Filed: 1920-05-18
Abstract: 143,546. Bayrer, W. J. Dec. 18, 1916, [Convention date]. Drilling-machines; attachments for drilling. - In a belt-driven pillar drilling-machine, means are provided for rapidly adjusting the position of the guide-pulleys 98, 99, according to the belt tension desired and to the portion of the stepped cone pulley 12 it is desired to use. The pulley 98 is carried by a frame 105 pivoted between round-headed pins 100 on a slide 97, which also has a race to support the rollers 111 on the front of the bracket 105. The pulley 99 is carried by a bracket 116 pivoted vertically on the slide 97 and clamped in adjusted position by a set-screw. The slide 97 is adjusted on the support 24 by a rack 143 and pinion 142 actuated by a worm-wheel and worm 144, which may be rotated by a hand-wheel 154, or may move axially, against the pressure of a spring 151, to an extent limited by a collar 150, and a stop 161, which engages a stop 160 to prevent further rotation of the worm when the spring 151 is compressed to give the maximum desirable belt tension. The support 24 is adjusted vertically by rack and pinion operated by a handle 85, and so proportioned that each complete revolution of the handle shifts the support 24 a distance equal to the width of one 'step on the pulley 12, where it is then held. by a spring-controlled releasable stop 90. The weight of the spindle and sleeve 13 is counterbalanced by a weight 15 on a chain 16. The Specification as open to inspection under Sect. 91 (3) (a) describes also a high speed supplemental tool carrier, Fig. 1, driven by belts from a pulley on the spindle 14 through a parallel lay shaft. The positions of the guide pulley support 24 are indicated by a pointer co-operating with an index plate. A belt shifting device comprising a ring 173 and adjustable yoke 174, Fig. 3 (Cancelled) is mounted on a rod 170 moved transversely by a link 191, crank 190, shaft 184, bevel pinion 188, and sector 187 on a shaft 179 carrying pedals 180 the sector and bevel pinion being kept in mesh by a slot 182 which also acts as a stop to determine the extreme positions of the belt movement. The spindle 14 is carried on ball bearings and springs mounted between the upper thrust bearing and a collar 38 eliminate end play. Flanged oil-retaining caps are provided for the ball bearings of the pulley 12, spindle 14, pulleys 98, 99, shaft 8, and the sleeves 220, 214 of the high speed attachment. This subject-matter is not described in the Specification as accepted.

Abstract: 514,777. Fluid - pressure servomotor - control systems. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H. May 9, 1938. No. 13734. [Class 135] A control mechanism for rudders, wing flaps and other control surfaces of aircraft comprises a control lever coupled at one end to a manually operable member and at the other to a pneumatic motor and the part under control. The lever has a hollow fulcrum surrounding a stationary pivot with a clearance sufficient to allow a limited displacement of the fulcrum which displacement is used to actuate the control valve of the motor. In the form shown in the Figure the device is shown applied to the operation of a wing flap 1 of the split trailing edge type. A single-acting spring-loaded piston 4 is coupled to the flap by a rod 6, crank arms on a rock shaft 8 and link 9 and is controlled by a valve 11. This valve controls the supply and exhaust of compressed air to and from the cylinder and is actuated by a crank arm 12 linked to a floating lever 17. This lever which has a hollow boss 14 encircling with lost motion the rock-shaft is connected on the one hand to the pin 16 coupling the rod 6 to the arm 7 and on the other is linked to a control handle 2. Fitted with a frictional or toothed locking device 3. In a modification the power device is made double-acting and is controlled by mechanically interconnected control valves. According to the Provisional Specification an auxiliary motor device under the same control may be coupled to the flap or the transmission near the flap.

Ruling - appliaraces - A machine for marking the edges of book signatures comprises means for holding the signatures in fixed position, a marker, and means for moving the marker transversely of the signa tures in contact therewith to mark them. The different signatures may be marked in different positions along the back edge so as to facilitate collating them, the marks on the several signatures of an assembled book presenting a diagonal line across the back. The signatures 7 are held in an oblique trough formed of end walls 8, a ledge 5, and bottom ledges 6, the latter providing an opening enabling the signature back edges to be marked by a marker such as a strip of inked felt 17 mounted underneath. The strip 17 is held by a bar 18 secured by screws 20 to a push. bar 21 provided with a handle 32 and formed with cam grooves 27, 28 engaging studs 24 on a carrying bar 22. By this means, pressure on the handle 32 first raises the marking strip 17 into contact with the signatures and then moves it across them to effect the marking. the parts being returned to their original position by a spring 29. The carrying bar 22 is mounted on a pair of racks 33 meshing with pinions 35 on a shaft 36 rotatable by means of a handle for moving the marker lengthwise of the signatures.

Abstract: 573,192. Washing-machines. BRITISH THOMSON-HOUSTON CO., Ltd., and COCKE, K. J. R. Sept. 1, 1943, No. 14247. [Class 138 (ii)] [Also in Group XXIII] A clothes washing machine of the kind having an agitator mounted on a driving shaft extending upwardly through the base of the tub is adapted to clean dishes and the like by replacing the agitator by a liquid distributing head which fits over and is driven by the hollow shaft 1 extending through the pedestal 3 secured to the bottom of the tub, as in the machine of Specification 512,503, the head comprising a central tub 9 carrying one or more pairs of upper and lower pipes 10, extending radially, ana having apertures 13 to direct jets downwards and upwards respectively on to the dishes &c. which are arranged in packs 16, removably placed on ledges 17 and formed to clear the pipes 10. The latter communicate with a passage 11 and a central dome 12 supplied through the hollow shaft 1 in which is located a fixed liquid supply pipe, leakage of liquid and pressure being prevented by a seal 15. The liquid may be circulated by a pump below the tub with intake at an outflow 18, an overflow 19 being provided as a short stand pipe inserted for dish washing in a drain outlet, which is normally plugged when the machine washes clothes. To prevent splashing the lid must be closed before the pump can be started for example by having a switch in the pump motor circuit closed by the shutting of the lid. To facilitate handling the racks 16, the shaft 1 can be disengaged from the motor drive for example by disengaging the rack and pinion oscillating gear as in Specification 512,504, [Group XXIV], where the position of the distributing head attached to the driving shaft can be altered by hand. To rinse the articles, cleansing liquid may be drained from the tub and rinsing liquid supplied and the pump started. Alternatively a pipe 20 may be arranged round the edge inside the tube with holes to spray liquid over the articles from a hot water supply or through the pump. A second pump may be fitted for this purpose.
