Title: Device for operating a syringe on its retraction stroke
IPC: A61B5/15
Filed: 1975-04-02
Abstract: 1495671 Loading syringes W SARSTEDT [trading as WALTER SARSTEDT KUNSTSTOFFSPRITZGUSSWERK] 2 April 1975 [2 April 1974] 13437/75 Heading A5R [Also in Division Fl] The retraction stroke of a piston and cylinder syringe 1, 2 is effected using a device to which the syringe is releasably mounted and which itself comprises a piston and cylinder 13, 14 which, when unlocked from their telescoped position, Fig. 1, by operation of pawl 20, move apart to their Fig. 3 position due to the lower pressure induced on the left hand side of the piston 13 during telescoping. An abutment 24 retracts the syringe cylinder 1 to draw in blood from a patient via a cannula (not shown) attached to mount 6. The device piston has its rod 12 screwed into a support casing such that the device cylinder 14 moves over the piston. The retraction stroke may be stopped slightly short by the engagement of pawl 20 in a second detent 17". In this way, release of the pawl from detent 17" allows completion of the stroke as determined by a stop 12' engaging cylinder plug 11 such that any small blood droplets remaining in the catheter are sucked in. In a modification Figs. 5-8 (not shown) the syringe is releasably mounted to the device by means other than co-operation of flange 5 and fingers 10. In either modification cylinder vent plug 15 may be replaced by a plug having a vent bore including a check valve, an axial air inlet bore in parallel with the vent bore, and a rotatable exterior disc having different diameter bores which can be selectively aligned with the axial bore whereby the rate of air ingress into the cylinder during its outward movement, and thereby the syringe retraction stroke speed, can be varied as desired.

Title: Improvements in or relating to machines for operating upon boot or shoe parts
IPC: A43D111/00
Filed: 1919-05-28
Abstract: 150,403. British United Shoe Machinery Co., (United Shoe Machinery Corporation). May 28, 1919. Breasting.-Relates to improvements in cutting apparatus for breasting heels before they are affixed to shoes, and especially to an adjustable magazine which is set by any one heel to a size so as to accommodate a pile which falls freely by gravity. The apparatus is specially applicable to the invention described in Specification 120,231. The heels are placed in a pile between adjustable sides 22, 23, Fig. 4, of a magazine and are confined therein by adjustable frames 80. The magazine is set by placing one heel between jaw guides 24, 25, Fig. 5, which by a, system of pivots and levers set the sides 22, 23 to allow the heels plenty of clearance to fall by gravity. The heels are fed one at a time by a slider 100, Fig. 1, pivoted on a table 7 to a flat or convex knife 12 reciprocating in a vertical slide. Cut heels are delivered by a shoot 180, Fig. 10, and chips are caught by shots 176 in a grooved slide and fall through into a chip shoot 172. The sides 22, 23, Figs. 4 and 5, are adjusted by rocking .shafts 26, 27 carried in a cutting block support 6, Fig. 1, pivoted at 9 to the main frame 4 of the machine. The rocking-shaft 26 is operated by a handle 60. Fig. 5, and has arms 42, 44 to which the sides 22, 23 are connected. The shaft 27 is connected to the shaft 26 by gearing 30 so that it moves in an opposite manner. The sides 22. 23 are guided by vertical rods 68, Fig. 4, suitably pivoted in a frame 20. A spring 33, Fig. 5, tends to press the sides 22, 23 together. The heels are placed upside down in the magazine with the concave part resting on the convex block 7, Fig. 4. The part to be breasted rests against a plate 88, which is yertically adjustable by a screw 98 to give the necessary clearance towards the cutting apparatus. A heel is passed beneath the plate 88 to a clamp consisting of a pivoted plate 105, the further ends 103, Fig. 1, of which are engaged on a rod 108. The rod 108 is frictionally held in a box 113 and is moved up and down between clip limits 111 by the movement of the cutting head. The downward movement clamps the plate 105 and holds the heel. The slide 100 having pushed the heel into place a cut is taken by the knife 12. The slider then moves forward again and a finishing cut is taken.. The slide then moves to position another heel which freely falls down from the magazine. The magazine is adjustable sideways by a screw 40, Fig. 5. so that each heel is central with the knife. The knife is held in clamps 114, Fig. 6, adjusted by screws, 120 carried by the frame 110, Fig. 1. The knife is adjusted vertically by a screw 139 and a movable gauge.130, Fig. 6. As the angle of the cutting-block is adjustable the curvature of the knife edge is ground accordingly and is made to fit a pivoted gauge 160, Fig. 8, which is set at the same angle as the block.
