Title: Improvements in & relating to means for combining weighing scales or balances with calculating or other auxiliary apparatus
IPC: G01G19/00
Filed: 1930-01-17
Abstract: 339,165. CuÚnoud, F. E. Feb. 6, 1929, [Convention date]. Computing-apparatus.-A device for combining a weighing scale with an auxiliary apparatus, such as a calculator of the kind wherein the monetary value of the commodity on the scale pan is ascertained after setting-up the price, comprises a member following the movements of the pointer or beam of the scale, a movable element moved by this member, means for liberating the member and the element from each other at the end of each weighing operation so as to render the pointer independent at this moment, and clamping-means for securing the movable element which is provided with a stop serving as an abutment for setting the weight factor in the auxiliary apparatus. An arm 1 attached to the knife-edge 2 of the scale pointer engages a fork 5 slidably mounted in a plate 6 pivoted on a knife-edge 7. The plate 6 carries a stop 6a which constitutes an abutment for the setting of the weight factor in the calculator. When the plate 6 has come to rest on the completion of a weighing operation, operative connections with the calculator clamp the plate and actuate a push member 11 so as to liberate the fork 5 from the arm 1, thus entirely disconnecting the weighing scale from the calculator. To prevent the control handle or mechanism of the calculator being operated before the weighing scale has come to rest, the dash-pot 12, Fig. 5, of the scale is provided with a flexible diaphragm 13 at the base connected by a lever 16 to a rockable lever 20. With the parts at rest a hole 24 in the lever coincides with a similar hole 25 in a fixed part 26, and permits a pin forming part of the calculator to pass through when the calculator is operated. If, however, the weighing scale is moving, the rockable lever 20 is displaced and the passage of the pin is prevented and the calculator cannot be operated.

Title: Improvements relating to cleaning devices for drafting arrangements of textile spinning and like machinery
IPC: D01H5/60
Filed: 1960-01-21
Abstract: 881,707. Clearing drafting rollers. RIETER & CIE A. G., JOH, JACOB. Jan. 21, 1960 [Jan. 23, 1959; June 22, 1959], No. 2248/60. Classes 120(2) and 120(3) A drafting arrangement for textile spinning and like machines comprises one or more top rollers, support means for the top roller or rollers, a clearer roller resting on at least one of the top rollers having a surface capable of accumulating fibres, and a comb having pointed teeth for picking fibres from the surface of the clearer roller. In the form shown in Figs. 1 and 2 a covered slightly conical clearer roller 4, rests on two upper drafting rollers 1 and 2 and is itself cleared by the teeth 14 of a comb 11. The angle between the comb and the tangential plane to the clearer roller at the intersection of the comb with the roller surface, is preferably between 80 degrees and 110 degrees. The comb is mounted in a slotted rod 9 which is clamped on a support 7 by resilient members 8 and has protuberances 15 fitting into recesses 16 of the clamps 8 to allow the rod 9 to rotate and not damage the needles should jamming occur. Due to its conicity the roller 4 tends to move to the left (in Fig. 1) and its axial movement is limited by a shaft 5 extending from the roller and abutting against a stationary member 6, thus leaving at the other side of the roller a clear passage for fly which is carried away by an air current as indicated by the arrows. Alternatively the axial movement of the clearer is limited by arranging a strap to pivot about the rod 9 and rest between two rings fixed to the shaft of the clearer roller. Rollers 1 and 2 rotate with different circumferential speeds and the circumferential speed of the roller 4 lies between these two speeds. In Fig. 4 the clearer roller 25 is in contact with only one upper drafting roller 1 and is braked to provide a wiping effect by having its shafts 27, 28 bear frictionally on stationary supports 26 which are mounted on the top roller supporting means. By mounting rings on the shafts 27, 28 their effective diameter may be increased so varying the braking moment on the clearer roller and its rate of slip on the drafting roller 1. In Fig. 4 the teeth of the comb lie in the same plane as the comb plate but are inclined at an angle # (preferably between 60 degrees and 90 degrees) to the axes of the roller 28 so that fly may easily be blown from the teeth. Specification 873,154 is referred to.

