Abstract: 343,514. Nailing machines. WURSTER, F., 32, Tubingerstrasse, DIETZ, H. and DIETZ, P., 45, Waldhornlestrasse, both in Derendingen, Wurtemberg, and DIETZ, P., 30, Kurfurstenstrasse, Munich, both in Germany, (trading as WURSTER & DIETZ). Nov. 20, 1929, No. 35433. [Class 89 (iii).] Relates to machines for cutting from strip. and inserting, corrugated nails for connecting together two or more planks, of the kind comprising a driver head which is lowered by an eccentric to engage and clamp the planks, and a driver which is reciprocated through the head by an independent eccentric ; and consists in the provision of means for securing a uniform driving stroke of the driver when the planks to be connected are of unequal thickness. As shown, the connecting-rod between the driver head 9 and its operating eccentric 3 comprises crossheads 4, 7 connected respectively to the eccentric and the driver head. The crosshead 7 is slidable on guides 5 secured to the crosshead 4, a spring 6 being interposed between the crossheads. Nuts 19 on the guides allow of adjustment. Thus, when the head 9 moves down and engages a plank 16 of abnormal thickness, the spring 6 yields. This allows the driver 13 operated by the eccentric 11 to make its full normal working stroke, so that its lower end 14 partially penetrates the thicker board, causing the corrugated nail 15 to be fully driven into the thinner board 17, Fig. 5.

Abstract: 1,040,924. Jaw crushers. ROBEY & CO. Ltd. and A. CROMPTON. Sept. 28,1962 [Oct. 2,1961], No. 35486/61. Heading B2A. The movable jaw 4 of a jaw crusher is supported by a carriage 6 movable rectilinearly along guide means 8 towards and away from a fixed jaw 3, the reciprocating motion being effected by at least one piston and cylinder assembly 12 which is disposed with its thrust line in alignment with the direction of jaw motion and reacts directly against the crusher frame. As shown in Fig. 2, the carriage has a cylindrical portion 7 which is axially slidable on bearings 9 within a casing 8. Single-acting hydraulic piston and cylinder assemblies 12 are mounted on a back-plate 10 to effect the crushing stroke of the jaw 4, the return stroke being effected by action of a rod 15 and compression spring. Hydraulic fluid to the assemblies is supplied from a continuously-running pump through control valves operated by pilot valves which are tripped when the jaw reaches each end of its stroke; adjustment of the stroke may be effected by altering the position of trip. Flow-restriction means may be provided in the hydraulic system for controlling the rate of jaw movement. The jaw pressure is limited by means of a relief valve and, if desired, several relief valves may be employed each set at a different pressure and arranged in the hydraulic system so that any selected one can be brought into operation at a time. Instead of using relief valves to control the pressure, an accumulator may be employed. A modification, Fig. 4, shows the movable jaw 25 supported by a carriage 26 slidable in guide bushes 27, 28 on the frame. The crushing stroke of the jaw in this case is effected by the action of springs 32 and the return stroke by piston and cylinder assemblies 35 mounted on a back-plate 31. If desired, singleacting piston and cylinder assemblies may be mounted between the back-plate 31 and carriage 26 so as to assist the action of the springs; with this arrangement the hydraulic power necessary for the crushing stroke can be arranged to be the same as that for the return stroke. Alternatively, the assemblies may be double-acting so that the crushing stroke is effected jointly by the assemblies and springs 32.

An hydraulically-operated car-door latch includes a 3-armed pivotally-mounted bolt 5 which holds an hydraulically-operated ram 15 in a dead-centre position until a limb 47 of the said bolt 5 is tripped by contact with a striking plate 43 with which it then becomes latched owing to the compressive force in the ram 15. The latch is released by either the pressing of a button 4 in the outside door-handle or by a lever 30 on the inside of the door, either of which tilts a control member 27 about its pivotal point 28 to switch the control valve 21 to suction so that the bolt 5 is drawn back, assisted by spring 9, to the dead-centre position, shown in Fig. 1. Release of button 4 or lever 30 also causes control member 27 to return to the position shown under the influence of a spring 29 so that valve 21 is switched to compression ready to be latched again, the spring 9 in the meantime holding bolt 5 in the deadcentre position. In the event of failure of the hydraulic system the door may be slammed shut so that the bolt 5 still becomes latched by a spring-loaded detent 25 engaging a notch 38 in the bolt 5.
