CLIP.

Application filed May 19, 1919.

To all whz In it may concern:

Be it lLZlOWIl that we, CHARLEs W. Cass and WILLIAM L. Bnx'rnu, citizens of the United S'ates of America, and residents of Salem and Beverly, res 'iectively, in the county of Essex and State of Massacl'nrsetts, have invented new and useful Improvements in Clips. of which the follow mg is a specification.

This invention relates particularly to clips for attaching skins, hides, pelts, and the like to a supporting frame such as dis closed in our former eopendiug application Sr. No. 288,638, filed April 8, 1919, this application being in part a continuation of the former application.

The drying apparatus for this purpose heretofore provided and in common use is of two distinct types; the first is a board upon which the damp skin is stretched and secured by tacks driven through the edge portion of the skin into the board. This apparatus is objectionable for many rea- The skin or other stock is necessarily damaged by the tacks. and as one side of the skin lies against the board the drying process is seriously retarded. The boards soon become very dry and hi hly inflammable undcrthe heat of the rying room, thus increasing the fire risk; and they wear out re idly in service because the tacks have to be riven into substantially the same part of the board, with the result that that particular surface soon becomes disintegrated and the tacks will not hold under the strains exerted by the drying skin.

In. the attempt to eliminate the defects of tacking, so-called, drying apparatus has been provided. comprising essentially an open frame in which the skin is stretched for drying by strings having at one end a metal clip or toggle which grips the skin, the other end of the string being secured to tl1e.frame \Vhile these frames do away with the damage to the skin caused by the tacks of the older device; and both Sides of the skin are exposed during the drying process, they are 'very unsatisfactory in service. A relatively large number of strin Q are required which, notwithstanding t e exercise of due care, become tangled when a skin isplaced upon the frame or removed therefrom. It. takes a relatively long time to string and stretch the skin upon tlie frame and to remove it; the length of the strings has to be changed for each Specification of Letters Patent.

skin placed upon the frame. and the strings stretch individually under the strain of the drying skin so that a uniform strain is not nmioiniued upon the skin during the drying process. i

In our said l'oruu-r application we disclosed on improved support for drying hides and the like comprising :1 Frame and one or more she-ts of -\ll( mesh or other l ornminailed or reticular mat rial yieldingly ste n-lied in the frmue. i fitciilltfl with improved rlips for attzuiihingx :1 hide to the formninutwl sheet around the edges of the hide. the clips having movable jaws adapted to grip the hid therebetween and having spurs adapted to hook into the openings of the toraminated support. The invention herein claimed comprises said clips together with nuulificutions thereof.

The object of this invention is to provide clips which will securely grip damp and slippery hides and the like, which may be rem ily attached or detached to or rom the stock, preferably with one hand. which may be readily hooked to or unhooked from. a suitable support. preferably by one hand while the hide is being stretched, and generally to simplify arl facilitate both the construction and operation of the clips.

In the accompanying drawings,-

l igure 1 is a side view of one embodiment of the invention, showing the clip in closed position;

Fig. 9 is a similar view showing the clip in open position;

Fig. 3 is a central longitudinal section of the clip;

Fig. 4 a side elevation of another em hodiment of the. invention. showing the clip in open position;

Fig. 5 is a ventral longitudinal section of the (lip shown in Fig. 4 with the finger ring omitted, showing the clip in closed position:

Fig. (3 is a side view of the clip shown in Figs. 4- to 5. viewed from the right-hand side of Fig. 4;

Fig. 7 is :1 side view of still another form of clip;

Fig. 5 is :1 side elevation of the same clip viewed from the. left of Fig. 7; and

Fig. 9 is'n ventral longitudinal section, on an enlarged scale. of the stock-engaging lip of the clip shown in Figs. 7 and 8.

The clip shown in Figs. 1, "2 and 3 com prises a band 1 m" flexible steel or other suitable material bent until the ends are disposed in 'uxtaposition. The jpxta osed ends of the cli are bent to form inter tting lips 2 and 3 a apted securely to grip a hide or the like when forced together. On the is hand side of the clip near the upper end thereof, a spur 4 is struck-up for the purpose of hooking the clip. into a sheet of wire mesh or other foraminated support such as disclosed in our prior application, this spur facing toward the'stodc-engaging end of the clip. On the same side oi the clip near the stock-engaging and two ears 5 andfi are struck-up from the opposite sides of the 'band 1, these cars extending substantial] perpendicularly from the lefthand si e of the clip to opposite sides of the right-hand side of the clip. Pivotally mounted in the ends of the ears 5 and 6 is an arm 7 which has an inner end 8 rejecting at approximately right-an les rom the outer end thereof. The arm is preferably pivoted to t e ears 5 and 6 by means of pivot lugs exten ing outwardly from the arm in the region of the 90 bend into openings in the ears 5 and 6,'the ends of the pivot lugs being riveted over if desired to prevent the lugs from pulling out of the openings. These parts are so arranged that the pro jecti end 8 en ages the right-hand side of the 2% near the stock-engaging end and forces 1t inwardly into stock-engaging position when the arm 7 is swung upwardy into the position shown in Fig. 1. In order to prevent the clip from flexing in the region engaged by thefen'd 8 of the arm 7 the central portion of this part of the clip is pressed inwardl to form

lateral flanges

9 and 10. In ben 'ng the band 1 the upper end is somewhat enlarged so as to make the opening 11 sufliciently large to form a finger opening by which the clip may be grasped.

