elevation of the secondary lever and its supporting-stud. Fig. 8 is a view of the said secondary lever and stud in rear elevation. Figs. 9 to. 14 are views illustrating the various modes of using the improved devices.
1 designates the loom-frame. 2 2 designate the harness-frames. 3 3 designate the usual cording or straps by means of which the said harness-frames are supported, and at 4: designate the sheaves over which the said cordi-n gs or straps pass. The foregoing parts are or may be of any suitable or desired character and construction, and the actuating devices by means of which movement is imparted to the harness-frames may be of any usual or suitable character.
5 designates a bracket which is' applied to the arch of the loom-frame, it usually being made adjustable on the said arch in a direction crosswise of the loom by means of a slot, as 6, formed transversely in the said bracket, through which slot passes the bolt 7 by means of which the bracket is secured to the arch. On this bracket 5'is mounted a stud 8, upon which latter in turn is mounted a lever 9, the
same being known herein as the main or supporting lever and having capacity to turn upon the said stud as on a pivot.
10 designates the hole which is formed in the said main or supporting lever 9 to receive the turned-or cylindrical projecting portion of the said stud 8. To the upper arm of the said main or supporting lever 9 is applied a stud 11, on which is mounted to turn a pair of harness- rolls 12 and 13, which latter are connected to turn together, the rear roll 13 being slightly the greater in diameter.
14. designates a stud that is applied to the lower arm of the said main or supporting lever 9, and on the turned or cylindrical projecting portion of the said stud 14 the second-- ary lever 15 is mounted with capacity to turn. The hole in the said secondary lever 15 which receives the stud 14 is designated 151.
16 designates a stud that is carried by the lower arm of the said secondary lever 15, and 17 and 18 designate harness-rolls which are mounted to turn on the said stud, the said rolls being connected to each other, so as to rotate in unison, and differing in diameter, as 'in the case of rolls 12 and 13.
19 designates a stud that is applied to the upper arm of the said secondary lever 15 and having mounted thereon a pair of harnessrolls 20 and 21, these last being connected to turn together and differing in diameter.
22 designates a second stud applied to the upper arm of the secondary lever 15.
The arrangement which is represented in the drawings is capable of working with six harness-frames.
Figs. 1, 2, and 9 show the manner of connecting and operating the harness cording or straps 3 o. The latter are in part omitted from Fig. 2 in order the better to illustrate the devices in which the invention resides more immediately. \Vith six harness-frames in use the front harness-frame will be connected by its cording or straps to the front roll 18, the second harness-frame will be connected to the roll 17, the third harness-frame will be connected to the roll 21, the fourth harness-frame will be connected to the roll 20, the fifth will be connected to the roll 12, and the sixth harness-frame will be connected to the roll 13. Vhen it is desired to employbut five harness-frames, the cording will be connected as in Fig. 10, in which latter the rolls 18, 17, 12, and 13 are utilized in connection with the cording or straps from the first, second, fourth, and fifth harness-frames, respectively, the cording 0r strap from the third harness-frame being connected with the stud or pin 22. lVhen it is desired to employ only fourharness-frames in the loom in which the invention is applied, the cording or straps from said harness-frames may be connected with the rolls 18, 17, 21, and 20, respectively, as indicated in Fig. 11. In this case, if desired, the main lever 9 may be held in a fixed position by suitable locking means. If desired, the cording or straps from the four harness-frames may be connected with the rolls 18, 17, 12, and 13, as in Fig. 12, and in this case the secondary lever 15 will be locked to the main lever 9, so that the said levers shall turn as one upon stud 8. Vhen it is desired to use only three harness-frames, the cording or straps therefrom will be connected, respectively, with the rolls 18 17 and with the stud or pin 22, as in Fig. 13, all carried by the secondary lever 15, the said levers being left free to turn with reference to main lever 9 and the main lever 9 being, if desired, held locked in a fixed position. \Vhen it is desired to use only two harness-frames, the cording or straps from the said harness-frames will be connected with the respective rolls of any one pair of the three pairs of harness-rol1sas, for instance, the rolls 18 and 17, as shown in Fig. 14and the two levers 9 and 15 may, if desired, be locked to render them immovable.
The devices which have been described above can be used for working four, three, or two harnesses without holding or securing the levers, if desired. For convenience in locking or holding the levers when desired or required the devices are usually provided with locking means of convenient character. The
drawings show the following means or arrangements for enabling the looking or holding of the levers to be effected.
