Abstract: 929,032. Roller-bearing cages. ROBERT KLING WETZLAR G.m.b.H. Aug. 25, 1961, No. 30679/61. Class 12 (1). A roller-bearing comprises a cage to maintain rollers of the bearing at predetermined spacings made up of a series of like cage members (Fig. 1), forming one margin of the cage and a further series of members 1 forming another margin thereof, each member 1 having a recess 2 seating an end portion of a bearing roller 16 (Fig. 7), extending between the series, the members of one series being held in a predetermined position relative to those of the other by connecting pins 17a, 17b and 17c therebetween, successive members 1 of a series being connected together (Fig. 8) by engaging the pins 17a, 17b and 17c in the recesses 6, 7 of the end lugs 4, 5 arranged so that the recesses 6, 7 are then aligned when the members are end-toend. The lug 4 is at one side and the lug 5 at the other side of a longitudinal plane 8 through the cage member 1, the lug 4 contacting the lug 5 of another member 1 of a series in a coincident plane. The recesses 6, 7 are shaped so that the pins 17a, 17b or 17c can be snapped into them past cheeks of the lugs 4, 5. A modified cage member 9 is shown in Fig. 2. The rollers 18 (Fig. 8), are square in axial cross-section with recesses of a depth such that members 1 of one series abut on members 1 of the other. Each member 1 has a groove 3 formed and positioned as shown (Fig. 1) and in such grooves connecting members, e.g. 20 (Fig. 4b), engage in forming a composite bearing of two similar roller bearings. Connecting members such as 25 have portions which are angularly arranged relative to each other (Fig. 6b) and may be bendable synthetic plastic material with a core of bendable metal. In forming a composite bearing one or more longitudinal portions of a roller bearing may be omitted.

Title: Truck having extensible reach mechanism
IPC: B66F9/065
Filed: 1974-07-11
Abstract: 1481101 Luffing arm apparatus CLARK EQUIPMENT CO 1 July 1974 [11 July 1973] 30759/74 Heading B8H An extensible reach mechanism, Fig. 5, is mounted on a truck (10), Fig. 1 (not shown), the said mechanism comprising a pair of parallel posts 30 (only one shown) which are pivotally mounted at their lower ends at the rear of the truck, one end of a telescopic boom 44 being pivotally connected at 48 to each post 30 and a fork lift attachment is connected to the forward end of the boom 44 which is elevatable by means of a hydraulic ram 100 and which has an internally-mounted ram 124, the arrangement being such that when the boom 44 is initially raised by the ram 100 its forward end is retracted until that end reaches a position substantially level with the pivot points 48, and then the forward end of the boom 44 is extended in continued rising of the boom, so that the boom's forward end and the fork lift attachment connected thereto are caused to follow a substantially vertical path. Initially when it is desired to raise the boom 44 from its lower position the posts 30 are moved clockwise by means of a hydraulic ram 90 and thereby actuate a switch 160 which causes shifting of a valve 142 so that hydraulic fluid flows from a reservoir 134 through valves 140, 142 to flow dividers 162, 164, the former permitting fluid flow to the ram 100 to elevate the boom 44, and simultaneously fluid flows through the flow divider 164 and a valve 170 to the ram 124 whose piston 174 is connected by a rod 126 to the outer telescopic section of the boom 44 to cause retraction of the boom. When the forward end of the boom reaches the position which is substantially level with the pivot points 48 a switch 180 is tripped to shift the valve 170, thereby reversing the flow of fluid to ram 124 so that the boom 44 is extended on continued elevation thereof, whereby the boom's forward end follows a substantially vertical path. On lowering the boom 44 by means of the ram 100 it is initially retracted and then extended so that its forward end again follows a substantially vertical path.

