BY am Patented June 13, 1950 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to improvements in del vices for holding, feeding and closing or crimping hog hooks or rings.

The principal features of the invention are directed to the provision of a device for holding a supply of hog hooks or rings which may be inserted in various materials and for crimping the same and is characterized by a supply of hog hooks which are held together for separation by the device.

Hog hooks or rings, hereinafter called staples, are used for many and various purposes such as for instance to secure adjacent edges of automobile seat covers together. These staples are generally U-shaped having side legs which are inserted through fabric, leather or the like and when so disposed the legs are brought together or into overlapping relation to provide a ringlike securing member.

The device comprises a novel combination and arrangement of parts adapted whereby a stack of staples may be inserted therein and the endmost staple held between relatively movable jaws in such a way that the legs thereof may be inserted in material. The operation is such that the endmost staple is crimped and closed and a successive staple brought into position.

To facilitate efilcient operation the staples are arranged in the form of a stack and are releasably held together so as to be manipulatable as a unit while at the same time successive staples may be separated from the end of the stack by the device. To enhance efliciency and utility the staples in the form of a stack are arranged angularly relatively to the direction of their feeding movement.

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds, the invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Figs. 1 and 2 are plan and side elevational views of a device embodying the novel features of the invention;

Fig. 3 is an elevational view of the forward end of the device shown in Figs. 1 and 2;

Fig. 4 is an elevational sectional view on the line 4-4 of Fig. 1;

Fig. 5 is an elevational sectional view on the line 5-5 of Fig. 1;

Figs. 6 to 9 inclusive are cross sectional views on the lines 6-6, 1l, 8-8, and 9-9 of Fig. 4;

Fig. 10 is a plan view of one of the staples used in the device after being crimped;

Fig. 11 is an elevational view of the forward end of the feed rod and staple propeller with a stack of staples associated therewith;

Fig. 12 is a perspective view showing the lever of the device and operating connection with the jaws thereof; and

Fig. 13 is a perspective view at the forward end of the device with parts broken away for clearness.

Referring now to the drawings more in detail, the invention will be fully described.

A housing 2 is provided which is adapted for use as a handle. Preferably this is in the form of an inverted U as shown in sections in Figs. 6 to 9 inclusive.

The forward end 4 of the housing is enlarged, as shown in Figs. 2, 4, and 5. A lower wall 6 extends longitudinally of the housing and is secured thereto.

A cap 8 is removably secured to the rear end of the housing in any suitable manner and a longitudinal rod l0 projects through the rear side thereof and has a manually engageable member l2 fixed thereto.

A longitudinal guideway is formed on the wall 6 by longitudinal side members [4 which extend upwardly from said wall, see Fig. 6.

The rod H1 is screw threaded in a boss It at the forward end of the wall 6, see Fig. 5, and may be readily connected to and released therefrom. A follower i8 is slidable on rod I0 and it has an inclined forward face or side as shown in Fig. 11.

A stack 20 of staples 22 is slidable along the guideway formed by members [4 and is urged forwardly by follower l3 which is acted upon by a, spring 24 around rod H). The endmost or outermost staple abuts the inner side of jaw members 26 and 28.

The staples are releasably secured by some readily rupturable material such as wax, solder or the like and they are arranged in the inclined relation shown so as to be projected angularly.

According to the invention the means securing the staples in stacked relation will be such that the outermost or endmost staple may be readily removed from the stack. In loading the device the cap 8 is removed from the housing and the rod is unscrewed from the boss l6 so that a stack of staples may be placed in the guideway forwardly of the follower.

An operating lever 3|] is pivoted at 32 to the housing and it is urged in a clockwise direction by a compression spring 34 having one end 35 disposed in a boss 36 and its other end 31 bearing on the inner side of lever 30.

The lever 30 at one side has a curved cam face 38 which works in a concavity 40 of a segment 42 that is pivoted at 44 for oscillations back and. forth. Below cam face 38 the lever 30 is provided with teeth 45 for meshing with teeth 48 of segment 42.

A head 55 is secured to the forward end of the housing and a slide 52 is slidable up and down therein. The parts are arranged so that the slide moves on an incline or at an angle relative to a plane at right angle to the longitudinal axis of the housing. The jaw 28 is integral with head 50 and jaw 28 is pivoted thereto at 54.

A plate 55 is secured to the forward face of the head and. it has offset portions 58 in which a shaft 50 is journalled. Said shaft carries gears 62 and 64 and said gear 62 meshes with slots 6 in slide 52 while gear 64 meshes with teeth 65 of segment 42.

Jaw 28 is urged towards jaw 26 by a spring which has one end 'lii connected thereto and its other end 12 connected to plate 56, see Fig. 3. Inner sides of jaws 25 and 2-8 are provided with slots 14 for receiving and guiding staples when pushed thereinto by slide 52.

A shaft 85 is journalled at the forward end of the housing on an axis parallel to that of rod [-0. Opposite ends 82 and 84 of said shaft are offset as shown in Fig. 12. Shaft end 84 engages a bracket 86 secured to jaw 28 and end 82 is disposed below and acted upon by a cam part 88 on the forward end of lever 30. It will be explained that lever 30 is channel-shaped and at its forward or outer end has cam part 38 and cam part 88 in spaced relation at opposite sides of the guideway for the staples.

As shown, a staple 22 is held between the jaws 2G and 2B. The housing which functions as a handle may be grasped in an ordinary manner and the staple may be inserted in material such as fabric or the like.

With the staple inserted in the material, lever 3!! is moved counterclockwise as by squeezing the lever and handle. This movement of lever '30, which is against action of spring 34, causes cam part 88 of the lever to act on part 82 of shaft 80 so that part 34 of said shaft swings jaw 28 towards jaw 28. The jaws in being closed crimp or close the staples as shown in Fig. 10. During this movement a lever 30 the convex end portion 38 thereof slides on surface 40 of segment 42.

Subsequent to crimping of the staple the lever is re eased and is swung clockwise by spring -34 and teeth 45 of the lever engage teeth 48 of segmcnt so that it is swung counterclockwise. In this movement of segment the teeth 55 thereof in engagement with gear 64 and with gear 62 engaging slots 66 of slide 52 causes the slide to move downwardly so as to remove the endmost staple of the stack and push it into and between jaws26 and 23 so that it is in the position shown.

The invention may be embodied in other specific forms withmit departing from the essential characteristics thereof. Hence, the present emboriiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.
