Title: Improvements in or relating to machines for grinding rolls and the like
IPC: B24B7/16
Filed: 1930-01-13
Abstract: 350,921. Grinding. CINCINNATI GRINDERS, Inc., 3058, South Street, Cincinnati, Ohio, U.S.A.-(Assignees of Booth, C. and Binns, G. W. ; 3555, Edwards Road, Cincinnati, Ohio, U.S.A.) Jan. 13, 1930, No. 1196. Convention date, Jan. 22, 1929. [Class 60.] Rollers and the like, treating; spindle mountings.-A machine for grinding the ends of rolls &c. consists of a bed 25 having ways 26 upon which are adjustably mounted a slide 27 carrying upon a vertical spindle a work rotating disc 46, and a slide 28 carrying upon a vertical spindle a disc 42, the spindles being driven, through worm gearing, from a main shaft. The peripheries of the discs are shaped to engage the rolls 44, shown as of frusto-conical form, and to prevent axial movement thereof in one direction, and the periphery of the disc 42 is notched at 45 to allow of ejection, to a shoot 75, of finished work pieces by a spring-pressed plunger 72 on the disc 46. In the disc 46 is a radial groove or slot 48 for a plunger 49 movable by a spring-pressed lever 53 pivoted in an aperture 55 in the disc and carrying a roller 57 engaging a cam 58 pivoted at 59, below the disc, to a plate on the slide 27. The cam is pulled by an adjustable spring 62 to an extent limited by a stop screw 66 so that, as the disc 46 rotates to bring the slot 48 towards the grinding position and a work piece is placed in the outer end of the slot, the cam will move the lever 53 to press the work against a guide-plate 68. Continued movement rocks the cam and tensions the spring 62 until the bevelled end 69 of the plate is reached, when the pressure of the cam against the lever snaps the plunger 49 outwards to press the work into the space between the discs, where it is rotated; movement of the work is restrained by a work-rest 70. The work is ground by a grinding-wheel 85 mounted on a spindle 78 in a slide 77 adjustable, by a screw 80 and worm gearing, on a column 76, and the wheel is reciprocated axially by a sleeve 86 slidable but not rotatable in the slide 77 and engaging the spindle 78 by an antifriction bearing 87. The sleeve is pivoted at 98 to a lever 89 having an adjustable pivot 91 carried by a lever 92 and engaging a slot 90 in the lever, whereby the extent of reciprocation of the wheel 85 may be adjusted, and the lever is oscillated by a lever 95 moved by rack and pinion gearing 103 by a slide bar 101 actuated by a cam 99 and a spring 102 ; the oscillation may be stopped by locking the bar in its innermost position by a screw 123. The periphery of the wheel 85 may be shaped as shown in Fig. 12 or otherwise, to grind bevelled, half round, or other ends on the rolls. The work engaging peripheries of the discs 42, 46 are trued by a turning-tool 116, Fig. 11, adjustable by a screw 114 in a sleeve 111 adjustably pivoted to a slide 109 adjustable on a bracket 106, which may be secured to either of the slides 27, 28. The discs 46, 42 may be of different sizes and may have different surface speeds ; the member 68 may be omitted.

Title: Improvements in or relating to absorption refrigerating systems
IPC: F25B15/10
Filed: 1928-01-20
Abstract: 283,937. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System Aktiebolag). Jan. 20, 1927, [Convention date]. Refrigerating, absorption machines for. - In continuous-cycle systems having the parts in open communication with one another, a circulation of the liquor between the absorber A and the generator O is effected by a suction action produced in a condenser K of the system during the time it is sealed off by liquid seals. This lifting action may be assisted by the superior pressure in the generator. A pipe B leads from the bottom of the generator to the condenser and is provided in its upper part with baffles 11 to form a rectifier V. It communicates with the gas space of the ganerator by a bent sealing-pipe X, and with a vessel S by a pipe 6. The vessel S connects by a pipe 7 with the rectifier and is thus always at the pressure of the condenser. Strong liquor flows from the absorber to the gererator through a pipe 2 forming an interchanger P with a pipe 1 for conveying weak liquor from the vessel S to the upper part of the absorber. The, rectifier is surrounded by a cooling-jacket fed by a pipe 13 with liquefied refrigerant, as described in Specification 274,840, collected in a separator T located between the condenser and the evaporator G. A pipe 3 connects the upper part of the rectifier jacket' with the gas space of the condenser. Liquid passes from the separator T through a U-tube 5 to the top of the evaporator and a vent pipe 4 for the hydrogen or other inert gas circulating between evaporator and absorber extends from the separator to the bottom of the absorber. The action of the arrangement is such that liquid rises from the generator through the pipe B while the pipe X is sealed, and flows into the vessel S by the pipe 6 and then by gravity through the pipe 1 to the absorber. Eventually the liquid seal in the pipe X breaks and gas passes into the pipe B to the condenser and equalizes the pressure, whereupon the original liquid levels are restored. The arrangement may be adapted to raise strong liquor from the absorber to a level above the generator and the pipe 6 may extend from the liquor space of the generator to the vessel S. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the utilization of periodical alteration of the concentration in the generator to seal the gas passage to the condenser. This subject-matter does not appear in the Specificaton as accepted.
