Abstract: 652,574. Reciprocating pumps. NATHAN MANUFACTURING CO. Oct. 19, 1948, No. 27133. Convention date. Oct. 22, 1947. [Class 102(i)] A multiple delivery lubricating pump comprises a housing 20 having a plurality of outlets, a rotatable cylinder block 29 having a cylinder 61 which communicates successively through a passage 70 with the outlets and which has an inlet port 69, and a plunger 60 reciprocable on its suction stroke by a pivoted cam member 54 which engages fixed members 49 disposed around the periphery of the block, and on its delivery stroke by springs 64 whereby the latter stroke is faster than the suction stroke. The plunger is connected by a pin 59 with a parallel piston 58 on which the cam and springs act. The cam is operable for either direction of rotation of the block which is driven by a shaft 34 through worm gearing 37, 28. The housing forms a lubricant reservoir and is provided with a filler cap and filter. Each outlet, 38, Fig. 4, has a delivery valve comprising a bushing 41 sealed within a recess 39 by a packing ring 43 and pressed by a spring 46 into engagement with the rotary block. A cylindrical valve 47, preferably of oil resisting rubber, is pressed by a spring 48 on its seat on the bushing.

Title: Improvements relating to tufter mechanism for brush making machines
IPC: A46D3/04
Filed: 1921-12-06
Abstract: 193,355. Fisher, C. E. Dec. 6, 1921. Brush-making machines. - In a brush-making machine the bristles are withdrawn from the magazine by means of a reciprocating tufter-bar having a notch with relatively fixed and oppositelyinclined jaws adapted to gather wisps as the bar reciprocates past the magazine. As shown, the bristles are housed in a magazine D which is open at the bottom, the bristles being pressed bv a follower 7 towards a tufter-bar E capable of sliding in a groove in a shaft 3 secured to the frame of the machine. The tufter-bar is connected to a link 15 adjustably connected to a lever 11 which is provided with a roller 10 engaging a groove in a cam wheel 8 on a driving-shaft 9. This shaft actuates, through links and levers, stapling-devices for applying wisps and staples to holes 19<a> in a brushstock 19. The tufter-bar comprises two sections 24, 25 spaced apart by a bar 26 to form a notch e. One end of the bar 26 is secured by rivets 27 to the section 25, the other end being secured by screws 28 passing through enlarged openings in the section 24 and into holes in a bar situated on the opposite side of the tufter-bar. The width of the notch e may be varied on loosening the screws 28 by means of an adjusting screw 30 mounted in a bracket 31 carried by the section 24 and engaging a screw-threaded lug 26b carried bv the bar 26. When inelastic bristles are used the notch is of the shape shown in Fig. 2a, the ends of the sections of the tufter-bar diverging downwardly and the face 24<c> being concave while the face 25<c> is convex. For elastic bristles the ends are shaped to converge downwardly. The wisps are gathered in the notch during the inward movement of the tufter-bar and are depressed, as the bar returns, by means of a guide comprising a bar f and two side-bars of which one is shown at f<1>. The bar f is resiliently pressed against the tufter-bar and is shaped at one end to prevent stray fibres from being carried out of the magazine. The side-bars are bevelled at the ends adjacent the magazine, the opposite ends being bent laterally and terminating in downwardly-projecting parts f<4> which co-operate with recesses k<3> in a pair of lower guides k to position the wisps during application of the staples. When no stapling devices are employed the tufter-bar may be reciprocated by hand or power.

Title: Improvements in or relating to knitting machines and knitted fabrics
IPC: D04B39/00
Filed: 1934-10-02
Abstract: 445,276. Knitting. JONES, T. H., The Aspens, Breck Hill Road, Woodthorpe, Nottinghamshire. Oct. 2, 1934, No. 28167. [Class 74 (ii)] A knitted fabric is obtained by pushing the new loops through the existing or previously formed loops. The machine for so knitting may comprise a cylinder and dial with instruments 22, 26 mounted in tricks therein. The instruments hove deep V-shaped throats formed therein, and, to facilitate the insertion of an instrument into the loop held by the corresponding instrument in the other bed, the instruments mav be bowed or cranked as shown in Fig. 2. In the formation of a plain fabric, the old loop OL is held in the throat of one instrument, e.g. a cylinder instrument 22, which instrument is in the projected or raised position. The new thread is fed to the throat of the dial instrument 26 which is in retracted position, and the instrument 22 is projected so as to push the new thread 7 in loop form into the loop held by the cylinder instrument. The cylinder instruments 22 are thereupon lowered, leaving the new loop NL held by the dial instrument as shown in Fig. 7. The dial instrument is slightly retracted and the cylinder instrument raised so that the web 22b thereof passes into the new loop, and finally the dial instrument is withdrawn, leaving the new loop on the cylinder instrument. For forming purl fabric, from the stage shown in Fig. 7, instead of the new loop being transferred to the cylinder instruments and the dial instruments retracted, the cylinder instruments rise to take thread from a feeder and force loops of that thread through the new loop, so that the succeeding loop in each wale is drawn in opposite direction. Rib fabric also may be produced. For forming antiladdering fabric as described in Specification 329,098, [Class 74 (ii)], the method for making plain fabric is followed to the stage when the cylinder instrument is raised to impale the new loop held by the dial instrument, and the dial instrument is withdrawn so that the old loop OL moves off the top of the instrument on to the lower web 26<a>. The dial instrument is thereupon projected to push the old loop through the new loop. Fig. 11, and the cylinder instrument is lowered leaving the old loop on its lower web and new loop upon its top edge. Withdrawal of the dial instrument and raising of the cylinder instrument to impale the old loop completes the process. Warp-knitted and Milanese fabrics may also be made. Specification 424,150 also is referred to.
