Application `October 19, 1942, Serial No. 462,652

(Gl. A185-'5f) l This 'invenn'qn 'has to do with clamps and, more particularly, rtf-relates to resilient lamps ffor clamping sheets 'together along their s'iie edges.

yIt 4is among the objects ofthe invention to `Aprovide a clamp oi this character which may lbe easily .andrapidly operated, which yis eritrenely durable, which is economical of manufacture and which embodies efiectiv'e safety features.

For example, ywelshallnow describe apresentfl'y 'preferred adaptation df the invention, a1-

though the details resorted 'to in the following `desciip'tio' are t0 be understood merely aS li'd's to a clear understanding o'i the invention since Within its broader scope as dened by the ap pended claims it will Fbef'zoirie obvious that the ina cylindric body having an end wall 5 provided with a central opening 1. Adjacent the top end of the body there is a reduced diameter portion B to receive an applying tool, not shown, and providing an annular undercut shoulder 9 for engagement with the applying tool whereby to hold the body against longitudinal movement as will be hereinafter explained.

IThe bottom end portion l of the body is of reduced diameter to facilitate the mounting thereon of an inner jawl whose outer face ld provides one of the work engaging surfaces. It will be understood, of course, that jaw I may be formed integral with body 5 if preferred ,al1- though we find the structuredescribed to be advatageousfrom a manuacturing standpoint. A An operating plunger is reciprocally mounted longitudinally in the body for protraction and retraction through the opening 1 in the body end wall 6. A coil spring 2 l, seating at its inner end against the inner surface of end wall 5 and seating at its outer endv against the headed end'iZiZ of the plunger, normally urges the plungero into retracted position. l

An outer jaw is threadedly or otherwise suitably secured on the opposite end of the plunger 2i), the inner surface 25a of this jaw providin'g a work engaging surface opposed `to the work engaging surface 15a of the other (jaw.

uOn the back ,portion ofthe ja'w 25 we secure, as by spot welding 'or in any vother suitable manner, an elongated .plate 3D which .projects longitudinally along the 4jaw t5 and the 'body eirterioi' "and is .provided with a `longitudinal slot V3l. A pin 33, secured at yits inner end in a hole inthe Ljaw l5, projects into the slot "3l, s This pin and v'slot arrangement serves to prevent jaw vfroin rotating with vrespect to the body and out of register with jaw Af5 but .permits 'relative longitudinal movement between 'those members.

To `lighten the device the "jaws i5, 25 are holldwed `a`t (i6,

In operation, the clamp device is placed in an applying tool, not shown, a tool suitable for this purpose being shown in United States Letters Patent No. 2,296,439, dated September 22, 1942. By means of this tool, the body 5 is held While the plunger 28 is pushed inwardly of the body against the pressure of the spring 2|. Such protraction of the plunger separates the Work engaging surfaces |5a, 25a of the jaws, in which position the jaws may be applied over the side edges of the work to be clamped, the work being here vshown as two superposed sheets S, S (Fig. 2) Release of the protracting pressure on plunger 20 permits the spring 2| to urge the jaw 25 towards jaw I5 to clamp the work between the work engaging surface of those jaws as shown in Fig. 2.

We claim:

l. A device adapted to clampingly engage the side edges of work to be clamped, comprising a body, a laterally projecting inner jaw carried by the lower end of the body, a plunger reciprocally mounted in the body for protraction and retraction through the lower end of the body, a spring normally urging the plunger into retracted position, and an outer jaw secured to and projecting laterally from the lower end of the plunger in register with the inner jaw, said jaws being operable by virtue of retraction of the plunger to resiliently clamp the work therebetween. l

2. A device adapted to clampingly engage the side edges of Work to be clamped, comprising a body, a laterally projecting inner jaw carried by the lower end of the body, a plunger reciprocally mounted in the body for protraction and retraction through the lower end of the body, a spring normally urging the plunger into retracted position, an outer jaw secured to and projecting laterally from the lower end of the plunger in register with the inner jaw, said jaws being operable by virtue of retraction of the plunger to resiliently clamp the work therebetween, and means preventing rotative movement of one of the jaws with respect to the other.

3. A device adapted to clampingly engage the side edges of work to be clamped comprising a body, a laterally projecting inner jaw carried by the lower end of the body, a plunger reciprocally mounted in the body for protraction and retraction through the lower end of the body, a spring normally urging the plunger into retracted position, an outer jaw secured to and projecting laterally from the lower end of the plunger in register with the inner jaw, said jaws being operable by virtue of retraction of the plunger to resiliently clamp the work therebetween, and means preventing rotative movement of one of the jaws with respect to the other, said last-l through the end wall, an inner work engaging vjaw carried by and projecting laterally from the side of the lower end portion of the body, a 'plunger reciprocally mounted in the body for .protraction and retraction through said opening,

an outer work engaging jaw carried by and pro jecting laterally from the lower end of the plunger in register with the inner jaw, said jaws being movable towards each other upon retraction of the plunger, and a coil spring mounted in the body around the plunger, said spring seating at one end against the body end wall and seating at its other end against an end portion of the plunger whereby to normally urge the jaws towards each other and into clamping engagement with the work.

5. A device adapted to clampingly engage the side edges of work to be clamped, comprising a cylindric body having an end wall, an opening through the end wall, an inner work engaging jaw carried by and projecting laterally from the side of the lower end portion of the body, a plunger reciprocally mounted in the body for protraction and retraction through said opening. an outer work engaging jaw carried by and projecting laterally from the lower end of the plunger in register with the inner jaw, said jaws being movable towards each other upon retraction of the plunger, a coil spring mounted in the b ody around the plunger, said spring seating at one end against the body end wall and seating at its other end against an end portion of the plunger whereby to normally urge the jaws towards each other and into clamping engagement with the work, and means preventing rotative movement of one of the jaws with respect to the other, said means including an elongated plate secured to the rear surface of the lower jaw and projecting along the outer surface of the inner jaw, a longitudinal slot in the plate, and a pin secured in the inner jaw, said pin projecting into and being slidable along the slot.
