Title: Improvements in Turning Lathes.
Inventor: CHARLES PHILIPPE ALTMANN
IPC: B23B3/00
Filed: 1916-03-20
Abstract: 102,714. Altmann, C. P. Dec. 11, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Lathes, specially designed for turning shells, have a special bed, tailstock, and arrangement of tool-slides. The headstock and tailstock extend to the floor and are connected by two separate castings i, k, Fig. 2, located by machined projections and recesses, leaving a large central space to pass cuttings. The headstock and tailstock are further connected above by a tie-rod. The front casting i carries a saddle with a rest having three tools acting simultaneously to turn the cylindrical body parallel. The saddle is traversed by a lead-screw driven through change-gearing d<2>. Fig. 1, chaindriven from the hollow spindle. The saddle is linked to a lever m coupled to a bar-cam p, which feeds the cruss-slides supported by beds on the rear casting k and serving to end-face the base and cut the shell to length. The lever m serves for quick hand return of the tool-slides. The tailstock is formed as a turret provided with a centre g and with an aperture to pass in the shell. Mandrels. - The shell is located endways by an extension t, Fig. 5, of a mandrel secured in the spindle by a cap s<1>. A hand-wheel at the rear end of the spindle on a rod x controls a wedge core v engaging toothed centring and driving dogs u.

Title: Improvements in stationery feed mechanism for typewriting and like machines
IPC: B41J11/30
Filed: 1937-02-12
Abstract: 477,119. Typewriters &c. UNITED AUTOGRAPHIC REGISTER CO. Feb. 12, 1937, No. 4236. Convention date, Feb. 13, 1936. [Class 100 (iv)] In a web-feeding arrangement for typewriters and like machines, a frame mounted at the rear of the platen-roller supports front and rear shafts carrying endless belts or chains provided on the outer surface with pins for engaging perforations in the webs, the front shaft being driven by the platen-roller at such a speed that the pins move at the same speed as the periphery of the platen-roller. In the arrangement shown in Figs. 2 and 3, a pair of endless chains 31 provided with pins 34 pass over sprockets 30 on shafts 28, 29 mounted in a housing. 21. The housing is secured to rods 17, 18 on brackets 16 supported by a rod 13 on a frame C secured to the platen-carriage B. A web-pack 15 is placed in a stationary container, or on a plate 14 supported by the rod 13, and the webs 10 are passed around the platen-roller B<1> and over a plate 20 secured to the housing. The pins pass through slots in the plate and engage perforations at the top of the forms composing the webs. The plate has an incline 27 for stripping the webs from the pins. The webs are held down by a pivoted bail 49 and are tensioned by means of a spring-strip 19 secured to a bracket 19a adjustably secured to the rod 18 by a screw 19b. The pins 34 consist of heads which are pressed over extensions 36 formed on links arranged between the side links 37 of the chains. The pins have flanges 39 which ride on the plate 20 and can pass through openings 40 in the incline 27. The shaft 28 is supported by an arm 41 secured to the rods 17, 18. A pinion 42 on the shaft is driven from a pinion 44 on the platen-roller by means of pinions 43, 45, 46 on the platen-carriage. On release of a catch, the housing can be tilted backwards to permit the operator to reach beneath the shaft 28 and direct the webs below a guide 65 and around the platen-roller. The housing is then returned, and the webs are engaged with the pins. In an alternative arrangement, the pins are secured to an endless metal-belt having perforations engaging pin-wheels on the shafts 28, 29. Specification 468,284 is referred to.

Abstract: 470,705. Seats ; leg -rests. WELLS, E. G. Feb. 15, 1936, No. 4665. [Class 52 (ii)] A leg rest which can be used as a stool comprises a seat or rest member 13, Fig. 1, movably mounted on side members 12 supported from base members 10 by diagonal members 14, 15 which are pivoted to the members 12, 10 so that the whole framework can be moved to tilt the seat member 13 which is then used as a leg rest; the pivots are so arranged that the leg rest can be collapsed to a flat state. The framework can be locked with the members 12 horizontal by means of hook members 17 which co-operate with a cross-bar 16 between the members 15 to hold the framework rigid. The hooks 17 may be secured to a flap 20 pivoted at the ends of the members 12 so that when the flap is turned up the hooks 17 are disengaged from the bar 16 and the flap 20 can form a foot rest. When the flap is turned down and the frame is locked with the rest portion 13 horizontal, this portion can then be slidden along the members 12 to cover the flap 20 and act as a seat. Alternatively, the member 13 can be divided and the hooks 17 secured to one part of this member. Undue tilting of the frame and member 13 is prevented by cross-bars 11. In a modification, Fig. 5, a seat or leg rest portion 13 is slidably supported on side members 12 which are pivotally connected through diagonal members 14, 15 to arcuate base members 25. The whole can then tilt on the members 25, the portion 13 acting as a leg rest. When the device is to be used as a stool the framework and seat portion 13 are turned to the position shown in Fig. 8 and portion 13 is moved on to the horizontal side members 12 to act as the seat of the stool thus formed. Specification 7202/10, [Class 52 (ii)], is referred to.
