' @Rowman ASA J. DRAPER,

STRAND OF OGDEN, UTAH.

TWISTER.

Application led November 23, 1922. Serial No. 602,829.

To all who/m, it 'may concer/nf: c 'Be it known that I, ASA J. DRAPER, 4la. citizen of the United States residing at Ogden, in the county of lVeber and State of Utah, have invented certain. new and useful Improvements in Strand Twisters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

Y My invention relates to improvements in devices for twisting together a plurality of strands of cord or wire for the: purpose of forming a rope or cable. The device is'of the general nature of prior devices having a plurality of circumferentially spaced ro tatable hooks for twisting the `strands so that they will later twist about each other.

It is the object of the present invention however to improve upon the construction of prior devices of the same character, to such an extent that an extremely simple and inexpensive device is provided, yet one which will be highly efficient and durable. v

lVith the Jforegoing in view, the invention residesin the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is a perspective view of a strand twister constructed in accordance with my invention, showing the manner of twisting a number of strands together.

Figure 2 is a vertical sectional view as in? dicated by line 2-2 of Fig. 1.

Figure 3 is a vertical sectional View at right angles to Fig. 2, as indicated by line 3-3 thereof.

Figure 4 is a sectional view as indicated by line 4-4 of Fig. 1.

Figure 5 is a perspective view of one of the strand twisting hooks.

In the drawings above briefly described, the numeral 1 designates a flat front plate which is preferably of substantially circular form. being provided however with a depending eXtension 2 by means of which it may be rigidly secured to an appropriate support. The openings 3 which I have shown in this plate are principally to s'ave metal and decrease weight, but attention is directed to the fact that the spout of an oil can may be inserted through these openings for oiling the pinions yet to be described.

Plate l is formed with a relatively large central opening 4 vand with a plurality smaller circumferentially spaced openings 5 which are equidistant from said central opening. The plate is v`preferably stamped from ya single piece of metal of suitable gage c and allfof .theppenings'niay be formed in ysaid plate lby. a single stamping operation, p

at the time of cutting the plate the desired shape. The openings 5 Vrotatably receive the shanks ofga vplurality of twisting hooks 6,'the rear ends of said hookshaving yfiat heads17 ,which are preferably although not necessarily: of the square form shown, These heads 7 are snugly received in ysimilarly shaped openings 8 in a plurality of flat pinionsr9 which contact with the rear side of the front platel and it will thus be seen that rotation of said pinions will rotate theseveral hooks totwist strands in the required manner..v -4 Y The front end of a bearing sleeve 10 is snugly received inthe centralopening l4 of the front platel 1,'this sleeve being provided Vwith' lan outstanding flat flange 11 whichis so that said rear plate may rotate uponsaid f sleeve, the two plates 1 and 12 being spaced apart sufficiently to prevent binding the pinions 9 and the heads 7, by means of the flange 11.

I provide common mea-ns 'for securing the bearing sleeve 10 snugly inthe opening for 4 of the front plate 1 and for preventing the rear plate 12 from moving rearwardly ofl' of the bearing sleeve. I prefer to pass an ordinary bolt 14 through the sleeve 10, this bolt being providedwith a washer 15 between its head 16 and the front plate 1 and having another washer 17 which is clamped against the rear end of the sleeve 10 by the nut 18. The space between the flange 11 and the washer 17 is slightly greater than the thickness of the disk l2, whereby the latter may freely rotate. The peripheral portion of this back plate or disk 12 is provided with a fiat internal gear ring 19 which is secured thereto by any preferred means such as rivets 20, said gear ring meshing with the pinions 9 for rotating all of the latter and the hooks 6, when the back plate 12 and said gear ring are rotated, for inmay beeasily and inexpensively manufactured and marketed,y yet it will beV efficient stance by means of a suitable handle 2l. This handle may well be secured to the plate or disk 12 by bolts or rivets 22, one of which A preferably passes through the gear ring 19 as disclosed in Fig. 2, thereby assisting in securing it to the plate l2. All parts so far described are stamped from suitable gage sheet metal with the exi ception of the bearing sleeve l0 and the hooks 6. The sleeveand its flangell are preferably turned, while the hooks andv their {'hea'ds 6 may be drop forged. 'Byemploying a construction which maybe constructed in these well known ways, that is principally of the stampings and forgings, the 'device and durable.

y'Preferably used in connectionl withV the features above described, is a suitable vthreader or strand guide 23 which may'well be stamped from a metal plate. 'The strands to be twisted are suitably engaged with notches 24 of this device and with `the hooks 6V and the threader 23 is then held against rotation while the handle 2,1 is operated to simultaneously rotate the hooks G in the same direction. This twists the several groups of strands together and when the desired` ably followed. However, within the scope -aiiixed my signature.

oit the invention as claimed, numerous minor changes may be made;

I claim:

. l. A strand twister comprising a flat rigid front plate having a plurality of circumferential'ly spaced openings, a plurality of twisting hooks having shanks rotatable in said openings, the rear ends oit said'shanks having fiat heads bearing against the rear side of said front plate, flat pinions contacting with said rear side of said front plate and having central openings non-rotatablyv receiving 'said heads,a rotatable back plate engaging the rear sides of said pinions and said heads land having an internal gear ring meshing with said'pinions, and means rotatably inountingsaid back plate on-said front plate.

2. A" strand twister comprising a rigid liront plate having a substantially central" opening and circumferentially spaced openings equidistant from said central opening, twisting hooks having lShanks rotatable in said circumferentially spaced openings,l fiat pinions'connected with the rear ends of saidA 4Shanks and contacting with the vrear side of said front pla-te, a bearing sleeve snugly receivedin said central opening of said front vplate and having an outstanding flange contacting with the rear side of said plate, said flange and A pinions being of substantially -uniform thickness, a rotatable back plate Vhaving a central opening receiving therear endfot'v said bearing sleeve, said back plate having an internal gear ring meshing with said pinions, and a bolt passing through said bearing sleeve, said bolt securing said sleeve to said front plate and Vpreventing removal of said back plate from said sleeve.

In testimony whereof I have hereunto ASA J. DRAPER.
