Title: Improvements in or relating to Overrun-preventing Mechanism for Calculating and like Machines.
Inventor: BANNEHR LEONARD WILLIAM
Filed: 1912-05-09
Granted: 1913-08-11
Abstract: 10,015. Bannehr, L. W., Dolton, J. H., Gilbert, J. B., and Watson, G. May 9, 1912. Summing and subtracting positive and negative items; overthrow-preventing mechanism.- In machines for adding gross and tare weights and subtracting the one from the other to obtain and total the net weights, of the type described in Specifications 4872/08, 4874/08, and 11,076/12, the setting-members for the net department may be displaced in either direction from normal position, and stop - mechanism is provided so that, on resetting the net setting- members, they will be arrested at zero whichever may be the direction of rotation. Wheels 32, Fig. 2, permanently in gear with the setting- members, are provided with a pin 33, which, upon resetting, is arrested by the flattened end of one of the two spring pawls 34, 35, mounted upon a pivoted frame 36. In the normal position shown, these pawls are inoperative, but when the machine is operated, subsequently to the setting of an item, a shaft 3 is given a rotation clockwise, whereby a cam 49 thereon slides a slotted bar 48 to the right and depresses a cross-bar 43 carried by bent levers. Through a link 42 secured to the cross-bar, sufficient tension is thus given to a spring 41 to rock the frame 36 against the action of its normal retaining-spring, and so to bring the pawls into the path of the pin. After the resetting movement has been effected through suitable connexions (not described) from the main operating-mechanism, an anticlockwise rotation is similarly communicated to a shaft 2 carrying a lug 53, which restores the slide and thereby allows the pawls to withdraw to normal position.

Inventor: HARWOOD ALFRED
IPC: B60R21/34
Filed: 1914-02-26
Granted: 1915-03-26
Abstract: 4956. Harwood, A. Feb. 26. Wheel-guards and obstruction-removers. - A bracket secured to the stub axle of each front wheel of a motor-vehicle carries a fulcrum for a lever C which at its lower end carries a guard and brake-wheel O, and at its upper end is connected by a ball- and-socket joint disposed vertically above the steering pivot to a rod Jb connected to mechanism for declutching the motor when an obstruction is met. Each bracket is made adjustable in length by forming it in two portions M, M<1> with serrated faces clamped together. Each lever C carries a support Fa for a guard-plate F disposed in front of the wheel, and the two levers C are connected by a rod G which carries a guard H to cover the space between the wheels. Each rod Jb is connected through a rod Ja to a rod J secured to a hollow quadrant Q freely mounted on the clutch rod N, and a rod K secured to the opposite side of the quadrant extends towards the rear of the vehicle and is pivoted to a lever Fb which is fulcrumed on a bracket fixed to the chassis and carries a guardplate F<2> and a guard and brake wheel B02 for the rear wheel. The rods J, Jb are each adjustably connected to the rod Ja by a jointpiece shown in Fig. 7, having sockets to receive the ends of the rods which are clamped in position by key-pieces J2 and set-screws J3. Within one of the quadrants Q is a pawl Qf keyed to the clutch rod N so that when the quadrant is operated by the pressure of an obstruction against one or more of the guard wheels or plates or against the guard H, the pawl is actuated to declutch the motor. Hatchet teeth in the top of the quadrant are engaged by a spring-pressed plunger Qa to lock the quadrant in the declutching position until the plunger is drawn up by the driver, whereupon the quadrant is returned to normal position by gravity or spring action. The construction of the guard-wheel 0 is shown in Fig. 6. The body Oa is of vulcanized fibre rotatably and slidably mounted on a short spindle Of secured to the lever C, and a spring Od is disposed between the enlarged end 0/1 of the spindle and a steel cap Oe fixed to the outer side of the wheel, so that when a kerb is encountered, the wheel slides along the spindle against the action of the spring. The wheel is fitted with rubber tyres Ob, and wear is compensated for by an adjustment of the spindle Of in a slot in the lever C. The guards described in Specifications 22,800/11, 29,258/11, and 1801/13 are referred to.

