Title: Improvements in or relating to machines for operating upon marginal portions of shoesoles
IPC: A43D8/34
Filed: 1932-10-10
Abstract: 408,581. Skiving boot and shoe soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., PRATT, J. W., and HARRIS, A. W. J., Union Works, Belgrave Road, Leicester. Oct. 10, 1932, No. 28140. [Class 31 (i).] Boot and shoe soles are skived to a given edge thickness at the fore and heel parts and to a lesser thickness at the waist in a machine in which the knife 73 can be adjusted bodily towards or from the work support 11, and can also be tilted about an axis perpendicular to and passing through the cutting edge, graduated means 54, 107 being provided for indicating the amount of the two adjustments. The feed roller 11 may be turned by a handle 13 and by a power pulley 15, as described in Specification 21898 /09, [Class 31 (i)]. The bodily movement of the knife is effected by mounting the knife carrier 49 in the upper part 19 which is pivoted at 17 and carries at the front end a depending rod 25, hand wheel 31, and spring 33 which keeps the front end down. An adjustable stop 35 limits the downward movement, and the upward movement for introducing the work is effected by a lever 39 and treadle rod 41. The adjustment for thickness is made by a nut 53 with graduations 54, and a screwed hollow stem 51 integral with a sliding block 45 in the upper part of which the knife carrier 49 is mounted. Rotation of the nut 53 thus adjusts the block 45 in its slideway, and a spring 63 urges the block 45 upwards. The knife is secured in a boss 67 on the carrier 49 by a short rod 75 having an enlarged part 77 which receives the shank 72 of the knife ; a nut 79 adjusts the rod 75 and knife laterally, and the knife is clamped by a washer 81 and nut 83. The tilting movement of the knife for feather-edging the waist is obtained by shaping the carrier 49 to a circular arc and guiding it in a curved guideway 47 integral with the block 45 by means of a link 87 and rod 91 to which a treadle chain 92 is attached. A spring 93 urges the carrier upwardly, and adjustment is made by a wheel 97 and threaded abutment 95. Stops 99, 105 limit the tilting movement. Graduations 107 on one side of the carrier 49 are visible through a small window. There are also fitted an adjustable edge gauge 111 and presser foot 115. The knife edge is upturned at the forward end to ensure severing of the waste. For operating on wide margins of a sole requiring wider support rearwardly, the lower feed roll 11 is made with the hub displaced axially and the roll 11 is reversible on its shaft.

Patent GB-280521-A (GB)
Title: Phenol resin and process of making the same
IPC: C08G14/06
Filed: 1927-10-27
Abstract: 280,521. Bakelite Corporation, (Assignees of Bender, H. L.). Nov. 11, 1926, [Convention date]. Condensation products of phenols with anhydroformaldehyde amines or with formaldehyde and cyclic amines.-Resinous products are obtained by condensing a phenol with anhydroformaldehyde aniline or a homologue thereof and expelling aniline or its homologue from the condensation product, preferably by distillation in vacuo. The condensation may be effected in the presence of a basic catalyst such as hexamethylenetetramine. According to the conditions, the products may be potentially reactive, i.e. convertible by heat into hard, infusible, and insoluble bodies, or they may be slowly reactive or non-reactive products convertible by addition of a methylene-containing hardening agent into potentially reactive products. In one example, phenol and anhydroformaldehyde aniline are heated together under reflux at 210‹ C. and the soft resinous product is mixed with a filling material such as wood flour. The mixture is heated under atmospheric pressure or less so as to expel water and part of the aniline without completely hardening the resin, and the product is then moulded, in the usual way. In another example, phenol and anhydroformaldehyde aniline are heated together, and the excess of phenol and aniline is distilled off in vacuo until the product solidifies. The non-reactive product is rendered reactive by addition of hexamethylenetetramine or another methylene-containing hardening agent, such as anhydroformaldehyde aniline; mixtures of hardening agents may also be used. The Specification as open to inspection under Sect. 91 (3) (a) describes the manufacture of resinous products by condensing a phenol with formaldehyde (or its equivalent) and aniline (or other cyclic amine). In an example, a mixture of phenol, formaldehyde, aniline, and hexamethylenetetramine is heated first under reflux and then so as to allow water and part of the aniline to escape; instead of hexamethylenetetraamine, other basic substances, such as sodium carbonate or calcium hydroxide, may be used. This subject-matter does not appear in the Specification as accepted.

Title: An improved apparatus for automatic regulation of braking power on vehicles
IPC: B60T8/18
Filed: 1920-10-13
Abstract: 152,353. Scheuer, A., and Scheuer, H. Oct. 7, 1918, [Convention date]. Fluid-pressure; force transmitting mechanism. -Relates to the automatic regulation of the braking pressure for a railway vehicle in accordance with the load. To minimize the disturbance of such regulation by the rocking of the vehicle the variation in the deflexion of the supporting springs is transmitted to the brake adjusting mechanism through a spring coacting with a hindrance. In one arrangement, Figs. 1 and 2, a link 2 connects the spring shackle 1 to a crank 3 on a shaft 4 mounted in the underframe and carrying an arm 7 to operate the rod 9 leading to the brake adjusting member, and actuation of the rod 9 by jolts or oscillations of the bearing spring is minimized by a spring 5, normally unstressed, connecting the crank 3 to the shaft 4, and by the inertia of a mass 8 on the shaft. In a modification, the spring 5 is normally stressed to press abutments against the upper and lower edges of the crank 3 and of an arm fixed on the shaft 4. In place of the mass 8 the hindrance may be constituted by a fluid brake acting on the arm 7. In another arrangement, Figs. 7 and 8, the deflexions of two bearing-springs are utilized to actuate the rod 9, the spring which is less deflected constituting the hindrance. The movements of each spring are transmitted through a link 2 and arms 15, 17, fixed on a transverse shaft 16, to rods 18 operating bars 19, 20 rocking on a transverse shaft 21. On this shaft are also rotatably mounted the arm 7 for operating the rod 9 and a driver arm 22, a second driver arm 23 being fixed on the shaft. The spring 5, normally stressed, connects the arm 22 to a collar 24 on the shaft. Each arm 22, 23 has a lateral extension, and these extensions overlap the adjacent bar 19 or 20 and the arm 7 at opposite sides as shown. The arrangement is such that the arm 7 is operated only by simultaneous deflexions of the two supporting-springs in the same direction. In a further modification, two, three, or four supporting springs disposed on opposite sides of the vehicle are similarly interconnected.
