Title: A new or improved paste feeding device
IPC: B65H37/02
Filed: 1934-04-03
Abstract: 436,223. Reciprocating pumps. LOUGEE, F. G., and PATTINSON, T. E., 109, Borough Road, London. April 3,1934, No. 10115. [Class 102 (i)] [See also Groups XVI and VIII] A pump for forcing paste to a nozzle block which applies a line of paste to a web coming from a pointing machine, comprises a block 30 which carries four plungers 26, is journalled to the central eccentric portions of crankshafts 36, and is capable of sliding vertically on guides 31 rigidly fixed to a member 27 constrained by guides to slide horizontally. The crank-shafts 36, are journalled at their ends in the pump casing 29, and on their being revolved by gears 39, 40, the block 30 moves in a closed loop, the horizontal component being transmitted to the member 27, and the vertical component to the plungers 26. Thus, as the plungers 26 rise, the block 27 moves to the left so that bores 27<1> formed therein, register with supply grooves 43 communicating with the interior of the casing (which forms a paste sump), and are filled with paste. As the plungers descend, the block moves to the right, so that the bores 27<1>, register with, and discharge into, passages 42, connected with the nozzles. The feed from any plunger can be reduced or cut off, by screwing down a stop 65. The end of the plunger will contact with this, further upward movement of the block 30, merely compressing a spring 34. The sump is filled through spout 46, and drained through pipe 49. The pump is driven from shaft 58 through a chain 56 and gears 52, 51. The gear 51 may be freed on its shaft by operating a clutch 61, and the pump rotated by a handle 60,

Abstract: 876,194. Stuffing-box substitutes. DONLEY PRODUCTS Inc. March 23, 1960, No. 10287/60. Class 122 (5). A shaft or bearing race sealing assembly comprises two oppositely-directed bearing rings 21, 35, Fig. 1, which have flat bearing surfaces and are supported in spaced relation to each other, with the said bearing surfaces in contact with the surface to be sealed, upon flanges 27, 42 on two metal annular leaf springs 22, 36 which have opposed flanges 32, 46 for mounting the springs in position. The flanges 27, 42 on the springs 22, 36 provide conical seating surfaces for the bearing rings 21, 35 of such inclination that the bearing rings can be secured to them by a press fit. The sealing units can be press fitted into the outer race 15 of a bearing when the portions 28, 43 of the springs, which in the free state are at about an angle of 10 degrees to the plane of the springs 22, 36, become perpendicular to the axis of the shaft. The main portion of each of the springs 22, 36 comprises an outer bowed portion facing either inwardly or outwardly of the seal. The springs may be of stainless steel, brass, or suitable alloys. The bearing rings may be of a metal, ceramic, rubber or plastics material or of carbon impregnated with a metallic infusion and their bearing surfaces are lap finished and may be coated with a dry-film lubricant 38, which may be molybdenum disulphide; furthermore, the bearing rings may be provided with axial bores 37 to allow the circulating of air near the bearing surfaces. The bearing rings may, alternatively, be carried at the outer peripheries of the springs and the mounting flanges provided on the inner peripheries adjacent the shaft. When used as a shaft seal operating between a stationary element 51, Fig. 5, and a movable element 52, such as a collet housing or hub of a pump, the interfitting flanges 74, 75 can be welded together or they may be of corresponding frusto-conical shapes enabling them to be rightly press-fitted together. In the construction shown in Fig. 11, the interengaging flanges 111, 112 are of tapered form on the inner peripheries of the springs and are press-fitted together, and the outer flanges 121, 122 provide cylindrical bearing surfaces for the bearing rings 106, 107. A further arrangement for a shaft 130, Fig. 14, surrounded by stationary and rotatable elements 131, 132 comprises two seal units 134, 135 telescoped together by the tapered flanges 136 and comprising leaf springs 137, 138, bearing rings 139, 140 and reversely-flanged elements 141, 142.

The beam 1 is reciprocated by a connecting rod 5 from a crankshaft 22 and the perforated table 15 is supported on links 16, 17 and is guided vertically between posts 26. The table is oscillated by a link 28 pivoted to the table and to the beam, the latter connection being a slot 24 which may have a spring inserted therein. The oscillating motion of the table may be varied. by moving the point of connection of the links 16, 17 with the base 25 by means of screws 18 and the table may be spring-supported. The table may be actuated by cams which hold the table stationary during impact of the picks. A conveyer belt 27 under the table 15 removes the broken material. The picks 6 ... 9 are each provided with a flanged collar retained against the pick head between two perforated plates.

IPC: F41A9/10
Filed: 1918-06-27
Abstract: 131,404. Schneider et Cie. Aug. 16, 1917, [Convention date]. Loading-appliances.-Consists of hand loading- gear for heavy ordnance, comprising a swinging arm carrying a scoop and pivoted in such a way that a continuous movement of the arm raises the scoop from the receiving-position to the loading- position. The scoop is fixed at the end of the arm which is pivoted to a part of the gun carriage which participates in the training movement. In the construction shown in Fig. 2, the footstep bearing B is inclined, and the arm E carrying the scoop D extends at an angle a from the pivot U, so that the scoop is raised from the receiving position shown in dotted lines to the loading position by a continuous rotation through 180 degrees. Ratchet gear is provided to prevent accidental return movement nf the arm. In the modification shown in Figs. 5, 6, and 12, the footstep bearing B is vertical and the arm 1, J carrying the scoop D is pivoted on a horizontal pivot K to a bracket I, carried by the vertical pivot C. A rope M is attached at one end to the arm J and at the other end to an eye B' on the footstep bearing, so that when the arm I, J is turned about its bearing in the footstep, it is also turned about the horizontal pivot K by reason of the rope M becoming wound on the footstep bearing. The two parts I, J of the loading arm are pivoted together by a pin j but rotation of the arm I about the pivot j is prevented by the cheeks L<1> of the bracket L, except in the highest position of the scoop shown in Figs. 5 and 6. In this position, the arm I is raised above the cheeks L<1> and is free to be rotated about the pivot W complete the loading movement.
