Abstract: 902,689. Force-feed lubricating. SUNDERLAND, H. Oct. 5, 1960 [Oct. 6, 1959], No. 33847/59. Class 12 (3). In a device for lubricating shafts, the rocking of a pivoted track 17 effects the lubrication of a shaft located in guide-blocks 20, having lubrication holes 21 therein, and also effects the release of a previously lubricated shaft so that it can roll to an unloading position 27. The track 17 is pivoted between brackets 18 and is connected, via arms 15, 14, and a spring-loaded ram 13, to a piston (not shown) of a pump 12 so that, by rocking the track 17 by means of a handle 16 attached thereto, the pump is operated and lubricant is supplied to the shaft through holes 21 in the blocks 20. A releasable stop 26 is carried by a bracket 25 which, along with the brackets 18 &c. is mounted on a reservoir 11. In use, shafts are fed down an inclined track 28 until the first shaft abuts the stop 26 and consequently the second shaft is in alignment with the blocks 20. On depressing the: handle 16 to effect lubrication of the second shaft, the first shaft is released from the stop 26 and rolls to the unloading position 27, and-the blocks 20, being connected by bars 19 to the track 17, are raised so as to retain the second shaft during lubrication thereof. On releasing the handle 16, the spring-loaded ram 13 effects the lowering of the blocks 20 so that the second shaft is free to roll into abutment with the stop 26. At this stage a third shaft from the feed-track 28 is moved into alignment with the blocks 20 and the process is now continuous. The first shaft, having served the purpose of aligning the second shaft is loaded on to the feed-track 28.

Title: Improvements in or relating to the separation and feeding of sheets
IPC: B65H3/54
Filed: 1927-12-16
Abstract: 282,429. Spiess, G. Dec. 16, 1926, [Convention date]. Sheet-separators. - Relates to sheet-feeding devices of the kind in which the sheets are separated from a farmed-out pile 2 and the pile is acted on by a holding or pressing device 16 acting to hold the lower sheets while the uppermost sheet is drawn off and being raised periodically from the pile by means automatically regulated according to the varying height of the pile. According to the invention the devices for actuating the presser 16 are mounted in a frame 3 arranged laterally of the pile table 1, so as not to prevent access to the pile and sheet-feeding, devices, and the presser 16 is arranged to be permanently in contact with the pile when the sheet-feeding devices are put out of operation. The presser 16 is adjustable about a vertical pivot 15 in an arm fitted with an eyelet 14 which is adjustable on a rod 7 carried by members 6, 8 pivoted to lever arms 5, 9, connected by lever arms 17, 19 and a link 18. The presser 16 is raised and lowered by actuating the lever 5, 19 by means of lever-and-link 21, 22, 23, 25 connected to the hub of lerver 5, 9 by a sleeve 20, the mechanism being mounted mainly in the frame 3 and laterally of the pile. The presser 16 normally rests on the pile by gravity, and the lever 25 is fitted with a ratchet 26 which is engaged by a pawl 27 on the spring- controlled lever arm 23 oscillated by a cam 37. As the arm 28 moves outwards it raises the presser 16 to an extend which is independent of the depth of pile below the presser. As the arm 28 returns, the link-system controlling the presser moves by gravity until the presser touches the pile. The pawl 27 can slide over the teeth 26 if necessary, and in any case the pawl is disengaged from the teeth by a roller 34 when the arm 8 reaches a predetermined position. When the feed mechanism is tripped, a cam 38 is operated and acts on a lever arm 36 integral with lever arm 28 to raise the arm 28 away from its cam 31, and the presser is maintained in contact with the pile. The pawl 27 is at the same time disengaged from the ratchet 26 by means of a projection 43 integral with cam 38 which acts on a rod connected to pawl 27. Or the pawl may be disengaged by contact of a curved surface on its upper end with a fixed pin arranged on a fixed arm above the upper position of arm 28.

IPC: G02B27/12
Abstract: 341,078. Colour photography and kinematography. PRISNER, S., Mowbray Road, Kilburn, London. Oct. 7, 1929, No. 30407. [Classes 97 (i) and 98 (ii).] The light reflected from an object illuminated with white light is concentrated into a very narrow parallel beam and is divided up into a spectrum which is recorded on a photographic layer. Optical reproduction is effected by splitting up a parallel beam of white light as when taking a photograph, passing it through the photographic image and bringing the separate colours back into a single beam. In the form shown light from the object 2 is concentrated into a narrow parallel beam by lens 1, 3, divided by the prism 4, and falls on the photographic film 5. When reproducing, white light is concentrated into a narrow parallel beam and divided as when taking the photograph and caused to pass through the negative or a diapositive made therefrom, the divided and modulated light being then recomposed by a further prism and projected on a screen. In a modification it is stated that the prism 4 may be replaced by a number of similar but smaller prisms in the form of a glass grating, the number of systems of concentrating lenses being similarly increased so that each element of the grating receives a separate narrowed band of light.
