Abstract: 468,295. Typewriters. LAMSON PARAGON SUPPLY CO., Ltd., and GARDWOOD, V. W. Jan. 21, 1936, No. 1931. [Class 100 (iv)] Carbon-sheet arrangements.-To facilitate tearing off the used parts of a carbon-set employed in a flatplaten typewriter, a support for the carbon-set is slidably adjustable on an under frame and has channel-sides provided with projectible stops for engaging a stop-member on the carbon-set. In the arrangement shown in Figs. 1 and 4, the framework 7 of a flatplaten typewriter carries, at the rear of the platen 8, a frame 14 in which is mounted a support 13 for webs 12, and a carbon-set 10 such as is described in Specification 387,579. The frame 14 is provided with hooks 16 and thumb-screws 18 for engaging cross-bars 7<a>, 17. The frame is provided also with a web-pack container, a curved web-guide 30, and an inclined plate 15 for guiding the webs and carbonset onto the platen. The support 13 is adjustable forwardly and rearwardly on the frame 14 and is retained in either of two positions, about three-quarters of an inch apart, by means of a sliding catch 32 adapted to engage either of two slots in a bracket on the frame. The support is formed with channel-sides 19 receiving a stopstrip 11 of cardboard or the like on the backing sheet of the carbon-set. The stop-strip cooperates at each end with stops 20A, 20B, 20C, 20D, companion pairs of stops on opposite sides of the support being secured to arms 22 on a shaft 23 connected by linkage 27, 25 to a fingerlever 26 provided with a catch 29. The crossbar 17 is provided with adjustable web-guides 42 which are formed with parts for holding the webs in engagement with the platen, and steps for permitting free movement of the carbons, these being narrower than the webs. Initially the support 13 is in the rear position, and the stop-strip 11 engages the stops 20A. When it is desired to tear off the used parts of the carbons, the support is moved into the forward position and is locked by means of the catch 32, and the finger-lever 26 is raised. Next, the tear-off bar 9 is raised and the platen is depressed by means of the usual pedals, and the webs and carbons are pulled forwards until the stop-strip engages the stops 20B. The tear-off bar is again depressed, the webs are carbons are torn off, and the tear-off bar is raised, the platen being left in raised position to grip the webs. The support is then moved rearwards and locked, the front edges of the carbons being thereby released from the tear-off bar. The stops 20C, 20D are employed when it is desired to tear off other parts of the carbons. The stops 20A .. 20D may be replaced by pins D adapted to be inserted in holes.

Abstract: 1437312 Chucks H ARNOLD 16 Jan 1974 [19 March 1973] 02044/74 Heading B3B [Also in Division F2] A rotary workpiece chuck arrangement comprises a non-rotatable member 46, e.g. fixed to a spindle 37 housing; a plurality of jaws 21 displaceable radially in a body 1 of the chuck relative to the axis of rotation of the chuck; a clamping ring 4 rotatable about said axis to effect said radial displacement of said jaws; a drive motor for rotating the clamping ring; a coupling member 8 selectively engageable with the clamping ring 4 and being mounted on said non-rotatable member in driving connection with the drive motor; and engaging means 43, 44 for holding the body 1 relative to the non- rotatable member 46 to prevent its rotation, the engaging means being operable to hold the body 1 when the coupling member 8 engages the clamping ring 4 for drive thereof and being released when the coupling member is disengaged. The chuck jaws 21 are moved radially by a spiral groove 23 on the clamping ring 4. The chuck body 1 is attached to a spindle 37 by means of a centring ring 2. The coupling member 8 drives the clamping ring 4 by means of friction cone faces 5, 25, or by gears or a pin and slot drive. The coupling member 8 is mounted on the non-rotatable member by means of a coarse screw thread drive 31, 32 so that rotation by hydraulic or pneumatic means 16 of a ring 7 advances the coupling member 8 into engagement with the clamping ring 4. As the ring 7 also advances axially it also advances locking pins 41 to engage between bolts 44 carried by the centring ring 2 to lock the rotary part of the chuck arrangement relative to the spindle housing. A slip coupling is provided in the clamping drive to prevent damage to workpiece, e.g. a glass tube 22 held internally. When the coupling member 8 is disengaged from the clamping ring 4 spring biased pins 13 frictionally engage the chuck body 1 to prevent relative slip between the body 1 and clamping ring 4 to prevent release of a workpiece. The pins 13 are released from their spring pressure when the coupling member 8 is engaged by the pivoting of levers 33, 34. Alternatively a brake shoe arrangement may be provided.

Title: Improvements in or relating to machinery or apparatus for stretching leather and the like
IPC: C14B9/00
Filed: 1948-01-23
Abstract: 636,991. Stretching leather. HARRISON, J. H., and WILSON & SON, Ltd., E. Jan. 23, 1948, No. 2088. [Class 76] Apparatus for stretching leather comprises two. grooved or channelled pressure plates which are both pivotally associated with shafts whereby they may be moved into and out of opposed and adjustable relationship, and a power-operated draw roll whereby leather to be stretched is drawn between the plates, and against pressure exerted thereby, transversely of the grooves or channels. As shown, the pressure plates 8, 9 carried on pivotal members 6, 7 keyed to horizontal shafts 2, 3 disposed in vertically adjustable bearings in frame members 1, 1a are disengaged through the action of links 47, 47a on lower pressure plate-carrying member. 7 by depressing weighted treadle 45 mounted on shaft 43. One end of a butt of leather X, Fig. 5, is then passed between the open pressure plates 8, 9 and secured to draw roll 31, which tapers from each end, adjacent to the step 31e by canvas apron 56 laid over it. The draw roll 31 is freely rotatable on its shaft 28 until the clutches 32, 32a are engaged with clutch plates 31a, 31b on each end of the draw roll 31 by hand operation of the draw bar 57 acting through a pivoted lever mechanism. Treadle 45 is then released allowing members 6, 7 to pivot under the action of weights 46, 46a into a vertical position so that the leather is gripped between pressure plates 8, 9, while the consequent rotation of enmeshing toothed quadrants 10, 11 mounted on shafts 2, 3 by thrusting on a ratchet rod (not shown) in engagement with sprocket 35 rotates shaft 28 and, consequently, draw roll 31, sufficiently to take up any slack leather. Release of treadle 45 also acts on clutch levers 50, 51 through link members connected to treadle shaft 43, to engage clutch 21a on main driving shaft 19 thus causing rotation of worm-wheel 26 by worm 20. Worm-wheel 26 drives draw roll shaft 28 by spring-loaded pawls (not shown) engaging ratchet-wheel 27; this pawl arrangement allows worm-wheel 26 to idle when shaft 28 is driven by sprocket 35, while a free-wheel allows sprocket 35 to idle when shaft 28 is driven by worm-wheel 26. The pressure on plates 8, 9 may be varied by hand wheels 14, 16 and the clutch 21a may also be hand operated. After the leather has been drawn clear of the pressure plates it is reversed and stretched from the other end.
