Title: Change speed power transmission mechanism
IPC: F16H63/44
Filed: 1969-02-12
Abstract: 1,200,044. Change-speed gear. FORD MOTOR CO. Ltd. 12 Feb., 1969 [29 April, 1968], No. 7568/69. Heading F2D.  Six forward and two reverse ratios of a synchromesh-clutched countershaft gear, comprising a direct-reduced auxiliary gear 26 arranged in series behind a main three-speeds and reverse gear 14, are selected by a single ballmounted manual shift-lever 152 which moves in two identical but axially spaced four-position H-patterns, Fig. 7, according as to whether low-range (reduced) or high-range (direct) is selected in the auxiliary gear. For this purpose the three shift-rails 130, 128, 132, Fig. 3, which select respectively low and reverse; second and high, in the main gear; and low and high range in the auxiliary gear each have two axiallyspaced lugs 170, 172; 166, 168 and 174, 176 respectively and the depending operative end of the manual shift lever 152, Fig. 1, is forked into spaced fingers 162, 164, which straddle one or other pairs of the lugs 170, 166 or 172, 168 of the main-gear shift-rails 130, 128, according as to whether the same manual lever 152 has previously selected low or high range in the auxiliary gear. Fig. 3 shows the shift rails 130, 128 positioned for neutral in the main gear, and the sail 132 set for low-range in the auxiliary gear, which latter has no neutral setting, all the shift-lug pairs being in axial alignment and the depending finger 162 of the shift-lever 152 being free to move transversely in the notches between the lug-pairs 166, 168 &c. In the main gear three speeds (two reduced and direct) and one reverse can now be selected in the usual H-pattern, Fig. 7, left, with the shift-lever fork 162, 164 effectively straddling the shift-rail lugs 170, 166. To change range the shift lever 152 is moved through neutral; transversely to engage the lug 174 of the auxiliary gear shift-rail 132; and backwards to slide the rail 132 forwards (dotted position) to upshift the auxiliary gear to high range (direct-drive), whereupon the same H-pattern, for ratios four, five, six and second reverse, can be repeated axially spaced from the proceeding low-range pattern, with the forked end 162, 164 of the shift-lever operating on the rail-lugs 172, 168 and the fork finger 164 occupying the spaces between the lug-pairs.  The shift-rails have drift-pin interlocks 194, 200 and positioning spring-detents, two horizontal 184, 135 and one (Fig. 2, not shown) vertical.

Title: Improvements in viscometers
IPC: G01N11/14
Filed: 1951-04-03
Abstract: 682,922. Viscosimeters. SCHOU, H. April 3, 1951 [April 3, 1950], No. 7727/51. Class 106 (ii). A viscosimeter of the type in which the viscosity of a substance is determined as a reaction of the resistance of the substance to the rotation of a body therein, comprises a rotatable driving-shaft having a connection with the body which is sufficiently flexible to allow the centre of rotation of the body, on rotation in the substance, automatically to be displaced in a direction towards the longitudinal axis of the container for the substance. In Fig. 1, a flexible shaft 5 connects the rotatable body 1 with the rotor of an electric motor 6, the stator of which is pivotally mounted at 8 so as to turn against spring means 10 and thereby give a measure of the viscosity of the substance 2 in the container 3 when the body 1 is being rotated. In Fig. 2 the drive between the rotatable body 17 and an electric motor 34 is by wires incorporating two universal joints 28, 29. The reactional torque from the substance 18 during a test, turns the stator of the motor 34 against the action of springs 36, 37. A pointer 40, pivoted at 41, is coupled to the stator of the motor 34 by two leaf-springs 48, 47, Fig. 3, any excessive force on the springs being prevented by the arms 44. The deflection of the pointer 40 relatively to a scale 43 is a measure of the viscosity of the substance. The ubstance in the containers can be maintained at a constant temperature by the circulation of a liquid in a surrounding jacket. The revolvable body 17, Fig. 2, may be a hollow cylinder open at both ends. An exchangeable transmission gear may be included between the motors and the revolvable bodies.

