Abstract: 108,532. Berry, A. F. Aug. 11, 1916. Bolts and studs.-Means are provided whereby the coils in an electric transformer can be set up and firmly held in place but cannot be subjected to such undue pressure as would be liable to injure the insulation. The screws or equivalent setting-up means, or the screws &c. and the means for setting them up, are so constructed as to admit only of the transmission of sufficient power to set up the coils. As shown in Fig. 2 the screw is formed with a fixed head b and a loose head c pressed together by a spring d and having their engaging faces formed with interfitting radial corrugations. The spanner for setting up the screw is applied to the loose head. In a modification the sorrugations are replaced by a series of balls seated in cup-shaped recesses. In the form shown in Fig. 7, a member c is interposed between the fixed head band the loose part m. A series of balls are seated in recesses in opposed faces of the parts m and c and the part c is mounted on a square part of the screw and is held up by a spring d, while the part m is held in place by an enlargement on the end of the screw. Fig. 9 shows a modification of this last form arranged as a separate device for engaging the square end of a screw. The part m is formed with a hexagonal head, or, as shown, with a handle o, and its lower end is closed by a ring n screwed in.

Abstract: 819,094. Spring - balanced windows. UNIQUE BALANCE CO. April 8, 1957 [May 1, 1956], No. 11416/57. Class 20(3) Mechanism for adjusting the tension of the inner helical spring 22 of a conventional two-spring spiral sash balance, also having an outer axially-extensible helical spring 11, comprises a foot plate 36 which is secured by a rivet 37 to a short plate 40 and carries, at its upper end, a tapered sleeve 52 which frictionally engages within the lower end of the outer spring 11, the plate 40 carrying a pawl plate 41 with a central aperture 55 and pawl teeth 58. A stop 42 on the lower end of the plate 40 projects through a slot 45 in the plate 36. A ratchet plate 56, having notches 57 to engage the teeth 58 and opposed inwardly-extending teeth 60, is urged downwardly on to the pawl plate 41 by a helical spring 22 contained between the lower face of the sleeve 52 and the ratchet plate 56. An adjusting member 46 has a lower flange 47, a collar 48 and a tubular extension 51 which fits within and projects beyond, the tapered sleeve 52 frictionally to engage within the lower end of the torsion spring 22. A transverse slot 50, extending through the flange 47 and collar 48 and into the lower end of the tubular extension 51 engages the inwardly directed teeth 60 on the ratchet plate 56. To insert the adjusting member 46 the slot 50 is first aligned with the rivet 37, then it is turned through an angle of 90 degrees so that the teeth 58 engage the notches 57. The spring 22 is wound up by inserting the end, e.g. of a screwdriver, in the slot 50 and rotating the adjusting member in an anti-clockwise direction, the plate 56 riding over the teeth 56 and re-engaging as rotation of the adjusting member is stopped. To allow the spring 22 to unwind a screwdriver, with a narrow shank, is inserted into the adjusting member 46 to raise the pawl plate 56 and disengage the teeth 58 from the notches. The spring 22 will unwind until the screwdriver is withdrawn, the spring 61 then urging the teeth 58 to re-engage with the notches 57. The adjusting mechanism is suitable for use with balances having only a torsion spring. As shown, a conventional two-spring spiral sash balance comprises the outer spring 11 and the inner torsion spring 22 which carries at its upper end a slotted nut 26 which follows the spiral of a rod 15 suspended from an eyelet 17 passing through a hanger 10 for the upper end of the spring 11, and receiving, e.g. a nail 20, which secures an outer tubular housing 12 to a jamb 21 of a fixed frame for a window.

Abstract: 1350987 Bumpers HOUDAILLE INDUSTRIES Inc 29 April 1971 [30 April 1970] 11665/71 Heading B7J [Also in Division F2] An energy storing/absorbing bumper system comprises bumper means 20 and a plurality of resilient spring steel buckling bars 22 each connected at one end to the bumper means 20 and for attaching (or indirectly connecting) at the other end to side members 21 of a vehicle frame end, arranged with the bars substantially straight between end portions thereof so that the bars 22 buckle resiliently when compressive forces are applied to their ends by an impact upon the bumper means 20, there being no force transmission crosswise to the bars, the bars resisting deflection substantially constantly and tending to return the bumper means toward its original position upon release of the impact force. The bars 22 may be pivotally, as in Fig. 1, or non-pivotally attached at their ends and may converge from the bumper means toward the vehicle frame members 21. A pair of the bars 37, Fig. 5, may be formed integrally by a single member which is attached to vehicle frame member 35 by bolts 40 and a resilient washer 41 allowing limited pivotal movement. As shown in Fig. 8, a bumper 49 carrying elastomeric cushioning strips 83 is reinforced by a bar 51 to which resilient buckling bars 68 are attached by bolts 82 provided with elastomeric washers 79, 80. Hanger members 57 each including a spring portion 65 extend from the reinforcing bar 51 to vehicle frame members 60, and the buckling bars 68 are attached to the hanger members 57 by a tie rod 71, again via elastomeric washers 70, 74. As shown in Fig. 13, the bumper 110 is supported by hanger bars 112 which are clamped against respective sides of frame members 111 so that friction layers 121 and 122 between spring washers 120 and bars 112, and bars 112 and members 111 respectively, damp movement of the bumper 110 toward and away from the vehicle frame members. Resilient buckling bars 123 are provided against the frame member sides each retained between the end of a hanger bar 112 and a stop 124, and held at its ends by a retainer flange 128 and a flange 127 of a bumper-supporting strut 115, so that its intermediate part can buckle outwardly from frame member 111. In another form, Fig. 15 (not shown), frictional resistance is provided by the interaction of telescopic tubes (133, 134) extending between bumper and vehicle frame. Various arrangements of resilient buckling bars in conjunction with such telescopic frictional units are described, Figs. 16-19 (not shown). Laminar resilient buckling bars 318 and 319, Fig. 24, may be used, bar 318 being supported against vertical displacement by flanges 361, (362) above and below it. The flanges 361, (362) are provided on a flange 351 of a bracket which is bolted to a vehicle frame portion 323, and a surface of flange 351 frictionally engages a surface of another flange 350 which is part of an L-shaped bracket bolted at 345 to reinforcing member 320 of bumper 315.
