PETER SAMUEL GRAVES, OF PORT HENRY, NEW YORK.
EXTENSION-CLAMP.
SPECIFICATION forming part of Letters Patent No. 386,065, dated July 10, 1888.
(No model.)
To all whom it may concern:
Be it known that I PETER SAMUEL GRAVES, a citizen of the United States, and a resident of Port Henry, in the county of Essex and State of New York, have invented certain new and useful Improvements in Extension Clamps; and I do declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure 1 of the drawings is a representation of this invention and is a side view. Fig. 2 is a vertical section taken where the broken line :10 a: is marked on Fig. 1. Fig. 3is a plan view of the inner side of one of the clamps. Figs. 4 and 5 are details, the first being shown in perspective, with a part broken away, and the second a cross-section. Fig. 6 shows a modification.
The invention relates to improvements in extension-clamps for flasks; and it consists in the construction and novel combination of parts, as hereinafter set forth.
Referring to the drawings, A designates the two claiupbars having their outer ends turned outward at right angles,B,to engage the upper and lower edges of the flask. Wrought-iron keeperstraps G are integral with the clampbars near the inner end. The keeper-straps are turned upward and over the edge ofthe clamp bars, as at a; or the ends may be perforated, as at a, and the bolt I) inserted above the outer face of the bars. The straps should be sufficiently loose to allow adjustment of the two clampbars. On their inner faces the bars A arelongitudinally recessed, as shown at D, and transverse raek-teeth b are provided at one side of the recess, the detent side, 0, of the teeth standing toward the angle 13. A short rack, E, is cast upstanding from the inner end of each clamp'bar, and is adapted to slide within the recess of the adjacent bar and engage the rackteeth of said recess. The racksE are somewhat narrower than the recesses, so that by pulling the two bars laterally in opposite directions the rack E is disengaged from the teeth in the recesses, thus allowing the clamps to be opened. Aseries of slot openings, f, in the clamp-bars are designed for the entrance of a lever, F, by means of which the clamp is retracted upon the flask. As will be observed in the drawings, the transverse portions 9 between the slot-openings of one clamp-bar act as fulcrums for the lever as its end engages the transverse portion 9 of the opposite bar.
Having described my invention, what I claim 1s 1. In an extension clamp, the two bars, each having an end turned outwardly, the short rack,and the recess provided with rack-teeth, substantially as specified.
2. The two clamp-bars, each having the outwardly-turned end, the keeper-straps, the recess,the rack-teeth, and the short rack, substantially as specified.
3. The two clamp-bars, each having an end turned outwardly at right angles, the recess provided with the rack-teeth, the short rack, the slot-openings, and the keeper straps, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
PETER SAMUEL GRAVES.
