Specification of Letters Patent.

Patented Nov. 28, 191 1.

Application filed .fiine 29 1910. Serial No. 569,563.

To all whom it may concern:

Be it known that we, FRANCIS J. WV. MAGU'IRE and 'lnnornsuns LUGIER, citizens of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful improvements in Clamps, of which the following is a specification.

Our invention relates to clamping devices for holding flags and attaching them to automobiles for decorations on parades, but which may be used forother purposes.

One object of the invention is to provide an improved clamping means to engage a plurality of fla stalls or rods, the construction being sue that different sized stafl's me be securely held.

nother object is to provide in connection with the flag holding means an improved double clamping device capable of engaging various supports and holding the flags in different ositions.

With t ese objects in view the invention consists in the novel features and combinations of parts hereinafter described and claimed, and illustrated in the accompanying drawings in which:

igure 1 is a front elevation with lower portion broken away. Fig. 2 is a side elevation partly in section. Fig. '3 is an elevation of clampin member.

Our improve means for holding one or more flag stafl's or other articles, comprises two clampingmembers A, A in the form of plates one of which carries the other and is itself carried by the attaching or supporting means. These plates have formed in their inner faces opposing seats or grooves a to receive the flag staffs; and in order to revent the possibility of the staffs shifting ongitudinally when clamped in the seats a, the latter have molded in them spiral ribs a. The two clamp plates may, of course, be of any sha e and adapted to support a plurality of age in any desired arrangement.

To draw the two clamp plates A, A together and cause them to effectively bind different sized stafls, we provide screws B and opposing inclines C whereby when the two plates are drawn together they will be caused to move dia onally or angularly with respect to each ot er and will hence more eflectively grip the flag staffs. The inclines C are here shown as being on the o posing faces of two pairs of lugs a tonne on the inner edges of the clamp plates although said inclines may be otherwise formed and located. The screws B are preferably in the form of studs fixed at one end in the removable plate A and adapted to project through slots by in the plate A and carry thumb-nuts b on their threaded ends. The slots b are so located that the screw studs may shift in them when the opposin inclined faces C slide on each other in tightening the thumb-nuts.

The attaching clamp consists of two members] D, D formed at their ends with jaws d, d, and d d andhaving their intermediuteportions united by a screw E which serves to tighten both pairs of jaws simultaneously. The jaws cl, d, are claw-like and form opposing sockets for the reception of a ball which is connected by a s'temd to the center of the clamp late A. These parts, it will be observed, orm a ball and socket joint between the attaching 'clamp and the flag holding clamp whereby the latter may be held at various angles.

The jaws d, d are constructed for engagement with objects of different shapes. To permit them to engage a lamp bracket, fender iron or similar part of an automobile or other vehicle, their inner portions have 'opposing'transverse grooves or seats d, and to permit said jaws to engage window frames, door jambs and other places where it may be desirable to hang a flag or other article, the end portions of the opposing faces of the jaws are made flat. These flat faces may be roughened as at d" if desired and they are also formed with transverse grooves cl adapted to receive anail either before or after it is driven into a support. The fiat end portions of the two jaws (1', rl may be formed with screw-holes d whereby the holder may be screwed to a support which cannot be engaged by the jaws.

The screw E passes through transverse openings in the two clamp members and has its head fixed against rotation in the member D as shown at e while its threaded end carries a, thumb nut 13. A spring F is arranged on the screw between the clamp member and is adapted to keep the parts of the clamp in position and spread the two jaws cl, (1 when the nut c is loosened. This spring is formed from a strip of resilient metal bent upon itself at f to provide spaced arms having their intermgdiate porlit) lions apertured to receive the screw F. The extremities of the two arms of the spring are bent outwardly to provide fingers f which enter recesse 2 in the inner faces of the memlwrs I), I and thereby prevent the Spring 'rom turning on the screw as well as cause the jaws at, d to spread apart.

In use, the flag stalls are securely held between thrrlamp plates A, A. and the latter are held in the desired position by means of the attaching clamp which is double ed ting since the tightening of the nut 0' causes the claw-jaws (l, (l to grip and hold the ball in adjusted position and also causes thejawsd", d to firmly grip a suitable support. Owing to the peculiar-shape of the last named jaws, the attaching '0 amp may be applied to different parts of an automobile or other ob ject and in difl'erent positions, while the ball and socket. joint enables the flag holding clamp to be held in ditterent positions with respect to the attaching clamp. The peculiar slot and screw-pin connection between the clamp plates of the Hag holder and the formation of the opposing inclined surfaces on said plates, enable at least tlireeditt'erent sized flag" staffs to be effectively clamped in the device, thereby greatly increasing its range of usefulness.

\Ve claim 1. The combination of a ball provided with stem carrying a clamp, opposing clamp members to receive a. plurality of articlcs between them. said members having seats to receive the articles. and also having, a slot and pin connection, opposing inclines on thetwo membrrs to cause them to move in an angular or diagonal direction when they are drawn toward each other, means on said pins for drawing the two members to gethcr, a second pair of opposing clamp members having at one end socket jaws to engage the ball, and at the other end object engaging jaws, the intermediate portions of said members having recesses in their inner faces, a transverse screw arranged in the members between their ends for drawing them together and simultaneously tightening both pairs of jaws, and a spring bent upon itself to provide spaced arms arranged between said members and having openings to receive said screw and bent extremities forming fingers to enter the recess in the inner faces of said members.

2. The combination of oiposing clamp members to receive a plum ity of articles between them, said members having seats trreeeive the articles, and also having a slot and pin connection, opposing inclines on the two l'HQl'HlXBIS to cause them to move in an angular or diagonal direction when they are drawn toward each other, and means on said pins for (.lli, ng the two members together.

The combination of a ball provided. with a stem marrying a clamp, opposing clamp members having, at one end socket jaws to engage the ball; and at the other end object engaging jaws, the intermediate per tions of said members having recesses in their inner tacos, means connecting the intcrmediatc portions of the members to draw them together and cause both pairs of jaws to be simultaneously tightened, and a sprin strip bent upon itself to provide spaced arm arranged between said members and having openings to re eive said cornice-ting means and bent extremities forming fingers to enter the recesses in the inner faces of said members, and he inner face of: said jaws having ti'iin-wcrslgroo es of varying t. The -mubma.ion of a ball provided with a stem carrying a clamp, opposing clamp liiclnlicrs listing at one end socket jaws to engage the ball and at the other end object engaging jaws, the intermediate por tions of .5 id members having releases in th ir inner fa -c--. a lIi'.ii: J(-!f-1& scri'nv arrange-ll in ilft. members etween their ends for drawing them together and simultously tiglitcning' both pairs: of jaws, and a spring strip hunt upon. its-ell? to provide spaced flffih arranged between said members and having openings to receive said screw and bent extremities forming fingers to entor therecesses in the inner'faces of said members, for the purposes set forth.

In testimonfv whereof we afiix our signatures in presence of two vitnesses.