The clipillustrated in Figs. 1, 5 and 6 comprises an inner band 12 of flexible steel orot'her suitable material which is shaped similarly to the band 1 in Figs. 1 to 3. Extending along the outside of the band 12 is an outer band 13 which is provided with a spur 14 similar to the spur 4 in Figs. 1 to '3. The

bands

12 and 13 are anchored together by means of a struck-up tongue 15 on the inner band extending into an opening 16in the outer band. An opening 17 is provided in the right-hand side of the outer band 13 and on opposite sides of this opening

pivot cars

18 and 19 are struck-up. An arm 20 is pivotally mounted in the

ears

18 and 19, this arm having a projection 21 adapted to engage the right-hand side of the inner band 12. ,The' projection 21 is provided with a central lug 22 adapted to extend into a narrow slot 23 in the band 12 to prevent lateral movement of the righthand side of the band. A fin er-ring 22 may be secured to the upper en (if the clip as shown in Fig. 4, or the opening 23 may be empl yed as the finger-opening as illus trated i Fi 5.

The rli s own in Figs. 7 to 9 is similar to that siown in Figs. 4 to 6 in that it comprises an outer band 24, an inner band 25, a spur 26 on the left-hand side of the outer band and a handle 27 pivotally mounted in cars struck-up from opposite sides of an opening in the right-hand side of the outer band. Instead of attaching a separate finger-ring, as shown in Fig. 4, a loop 34 is struck-up from the outer and Where shown in Figs. 7 and 8. Figs. 7 and 9 also illustrate the fact that the stock-engaging lips of the clip need not he formed as shown in Figs. 1 to 5, but'may be formed by striking-up pointed spurs 35, these spurs pointing upwardly and inwardly so as socurely to engage the stock and revent it from pulling out of the clip. hen providing spurs 35 the ends of the clip band are preferably made substantially parallel throughout the region of the spurs.

To attach our improved clip to a hide or the like, the forefinger is inserted throu h the finger-opening to grasp the clip, and t e jaws are closed over the stock b throwing the actuating arm into close position. Owing to the relative positions of the finger opening and the actuating arm the arm may be actuated by the thumb of the hand supporting the clip, the relationship of the parts being particularly convenient in the embodiments shown in Figs. 1 to 3 where the finger opening extends transversely of the path of the actuating arm. After the clip has been clamped to the stock, the stock may be stretched by pulling the clip and when the stock is sufficiently stretched, the supporting spur is hooked into the wire mesh or other suitable support. Owing to the fact that the attaching spur faces toward the stock-engaging end of the clip, the clip may be quickly attached or de tached to or from the support. To detach the clip from the stock the actuating arm 7 may be swung outwardly by the thumb of the hand supporting the clip inasmuch as the end of the arm projects outwardly in a convenient position when the arm is closed.

What we claim is:

1. A clip comprising relatively movable jaws and a hooked spur adapted without change of form to engage and be disengaged from an opening'in a support there- 2. A clip comprising relatively movable jaws, afinger piece, and a hooked attachmg spur disposed adjacent to said finger piece and adapted without change of form ,to'engage and be disen aged from an openmg in a support there or.

3. A clip comprising relatively movable 1,ese,129

jaws, and means engaging the outside of one of the jaws for forcing the jaws together, the clip having a finger opening ar ranged adjacent to said means so that said means may be operated by one finger when the clip is supported byanother finger of the same hand.

4. A clipcomprising relatively movable jaws, and means for .orcing the jaws together comprising a movable handle, the clip havi a linger opening extending transversely of the path of said handle adjacent thereto so that the handle may be ar-tuated by the thumb when the clip is supported by a finger 0f the same hand.

5. A clip comprising relativel movable jaws, a hooked spur on one si e ada ted without change of form to engage an be disengaged from an opening in a support therefor and means on the other side for (dosing said jaws.

6. A clip comprising relatively movable jaws, a spur on one side for attaching the clip to a support and means including a movable handle on the other side for ol0sing said aws, the clip having a finger opening arranged to permit said handle to be operated by the thumb when the clip is supported by a finger of the same hand.

7. A clip comprising relatively movable jaws having stock-engaging lips, and means including a pivoted handle for forcing said lips together, the (-lip having a finger opening in the rear of said lips and said handle swinging toward said finger opening into closed position. 1

8. A clip comprising relatively movyal ile jaws having stock-engaging lips, and means including a pivoted handle for forcingsaicl lips together, the clip having a finger opening in the rear of said lips and said handle swinging toward said finger opening into closed position, said handle having aprojeeting end adapted to be engaged b the thumb to open said jaws when the c ip is held by a finger of the same hand.
