Filed: 1924-08-22
Abstract: 229,582. Welffens, E. J. Aug. 22, 1924. Chain gearing; tension and supporting arrangements.-Relates to swing gearing for slubbing, roving and like frames comprising an Oldham coupling and automatic lubricating arrangements as described in Specifications 130,549 and 204,731. The thrust arm 12 carrying the chain wheel 11, which is driven by the chain 23 from a fixed wheel 24 and coupled to the bobbin wheel 7 by the Oldham coupling 10, is mounted on the pin of a crank 13 carried in bearings 14 on the reciprocating bobbin-rail box 1. The crank 13 is provided with passages as shown in Fig. 3, so that lubricant from a pipe 18 will serve the bearing of the wheel 11 and the coupling 10, and, by means of a passage. 29, the teeth of the wheel 11 and the chain 23. A triple-feed lubricator 15 mounted on the bobbin-rail box supplies the pipe 18 and pipes 16, 17 connected to the bearings 5, 8 of the bobbin shafts. The thrust arm is provided with a stud 19 that slides in a slot in a bracket 20 provided with a spring 22 which engages the end of the arm and thereby tensions the chain. The crank-pin oscillates in an arc E, F. Fig. 5, so as to move in the path C, D between the limits H as the bobbin-rail reciprocates in the path A, B between the limits G.

Title: Improvements in or relating to devices for holding safety razor blades while stropping and honing the same
IPC: B24D15/10
Filed: 1920-07-09
Abstract: 148,248. Thomas, A. B. Jan. 17, 1918, [Convention date]. Razors, safety. A device for holding the blade during stropping or honing comprises a longitudinally slotted member having blade-holding parts 4 and a handle 4a, formed from two parts secured together by a tubular rivet 6 or by other means, or from a single slotted piece of metal, and having the blade-holding parts secured together by a loosely fitting rivet 7 serving also as a hinge for a cap 8. The blade-holding parts are arranged to spring apart on raising the cap, and to be forced together when this is closed down, this action being brought about by bevelling the holder at 4<c> and bevelling the cap at 8<a>. The cap has an operating lip Sb and a spring friction catch 8<c>, and the holes for the rivet 7 are in the form of downwardly and backwardly inclined slots,. whereby, on forcing down the cap, the spring 8<c>, coacting with an inclined shoulder 4<e> on the holder, draws the cap towards the handle and causes the rivet to move down the slots, thus securing a wedging action at both ends of the cap; on raising the cap the blade-holding parts are allowed to separate. To adapt the device for single-edged blades with backing pieces, a slot or channel 10 is formed in the holder.

In a machine tool such as a lathe, means is provided to effect the equalizing of the temperature of parts of the machine by the passing of coolant from one part of the machine to another. In the embodiment described a drive shaft 25 is supported in bearings in a drive housing 24 and is rotatable by way of gears 26, 27. A bush 30 extends from the housing and has therein thrust bearings 28, 29 which axially support the shaft 25. Surrounding the bush 30 and abutting the housing 24 is a further bush 32 which is recessed to provide an annular space 34 between the co-operating surfaces of the bushes. The inner bush 30 is made from a material having a high coefficient of thermal expansion, e.g. bronze, and the outer bush 32 is made of a material having a low coefficient of thermal expansion, e.g. Invar, whereby, when coolant from another part of the machine is passed around the annular space the inner bush 30 expands or contracts axially to a greater extent than the outer bush and hence moves the drive shaft 25 in an axial direction to an extent proportional to the movement of other machine parts.

Title: Improvements in or relating to moulding mixtures comprising synthetic resins
IPC: C08G8/28
Filed: 1930-07-05
Abstract: Potentially reactive resinous compositions are made (1) by heating a phenol with a fatty oil in the presence of a "promoter" (e.g. phosphoric acid); (2) by treating the products obtained as in (1) with a further quantity of phenol and a methylene-containing agent; (3) by heating a phenol, tung oil, restricted amounts of a methylene-containing agent and a catalyst, such as a sulphonic acid derivative.  Processes (2) and (3) yield mixed phenol-oil and phenol-methylene resins.  Moulding mixtures which are readily workable and remouldable are obtained by incorporating fillers preferably in gelatinizable form with the above products.  A retardant such as rosin, ester gum, glycerol-phthalic anhydride resins, cellulose acetate and shellac for the phenol-methylene resin may also be added as well as pigments.  Moulded articles are made by pressing a mouldable composition as obtained above into the form of separate halves of a shell, inserting a core of non-plastic material such as wood (e.g. furniture elements) between the shell halves and welding the whole together by heat and pressure.  The manufacture of toilet-seats and steering-wheels is mentioned.  Wire coils may also be covered.  Pressures below 600 pounds to the square inch at the customary temperatures and as low as 100 pounds may be used. Preferred fillers for the moulding mixtures are cellulose, cotton flock, a -cellulose, sulphite pulp and an alkali-treated cellulose. In an example, tung oil is refluxed with phenol in the presence of phosphoric acid for 5 hours and the product then heated with more phenol and hexamethylenetetramine or paraform until the mass is viscous; the product dissolves in solvents forming varnishes; a moulding composition is made by adding cotton flock to the varnish with or without a lubricant, e.g. lime and calcium stearate, carnauba, ceresin or candelilla wax; furfural may be added as a plasticizer.ALSO:Moulding mixtures which are readily workable and remouldable are obtained by incorporating with or without the use of a solvent a phenolfatty oil resin or a mixed phenol-fatty oil and phenol-methylene resin with a filler preferably in gelatinizable form, e.g. cellulose, cotton flock, a -cellulose, sulphite pulp and an alkali treated cellulose.  A retardant for the phenolmethylene resin may be added as well as pigments. Specified retardants are rosin, ester gum, glycerol-phthalic anhydride resins, cellulose acetate and shellac.

Abstract: 627,181. Rope railways; turntables. WEBB CO., J. B. July 30, 1947, No. 20602. Convention date, June 10, 1946. [Class 104 (ii)] An overhead trolley conveyer system is arranged to handle long and relatively narrow loads supported at each end by a separate trolley on a single track and, by means of turn tables spaced apart by a distance equal to that between the two trolleys and each provided with a single track section, enable the direction of movement of the trolleys to be changed to bring them on to a double track comprising two parallel single track members. The trolleys may be moved manually while supported by the single track, and when on the parallel tracks moved by power driven means comprising an endless chain with dogs engaging dogs on the trolleys, whereby they are carried to another pair of turntables which are operated to transfer them to a single " exit " track. As applied to a system for conveying loads into and through an oven the entering load is supported longitudinally by a pair of spaced trolleys on a single track 11, and pushed along manually until the trolleys are suspended by track portions on the underside of two turntables 12a, 12b, whereupon the latter are rotated through 90 degrees about a central axis to align their respective track portions with the sides 13a, 13b of a double track leading into the oven. Each side of the double track is located immediately below an endless driving chain which passes around sprockets 32, 33 mounted at opposite ends of the tracks 13a, 13b, the sprockets 32 being mounted at the ends of a shaft 34 geared to a driving- motor 35. The load is carried through the oven until its supporting trolleys are carried by the track portions of turntables 14a, 14b, whereupon the turntables are turned through 90 degrees to bring the trolleys into alignment with a single track 16. Rotation of the turntables is effected by flexible pulley lines around parts of their circumferences, assisted by guide pulleys and lines around an operating winch whereby each turntable of a pair is operated with the other. The trolleys have a swivelled connection to the load and run on wheels supported by oppositely directed channels between which a pair of pivoted dogs project upwardly to engage between them one of a series of dogs secured to the endless driving chain.