Title: Improvements in and relating to friction clutches
IPC: F16D13/08
Filed: 1931-11-06
Abstract: 390,237. Friction and claw clutches. THOMSON, B., Combe Close, Woldingham, Surrey. Nov. 6, 1931, No. 30760. [Class 80 (ii).] In positive clutches of the type adapted. to be synchronized prior to coupling by engagement of a friction clutch while transmission of power to the driving-shaft is interrupted, the friction clutch is of the coil type. As applied to clutches for variable-speed gearing as described in Specification 332,302, [Class 80 (ii), Gearing, Variable-speed &c.], or with reference to Figs. 11 and 12 of Specification 339,694, [Class 80 (ii), Gearing, Variable-speed &c.], the driving clutch member 1 is slidable on the splined shaft 2 to bring internal teeth 4 into engagement with teeth 35 on a loose gear wheel 34, and has external cylindrical and conical surfaces 6, 5 to coact with the friction member 9 carried by the apertured intermediate or baulking member 7, which is normally held by a spring 25 against a stop collar 26. The member 9 may be cylindrical or conical helix or, as shown in Fig. 2, is formed by saw-cuts as a stepped coil with solid end rings 21, 24, the ring 21 being coned at 21a to coact with the surface 5 and the ring 24 pinned at 10 to the member 7, so that initial grip is obtained between the surfaces 5, 21a on axial movement of the member 1, and causes contraction of the intermediate coils 22, 23 on the surface 6. The coil may, however, act by expansion. If supplementary grip is required also for decelerating the wheel 34 into synchronism, the members 1, 9 may be coned at both ends and the coil so connected to the flange 8 of the member 7 by radial lugs with lost motion that it is tightened by torque in either direction. The two baulking-teeth 33, coacting with the apertures 30 in the part 7 by bevelled faces 31, 32, Fig. 5, are preferably distinct from the driving teeth 35, which may be formed on their periphery, as shown. In order to avoid difficulty in meshing the teeth 4, 35 if the friction clutch should " stick," the parts 33a of the teeth 33 ate cut away to allow some rotational freedom after passage of the member 7 thereover. This " reverse flanking " of the teeth 33 is equally applicable when they are spatially separated from the teeth 35 and when they act also as driving teeth.

Abstract: 536,824. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.V. and Berkel, W.A. Van,). Nov. 25, 1939, No. 30780. [Class 28 (ii)] The substance carrier comprises at least two substance-supporting surfaces, one of which is adjustable to give an oblique feed. The surfaces provide a support for the substance close to the cutting plane for each direction of feed. The invention is described in connection with revolving disc-knife machines. Three examples are given. (1) (Fig. 1) :-The carrier supports a plate having a raised surface 14A connected with a lower surface 14B by a ramp 14C. An auxiliary plate 17 hinged at 18 may rest on the surface 14B as shown to give an oblique feed, its surface being flush with 14B and a pin 23 thereon engaging a hole 22B in 14B, or it may be pivoted up over the ramp, the pin sliding along 14A and dropping into a hole 22A in 14A to give a perpendicular feed. The " last slice holder" 19, 20, 21 is secured to the plate 17. (2) (Fig. 6) :- Here the hinge 18 is approximately central and the curved edge of the (flush) plate 17 slides in contact with a curved step 14D. A side wall 30, slidably mounted on the plate 17, is spring-pressed towards the knife, a roller 37A mounted on the wall following a cam slot 38 so that initially the leading edge of the wall is maintained at a constant distance from the knife. A hand-screw (not shown) frictionally secures the plate 17 in any setting. (3) (Fig. 7) :- A wall 41 perpendicular to a wall 40 pivots on a pin 42. The strap 44 permits movement of the wall to and from the cutting disc 10. The wall is secured in place by a cam-slot 46 and nut 45. According to the Provisional Specification the hinge 18 in Fig. 1 may be situated at a part of the carrier remote from the knife.

