Abstract: 270,685. Bernat, R. May 5, 1926, [Convention date]. Mounting. - Relates to compressors and particularly those with gear driven rotary valves and consists in securing a machined face on the compressor casting to a facing on a casting carrying the stuffing box of the main driving shaft. Lubrication is effected under the control of the rotary valve of the compressor somewhat as in Specification 224,758. The side of the engine 1 is secured to the casting 2 so that the crank shaft 12 is lined up with the driving shaft 13 and that a space 3 is left for the gears driving the valve 4. The oil supply pipe 7 branches and leads to a duct 6 opposite the gas inlet for lubrication of the piston and also leads to a duct 8 whereby oil passes through the passage 9 to the gears and thence by a passage 11 to the crankcase.

Patent GB-327296-A (GB)
Title: Improvements in sewing machines
IPC: D05B27/02
Filed: 1929-04-13
Abstract: 327,296. Armstrong, J. J. V., (Union Special Machine Co.). April 13, 1929. Loop stitching.-A machine for stitching edges has a main shaft arranged above the plane of the work support and extending rearwardly of the stitching point in the general direction of the teed, and carrying eccentrics which directly operate the feeding and stitch-forming mechanisms to permit rapid and smooth working. The invention is illustrated as applied to an overedge stitching-machine with a needle 28 and two thread-carrying loopers 43, 46. The needle-bar 29 reciprocates in a sleeve 30 fixed to the lug 31 and has a collar 34 with a pin sliding in a slot and engaged by a link 36 connected to a crank 41 on the disc 42 on the actuating shaft 6. The looper 43 is mounted on a carrier 44 on a shaft 45. The looper 46 is mounted on a carrier 47 clamped to the shaft 48. The loopers are connected by an arm 50 and link 51 so that as the shaft 48 is oscillated, the loopers oscillate so that the needle loop is entered by the loopers. Feed by dogs.-The material is fed across the work support by a main feed-dog 8 and an auxiliary feed-dog 9. The dog 8 is adjustably carried by the bar 10 pivoted at 11 to the feed rocker 12 mounted on a shaft 13. The rocker is rocked by a link 15, adjustable stud 17, link 18 and mainshaft eccentric 19. The ball stud 17 is directly under the main-shaft 6 which is located in a vertical plane cutting a plane containing the line of feed at a small acute angle at the stitching point. The dog 9 is adjustably carried by the lever 20 pivoted on a member 21 carried by the main feed bar 10. The lever 20 has a rod 22 sliding in the sleeve 23 pivoted on an arm 24 adjustably fixed to a lug 25 on the frame. The arm may be held in adjusted position by lock nuts 26. Both feed bars are raised and lowered by the link 27, link 72 and eccentric 73. The sliding of the rod 22 changes the angular position of the auxiliary bar causing the dog 9 to leave the work slightly earlier than the main dog 8 so that the dog 8 has a slightly longer feed stroke to prevent stretching. Trimming or cutting.-The fabric is trimmed prior to stitching by a leger blade 59, adjusted by a screw 63, and a moving blade 60 carried by a head 67 on a rod 68 on a lever 65 fulcrummed on a support 66. The lever 65 is oscillated by the link 72 and eccentric 73, the link being connected to the lever by the ball joint 74. The cutting movements are thus synchronized with the up-and-down movements of the feed-dogs. Presser-bars.-The presser-foot 77 is carried on an arm 78 mounted on the shaft 79 which has an extension 80 over the end 83 of a lift lever 81 pivoted at 82 and operated manually.

Abstract: 891,764. Lamp holders. CHAUME, J. April 14, 1958 [April 19, 1957; March 6, 1958], No. 11758/58. Class 38 (1) A lamp holder 1 (Fig. 2) made of resilient plastic material, has mounting means, which may consist of a slot 5 adapted to receive a mounting bar, and contacts formed by lugs 4 and 7, the lug 4 having an arm 4a which contacts the lamp cap body and lies in a groove 3 while the lug 7 has a contact 9 co-operating with the centre contact of the lamp cap. The lamp may be secured in the holder by a bayonet connection or may have a screw thread on the cap which co-operates with a screw thread 2, or with fragments of a screw thread, or with pips 18 (Fig. 8), in the bore of the holder. In either case pressure of the lamp cap tip on the bottom of the holder, when in its fully inserted position, deforms the holder so that it grips the lamp and secures it against loosening by vibration. The holder may be mounted by providing it with a T-section projection or studs co-operating with suitable apertures in a carrying plate. Alternatively, it may be mounted in a carrying plate, the edge of the plate surrounding the holder fitting between lips of a peripheral flange integral with (20 in Fig. 15) or screwed on to (25 in Fig. 19) the body of the holder. In another modification the edge of the plate may be deformed to co-operate with a screw thread on the outside of the holder. Rotation of the holder in the carrying plate may be prevented by a projection on the flange fitting into a notch in the plate.

The tools 12, radially adjustable by screws 12b and clamped by screws 12a, Fig. 5, are carried by a head 11, Fig. 2, attached to a hollow shaft 10 driven from an electric motor by a belt pulley 25 and are moved axially periodically to engage the work 24 by a camsleeve 32 rotated at a slower speed than the shaft 10 by gearing 27, 31 connected to the shaft, the cams 37, 38 on the sleeve engaging a roller 39 mounted on a spindle 41 attached to the machine casing 42. The work plate 15 is attached to a shaft 16 carried by bearings 17, 18 and having secured thereto an arm 36 carrying a roller 35 engaging a cam 34 on the sleeve 32 to oscillate the plate, against the torsion of a spring 19, from the work-receiving to the work-holding and discharge positions. The blank is received in a notch 22, Fig. 1, of a removable block 21 attached to the plate and is transferred past a spring-pressed plate 43 and an end guide 44 to the station A where it is gripped in the notch by a rounded member 45 on a toggle lever 46 pressed to engaging position in contact with a stop 59 by a spring 58. The member 45 is adjusted on the lever 46 by a wedge 47 and is clamped by a nut 48. During the machining operation the plate 15 is maintained stationary by a plunger 49 engaging an aperture 50 therein when moved axially by a lever 51 actuated by a cam 54 on the gear 31 acting against a spring and the feeding position of the plate is determined by an adjustable stop 20. On leaving the notch 22, after machining, the work falls on a channel 60 which is pivoted at 62 and is oscillated by a link 66, shaft 68, arm 69 and cam groove 70 in the gear 31 to deliver the work to an outlet 61. An arm 72 is mounted on an extension 71 of the shaft 16 and has a notch 73 for engaging and steadying the rear end of the work, and guide 44 and carriage 75 for the shoot 23 are adjustable axially to suit the length of the work. A spring. 76 allows the shoot carriage to yield if a blank becomes jammed against the plate 15. Lubricating cutting-tools.-A tube 13a within the hollow tool-shaft 10 supplies slurry to the cutting tools 12. Stop-motions.-The lever 79, Fig. 1, of a switch box 77 rests on the blanks 24 in the shoot 23 so that when the shoot is nearly empty the lever will fall to release a switch finger 78 and stop the driving motor for the machine.
