Abstract: A tool for countersinking nails into a workpiece has a base member, which is formed of resilient material, and has a generally flat bottom section resting on the workpiece. A metal guide is mounted in the base member. The guide has a central opening for receiving a nail in its bottom. A rigid cap member on the base above the guide has an aperture through it, and a nail set extends partially upward out of the aperture in the cap and extends into the opening in the guide above the nail for transmitting impact from a hammer on the nail. The bottom of the guide member is recessed from the bottom surface of the base so that the metal will not contact the workpiece. The cap has a greater diameter than the guide so that if the cap is struck when the bottom or the nail set is below the top of the workpiece, an impact on the cap is not transmitted to the guide but will be absorbed in the resilient material of the base. A nail starting section integral with the base member extends laterally outward. It contains starting holes that grip nails initially. A slot extends from each opening to a larger opening, and the tool can be pulled over a nail until the nail is in the larger opening where it can be removed from the nail.

Abstract: 15,401. Thomas, J. Nov. 1. Auxiliary actuating- gear; cam - actuated pumps; lever-actuated pumps; double-acting bucket - pumps; multiple-delivery bucket pumps; combined piston and bucket pumps; pumps in series; regulating delivery by closing suction valves; suction reservoirs; v a l v e s , arrangement of. - A mechanical lubricator comprises one or more double-acting pumps in which a single valve, preferably cylindrical, is positively moved by the pumping strokes of two plungers. In the form shown in Fig. 1, two double-acting pumps are combined, each comprising two parallel tubular plungers 4, 4 and 5, 5 working respectively in chambers 16, 9 and 16 , 9 . The plungers 4, 4 are connected by a crosshead 22, and the plungers 5, 5 by a double cross-head 23, in which rotates the actuating cam or eccentric 33. The plungers 4, 5 are in alinement and connected by a hollow member 6 containing a chamber 12, in which the cylindrical valve 13 works. The pump chambers 16, 16 are formed in adjustable screws 17 mounted in the walls of the reservoir, and the chambers 9, 9 in a stationary member 7 mounted in the reservoir. The chamber 12 is connected to the chambers 9, 9 by ports 14, 15 and passages 14 , 15 , and with the chambers 16, 16 by the passages 11. During the suction stroke of the plunger 4, oil enters the chamber 16 through the port 18 or channels in the outer surface of the plunger, and during the return stroke, this oil passes through the passage 11 and forces the valve 13 to the right and passes through the duct 14 to the chamber 9. During the next suction stroke of the plunger 4, half of the oil in the chamber 9 is forced through the plunger 4 into the delivery pipe 21, and half fills the space 20 evacuated by the outer part of the plunger which has half the crosssectional area of the part working in the barrel 9. During the next return stroke of the plunger 4, the oil in the space 20 is forced into the pipe 21. The same series of operations take place in the other pump 5, 5 . The crosssectional area of the outer end of the plunger 4 is the same as that of the inner end of the plunger 4 . The eccentric 33 is driven from the shaft 38 through ratchet gearing. The cam shaft 34 may be actuated by a hand-whee! for flushing purposes. In the modification shown in Fig. 3, two plungers 43, 43 are in alinement and connected to an intermediate piece 6 reciprocating in a bearing 46 screwed into the wall of the reservoir. Oil enters the pump chambers 44, 44 through channels 55, 55 in the plungers and, on the delivery strokes, passes through the ports 48, 48 to the delivery pipe 51. The plungers are reciprocated by a lever 59 actuated by a cam &c. 33 driven as before described. In both forms, the delivery may be regulated by adjusting the screws 17, 17 &c. so as to vary the point at which communication between the pump chambers 16 &c. and the reservoir is cut off during the delivery strokes. A number of pumps may be mounted in the same reservoir.

Abstract: 13,276. Thomas, J. Aug. 26, 1912. [Cognate Application, 13,277/13.] Fire-bridges; baffles. -Air is supplied to the rear of a furnace through a special passage in the fire - bridge controlled by a damper as described in Specification 23,797/10, and dog-pieces are provided for securing the bridge in position. The airpassage 13, Fig. 1, is inclined at the bottom to facilitate the escape of dust or ashes, and its outlet at the top faces upwards and rearwards. The passage is of uniform sectional area throughout, and is the full width of the furnace at the top. Dogpieces 22, Fig. 3, bearing against the side and top of the bridge and the side 27 of the furnace, secure the bridge in position. The thrust at the top of the bridge is taken by studs 28. A baffle-plate or the like may be secured in a similar manner.

Abstract: 24,329. Thomas, W., and Thomas, J. Nov. 2. Treadle mechanism. - In treadle gear for cycles, of the kind in which oscillating levers S are connected by one-way clutches T to a rotatable shaft within the rear-wheel hub, the motion being transmitted from the shaft to the hub by a twin-chain gearing-up mechanism, a supplementary hub X is provided upon a shaft disposed immediately in front of the road wheel between the lower fork members U, this hub being furnished at one end with a pair of chainwheels R, V which co-operate with a wheel D mounted upon the tubular driving-shaft C and with a small free-wheel B upon the road-wheel hub. The wheel D and the one-way clutch T at the right-hand end are mounted upon a screw-threaded cone D integral with the shaft C; the one-way clutch at the opposite end is mounted upon a cone J screwed upon the driving-shaft and secured by a screw L engaging one of a number of grooves G, Fig. 2, running across the thread of the shaft.

Abstract: 10,310. Thomas, J. and Lewis, J. L. April 30. Buffers.-The spring buffers of wagons are retained in their casings by a divided ring and a collar of special form, which also serves as an abutment for the volute spring. The bufferplunger c is recessed at c , and in the recess a divided ring d is placed. A disk or washer e keeps the ring in place by bearing on the outer surface of the ring and also on the part of the stem beyond the recess and on a reduced portion of the stem. The tubular extension e' fitting this reduced portion may be made separate from the disk. A pin f holds the parts together.
