SWIVEL.

7 To all whom it may concern:

Be it known that 1, AUGUST J. FIsHnR, a Woodsman, citizen of the United States, residing at Camas, in the county of Clarke and State of Washington, have invented certain new and useful Improvements in Swivels, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in swivels and it is an object of the invention to provide a device of this general character with novel and improved means whereby the relative rotatable members may operate with a minimum of frictional resistance.

It is also an object of the invention to provide a device of this general character comprising two relatively rotatable members and whereby said members comprise a novel and improved construction whereby the same may be readily-and conveniently assembled.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved swivel wherein certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings wherein,

Figure 1 is a view partly in section and partly in elevation of a swivel constructed in accordance with an embodiment of my invention;

Fig. 2 is also a view partly in elevation and partly in section of my swivel as herein embodied but with one of the members in a difierent position;

Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1;

Fig. 4 is a view partly in section and partly in elevation illustrating a swivel constructed a further embodiment of my invention.

Fig. 5 is a fragmentary view partly in top plan and partly in section illustrating in detail the opening in the plate as embodied in the structure disclosed in Fig. &.

As particularly illustrated in Figs. 1 to 3 Specification of Letters Patent.

Application fi1ed August 22, 1917.

Serial No. 187,680.

of the accompanying drawings 1 denotes a plate affording a restricted opening 2 having the wall thereof rounded as indicated at 3. Extending laterally from a face of the member '1 are the elongated arms 4 preferably equi-distantly spaced and having opposed arms radially alined. It is also preferred that the arms 4 be positioned adjacent the periphery of the plate 1. The outer end portions of the arms 1 are curved inwardly as indicated at 5 with their terminals preferably integrally connected. The curved portions 5 areadapted to have interlocked therewith a cable or other member '(not shown).

Disposed through the opening 2 are the elongated members M'having their opposite end portions substantially parallel and having intermediate portions6 offset inwardly to receive the marginal portion of theopening 2 as illustrated in Fig. 2 of the accompanying drawings, whereby the members M are held against undue longitudinal movement relative tothe plate 1 when the device is in assembled relation. The extremities of the members Mremote from the arms 4 are loosely directed through a cross member 7 which is held against displacement through the medium of the nuts 8 threaded upon the members M outwardly of the member 7. As herein disclosed the "nuts 8 are held against rotationby the locking pins 9 co-acting with the members M in a conventional manner. The portion of the member 7 intermediate the members M is reduced as indicated at 10 to permit the convenient engagement therewith of a cableor' other'member.

The opposite end portions of the members M are loosely directed through the cross member 11 which is held against displacement through the medium of the nuts 12 threaded upon the members M outwardly of the member 11 and said nuts 12 are also held against retrograde movement through the medium of the pins 14 coacting in a conventional manner with the members M.

Extending inwardly from the member 11 and positioned between the members M is a bearing block 15 which carries with the shaft 16 loosely disposed between the members M at the same side of the plate 1 from which the arms 4: extend. The end portions of the shaft 16 have rotatably mounted thereon the rollers 17 adapted to contact with the plate 1 and which serve as antifriction members to permit relative rotation of the plate 1 and the connected members M with a minimum of frictional resistance.

In the form of invention illustrated in Fig. 4 the plate 1 and arms 4* are substantially the same as has been set forth in the first embodiment of my invention with the exception that the outer portions of the arms 46 are inwardly offset as at 18 to further facilitate the engagement with said arms of a cable or the like. I Extending through the opening 2? of the plate 1 are the parallel portions 19 of the members M and the inner end of the straight or parallel portions 19 are provided with the shoulders 20 which serve to limit the movement of the portions 19 in one direction through the openings 2 The opposite end portions of the portions 19* are outwardly curved and have their end portions connected by the cross member 7 a for the same purpose as has been hereinbefore set forth relative to the member 7. Disposed through the outer extremities of the portions 19 of the members M is the shaft 16" having rotatably mounted thereon rollers 17 contacting with the adjacent face of the plate 1 to substantially eliminate frictional resistance upon the relative rotation of the plate 1 and the removable members M.

From the foregoing description, it is thought to be obvious that a swivel constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without materially departing from the principle and spirit thereof and for this reason I do not wish to be understood as limiting my self to the precise arrangement and forma- 1 tion of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

Copies of this patent max be obtained for five cents each, by addressing the tions of said anti-friction means carried by said shaft for contacting with the adjacent face of the annular member.

2. A swivel comprising an annular member provided with attaching means, elongated member's disposed through the bore of the annular member, the opposite end portions ofsaid elongated members being spaced apart, a cross head connecting the outer end portions of said elongated members, a shaft disposed between the outer end portion of said elongated members, antifriction members carried by the shaft for contact with the adjacent face of the annular member, and a bearing block carried by the inner end portions of the elongated members and coacting with the shaft.

3. A swivel comprising an annular member provided with attaching means, elongated members disposed through the bore of the annular member, the outer end por elongated. members being spaced apart, a cross head connecting said outer end portions of the elongated members, and anti-friction means carried by the inner end portions of the members for contacting with the adjacent face of the annular member. 7 p

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
