Application December 11, 1935, Serial No. 53,841
This invention relates to clips, clamps, grips and like devices for engaging and Supporting articles entered between their jaws.
An object of the invention is to provide a clamp having a pair of gripping jaws united by a spring at the end of the jaw carrying arms whereby they are maintained in register irrespective of their distance apart.
A further feature is in the provision of a jaw closing device adapted to cause the jaws to securely grip an entered article of any thickness within the scope of the device.
Another purpose is to produce a clamp symmetrical in shape, of pleasing appearance, adapted for many purposes and inexpensive to construct.
These meritorious objects are accomplished by the novel design, construction and combination of few and simple parts, as hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which:
Figure 1 is a side elevational view of an embodiment of the invention in substantially closed positions in full lines and also in open position in broken lines.
Figure 2 is a view taken in a plane at a right angle to Figure 1.
Figure 3 is a transverse sectional view taken on line 3--3 of Figure 1.
Figure 4 is a longitudinal sectional view taken on line 44 of Figure 1.
Figure 5 is a side view similar to Figure 2 showing the clamp as bracket supported and an article engaged by its jaws.
Referringin greater detail to the drawing, a pair of flat jaws l0l| are formed at the outer end of semi-circular loops i2l3 which blend into tapered arms l4--l5 integrally connected at their opposite ends by a spring eye 16.
Each longitudinal side edge 01'. these members are provided with flanges l8-I9; the flanges on the arms I 4-45 having a plurality of teeth 20-2l and intermediate the flanges the arms contain longitudinal slots 22-23.
The normal position of the jaws l0-Il is distended, due to the effects of the spring I6; they are brought toward each other by a slider or runner formed from flat sheet metal to present a pair of opposed crescent shaped handles 25.
The inner adjacent edges 26 of the handles may be bevelled or otherwise shaped to form teeth suited to engage the teeth 20-2] of the arm flanges, and the handlesare coupled by a connecting bar 2'! slidable in the slots 2223.
When the runner engages the teeth 20--2l at the narrower ends of the arms, close to the spring I6, the jaws present their largest opening and, as the runner is moved towards the jaws, they are caused to approach one another, gripping firmly any article entered therebetween.
This condition is clearly indicated in Figure 5 and in addition, a stud 30 is shown as supported by the arms 3| of a bracket 32 attached to any convenient object.
g In this disposition the clamp can swivel on the stud constituting an eilective and convenient means for the temporary disposal of articles.
Although the foregoing is descriptive of the best known embodiment of the invention, it will be manifest that changes not involving invention may be made without departing from the claims hereto appended.
Having thus described the invention, what is claimed as new and sought to secure by Letters Patent, is:
1. A clamp comprising a pair of spaced arms integrally connected by a spring at one end and having arcuate loops at their opposite ends, a pair of jaws integral with the outer ends of said loops, outstanding flanges on the edges of said arms,
said flanges being corrugated to present a pluments on the ends of said slider, and means on I the adjacent edges of said handle elements adapted to engage the teeth on said flanges.
2. A clamp comprising a pair of spaced identically duplicate arms arranged in opposed relation integrally connected by a spring at one end and having arcuate loops at their opposite ends, a pair of flat jaws integral with the outer ends of said loops, outstanding flanges on the edges of said arms, the flanges on said arms being corrugated to present a plurality of teeth, said arms being slotted longitudinally, a slider adapted to move in the mentioned slots from end to end of the arms, handle elements on the ends of said slider, bevelled edges on said handle elements adapted to engage the teeth on said flanges, and a bracket having a stud on which said spring is rotatably mounted.