The supporting-stud 14 for the secondary lever 15 is rendered adjustable in the direction of the length of such stud in the hole 141, which is formed in the lower arm of the main lever 9 for the reception of the stud. The stud 14 is formed with a shoulder, as at 142, at the inner end of the turned or cylindrical portion, on which the secondary lever has bearing, against which shoulder the boss 152 on the said secondary lever 15 makes contact. On the lower arm of the main or supporting lever 9, at opposite sides of the hole 151 for the reception of the stud 14, the projecting lips or ribs 144 144 are provided. The boss 152 on the rear side of the secondary lever 15 is flattened on its opposite sides, as shown in Fig. 8, and by adjustment of the stud 14 the said boss may be caused to enter between the said lips or ribs 144 144, if desired, and thereby the secondary lever 15 will be prevented from turning relatively to the main or supporting lever 9, so that both of the said levers will turn in manner like unto that of a single rigid lever about the stud 8. 143 designates the clamping-screw, by means of which the stud 14 is held in either of the desired positions of adjustment in the hole 141 of the lever 9. The stud 8 is adjustable in the direction of its length through the hole 93, to which it is fitted in the bracket 5, and the said stud 8 is held in the desired position of adjustment in such hole by means of the clamping-screw 94. 95 designates the shoulder on the stud 8 at the inner end of the turned or cylindrical portion, on which the said main lever 9 is mounted and against which shoulder the said lever 9 makes contact. 13y making proper adjustment of the stud 8 the portion 91 of lever 9 may be caused, when desired, to enter between the rib or lips 92 92, which are formed on the bracket 5 on the opposite sides of the hole 93 in the said bracket, and thereby the lever 9 may be held from turning movement.
lVhen it is desired to work four or three harness-frames without holding the levers, the main or supporting lever 9 may be allowed to fall or turn partly over under the strain which is transmitted through the harness connections, so that its lower arm shall extend inwardly in obvious manner, or the supporting-lever 9 may be omitted, and the secondary lever 15 may be applied to the supporting stud 8. frames the levers 9 and 15 (in case the entire arrangement is retained in place) may be permitted to swing inward under the strain that is transmitted through the harness connections. .If the main or supporting lever 9 is removed and the secondary lever 15 is mounted on the supporting-stud 8, then in that case the said secondary lever 15 will be allowed to swing, as noted. If desired, both the levers may be removed, and a pair of rolls corre- In working two harness sponding with 17 and 18 may be mounted on the supporting-stud 8 for two-harness work.
It will be observed that all of the pairs of rolls are alike.
Among the advantages of the invention are the facts that the mechanism is self-contained and complete for six harness-frames or less, that all strappings from the various rolls are in line with the respective harness-frames to be operated, that only one size of double pulley or pair of rolls require to be used in each of the places where the same is represented in the drawings, and that the mechanism is so designed as that the stud 8 of the bracket 5 may constitute the support of either the en tire combination of movable levers and rolls or of a single lever or of a single double pulley or pair of rolls.
What I claim as my invention is- 1. The combination with the loom arch or stand, of a main supporting-lever having a pair of harness-rolls mounted to turn on one arm of said lever, the secondary lever mounted pivotally on the other arm of the said main lever, the pair of harness-rolls mounted piv- I otally on one arm of the said secondary lever, the other arm of said secondary lever having means of receiving harness-cording, substantially as described.
2. The combination with a support, of the main or supporting lever mounted pivotally on the said support, the pair of harness-rolls mounted to turn on one arm of the said lever, the secondary lever mounted pivot-ally on the other arm of the said main lever, the pair of harness-rolls mounted pivotally on one arm of the said secondary lever, the other arm of said secondary lever having means of receiving harness-cording, and means of holding, respectively, the main lever from movement relatively to the support and the secondary lever from movement relatively to the main lever, substantially as described.
3. The combination with the support, of the main or supporting leverv mounted pivotally on the said support, the pair of harness-rolls mounted to turn on one arm of the said lever, the secondary lever mounted pivotally on the other arm of the said main lever, and the respective pairs of harness-rolls mounted pivotally on the respective arms of the said secondary lever, one arm of the said secondary lever having in addition means, as the pin 3, of receiving harness-cording, substantially as described.
4. The combination with the support, of the main or supporting lever mounted pivotally on the said support, the pair of harness-rolls mounted to turn on one arm of the said lever, the secondary lever mounted pivotally on the other arm of the said main lever, the respective pairs of harness-rolls mounted pivotally on the respective arms of the said secondary lever, one arm of the said secondary lever having in addition means, as the pin 3, of receiving harness-cording, and means of holding, respectively, the main lever from movement relatively to the support and the secondary lever from movement relatively to the main lever, substantially as described.
5. The combination with the lever 15 and a support or mounting therefor, of the pair of harness-rolls mounted pivotally on one arm of the said lever and'the pin mounted on the other arm of the said lever for receiving harness-cording, substantially as described.
6. The combination with the support, of the main or supporting lever, the secondary lever pivotally mounted on one arm of the said main or supporting lever, the other arm of said main or supporting lever and both arms of the said secondary lever having provisions for the attachment of harness-cording, and means of locking when desired the said main lever to the support and the secondary lever to the main lever, substantially as described.
