The invention herein relates;- to improve-f ments in clamping attachments for revolvers and pistols. and particularly to a novel clamp-- ing attachment having companion jaws, one

movable and the other immovable and means to lock said jaws. i g a An object of the inventionis to provide a clamping attachment for revolvers and guns with improved means for releasably securing the movable jaw into locking engagement withits companion jaw so that an object may be positioned on the frame of a revolver or Another object of the invention is to provide an improved clampingattachment for revolvers and pistols, having a. fixed jaw and a manually operable latohmembercooperating with a movable opposed jaw for locking engagement of the twojaws in clamping position. k I

Another object ofthe invention is to provide a simple, j durable, improved clamping attachment of the character referred to herein, which may be inexpensively manufactured and easily mounted upon a revolver or other form of firearm to position a flashlight or other object thereon securely and releas- I i r (d ther objects of the invention as will a pear hereinafter as the descriptionIprocee s, will be more readily understood from a perusal of the followingspecifica-tion, refer ence being had to the accompanying draw in'g, in which: p Figure 1 is a side elevation'of a revolver or gun showing my improved clamping attachment mounted thereon. i

Fig. 2 is a transverse section of line 22 thereof. r

Fig. 3 is a perspective view of the improved clamping "attachment disassembled into its 'respectivejparts, herein shown in bracket.

The improved clamping attachment vfor revolvers and guns shown in the accompany ing drawing preferably 1 oomprises'a substantial'ly rectangular mounting plate, 4;, having a plurality of perforations 8, therein, suitable. for reception of bolts or rivets for securably fastening the plate toa flashlight 9, or other object which isydesired to be mounted on the revolver (or gun) '10, for use therewith.. "Such mounting plate is provided with a vertically integral downwardly extending jaw 11, along the greater central margin of one of its sides, said jaw being bent its entire length inwardly and parallel to the underside of the top ofsaid mounting plate, as at 12 to provide for such jaw a secure grip along the raised longitudinal strip 13, of the upper portion of the revolver frame when inueo operative engagement therewith.

Themounting plate is adapted to be fas t ened' substantially flush with [the underside of the flashlight or other object desired to be mounted thereon for use with the 're- I volver. v The fixed jaw is integral with the greater central margin of one side of the mounting plate. The'other side of the mounting plate is provided with an opposed integrally fixed downwardly extending retaining wall 14, parallel to the fixed jaw and terminating at a point above the upper plane of the inward-:

ly turned grip of the fixed jaw, a distance equal to the normal thicknessof the raised strip. To form theinwardly turnedgripping portion ofthisretaining wall 14, there is provided a movable jaw 15,having parallel :

open sleeves

16 and 17, cylindrioally mounted on the rock-shaft'18, which shaft is freely journaledin the integral housing 19, (Fig. 1) of the mounting plate 5.

amMEsnrooLE, or CHICAGO, rumors member is movably and eccentrically mounted on the integral cross-bar 22 of the housing arms and spans the recess therebetween and is adapted to be manually moved about such cross-bar as an axis, downwardly to lock the movable jaw into clamping arrangement with the fixed jaw and upwardly to release the movable jaw outwardly and into released relationship with such fixed j aw Such latch member is provided with an integral handle 23. The eccentric mounting and cam-shape of such latch member securely holds the movable jaw into locking engagement with the.

companion jaw by reason of the abutment of the vertical face 24: of such latch member against the outside of the movable aw when such latch member is directly perpendicular to its horizontal axis and unlocks the movable jaw when in any other position. There is also provided an arcuately shaped integral rock-shaft handle or lever 25, extending 011t- Wardly of the shaft to oscillate manuallythe movable jaw to open or remove it from the opposed jaw to remove the clamping device from the revolver when ClGSlIGd, Such. han-' dle is secured integrally to the movable jaw intermediate-the sleeves of the same in the channel providedbetween such sleeves.

'A rubber or other resilient pad 26, inserted in the channel formed by the fixed jaw and the retaining wall provides a suitable rest for the mounting'plate and the frame of the gun and prevents direct contact between the trame and the mounted object.

In operation when it is desired to'attach a flashlight or other object having a fiat undersurface to the top of the revolver or gun, it may be securely riveted or bolted to the top of the mounting plate. The clamping device is then locked and unlocked by the manual operation of the latch member and the integral arcuate handle. When the latch member is perpendicular anddownward of the cross-bar upon which it turns, the jaws are locked. lVhen the latch member is p0- sitioned otherwise, the jaws are unlocked. The eccei'itricity of the shape of the latch member provides a secure and releasable lock. Thus a clamping attachment for obj ects is afforded which in no way changes the normal use of the fire-arm.

Although anexemplary *form of the device has been shown in the accompanying drawing and described in detail in the foregoing specification, -it is to be understood that the clamping attachment may embody various modifications in detail structure without departing from the spirit of the ap pended claims.

. I claim: I

1. A device of the character described,

7 comprising in combination, a mounting plate,

adownwardly vertically extending integral jaw at the greater central margin of one side of said mounting plate, a retaining wall extending parallel'and vertically downwardly on the opposite of said mounting plate, at thegreater central margin thereof, outwardly extending parallel end arms in said wall, a rock-shaft journaled in said end arms, and a companion jaw, oscillatably and cylindrically'mounted on-said rock-shaft and adapted to co-operate with said fixed jaw to form a lock, and a downwardly and upwardly movable latch member, mounted upon a central bar, transverse parallel outside closure arms in the retaining wall, said latch member adaptedto lock said pair of jaws releasably together.

2'. A device of the character described, comprising a mounting plate, a downwardly vertically extending integral jaw at the greater central margin of one side of said mounting plate, a retalning wall fixedly secured to the opposed greater central margin of said 1nounting plate and parallel to said fixed jaw, a comfpanion jaw movably mounted upon a sha V t journaled in parallel opposed outwardly extending transverse end arms integral with said retaining wall, and a pair of arms extending integrally from said transverse arms, inwardly and parallel to the retaining wall, at a right angle, to the end arms, said inward arms having a recess between the meeting, ends thereof and a cross-bar spanning said recess, said cross-bar. having mounted thereon an eccentrically downwardly and upwardly movable latch member provided with a cam-shaped periphery for looking said pair of jaws when said latch member is vertical and downward of its horizontal axis. V

3. A device of the character described, comprising a mounting plate, a downwardly vertically extending integral jaw at' the greatercentral margin of one side of said mounting plate, a retaining wall fixedly secured to the opposed greater central margin of the mounting plate, and parallel to said integral jaw, parallel opposed transverse end arms integral with said retaining wall, inwardly turned longitudinal arms integral with said end arms, and parallel to said retaining wall, arecess between the meeting a point of said longitudinal arms, a movable lower cross-bar spanninga recess between the longitudinal arms of said retaining wall, for

moving downward to lock j said pair of jaws and upward to unlock them, and an arcuately shaped outwardly extending rocking handle disposed intermediate a recess in the sleeves of the movable jaw for manual oscillation and locking of said movable jaw to 0 n'andj close the same from and with the fix j awry:
