The lever 19 is operated by the shipper-lever 24 through connector 22 and angle-lever 23, pivoted at 23' and connected with the shipper-lever 24, pivoted at 25, all in the ordinary way. On the outer end of the cross-shaft 14 is fast a belt-pulley 26, driven by a belt. (Not shown.)

The operation of myimprovements in driving mechanism of looms is briefly as follows: Power is communicated to the cross-shaft 14 through belt-pulley 26, and the friction-disk 18, splined on the shaft 14, revolves with said shaft, and when the shipping-lever is on and the loom is in operation the friction-disk 18 -will be in engagement with the frictiondisk 12, causing said disk and bevel-gear 11 to rotate with the disk 18 and the shaft 14 and communicate motion to the gears 8 and 9. When theshipper-lever is moved to stop the loom, the friction-disk 18 is moved out of engagement with the friction-disk 12, leaving the friction-disk 12 and bevel-gear 11 stationary, While the shaft 14 and the friction- The attendant disk 18 continue to revolve. in pushing back the lay from the position shown in Fig. 1 to its rear position will only have to reverse the gears 8 and 9 and the bevel-gear 11 and friction-disk 12 without moving the shaft 14.

In starting up the loom by moving the shipper-lever and causing the friction-disk 18 to move into engagement with the frictiondisk 12 the momentum of the revolving shaft 14 will cause the loom to start more quickly than if the shaft 14 were stationary at the time the loom is started, and the bevel-gear 8, meshing with the bevel-gear 11, will tend to crowd or push the gear 11 outwardly.

The advantages of my improvements will be readily appreciated by those skilled in the art. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In the driving mechanism ofv a loom, the combination with the cross driving-shaft, mounted and turningin boxes or bearings on the frame, a belt-pulley fast on one end of said shaft, and a friction-disk splined on the other end of said shaft to revolve therewith and have a sliding motion thereon in the direction of the length of the shaft, and means for moving said friction-disk, of a sleeve mounted on said shaft, and means for hold.

ing the sleeve to prevent motion in the direction of the length of the shaft, and a bevelgear, and secondrfriction-disk loosely mounted on the sleeve, and means for preventing said gear and friction-disk from moving in the direction of the length of the sleeve, substan tially as shown and described.

2. In the driving mechanism of aloom, the combination with the cross driving shaft, mounted and turning in boxes or bearings on the frame, a belt-pulley fast on one end of said shaft, and a friction-disk splined on the other end of said shaft to revolve therewith and have a sliding motion thereon in the direction of the length of the shaft, and means for moving said friction disk, of a sleeve mounted on said shaft, and having a Iiange on one end thereof, and acollar on said sleeve, and a bevel-gear, and friction-disk loosely mounted on said sleeve, between said flange and collar, substantially as shown and described.

3. In the driving mechanism of a loom, the combination with the cross driving shaft, mounted and turning in boxes or bearings on the frame, a belt-pulley fast on one end of said shaft, and a friction-disk splined on the other end of said shaft to revolve therewith and have a sliding motion thereon in the direction of the length of the shaft, and means for moving' said friction-disk, and a sleeve mounted on said shaft having a flange on one end thereof, and a collar on said sleeve, and a bevel-gear and friction-disk loosely mounted on said sleeve between said flange and collar, said friction-disk and bevel-gear having au internal annular oil -reservoir, substantially as shown and described.

4. In the driving mechanism of a loom, the combination rwith the cross driving-shaft, mounted and turning in boxes or bearings on the frame, a belt-pulley fast on one end of said shaft, and a friction-disk splined on the other end of said shaft to revolve therewith and have a sliding motion thereon in the direction of the length of the shaft, and means for moving said friction-disk, of a sleeve mounted on said shaft, and having a {iange on one end thereof, and held on said shaft by bolts extending in recesses in said sleeve, which bolts secure the cap-piece to the shaft box or bearing, and a bevel-gear and frictiondisk loosely mounted on said sleeve between the flange on said sleeve and said shaft box or bearing, substantially as shown and described.

5. In the driving mechanism of a loom, the combination with the cross driving-shaft, mounted and turning in boxes or bearings on the frame, a belt-pulley fast on one end of said shaft, and a friction-disk splined on the other end of said shaft to revolve therewith and have a sliding motion thereon in the direction of the length of the shaft, and means for moving said friction -disk, of a sleeve mounted on said shaft, and a bevel-gear and friction-disk loosely mounted on said sleeve, said bevel-gear and friction-disk having an internal annular oil-reservoir for oil to lubrioate the sleeveA and shaft, substantially as shown and described.