Title: Improvements relating to picnic cases, trunks, uniform cases and similar articles
IPC: A47B3/10
Filed: 1932-01-26
Abstract: 388,549. Picnic and other cases with hinged legs. SHAKESPEARE, H. T., Garrison Works, Garrison Lane, Birming- ham. Jan. 26, 1932, No. 2329. [Class 52 (iii).] Comprises a picnic case, trunk, or like article, having hinged legs each of which is supported by a spring-influenced collapsable strut, hinged to it and automatically brought into snapping engagement with a stop on the case when the leg is moved into extended position, while tending to close the leg when the snap engagement is released. A picnic or like case a has a hinged lid b which closes over a weather rib c and at each end of the case is a housing d for a pair of hinged legs g, h, as shown by Fig. 1, which is a sectional view through one housing and by Fig. 3, which is a part sectional view on the line 3-3 of Fig. 1. Each leg has a spacing boss j where the pivot pin k passes through and is provided with a lug m on which is pivoted a strut n. At the other end of each strut n is a notch o adapted to engage with a pin q. A torsion spring fitted at the lug m tends to project the strut n away from the leg. A leg is collapsed into the housing d by depressing its strut n to free the notch o from the pin q, so that the strut moves into a position about parallel with the folded leg. When the leg is drawn out, the strut n is swung out with it and slides in engagement with the pin q until the notch o snaps into engagement with the pin under the influence of the torsion spring. The two legs in each housing, when collapsed, lie side by side. For wide cases, a separate pin q may be used for each strut. A wire guard r on each strut prevents accidental disengagement. If desired, the strut may be provided with a slot working on the pins and having a " dwell" at the outer end for engagement therewith to retain the strut in position.

Title: Improvements in or relating to the manufacture of buckles, buttons or like articles covered by fabric or the like
IPC: B29D19/00
Filed: 1952-01-30
Abstract: 705,771. Buckles; buttons. MULLER, T. R. Jan. 30, 1952 [Feb. 17, 1951; May 30, 1951; Nov. 12, 1951], No. 2515/52. Class 43 In making a covered buckle or button by applying a "glued-on" fabric or other material to a frame or former made of paper-board, metal &c. at least part of the frame is coated with a quick-drying thermo-adhesive substance, the frame is covered mechanically with a fabric or other material which is cut to shape beforehand and finally caused to adhere to the frame or former by the application of heat and pressure. In an example a buckle frame or former 2, Fig. 2, is covered with a piece 1 of fabric or other material by means of a die 3 comprising two cores or upwardly projecting portions 4, 5 with detachable guide members 6, 7 mounted in cavities 8, 9 therein and serving to guide the material 1 by engaging within corresponding apertures therein, a plunger tool such as 14 being used to force the material down into the die. The material 1 is thus held between the frame 2 and an ejecting-plate 10 located at the bottom of the die and above four holes 13 provided in the base of the die. After the removal of the detachable guide members 6, 7 the die is inverted and placed upon an assembly device comprising a base plate 15, Fig. 4, provided with two pairs of upwardly projecting guide pins, such as 16, which register with the guide holes 8. 9 of the inverted die. After heating the assembly device to a temperature sufficient to soften the thermo-adhesive substance on the frame 2, the ejecting-plate 10 is forced downwardly by a device comprising a plate 11 with studs 12 arranged to project into the holes 13 in the base of the inverted die, so that plates 18, 19 supporting the die are forced downwardly against the action of compression springs 20, 21. The fabric 1, already turned down on the frame 2, as shown in Fig. 4, is thus pressed against heated projecting portions 24 of the base plate 15 and turned inwardly and secured on the frame 2. After inverting the die to its original position a backing piece 25, Fig. 5, corresponding in shape to the buckle. is coated with a thermoadhesive substance such as vinyl acetate and pressed upon the rear face of the buckle by a heated punch 26. The ejecting plate 10 is operated finally by the plate 11 to remove the covered buckle from the die 3. A method of making a reinforced buckle frame consisting of a metal frame embedded in paper board is described.
