Abstract: 106,366. Kuhn, H. A. July 27, 1916. Coal-cutting machines; excavating.-An undercut or other cut is made in the wall or seam of coal, and then, by explosive charge or otherwise, the coal is expanded or disrupted, after which a cut or opening is made, with a vertical lifting force, in the settled mass, so dislodging it for removal by the conveyer. The apparatus employed consists of a primary cutting unit 36, Fig. 7, and a secondary cutting and conveying unit 2, Figs. 6 and 7. The primary cutting unit is of ordinary endless-chain construction, actuated, for example, by an electric motor 35. When a primary cut or undercut is to be made. the cutter is run off the machine 2 to the position required, and after the cut has been made, its feed-rope is connected to the hook 46, and it is drawn back by its own power on to the machine 2, where its motor is brought into gear with the clutch box 33 to effect the operation of the secondary machine. After disruption of the coal by explosive &c., the machine 2 is advanced to the settled mass, and the endless conveyer 54 is actuated to excavate the loosened coal and convey it to the pit wagon 59. The machine 2 is supported by two driving-wheels 5 and a forward castor-mounted roller 47; the roller 47 can be turned by the rope 48 from the crank-handle 51, to direct the machine to the desired position. The wheels 5 are driven from the motor 35 through the spur gearing 31, 30, 28, 27, worm gearing 25, 24, chain gearing 22, 21, 20, and friction gearing 8, 7, the friction disk 8 with the chain-wheel 20 being hung on links 10 connected to a toggle-mechanism 12, 13, 16, whereby, by operating a hand-lever on the axis 17 of the member 16, the friction disk 8 can be put into or out of gear with the disk 7. Drills 70, connected by flexible stem 71 to driving spindles 72, are provided for drilling the shot holes. A pivoted dog 65, toothed at its end 66, can be thrown over into the position shown in dotted lines in Fig. 7, when it is necessary to force the front of the machine upwards, to clear an obstruction. A pivoted skid 62, which can be turned up, as shown in Fig. 7, when not in use, is provided to facilitate the movement of the primary cutter off and on to the machine 2. The endless conveyer 54 is driven from the motor 35 by the bevel-gearing 61, 60, the flights of the conveyer being provided with tips 55<1> bevelled at their outer ends, and preferably constructed to exert a further upward thrust on the loosened mass of coal during their excavating action. This upward thrust may be effected by the bolts, Fig. 8, which secure the tips 55<1> to the flights, or by projections 56<a> Fig. 9, on the flights. In another form, the tips are integral with the flights and are bevelled at each side as well as the end. In the form shown in Fig. 14, the tip is provided with a transverse shoe 55<a>.

Freed, by wheels and by dogs; sack sewing- machines.-A machine particularly adapted for closing the tops of filled bags by a reinforced seam, has a pair of feed wheels actuated intermittently in timed relation to the feed dog, for avoiding strain on the sewing needle regardless of the weight and size of the bags. The wheels 16, 17 are mounted on axles 18, 19 and close the mouths of the bags ready for the stitching needie 52 which usually operates horizontally. The dog 15 feeds tapes from guides 50, 51 to reinforce the seam. The wheel 16 is driven by a pawl 26 engaging the teeth of an integral ratchet wheel 20. The pawl is pivoted at 27 to an arm 25 oscillated by the shaft 22 which is rocked by an arm 23 connected by a link 24 to an eccentric on pawl 39 pivoted at 40 on an arm 38 oscillated by the main shaft 11. The wheel 17 is driven by a a shaft 32 rocked by the shaft 22 through the linkage 37. Pawls 29, 42 prevent backward rotation of the feed wheels. The axle 18 of the lower wheel is fixed, but the axle 19 of the upper wheel is mounted on a block 57 of a sleeve 56 sliding on the stem 55 carrying the presser foot 14. A spring 53 presses down the stem 55 and a spring 54 presses down the sleeve 56. Relative movement between the rollers and presser-foot is therefore permitted. A cam 70 can be turned by a lever 72 to lift the U-shaped member 64 sliding on the stem 55, to cause its upper limb 65 to engage the collar 66 to lift the presser-foot and its lower limb 67 to engage the collar 68 to lift the sleeve 56 and block 57 carrying the upper feed wheel. To prevent the momentum of the bag and feed wheels from turning further than they are pushed by the pawls, friction brakes 81, 87 controlled by nuts 84, 90 are provided. Presser-feet.-The foot 14 carried by the stem 55 is adjusted to bring its needle hole 78 into correct relation with the needle by the eccentric reduced part 76 of the shaft 73. Cutting.-At the side of the seam is a stationary knife 43 and a moving knife 45 carried by the lever 44 connected by an arm 44' to the rock shaft 22. A resilient pivoted member 47 normally prevents the seam from coming into the path of the knives.
