CLAMP.
l Specification of Letters Patent. Patnted Sept 27 11921.
Application led March 15, 1920, Serial No. 365,938. Renewed May 11, 1921. Serial No. 468,728.
To all whom 'it may concern j, y
Be it known that I, FREDERICK HACH- MANN, a citizen of the United States yof America, av resident of the city of St. Louis, in the FtateV of Missouri, have inventedY certain new and useful Improvements 1n Clamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification. y
This invention relates to improvements In clamps, one of the objects being to produce a strong and simple clamp having a firm thrust-receiving bearing v,for a clamping screw. More specifically stated, the preferred form of vthe invention comprises a novel combination of elements whereby a simple thrust-receiving member is securely anchored in a yoke, to which the stresses are transmitted from the clamping screw. This thrust-receiving member is preferably a tube threaded to receive the clamping screw and preferably interlocked with the yoke, so as to effectively withstand the stresses to which it is subjected.
Figure I is a side eleva-tion, partly in section, illustrating a clamp embodying the features of this invention.
Fig. II is a front elevation of the clamp.
Fig. III is a vertical Section illustrating the thrust-receiving sleeve anchored in the oke. y Fig. IV is a horizontal section taken approximately on the line IIT-IV, Fig. III, the pro'ections at the lower end of the sleeve being sliown in elevation.
Fig. V is a section on line V-V, Fig. III;
To illustrate the invention, I have shown a yoke comprising oppositely disposed thrust arms A and B, and a connecting member C uniting said arms. The elements oi this yoke include a continuous web having a horizontal upper member 1, a horizontal lower member 2 and a vertical member 3. Flanges 4 extend from the side margins of the continuous web, said flanges being combined withthe web to form a continuous yoke, channel shaped in cross section.
At the end of thrust arm A, the web 2 is extended and turned downwardly and backwardly between the lianges 4, as indicated at 2LL and 2b, the downturned member 2a being between end margins of the flanges 4 and thel member 2b being between the lower margms of said flanges. Apertures 5 are formed In said lower margins, and the webr member 2b is provided with lateral projections 6 which extend into said apertures. The extended end portion 2b of the web is thus interlocked with and securely anchored in the flanges 4.
-A threaded thrust-receiving sleeve D is arranged between the iiangesy 4 of the lower arm A and also between the horizontal web- 2 and the end portion of its extension 2b. The bottom face of theV sleeve or tube D is seated upon the end portion 2b of the web, while the upper portion of said sleeve` is seated in a circular opening in the web2. The upper end of thrust-receiving sleeve D is turned outwardly to form a ange 7 seated upon the faceof the web member 2. At its lower end, the sleeve D is provided with lateral projections 8 extending into the apertures 5 and seated upon the projections 6 ofthe web member 2b.
The yoke is preferably made of thin pressed metal, and thesleeve D is inserted into arm A while itsilanges 4 are separated a distance great enough to receive the projections 6 and 8. Thereafter, these flanges 4 are forced toward each other for the purpose of locating the projections 6 and 8 in the apertures 5.
9 designates a clamping screw mounted in the threaded sleeve D and having a head 10 at its lower end and a seat 11 at its upper end. When the clamp is in service, the screw 9 is tightened and the sleeve D is subjected to a thrust in a downward direction from the position shown by Figs. I and III. Owing to the manner in which the sleeve D is combined with other elements of the clamp, the thrusts tending to displace the sleeve are firmly opposed by the anchored web member 2b on which the bottom of the sleeve is seated, and also by the flanges 4 Awith which the sleeve projections 8 are setions 2, and 2b, which cooperate with web 2 and flanges t to form a housing for the thrust-receiving sleeve.
I claim:
l. A clamp comprising a yoke havingl oppositely disposed thrust-receiving arms, one
of said arms being in the form of a channel having a web and marginal flanges extending therefrom, a threaded thrust-receiving tube between said flanges, said web having an extended end portion turned downwardly and backwardly to form a seat for one end of said thrust-receiving tube, and a clampf ing screw mounted in said thrust-receiving tube.
2. A clamp comprising a yoke having oppositely disposed thrust-receiving arms, one of said arms .being in the form of a channel having a web and marginal flanges extending therefrom, a threaded thrust-receiving tube arranged between said flanges and having its upper portion seated in said web, said web being extended downwardly and backwardly between said flanges to form a seat for the lower end of said tube, the extended portion of said web being interlocked with and secured to said flanges, and a clamping screw mounted in said thrust-receiving tube.
3. A clamp comprising a yoke having oppositely disposed thrust-receiving arms, said yoke consisting of ai web and side flanges extending therefrom to form a channel lshape in cross section, said web having an extended portion turned downwardly and backwardly between the margins of' the flanges at the outer end of one of said arms, said flanges being provided with apertures and the end of said extended portion of the web being provided with lateral projections anchored in lsaid apertures, a threaded sleeve arranged'between the apertured flanges and having its upper end turned outwardly and seated on the face of the web, the lower end of said sleeve. being seated on the extended end portion of said web and provided with lateral projections anchored in said apen tures, and a 'clamping screw mounted in said threaded sleeve.
Intestimony that I claim the foregoing I hereunto affix my signature,
FREDERICK HACHMANN.
