Patent GB-190901946-A (GB)
Title: New or Improved Percussive Drill, Hammer or like Percussive Tool or Machine.
Inventor: SYKES ALFRED
IPC: E21B1/38
Filed: 1909-01-27
Granted: 1910-02-28
Abstract: 1946. Sykes, A. Jan. 27. Percussive drills; percussive channelling- drills.-Relates to percussive tools for undercutting rock, drilling, cutting, or hammering, of the type in which an elastic substance is compressed in the machine itself. As shown in a drill in Fig. 2, a piston 1 is reciprocated from a motor through gearing 10, a crank disk 7<a>, a connecting-rod 7, and a suitably-packed tubular rod 1<a>. When, during its rearward stroke, the piston passes air-holes 21, cushioning occurs and causes a rear cutter-operating piston 2 to move to the rear, compressing air in the space behind this piston 2 or in a separate chamber. At the end of the stroke, the air between the pistons passes through ports 22, a valve 25, and ports 23, to the space behind the piston 2, to make up for leakage. As the driving-piston 1 then moves forward, the air compressed behind the cutter-piston 2 expands to force the piston 2 out for its working stroke. The valve 25 may be secured on the cutter-piston 2. A safety valve 27 regulates the pressure. In a modification, springs are used instead of air behind the cutter-piston, the air between the pistons being ejected at the end of the stroke. Springs may also be interposed between the pistons. Intermittent rotation is imparted to the tool by a spirally grooved part of the piston-rod 2<a> engaging a nut 15, which is connected by a friction clutch 17 built up of sliding rings and interposed fibre washers, to a ratchet-wheel 16 held against rotation in one direction by pawls, the clutch slipping when undue stress occurs. When the machine is of the hammer type, this rotation is conveyed to the tool through a sliding sleeve, keys, and key-ways. The rotation gear may be placed at the rear of the machine. The machine is carried in a cradle, which may be provided with ball or roller bearings and is fed to its work by a screw and nut, the motion being conveyed from the nut through the medium of springs. The cradle is mounted in a boss 28<a> in a bracket 28 on an adjustable column 30, and swung by means of a worm journaled in bearings 28<b> and engaging a wormwheel. The bracket 28 may be rotated by means of a worm engaging a worm-wheel 41 held against rotation and may be adjusted vertically by means of a nut 29<a>. The machine may also be mounted on wheels and fed bv means of an inclined board, or may be fixed on a sledge, or it may have studs to receive wheels for transport purposes. For lighter machines, the driving-piston 1 may be reciprocated by a crank engaging the cross-head 6 and driven by a flexible shaft, and the machine may be manually held. A timing-valve may be employed for the air chamber. The Provisional Specification also states that the machine may be fed by a screw rotated by a falling weight or by means of a spiral spring, and in structural work may be held by electro-magnets.

Title: Improvements in Apparatus for Compressing Fluids for Operating Pneumatic Tools
Inventor: LAKE HAROLD WILLIAMSON
IPC: F04B49/16
Filed: 1909-03-23
Granted: 1909-08-26
Abstract: 6981. Lake, H. W., [Ingersoll-Rand Co.]. March 23. Power hammers.- Relates to pulsator pumps for compressing fluids for operating pneumatic tools and consists in providing a clearance space at one end of the pump cylinder in order to render the pump inoperative when the pressure in the system has been raised to the working pressure. The fluid enters the pump cylinder 12 through an inlet valve 15 and is delivered through an outlet valve 16 to the pulsator cylinder 7, from which it is discharged by means of the pulsator piston 8 alternately from opposite sides through pipes to the tool. The pump piston 13 forms an extension of the pulsator piston 8, which is operated by means of an electric motor 3 through gear wheels 4, 5. A clearance ring 18 is provided at the end of the cylinder, forming a clearance space of such capacity that the pressure of the fluid therein, when the pump piston 13 is at the forward end of its stroke, is equal to the working pressure. By this arrangement, when the pressure in the system is of the required amount, the pressure in the pump cylinder 12 is never less than the exterior pressure, or greater than the working pressure and consequently the valves 15, 16 are rendered inoperative. To suit different working pressures, clearance rings of different widths may be employed. The invention may be applied to pulsators of any type.

Title: Improved Micrometric Measuring Instrument.
Inventor: ROCH PIERRE
IPC: G01B7/06
Filed: 1910-08-29
Granted: 1911-03-23
Abstract: 20,081. Roch, P., and Challet, E. Aug. 29. Linear-dimension gauges.-In a micrometer gauge provided with electrically-operated means for arresting the graduated head or drum when the micrometer screw is in a position corresponding to the required dimension, the electric circuit is only momentarily energized, and is broken directly the micrometer screw is arrested; the life of the battery is thus prolonged. The adjustable head is carried by a tubular non-rotating nut engaging with the micrometer screw, to which is attached a member adapted to reset the electric arresting-means when the screw and nut are bodily withdrawn to allow the object to be measured to be inserted between the measuring - heads. The tubular nut b<1> is prevented from rotating by an arm I co-operating with a scale O. To take a measurement, the screw C is first brought approximately into its zero position when the adjustable head b is in contact with the head a. The head b, together with the nut b<1> and drum C<1>, are then bodily withdrawn, and the object to be measured inserted; the withdrawal of the screw rocks a lever N by means of an attached collar m, and positions a lever h so that it engages with the notch in a spring- controlled armature f, and forces a contactspring g into engagement with an insulated contact-screw G. The head C<2> of the screw is thereupon turned until its lower end c engages with the cross-bar D, whereupon the circuit, which includes a cell E, is completed through the casing and the contact-spring g, and the lever h is released and rocked by the spring g, thus causing the end of a bent lever i to engage with one of the teeth of the drum C'. The circuit is broken by the disengagement of the spring g from the contact-screw G.