[Also in Group XXXVI] In a terminal block consisting of individual terminal bodies assembled on a U-shaped supporting rail, each body is retained in position by C-shaped springs attached to the base thereof and which snap behind a bent-over section of the rail. Figs. 3 and 4 show one embodiment wherein a pair of C-shaped springs 4, 5 are located in a slot 3 in the base of a body 1 and each is retained by bending out of the plane of the spring the free end of a U-shaped spring portion attached to one end of the C-shaped spring, so that it engages behind a shoulder formed between the slot 3 and a recess 6 in the side of the body 1. More than one slot 3 may be provided in the base and more than two springs may be provided in each slot. Fig. 5 shows another method of retaining the springs in the body wherein the free end of each U-shaped portion is bent outwardly in the plane of the spring to engage shoulders formed by an elongated recess 16. In a further embodiment, Figs. 9 and 10, opposite sides of the base 28 of the terminal body 24 are slotted at 25, 26 to receive the arms of a U-shaped spring embracing said base, the ends of the arms being bent round to form the C-shaped springs 27a, 27b. The spring may be reversed in order that the force necessary to release the body from the rail may be less than that required to attach the body. Similarly, in the previous embodiments, the individual springs in each slot may either have their free ends oppositely facing, as shown, to equalize the resistance to attachment or detachment of the body, or said ends may face in the same direction, either towards or away from the body to increase or decrease the resistance to detachment.

Filed: 1922-03-21
Abstract: 185,089. Revere Rubber Co., (Assignees of Gibbons, W. A.). Aug. 24, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Balls.-Tennis and like balls are vulcanized in a mould under internal fluid pressure, which shapes the article, and after removal from the mould, expands it to a perdetermined size at a predetermined pressure. Definite quantities of a gas-producing substance or mixture, e.g. 0.7 gm. of sodium nitrite and 0.532 gm. of ammonium chloride, although an excess of the latter is generally employed, are placed in a tennis ball " centre " in a mould, and on heating, evolve nitrogen which expands the centre in the mould, and after completion of the cure and removal of the mould, expands the centre further, and maintains a pressure of approximately 22.4 lbs. per sq. in. above atmospheric. Smaller quantities produce lower pressures, which however should always be at least 10 lbs. above atmospheric pressure. The gas-producing ingredients may be introduced in solid form, or in solution, or mixed with agar-agar, or the like. This latter method has the advantage that a gummy, protective coating is formed within the ball. Other gas producing substances specified are (1) any ammonium salt, and any nitrite, (2) sodium peroxide and water, (3) barium peroxide and acid, (4) hydrogen peroxide, (5) any organic compound or mixture, which on heating evolves nitrogen,. (6) an alkali and an ammonium salt.

Abstract: 367,596. Delivering envelopes, paper bags, &c. from machines. WINKLER, A., 30, Seminarstrasse, and DœNNEBIER, M., 46, Engerser Landstrasse, both in Neuwied, Germany. March 18, 1931, No. 8367. Convention date, April 22, 1930. [Class 100 (i).] Envelopes, paper bags, or other flat articles of paper or similar material delivered from a machine to a stacking-device are engaged, during delivery, by a guide 13 which causes the trailing edge of each article to be bent away from the stack 20 when its leading edge is in stacking position so that when the guide is moved away the trailing edge springs into stacking position due to the tension produced by the bending. Rollers 1, 21 deliver the article from the machine and have oscillating pushermembers 40 pivoted thereon which are projected by cam-and-lever devices to engage the rear edge of the article as it leaves the rollers 1, 21 so as to effect the final movement of the article into the stack. The guide 13 has a curved edge 14 concentric with the roller 1 to bend the trailing edge of the article away from the stack and is formed with a hooked end 15 which engages the edge of the stack so as to allow the article to slide into position between the stack and a fixed plate 36. When the leading edge of the article has reached the stacker-table 22 the members 40 are retracted and the guide 13 moved upwardly by levers 17, 19 operated from a cam on the shaft 12 of the roller 1, so that the article springs into stacking position. The guide 13 is then lowered so that the hook 15 engages behind the last delivered article. Simultaneously with the lowering of the guide 13, pressure members 5 fixed to and adjustable circumferentially of the roller 1 engage the stack and push it back slightly for the succeeding article to enter. The articles are stacked on a slowly-moving endless belt, the supporting pulleys 24, 29 of which have shafts 23, 24 journalled in the ends of the table 22. In order that the top of the stack may be kept at the same height relatively to the delivery devices, the table 22 is pivoted at one end 23 and the other end is carried by arms 30 fixed to a shaft 32 adjustable by a hand-wheel 31. The number of articles delivered may be indicated by the displacement of one of the articles transversely of the stack at definite intervals.
