EVERETT K. LEEFINGWELL AND HARRY B. ELTONHEAD, OF WEST HAVEN, CONNECTICUT.
TUBE-COMPRESSOR.
Specification of Letters Patent.
Eatented May 8, 1906.
To all whom it vnoty concermq Be it known that we, EVERETT K. LEF- FINGWELL and HARRY B. ELTONHEAD, citizens of the United States, residing in West Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Tube-Compressors, of which the following is a specification.
This invention relates to that class of devices employed for compressing a rubber tube to prevent the flow of a fluid through the same. Such clamps or compressors, sometimes called pinchcocks, are employed'in lieu of ordinary cocks on small rubber tubes, such as are connected with douches and the like. Commonly a tube-compressor of this general class comprises two jaws connected integrally at their ends by a broad bowspring having in it an aperture for the passage of the tube which extends lengthwise of the jaws and the jaws are pressed together with a clamping-lever fulcrumed in lugs on one of the jaws, the latter having flat clampingfaces.
The object of the present invention is to provide a tube-compressor wherein the tube extends transversely of the jaws and the jaws have a special conformation designed to produce a perfect closure and prevent any leakage whatever through the tube past the compressor.
In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a perspective view of the device, showing a tube in place and the compressor open. Fig. 2 is a similar view, but showing the jaws closed on the tube. Fig. 3 is a front view of the device as seen in Fig. 2. Fig. 4 is a plan view of the compressor, showing it open. Fig. 5 is a front view of the device as seen in Fig. 1.
The jaws a and b of the compressor are connected at one end by a bow-sprin c, preferably integral with the jaws, and t e compressing-lever d is fulcrumed in lugs e on the jaw a. These lugs or cheeks are relatively large and have in them apertures f for the passage of the rubber tube T, which, as before stated, extends transversely of the jaws.
In order to assure a perfect closure of the tube, each jaw of the compressor has a longitudinal corrugation, which forms a rib g on one jaw and a groove h on the other jaw, whereby when the two jaws are clamped together on the tube the latter is crimped crosswise, as clearly shown in Fig. 3. The camarm (1 on the compressing-lever is recessed at its operative end to engage the rib on the back of the upper j aw.
This compressor or pinch-cock enables the operator or user to utilize the bow-spring c as a ring-handle, either to be engaged by the finger in manipulating the device or for hanging up the tube on a hook.
It is not material that the rib 9 shall be on the jaw a and the groove h in the other jaw. The rib may as well be on the jaw b.
The compressing-lever 61 being of elbowshape and made from sheet metal and having work to perform which puts it under considerable strain at the angle, this lever is corrugated over the angle and along its arm in order to give it additional strength and rigidity.
Having thus described our invention, we claim A tube-compressor having two jaws connected by a spring, said jaws being provided with longitudinal correspondingly-shaped corrugations, upright lugs on one of said jaws and a compressing-lever fulcrumed in said lugs said lugs being provided with apertures adapted to hold the tube to be compressed between the jaws and in a position transverse thereto. v
In witness whereof we have hereunto signed our names, this 28th day of March, 1905, in the presence of two subscribing witnesses.