Title: Improvements in music typewriters
IPC: B41J3/34
Filed: 1920-11-02
Abstract: 178,874. Fortoni, L. Nov. 2, 1920. Type-lever machines for writing music; case-shift mechanism; types. -Type-levers for printing music are provided with a type-member consisting of a disc which is formed with peripheral type-bearing flats of equal length and is revoluble for character-selection. Preferably, the type-levers b are each provided on the pivot a' with a loose pulley d<1> which is connected by an endless chain c to a pulley d on a triangular or hexagonal type-member a. The triangular members are employed for notes having long stems. A spring a<x> is inserted in the chain. A pinion d<2> on the pulley d' engages a rack e provided with an extension e<1> carrying an adjustable stop e<2> co-operating with a segment or plate f which can slide laterally on supports g, Fig. 6, and is adjusted by a hand-lever k. The keylevers A are connected by linkage n, o, p<1> to chains p which pass over pulleys px and are secured at q to the type-levers. When the handlever k is set in any, except the bottom one, of a series of notches l<x>, the plate f engages the stop e<2> of the operative type-lever before the type-lever reaches the platen B, the rack e being thereby arrested and, by means of the chain and pulleys, causing the type-member to rotate and select a type. When the hand-lever is set in the bottom notch, the plate f fails to arrest the stop e<2> and the type-member is not rotated, the type that is normally in position being selected. The first, third, and fifth notches are employed for selecting the faces of the triangular typemembers. The type-levers are connected to rods s<3> which pass through holes in the pivot-brackets a<2> and are engaged by returning-springs s<1>. Returning-springs s are connected to the key-levers. In the return movement of the type-levers, adjustable stops r on the racks are moved into contact with the pivot-brackets and thereby cause the type-member to turn to the normal position. Specifications 20490/10 and 2215/12 are referred to.

Abstract: 262,780. Lawrence Leather Co., A. C., (Assignees of Kelley, C. P., and White, E. W.). Dec. 8, 1925, [Convention date]. Multiple superposed coatings. - Enamelled patent leather is prepared by coating leather with a layer coloured, for example, by metal powder and subsequently adding a further translucent layer which may be of a different colour. In an example, the leather is first given a coat of linseed oil and pyroxylin which is then dried and a second coat of linseed oil and pyroxylin containing a metallic powder, e.g. aluminium or bronze powder, is then added. The second coat becomes incorporated with the first owing to partial solution of the dried coat. After drying, a fluid coat of linseed oil varnish containing naphtha, as used for black patent leather, is added, having, if desired, colouring matter sufficient to modify the colour of the second coat. The leather is then baked at about 140‹ C. and exposed to sunlight or other actinic light.

Abstract: 1359388 Brake discs for rail-vehicle wheels KNORR-BREMSE GmbH 3 July 1972 [3 July 1971] 31121/72 Heading F2E Two half-rings 10, 11, Fig. 1, constitute a brake ring 6 arranged on one lateral face of a wheel web 2, Fig. 3, each half-ring being retained by at least three bolts parallel to, and distributed around, the wheel axis, there being for each half-ring a number of guide parts which must fulfil the following requirements: (a) number not more than three; (b) number at least two less than the number of bolts retaining the half-ring; (c) engage in apertures in wheel-web and half-ring so as to inhibit relative radical displacement of them at the guide-part locations, and be parallel to the wheel axis; (d) be symmetrical relative to plane 23 containing the wheel axis and bisecting the halfring; (e) be no further from that plane than any of the bolts retaining the half-ring. Also, the bolts that are further from the plane 23 must engage between wheel web and half-ring with radical clearance. In Figs. 1, 3, each half-ring has four retaining bolts 12 to 15, the shanks of bolts 12, 15, extending with radial clearance (permitting thermal relative movement) through bores in web and half-ring (Fig. 2, not shown), while around each bolt 13 or 14 is located a guide part in the form of a cylindrical clamping sleeve 26 which has no radical clearance through bores 27, 28, 29. But in an alternative not accompanied by a drawing the guide parts for each half ring may be simply the shanks of certain retaining bolts having no radical clearance in the web and half ring bores; ribs 30 may be provided. Two further half rings form a further brake ring 7 on the opposite web. In Fig. 4, each half-ring has a single guide part in the form of a clamping sleeve 26<SP>1</SP> without a bolt, and four retaining bolts. Tilting of the half-ring about sleeve 26<SP>1</SP> is prevented by connecting the two half-rings together at 32. In vehicles for which braking operations to bring the vehicle to a halt, rather than retarding it, predominate, the cooling ribs 30 may be omitted and the half rings bear against the adjacent wheel faces so that the body of the wheel itself takes up and subsequently dissipates the heat.
