Title: Improvements in or relating to drilling or like machines
IPC: B23B47/20
Filed: 1947-09-24
Abstract: 636,268. Drilling-machines. ARTHUR, E. M. Sept. 24, 1947, No. 25901. [Class 83 (iii)] A machine for drilling or rotary cutting operations comprises a spring device for applying pressure to the tool spindle 13 for automatically feeding the tool during the cutting operation, means for rendering the spring device inoperative, and manual means for feeding and returning the tool when the spring device is inoperative. The spring device shown in Fig. 2 comprises a leaf-spring 1 adjustably mounted in a rocker 2 which is pivoted to an extension 4 of the machine post 5. A lever 8 attached to the rocker 2 is connected by a link 9 to a hand lever 10 which is depressed to actuate the rocker 2 and cause the spring 1 to deflect and exert a force on a member 6 which is adjustably secured to the spindle 13. The deflected spring 1 feeds the tool until a hand-feed lever 14, which is rotated from the tool spindle 13 by a rack-and-pinion, releases the pressure on the leaf-spring-1 by displacing the lever 10 which is then returned to the raised position by a spring 23 acting on the free end of the leaf-spring 1. The pressure exerted by the leaf-spring 1 may be altered by varying the position of the member 6, adjusting screws 12 in the rocker 2, or by sliding the leaves of the spring in the rocker 4 towards or away from the tool spindle 13. In a modification, Fig. 3, the leaf-spring 18 applies pressure to the tool spindle 13 (not shown) through the hand-lever shaft 15, the spring 18 being connected to a chain 20 which passes over a chain-wheel 16 clutched to the shaft 15 and is connected to a helical spring 17. The spring 18 is anchored to a foot lever 19 which, when depressed, moves the spindle 13 downwardly and causes the spring 18 to apply pressure thereto. When depressed, the lever 19 engages a catch on a pivoted link 22; it is automatically disengaged therefrom at the end of the cutting operation by the spring 18 which trips the link 22 so that the lever 19 and tool spindle are then raised by the spring 17. By de-clutching the chain-wheel 16, the shaft 15 may be operated by hand. At the end of the cutting operation, the tool may dip into a container of cutting oil.

Abstract: 278,739. Soc. Anon. Fonderia del Pignone. Oct. 8, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Mines, marine. - Relates to mines connected in pairs by a horizontal cable which when encountered by a passing ship causes the mines to swing in and explode against the ship. According to the invention, the explosion is brought about a given time after the ship encounters the cable, determined by a dashpot or a screw propeller. As shown in Fig. 7, the mines c, d are connected together by a cable b attached to spring plungers 17, 17<1> intended to close switches 16, 16<1> when the mines are laid to set towing propellers in action. Each mine is provided with a small screw propeller 7 on a screw spindle 8 in engagement with a sliding nut 10 carrying a firing pin 11. When a passing ship drags the cable b, the propeller 7 is caused to rotate and draws the nut 10 against a spring 12, until the nut reaches the point 14, when it is freed from the spindle 8 and is thrust by the spring 12 against a percussion cap 15. In a modification, Fig. 5, the cable connecting the mines is attached to a bolt t connected to a dashpot piston k and to a firing pin u. After a given travel of the dashpot piston k, a joint s is freed, and the firing pin is thrust against the percussion cap v by a spring m. Projections x, w constitute the switch which is closed when the mines are laid, or a switch controlled by a separate spring is provided for this purpose. In other modifications, the firing is performed by the closing of the circuit of an electric igniter.