Title: Improvements in or relating to Sheet or Plate Delivery Mechanism.
Inventor: BOOTH JOSEPH BOURDAS SMITH
IPC: B65H33/04
Filed: 1914-03-16
Granted: 1915-03-16
Abstract: 6590. Booth, J. B. S. March 16. Delivery apparatus; sheet-separators. - Relates to a delivery mechanism for rigid or semi-rigid plates, sheets, or cards, and is particularly applicable to delivering plates for separating counted batches of sheets delivered from a printing - machine. The separating-plates A are carried in a magazine B with their lower ends slidably engaging an inclined guide-rail C. The upper ends of the plates are provided with upstanding portions engaged by a retaining-catch F' which is reciprocated by a link F<2> and lever F. Successive plates have their upstanding portions on opposite sides of the centre, so that the catch F<1>, at each movement, releases the front plate to allow it to fall and engage the upstanding portion of the next plate to retain it Pins f, f<1> on the lever F on opposite sides of its pivot are alternately engaged by arms G<1>, G'' pivoted to a member G which is pivoted to a reciprocating driving-member D, which receives a quick driving-stroke by means of a spring D<1> and a slow return stroke by. means of a snail-cam H<1> and projection d on the member D. The arms G<1>, G<2> are connected by a link G<3> controlled by a spring G<4>, and the pivotal movement of the member G is limited by a projection g and slot. When the parts are in the position shown in Fig. 1, the next driving stroke of the member D moves the catch F' to the left by the engagement of the arm G<2> with the pin f<1>, and at the same time the member G is turned on its pivot to move the arm G<1> opposite to the pin f, so that the lever F is driven alternately by the arms G', G<2>. The cam H<1> is driven by a ratchet-wheel H and pawl J<1> carried by a member J, which is operated by linkage J<5>, J<4> from the printing- press. By using a ratchet-wheel H with a different number of teeth, or by altering the stroke of the pawl J<1> or the shape of the cam H<1>, the rate of delivery may be varied.

Title: Improvements in Internal Combustion Engines.
IPC: F01L13/00
Filed: 1914-04-25
Granted: 1915-04-26
Abstract: 10,272. Marks, E. C. R., [Harris Patents Co.]. April 25. S t a r t i n g ; reversing; stopping.-In an engine having cylinders each of two diameters, to the annular pump spaces of which compressed air is admitted for starting or to supplement, d u r i n g normal w o r k i n g, the power developed in the combustion cylinder, the admission of compressed air is controlled by a fluidactuated valve 22, which is shown in Fig. 5 as applied to one of the cylinders of a reversing engine having a pair of cylinders which are cross-connected. During normal working, air is drawn into each pump space through ports uncovered by the piston at the end of the outstroke. The air is delivered through ports 27, Fig. 5, and past an automatic valve 16, which is held to its seat by a spring 28, into a chamber 12 located adjacent terminal inlet ports in the walls of the combustion cylinders. Compressed air is admitted to each pump space through a valve 22, which is lifted by the inrushing air to out off communication between the pump cylinder and the chamber 12. The bulk of the compressed air is released when the pump pistons uncover terminal ports (not shown), the residual air being compressed and supplied to the combustion cylinders. Compressed air is conveyed to the conduit 23, Fig. 5, leading to the valve 22 through one or other of the passages 29, 30, in accordance with the direction of running. Each of the passages contains a valve 35, which rests normally upon a seat 34, but is forced on to a seat 34<a> when air is admitted to the passages 29, 30. The valves are depressed from their seats 34<a> by actuating cams (not shown), which engage rollers 38 on the valve stems. The supply of air to the pipes 29<a>, 30<a> is controlled'by valves 50, Fig. 8, the stems of which engage cams 55 under the control of a hand-lever 41. When the lever is moved into its first position on either side of its central inoperative position, one of the cams 55 opens its corresponding valve 50 to admit compressed air for starting, the combustion cylinders being inoperative. In, a second position of the lever, the air supply is cut off, and the fuel injection valves in the heads of the combustion cylinders become operative. To increase the power developed during normal working, the air valves 50 may be opened by a tappet 156 which engages pins 157 carried by the valve stems, the tappet being secured to a spindle 155 actuated by an auxiliary hand-lever 150 through a rack and pinion. The auxiliary lever may be used to start the engine independently of the lever 41. Compressed air for braking or stopping may be admitted on the up-strokes of the pistons by turning the auxiliary lever to operate the valves associated with. the opposite direction of running. When the engine is applied to a locomotive, the braking effect may be utilized to check the motion of a train. If it is desired to run the engine in one direction only, one set of valves 35, 50 may be dispensed with. Specifications 804/15 and 805/15 are referred to.
