Abstract: 1,180,014. Controlling pedestrian-operated vehicles. ECCLES ENG. Ltd. 28 April, 1967 [14 April, 1966], No. 16326/66. Heading B7H. A drive control unit for an industrial truck or other pedestrian controlled vehicle comprises a frame 16 having a turntable whereby the frame may be rotatably mounted on the truck body, a motor 18 for driving a steerable wheel 17, a steering handle 20 mounted on the frame, and respective micro-switches 34, 36 mounted on the frame and actuated when the handle is in respective first and second positions to cause the motor 18 to drive the wheel 17 in corresponding first and second directions, the arrangement being such that when the handle is in an intermediate position neither switch is actuated and the wheel is not driven. The handle 20 is carried by a slide member 21 slidable on shafts 22 and urged into an intermediate position by springs 23. A cam plate 31 secured to an arm 28 on the slide member 21 carries adjustable dogs 33, 35 which actuate the micro-switches 34, 36 upon displacement of the slide member in the appropriate direction and thereby energize the motor 18. A cam surface 37 on the cam plate 31 engages a roller follower 38 on the plunger 39 of an hydraulic cylinder 40 which effects under dash-pot control the closure of carbon resistance discs incorporated in the motor circuit to determine the rate of acceleration of the truck. A spring- loaded brake plate which engages a friction disc to brake the motor 18 when the handle 20 is in its intermediate position is released by a solenoid when either micro-switch 34, 36 is closed. A head 25 pivotally attached to the handle 20 carries laterally-projecting hand grips, indicator lamps which show the selected direction and speed, and a key-operated switch arranged such that the motor circuit can only be energized when the handle 20 is in its intermediate position. The motor 18 drives the wheel 17 through chain reduction gearing 19.

[Class 102 (i).] A pump for a typebar-making machine is provided with one or with several pistons operated by a lever and spring or levers and springs, the lever or levers being provided with rollers which run one behind the other on the same cam, whereby in lifting the piston or pistons, the rollers in contact with the cam at any instant are acted upon by different parts of the cam, whereby the wear upon the cam is reduced. In Fig. 1, three pistons c are moved by three levers d, e, f each under the pressure of a spring g. Each lever carries a roller h, i, or k, which runs on a cam l, and on the pump lever e stops are provided which engage under the levers d and f and thus prevent the levers f, d and rollers k, h from falling into the recess of the cam before the roller i has passed the edge o. In lifting the levers, the rollers k, h, i are raised and the corresponding springs g are stretched, in turn. In Fig. 3, only one piston c, lever d and spring g are provided, and to the lever d is pivoted at r a carriage q carrying cam-rollers h, i, and such that in the raised position of the piston c it is pressed against the stop s on the lever d, and remains so pressed until the second roller i falls into the recess of the cam, when the carriage releases the stop s to permit the piston to descend. In raising the piston, the cam first acts upon both rollers in effecting the initial compression of the spring until the carriage engages the stop s, when it acts through the increased leverage resulting from the distance between the axes u, t, the roller h having run over the edge p.

Filed: 1923-07-04
Abstract: 212,810. Cadgene, E., and Dupont, G. July 4, 1923. Stencilling; inking-apparatus. - In a fabricprinting machine of the type wherein a thin flexible stencil is passed between a pair of pressure elements, the stencil is so supported as to allow it a limited lateral floating movement to permit it to adjust itself freely to working conditions. The machine shown includes a large pressure 'drum 14, mounted for vertical adjustment in the frame 10 and rotatable by suitable gearing, a stencil 23 mounted above it, and rolls 11, 13 for the web 12 to be printed. The stencil 23 is constructed of thin sheet metal, perforated to give the desired pattern, and formed as an endless, preferably cylindrical, surface, and is loosely mounted around a stationary drum 22 of smaller diameter clamped at its ends in separable members 19, 20 fixed to brackets 18. A pressure member 26 formed as a knife-edged blade within the drum is mounted by trunnions 28 in latch-members 31 laterally adjustable on the brackets 18, and is yieldingly pressed against the stencil 23 and drum 14 by weighted levers 36 fixed to the trunnions 28. In operation the drum 14 is rotated and the pressure between it and the member 26 causes the stencil to be rotated and the web 12 to be fed forward. As the stencil is rotated it will adjust itself to a perfect line contact with the edge of the element 26, as the result of its freedom of movement upon the drum 22, thereby ensuring an even feeding of the printing composition. The drum 22 may be replaced by one or more bars arranged inside or outside the stencil so as to limit its floating movement, and flanged collars 24 or ribs on the drum may be arranged to limit the area of contact of the drum and stencil floating movement of the latter. Means for feeding printing composition to the stencil include a trough 41 supplied by a pipe 38 having several outlets 39. The composition passes from the perforated bottom of the trough to a deflector plate 43.
