral opening 52 where the stack is supported by the shelf portions 53, 54 on a collapsible post 55. The shelf 53, 54 is elevated above the bottom ll of recess 33 to receive the pliers 15. The post 55 comprises post portions 55 and 51 each hinged to the bottom of post 30 by a screw like 58, see Fig. 5. The post portions 55 and 5? are urged apart by a compression spring 59, see Fig. 6, having ends arranged in spring barrels and 6! in the members 56 and 51, respectively. The separation of the post portions 56 and 57 can be adjusted by two adjusting screws 62 and 63 arranged in the head [6. The screws 62 and 63 are adujusted so that the staples like 2 will slide down post 36 onto, and be supported by, the shelf portions 53 and 54, with the staple fitting the L-shaped surface 64 on the member 56 and the L-shaped surface 65 on the other member 51. The L portions 64 and 65 form a continuation of the corespondin side and front portions of the post 3|, with a gap 68 opposite the middle of the bight of the staple between the members 56 and 5! so that they can be compressed against the action of spring 59 to a width less than the minimum width between the staple legs to release the bottom staple 50 of a stack. The height of the members 56 and 5'! is preferably slightly greater than that of the lowermost staple 50, as shown in Fig. 5 so as to facilitate removal of the bottom staple.

The lateral opening 52 is flared out as indicated at 70 in Fig. 6, and the vertical opening 5| is wide enough at opposite sides of the collapsible post 55 to permit entry of the jaws II, 12 of the pliers 15.

The jaws H, 12 are shown in section in Fig. 2 and each has a shallow groove I3, 14, respectively,

as well known, to grasp the opposite sides of the' staple, the jaws H, 12 being ofiset so that the legs of the staple will cross when the jaws of the pliers are squeezed together.

A bottom staple 5!] lies in a plane at right angles to the post 30, and to compensate for the fact that jaws H, 12 and their grooves 13, I4 are ofiset, the jaw openings l0 and 52 are tilted slightly as shown in Fig. 2 so that when the jaws H, 12 are inserted, the grooves 13, 14 are opposite the sides of the staples 50 in position to grasp the staple 50.

When the bottom staple 50 is grasped by the pliers 15 by pulling on the pliers, the bottom staple 50 is pulled off from the collapsible post 55, against the action of spring 59. The next upper staple 16 drops into position on the shelf (iii members 53, 54 ready to be again grasped and removed by the pliers 15. After a particular stack of staples has been removed by the pliers, the sliding weight like 22 is lifted and the turn table 9 rotated to bring the next post like 5-8 with its stack of staples thereon, into position as shown in Fig. 5.

If desired, the tilt head [6 can be tilted more or less to suit the convenience of the operator and for this purpose the tilt head has a clamp screw to releasably clamp the axle 81 on the base 82. The base 82 has suitable apertures like 83 for bolts to hold the base to a suitable support.

If desired, one may dispense with the plurality of posts above indicated as well as stop plate I4, and use a single post instead, such post being the same as post 38 in Fig. 7 except that it would be somewhat longer like post 4 in order to hold a stack of staples.

Various other modifications may be made in the invention without departin from the spirit of the following claims.

' We claim:

7 l. A dispenser for staples each substantially U-shaped and having converging sides, said dispenser comprising a post adapted to support a stack of such staples for longitudinal sliding movement thereon, said post having a contour substantially the same as the inside of such staple and having a front portion wider than the minimum width of the legs of the staple to prevent lateral withdrawal of the staples from said post, said post having a conjoining collapsible post, said collapsible post having a shelf to support the end staple of a stack, said collapsible post having a height at least as great as one staple and less than two staples, said collapsible post having a contour fitting the inside of the staple at certain times and being collapsible to permit lateral withdrawal of a staple.

2. A dispenser according to claim 1 wherein said collapsible post comprises an opposite pair of post sections, a hinge connection between each i of said sections and the bottom of said first post,
