TO ALL WHOM I T MAY CONCERN: Y
Beit known that I, BARTON H. JENKS, of Bridesburg, in the countyA of Philadelphia, and Stateof Penn- Sylvania, have invented an Improvement in Cams for Operating lreadles in Looms for Tweeling; and` I do hereby declare' that the following is a full, clear, and exact description thereof, reference being had to the accom panying drawings, making a part of this specification, in which# Figure 1 is a horizontal section cfa loom taken above the cam-shaft, showing myimproved-eam applied to it.
Figure 2 is an enlarged view ofone of the improved grooved cams.` I
Figure 3 is an end view -of the same.
Figure '4 shows in a cross-sectiou the two parts of the groov'edcam detached. v
Similar letters of reference indicate corresponding parts in the several igures.
This invention relates to an improvement on looms which are designed for weaving twilled fabrics, and in which reciprocating cams are employed 'as described in the patent of Richard Garsed, whichwas grunted on i the 20th day of July, 1846, and extended onthe 18th day of July, 1860, and subsequentlyassigned.to me In this loom of Garsed tho cams are placed upon the middle or" the cam-shaft between the intermediate bearings thereof.` This cam-shaft'is also employed for driving other parts of the loom besides the treadles, such as the piek motion, thread-protectormotion, box motion, Sto. When a change was necessary from one grooved hub or cam to anotl1er, having a greater or less number of grooves, all the said connections were displaced, the
' cams removed from the shaft by sliding them oii endwise, the new cams substituted for those last in use, and
adjusted -in proper position and relation to the treadles, after which the cams and. dogs for actuating other parts of the loom-abovereferrcd' towere adjusted upon the shaft Vin proper time and relation to eachother, requiring considerable labor, time,`and skill. Y
The object of myiinvcntion and improvement isto so construct the grooved hubs, s leevcs, or cams which a'ctuatc the trcadle-camaithat allthe required. changes can be made for moving agreater or less number of trcadles, or for. moving a givenj number of treadles in any required order, by simply removing those `portions of said hubs or sleeves which' produce said changes, and without the necessity of removing the cam-shaft from itsbe'arings or disturbing such parts'as may be connected to this shaft, as will be hereinafterdescribed.
To enable others skilledl in the art to understand my invention, I will describe its construction and operation. In the accompanying drawings represents the cam-shaft, having the picker cams a a securedvpermanently to it in the.4 usual manuel-,land'C C are the harness cams for acting upon the treadles o, of which six are rcplresented', the number required for three sets of-harnessfor weaving threeftwilled cloth. The cams C C are secured in a suitable manner-to cylindrical hubs, D D, that slide freely on the shaft A in an endwise direction, and at the sametime furnwith it by means of a feat-her or key tenen, c.v In Eg. 1 the hubs D D are each represented with three grooves, at equal distances apart, passing around its periphery.' On one side of' each hub the straight portions of the grooves run into other grooves passing obliquely over 4the surface of the hub so as tointersect eachother, as shown,lin two directions. F F represent two horizontal studs projeeting from the frame G, and on theinner endof each stud turnsa feather, d, which fits the grooves inthe hubs' D freely, and which is made of such length, with `the'ends reduced in thickness, as to' pass the junctions of the diagonal portions of the grooves where they cross each other. When the diagonal portions of the-grooves pass the feathers, the smallest diameter ofthe cams'C C passtlietreadle, at which time the cam and treadles are not in Contact, and therefore the former are free to 4slide on the' shaft A without touching the treadles. By increasing the nnmber of grooves in each hub any desired number of treadles can he operated. l
Having described the manner of operating the treadles of looms for weaving twilled fabrics, I will novy describe my improved' mode of constructing the grooved hubs or cams D D, which give the ends/isc movements to the treadle cams O C, so that the required changes can be made without removing the main shaft A. from its bearings. The grooved hubA shown in figs; 2, 3, 4, and 5 consist-s of two parts or segments, D and D', whichform a. complete cylinder when put together, as shown in figs. 2 and 3. The largest segment, D, is permanently, but loosely, applied on thecam-shaft A, and is secured rigidly to the cam C, which works the treadles. The smaller section or segment D is constructed'with'lips or tcnonsupon its ends, which fit 'snugly into corresponding recesses formed in the portion D, as Slro,wn`and by means'f screws this segment D is rmly secured to the segment D, tltinsforrning` zn perfect cylinder. That portion of the hub which is permanently-,attached to the shaft A, but allowed to slide' endwise thereon, has straight and parallel grooves formed in its periphery, which are lettered gg g, and that portion or" the hub which is removable has oblique or diagonal grooves,g g', g', formed in its periphery, which grooves are equal in width to the straight lor parallel grooves in the portion D, and form, together, channels for receiving the feather d, and causing the hub and its cam C to receive an endwise reciprocating movement on the shaft .A when the latter is turned. The segment D', which has the oblique intersecting grooves formed in it, is made removable from the segment D for the purpose of employing another segment of the sume size and shape, when it is desired to employ a. greater or less number of-'grooves and ngreater or less number of' treuriles. Therefore, when a., change is required, it is only necessary torcmove the diagonally grooved segment D and substitute a. dierent onewhich will give the required change. i
Having described my invention, what I claim as new, anddesireto secu re by Letters Patent, is Y Constructing the grooved hub -ofna trendleam, C, of' two-parts, substantially in the manner and for the purpose described.
