(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for Government for governmental purposes, without the payment to me of any royalty thereon.

My invention relates to improvements in handle clamping devices and has for its object to provide a s'mple, inexpensive, and conveniently applied handle device adapted to be clamped on to the mouth of flexible containers, gasoline bags, and the like to seal the same and provide a convenient handle therefor.

The device is also adaptable in connection with handling heavy tarpaulins, tents, airplane Wing covers, parachute shroud tape lines, or any fabric or flexible member where it is desired to apply a manipulating or securing handle thereto.

An object of my invention is the provision of a detachable handle-like clamping member which may be easily and quickly clamped on to or removed from a flexible article such as a fabric container or gasoline bag together with a positive keeper or locking means to hold the device in clamping position in which the keeper or looking means comprises the handle member for carrying or manipulating the article being engaged by the device.

A further object is the provision of a handle clamping device having spaced pairs of intermediately pivoted adjacent clamping members provided with fabric clamping means at one end and diverging operating arms at the other end, and a keeper or locking means extending across the device between the spaced pairs of adjacent clamping members for simultaneously moving the clamping arms to a clamping position, locking the arms in the clamping position, and constituting a handle member for the device and for the fabric or article being clamped and handled thereby.

Other objects of the invention will be apparent from the following description, in which like reference characters refer to like parts in the several figures of the drawing.

Fig. 1 is a perspective view of my improved handle clamp showing the keeper or looking handle plate in released position adjacent to the pivoted center of the clamping frames.

Fig. 2 is a vertical sectional view taken approximately on the line 2-2 of Fig. 1, and showing my invention in clamped position in full lines, in engagement with a flexible article, and disclosing the combined handle and keeper plate in released position in phantom.

Referring particularly to'Fig. 1, my invention posed clamping arm portions El and ranged to move in between the spaced adjacent comprises a pair of crossed rectangular clamping frames i and 2 formed of wire or other rigid material and flattened intermediate their ends as at 3 and i to provide enlarged portions for the pivotal connections 5 at the crossing point of the frames. The outer frame I comprises spaced side bar members 6 and l and spaced end bar members 5 and 9, as seen in the drawing. A cross or snubbing bar member i9 is secured across the outer frame 8 between the side bars 6 and l in parallel relation to and spaced from the end or snubbing bar member 8.

The inner rectangular frame 2 is formed with side bar members H and i2 and disposed adjacent to the side bar members 6 and l of the outer rectangular frame member i. This frame 2 also includes a lower clamping or snubbing bar l3 formed integrally with the side bars it] and ii and the upper cross bar id, The side bars ill and ii are bent laterally intermediate the lower bar i3 and pivots 5, as indicated at E5 and E3 in the drawing to form a pair of angular disiil arside bars 6 and l with the snubbing bar it disposed parallel to and between the cross or snubbing bars 8 and Ill of the frame l.

Sleeve members i9 and 29 are preferably loosely mounted on the bars 9 and M of the upper end frame members i and 2 to provide for easier handling of the device.

The upper or operating portions of the adjacent side bars 6, H and l, l2 diverge outwardly from the pivots 5 and carry a keeper or locking handle plate 2! which is flanged along its opposite longitudinal edges as indicated at 22 to reinforce the same and prevent the presentation of sharp or cutting side edges likely to injure the hand of a person using the device when carrying or handling heavy articles or loads.

The locking handle plate is formed with apertures 23 at opposite ends thereof to receive the diverging upper portions of the spaced pairs of adjacent side bars 6, H and 1, i2 of the frames l and 2. When the handle or keeper plate 2! is disposed near the pivots 5 as seen in Fig. 1 and in phantom in Fig. 2, the distance between the bars 6, H and E, E2 is considerably less at this point than the openings through the apertures in the plate, which permits the clamping portion to be opened, as seen in the phantom in the drawing, to receive an article to be clamped and handled by the device.

In the use of the device, the mouth of a fabric gasoline bag or other flexible article having a.

somewhat sheet-like character is inserted between the cross or snubbing bars 8 and It, brought around the bar In and back along itself to a point below the bar 8. When the diverging upper portions of the spaced pairs of bars 6, H and I, I2 are brought toward each other and the keeper or handle plate is moved outwardly from its position adjacent the pivots t, the ends of the apertures 23 engage the diverging portions aforesaid, moving these same toward each other. This causes the snubbing cross bar it of the frame 2 to pass through between the two snubbing cross bars 8 and it on the frame i, carrying the intermediate portion of the fabric or flexible article being clamped with it to the position shown in full lines in Fig. 2 and thus producing an efficient clamping effect or snubbing action on the article being engaged by the device.

The keeper plate 2! extends across the device between the adjacent pairs of side bars 8, i I and i, l2 and functions as a locking member, preventing the opening of the clamping end portion of the device, and also constitutes a handle member which is readily gripped by the operator, if the article being engaged is to be carried, or it may be used to pass a lashing through, if it be so desired.

The relatively wide spacing of the pairs of adjacent side members of the rectangular frames permits comparatively wide articles to be engaged, while the comparatively long snubbing or clamping cross bars between the frames provide a large gripping area which reduces the tendency for the handle clamp to tear light or easily injured fabrics, bags, covers, and the like. The handle member 22 extending between the comparatively widely spaced sides of the frames also presents a comparatively large supporting area making it possible to more readily carry comparatively heavy loads by the device with greater comfort.

Although a single preferred embodiment ofthe invention is shown, it is to be understood that the invention may take various forms, and is to be limited only by the appended claims.

I claim:

1. In a handle clamp, a pair of rectangular frames pivoted to each other intermediate their ends and at opposite sides, each frame having a clamping portion at one end and an operating portion adjacent the other end, said frames including spaced pairs of adjacent side bars connecting the said clamping and operating por tions of the frames, and a clamping and locking handle plate member slidably disposed on the said spaced pairs of adjacent side bars and extending between the same to engage the said adjacent side bars at opposite sides of the frames and hold the same in clamping position, said plate including a handle portion intermediate 'said pairs of adjacent side bar portions.
