Title: Improvements in or relating to tunnelling machines
IPC: E21D9/10
Filed: 1919-12-04
Abstract: 159,342. Whitaker, D. Dec. 4, 1919. Tunnelling by boring.-Means for advancing the cutters of tunnelling-machines comprises a stretcher-bar disposed transversely of the bore in rear of the machine, grip devices on opposite ends of the bar adapted to be brought into and out of gripping contact with opposite sides of the bore by a lengthwise adjustment of said bar, and feeding-means having a thrust member connected to the grip devices on the transverse bar by togglebars disposed angularly relatively to the transverse bar. The carriage 1 of the travelling- machine, Figs. 1 and 2, moves on wheels 2 along the bore 3 made by the rotary cutter 4. The thrust of the machine is taken by two pressure plates 5 having faces 6 for engaging the face of the bore, these plates being mounted on the ends of a stretcher bar 7, Fig. 4, fitted with a screw - and-nut device 8, 9 operated by a hand-wheel 10. The presser-plates 5 are connected to the thrust member 14 by bars 11, having pivotal connection at the point of meeting 13, so that rearward thrust applied to the thrust member tends to straighten the stretcher-bar, this action being permitted by the spigot 8a of the screw 8 sliding outwards within the tubular part 7a of the bar 7. The thrust member consists of an hydraulic cylinder 14 fitted with a ram 15 which acts upon the rear of the cutter shaft 16, the ram being actuated by a pump 17 driven by the machine and connected to the cylinder by a flexible pipe 18. An alternative construction of the thrust member has a nut 19, Fig. 5, through which passes a spindle 20 which, at its front end, carries a universal coupling 21 connected with the rear end of the cutter shaft 16 ; hence rotation of the cutter shaft causes longitudinal movement of the cutter. After each forward movement of the feed device, that is, the ram 15 on the screwed spindle 20, the stretcher-bar is slackened to allow withdrawal of the plates 5 from the sides of the tunnel and the thrust member &c. are moved forward in the bore to a fresh position, this movement being facilitated by suspending the thrust member by chains 26 from a small carriage 27 movable along a longitudinal runway 28 attached to the rear of the machine.

Abstract: 604,424. Aircraft guns. NASH, A. F. Oct. 25, 1934, No. 30648. [Classes 92 (i) and 92 (ii)] [Also in Group XXIX]' A plurality of guns 6, remote from the gunner in an aircraft, and the sighting device 3 are moved in unison by hydraulic servo-mechanism (see Group XXIX) under the control of a handgrip 13 which is mounted on a control column 12. Rocking of the handgrip produces an axial movement of a rod within the column and such movement is transmitted by bell cranks 14, 15, to the control rod 16 of the valve of the servo-mechanism. The arrangement is such that an appropriate movement is imparted to a crosshead 18 connected to the pistons of three cylinders 19, 20, 21, thus causing the flow of liquid in pipes 22, 24, 25 to actuate pistons in cylinders 23, 26, 27, causing the required elevating movements to be imparted to the guns and the sight. Similar means are provided as shown to train the guns and sight when the handgrip is moved about the axis of the column. In Fig. 3 (not shown) is an arrangement whereby one of two handgrips can be swung to open or close a master valve of the hydraulic system, this valve being connected also to the valves in the firing circuits of four guns, the valves functioning so that firing is interrupted on any one gun when jammed. The Provisional Specification describes also an arrangement in which the movements imparted to the guns is such that all the guns concentrate on the target.
