Title: Improvements in register mechanism for sheet feeding arrangements
IPC: B65H9/10
Filed: 1946-11-11
Abstract: 622,686. Feeding sheets. HOE & CO., Ltd., R., and BATTEY, A. P. Nov. 11, 1946, No. 33456. [Class 100 (i)] Sheet register mechanism comprises a sheet impelling member and a driving component operated intermittently in step with the sheet feed to impart to the impelling member both an impelling movement and a movement into sheet-engaging position. Sheets are fed over a feed board and over a plate 21 in a recess therein and are gripped between an impelling roller 2 and an idle roller 6 and moved transversely against a side lay 5. The roller 2 is driven from an intermittently rotated shaft 14 through skew gears 13, 12 and gears 10, 9, 8, the gear 10 being mounted on a spindle 4 on which a U-member 3 carrying the spindle 7 of the roller 2 is mounted. The gear 9 is mounted on a spindle 9<SP>1</SP> which also carries a cam 15 co-operating with a follower 16, whereby rotation of the gear 10 drives the roller 2 while also lowering it into sheet-engaging position. The cam and follower are kept in contact by an adjustable spring 15<SP>1</SP> which regulates the maximum pressure of the rollers against a sheet, which is also controlled by a counterspring 17. A guide shoe 22 for the sheets is pivoted at 24 and raised by the spindle 7 to allow entry of a sheet, its lowermost position being controlled by an abutment 27 on a member 28 pivoted at 29 and adjusted by a screw 30 with which it is kept in contact by a torsion spring 32. A smoother plate for sheets fed into the apparatus is provided, pivoted on the frame 11 supporting the spindle 4. The frame is adjustable transversely of the feed along the shaft 14 and a tube to which it is releasably clamped, and is adjustable longitudinally by adjusting the latter tube. Instead of the roller 6 a plate mounted for free sliding movement on rollers and located in an opening in the feedboard may be used, and may be spring-actuated for return movement or mechanically returned by a connection with the U-member 3.

Title: Improvements relating to clutch mechanisms
IPC: F16D13/12
Filed: 1957-10-30
Abstract: 867,335. Operating clutches. KOEHRING CO. Oct. 30, 1957 [Oct. 30, 1956], No. 33899/57. Class 80 (2). An internal expanding clutch band 1, Figs. 1 and 2, adapted to engage a driven clutch drum 2 of, for example, a cable drum, is carried by a spider 7 secured to a hub 8 splined to a driving- shaft 4. The band 1 is anchored to the spider 7 at one end 9 whilst the other end is actuated by a lever 12 and a toggle 14 having a compensator spring 18 to compensate for expansion or contraction of the clutch drum 2 due to variations in operating temperature. The toggle 14 is adapted to be actuated to engage the clutch by relative rotation of a drum 29 to the frame 7 against a spring 51 by the application of an external brake band 32, Figs. 2 and 4, thereto. The band 32 is anchored at one end 33 to a stationary frame 34 whilst the other end 37 is coupled to the forked end 41 of a differential lever 42, the other end 57 of which is supported by a shift-fork member 52. Intermediate its ends the lever 42 is coupled by a pin 28 to a lever 24 connected by a linkage 22 to a manual control lever 21. The fork member 52 is pivoted at 53 and engages in a peripheral groove in a sleeve 62 axially slidable on the driving-shaft 4. The sleeve 62 carries a cam follower 63 cooperating with an arcuate cam 67 carried by the drum 29 so that on initial operation of the control lever 21 both ends 41, 57 of differential lever 42 move upwards to apply the brake band 32 and to move, through fork 52, the cam follower 63 against the cam 67. The braking of the drum 29 by bond 32 effects an angular displacement relative to the driving-shaft and spider 7 to operate the toggle 14 by a link 47 to apply the clutch band 1 to the drum 2. The relative movement of drum 29 allows cam follower 63 to move and operate fork 52 to raise the end 57 of differential lever 42 to tend to release the brake band 32 and provide a feed-back movement to the control lever 21. The lever 21 has to be moved further to obtain a further degree of clutch engagement. The clutch can be locked in a position of full engagement by the cam follower 63 engaging behind the end 69 of cam 67. Reverse movement of the control lever will release the cam follower and progressively release the brake band 32 until the clutch is fully disengaged.

Filed: 1932-12-05
Abstract: 411,480. Inductances. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 5, 1932, No. 34458. Convention date, Dec. 12, 1931. [Class 37.] In the production of compressed cores of finely distributed magnetizable powder, e.g. for Pupin coils, the powder is mixed with insulating material and compressed into the form of a core without the use of a binding medium and the compressed core is thereafter impregnated, preferably with heating and in vacuo, with substances such as oils, fats or waxes, which increase the insulation but not the strength of the core. To facilitate the pressing and the impregnation, small quantities of oil may be incorporated before the pressing operation. The powder may be of iron or of nickel-iron or other magnetizable alloys requiring a heat treatment, the final impregnation being necessarily subsequent to any such heat treatment. In an example, 100 parts by weight of iron powder are mixed with not more than ¥ parts of an insulating mixture, e.g. with 2/3 parts of a mixture of equal amounts of solid water glass and talc ; the whole is then subjected to a pressure of 14000 atmospheres without the use of a binder (cf. Specification 103,188, [Class 37]) and finally impregnated in vacuo with petroleum jelly made thin by heating. Stearin, paraffin wax and beef tallow are also specified as impregnating agents.
