Title: Improvements in or relating to covers or enclosing devices for electric switches, accessories, and other electric parts
IPC: H01H23/04
Filed: 1924-12-24
Abstract: 248,133. Crabtree, J. A. Dec. 24, 1924. Covers of insulating material for switches and other electric devices are attached to the main portion of the switch or device by an intermediate member which has a screw connection with the cover and a screw or other connection with some fixed member such as the bridge of a tumbler switch. The intermediate member may take the form of a disc f, Figs. 1 and 4, having a helical periphery, which engages a screw thread in the cover, and an internal screw thread for engaging the socket portion b of the bridge. In this construction the pivot pin d for the dolly c by engaging in notches f<5> prevents the disc from rotating, but in modifications such locking is dispensed with, the intermediate member being instead semi-permanently or permanently attached to the cover as by the friction between them or by a ratchet and pawl device. Other forms of intermediate member are described. Fig. 7 shows a non-metallic intermediate member g having a coarse thread for engaging the cover and a fine thread for engaging the socket of the bridge. Specification 142,225 is referred to.

Abstract: 854,119. Printers' blankets. EEKHOUT, F. J. Sept. 29, 1958 [May 27, 1958], No. 31094/58. Class 100(2) A method of processing a printers' offset rubber blanket comprises applying a preparation composed of a polyester, an isocyanate or polyisocyanate, a cellulose ester and an organic solvent for said substances to the surface of the blanket, and drying the treated blanket at an elevated temperature, so as to form a closed surface which absorbs little or no water and gives off substantially all the ink to the paper, the ink and rubber dissolving in each other as little as possible. The blanket is previously cleaned with ethylacetate and/or butylacetate. The composition to be applied may be 50 gms. "Difinal" M and 40 gms. "Difinal" G. K. (Registered Trade Marks) (hydroxy-terminated polyesters), 830 gms. ethylacetate and 630 gms. butylacetate (solvent), 35 gms. "Desmodin" R (Registered Trade Mark) (a diisocyanate), and 15 gms. of a 15 % solution of nitrocellulose in acetone, intimately mixed to form a homogeneous solution. The blanket may be stretched in a roller, cleaned, and run through a flat tray containing the solution, being then dried by a plurality of spaced-apart infra-red lamps 30-40 cms. from the roller. The treatment is repeated several times, and the blanket then left for forty-eight hours. The drying causes condensation of the polyester with the isocyanate or polyisocyanate, forming a polyurethene resin. The components of the solution should be mixed only shortly before treatment.

Title: Improvements in or relating to dovetailing machines
IPC: B27F1/12
Filed: 1935-11-14
Abstract: 457,714. Dovetailing - machines. DRAPAK, K., Rochlice, near Liberec, Czecho Slovakia. Nov. 14, 1935, No. 31521. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 15, 1936.] [Class 145 (i)] In a dovetailing-machine the movements of the cutter are controlled by a rod having a number of guide fingers which are mechanically guided in succession around the profile of a single-tooth template, whereby a number of successive dovetails are cut. The cutter 8 is mounted on the shaft of a motor 7 carried by a slide 6 vertically movable on a slide 5 horizontally movable in the machine frame. The slide 5 is reciprocated to feed the cutter into and out of the boards 12, 12<1> which are clamped together at right angles, by a connecting rod 19 and crank pin 18 on a toothed wheel 15 driven by a toothed wheel 14 ; the amplitude can be altered by adjustment of the length of the connecting rod or by adjustment of the crank-pin 18 in a slot 17 in the wheel 15. A rod 9 connected to the slide 6 has guide fingers 10 the clear space between which corresponds to the breadth of the template 11. The template 11 is exchangeable in order that dovetails of different sizes may be cut, and the space between the guide fingers 10 is also variable, either by adjusting the fingers along the rod or by substituting a rod with differently spaced fingers. While the slide 5 is moving to the left, one pin 10<1> moves along the flat top of the template 11 and then follows the periphery of the upper half of the rounded portion thereof, the rod 9 and slide 6 descending by gravity. The succeeding finger 10<11> is then received by a member 21, Fig. 4, pivoted at 20 to the machine frame and supported by a cam disc 22 mounted on the shaft of the wheel 15; the pin 10<11> is thus lowered on to the top of the template, the pin 10<1> following the lower half of the rounded portion of the template and then moving along the flat underside of the template as the slide 5 moves to the right. The cutter 8 on the slide 6 follows the movement of the pin 10<1> and subsequently that of the pin 10<11> and so on, so that a succession of dovetails are cut.

Filed: 1939-12-13
Abstract: 537,244. Centrifugally operated friction clutch. PRITCHARD, N. J. Dec. 13, 1939, No. 32137. Convention date, Jan. 7. [Class 80 (ii)] [Also in Group XXXI] A windscreen wiper is driven at a substantially constant rate by a pulley engaging the fan driving belt or other driven element of the car engine, the pulley being caused to slip at speeds above a pre-determined maximum by the action of centrifugal arms. As shown in Figs. 1 and 3, the pulley comprises a drum part 50 engaging the fan belt 71 and fixed to the spindle 51 driving the wiper and a disc part 65 pivoted at 70 to a fixed bracket 56 and having a sleeve 52 in which the spindle 51 can freely turn. A spring rod 57 secured to a collar 56<1> on the sleeve presses the drum into contact with the belt. A ring 82 mounted on the sleeve 52 has a stud 63 projecting through a slot 64 in the disc 65 and connected by a strut 66 to the bracket 56. One or more weighted arms 75 pivoted to the drum 50 carry brake shoes normally free from the ring 82. Above a certain speed, however, the weighted arms swing onwardly causing the brake shoes to engage the ring 82. The torque applied to the ring thus tends to turn it about the stud 63 causing the whole assemblage to turn about the pivot 70 away from the belt 71. The Specification as open to inspection under Sect. 91 comprises also the construction shown in Fig. 4 (Cancelled). In this form the pulley 7 is formed with an internal core 13 against which are pressed by a spring wire 18, arms 16 pivoted to a disc 14 fixed to a spindle 15 connected by a Bowden wire 19 to a suitable wiper-operating mechanism. Above a certain speed, the arms 16 swing outwardly and slip occurs between them and the cone 13. This speed may be adjusted by a screw 24 which varies the pressure of the arms on the core. The pulley is mounted on a pivoted arm 8 by which it may be moved into and out of contact with the fan driving belt. This subject-matter does not appear in the Specification as accepted.
