Filed: 1940-03-11
Abstract: 539,369. Measuring stop-motions for looms. FROST, W. H. March 11, 1940, No. 4485. [Class 142 (i)] A stop-motion which includes measuring means of the notched disc or drum and finger type is fitted with an additional notched drum &c. 1 and finger 16, this drum measuring only a small number of picks per revolution. As shown, the first measuring means (at the right-hand of the Figures) is that described in Specification 409,666, and the ratchet lever d<SP>3</SP> which drives through worm gearing the notched disc which co-operates with the finger h<SP>3</SP> is connected to a lever 14 which drives the notched drum 1 directly through a ratchet 5 and pawl 12. The finger 16 is carried by the same lever h2 as the finger h3. A setting wheel 6 at one side of the drum 1 carries a spring pawl to engage the notch 4 from the inside of the drum 1. A disc 19 with a bevelled edge can be rotated on drum spindle by means of a cord 29 and returned to its normal position, shown in Fig. 2, by a spring 30. When the notches in the two measuring drums &c. allow both finger h3 and 16 to enter, the lever h<SP>2</SP> falls and stops the loom. A projection 17 on the lever h2 engages the tail 18 of the pawl 12 and disengages it from the ratchet wheel 5. The cord 29 is now pulled and a cam projection 23 or the disc and a corresponding slot 25 in a fixed collar first cause the disc to move axially against the action of a spring 21 ; the bevelled edge of the disc 19 through a lever 27 keeps the pawl 12 out of action and brings a pawl 20 on the disc 19 into engagement with a second ratchet 181 on the drum 1 so that the drum 1 is turned back to its starting position. When the cord 29 is released, the spring 30 returns all these parts to normal position as shown in Fig. 2.

Filed: 1941-04-22
Abstract: 549,674. Automatic control systems. PAULUS, C. L., and STOUT, R. K. April 22, 1941, Nos. 5179 and 5180. Convention dates, April 22, 1940, and Aug. 19, 1940. [Class 38 (iv)] [Also in Group XL] In a leader gear system for automatically controlling the steering mechanism of a moving body, the pick-up system on the body comprises a pair of tuned inductance coils disposed so that, when the body is correctly following the course, the axes of the coils intersect at a point located vertically above or below the cable at a distance therefrom which is a fraction of the distance between the cable and the coils. The invention may be applied to power driven vehicles including lawn-mowers, agricultural implements, and may be used for controlling aircraft on the ground or when landing and taking off. The system may be provided with lamp indicators for use when the body is manually steered, and with auxiliary arrangements for controlling speed, indicating mileage, stopping the power-unit and applying brakes. One form of the complete system is shown in Fig. 18, the relationship of the pick-up coils to the leader cable being shown in Fig. 23. The cable comprises a main coursedefining member 161a with off-set portions 161b-d for the auxiliary controls. Different control frequencies or different cables may also be used for the various controls. The course controlling pick-up coils 164, 165 are tuned to the leader cable frequency by condensers and have their axes inclined to meet a short distance above the cable a as shown in Fig. 23 so that when the body is on-course, the coils are equally excited, but when slightly off-course one coil has maximum excitation, both coils being ineffective when the body is off-course to a considerable extent. Coils 166-168 effect the auxiliary controls in conjunction with cable portions b-d. The outputs of the course-controlling coils 164, 165 after amplification, control a right-left indicator 170 and a pair of relays 178, 179 which control right and left lamps 188, 189 and differential circuits of a control solenoid 184 or differential relay which actuates the steering mechanism under hydraulic control, Fig. 12 (not shown), or by means of an electric motor, Fig. 24 (not shown), when neither relay 178, 179 is operated .(badly off-course), red lamp 190 is lit and magnet 192 releases a member 193 which short-circuits the sparking plugs. Speed control is effected by displaced cable portions 161b, 161d which generate impulses in coils 166, 167 to control increase and decrease of speed. The impulses, after amplificaton, operate relays 199, 200 which repeat them to magnets 202, 204 whereby ratchet wheels on a shaft controlling the throttle 174 are driven in opposite directions. A mileage indicator 217 is driven by impulses from coil 168 due to spaced effect portions 161d of the cable.

Abstract: 588,779. Jacks. PAGE, H. E. March 6, 1945, No. 5573. Convention date, March 6, 1944. [Class 78 (iii)] A hydraulic jack provided with a load lifting piston 30, Fig. 2, reciprocally mounted in a main cylinder 10 which is supplied by a pump 45 with pressure fluid for raising the piston, includes lever means 70 so mechanically associated with the work piston and the pump operating member as to mechanically move the piston quickly into engagement .with the load, whereupon the continued movement of the piston to lift the load takes place hydraulically by the pressure fluid forced into said main cylinder. The operating handle journalled into the boss 68 reciprocates arm 70 and spring 78 to press collar 75 against piston 30 in order to raise the latter. At the same time the operating handle depresses arm 69 and piston 45 to force oil through passageway 50 and valve 61 to chamber 47. Additional oil flows from reservoir R through passageway 82. When the piston pad 32 contacts the work the latter continues to be raised solely hydraulically. The piston is released by screwing member 85 to open valve 61 and to allow oil to flow back to reservoir R. Collar 75 is kept in position by an additional spring (not shown) which is attached to the base. Piston 30 has. threaded core 31 for extension purposes. In the modification, Fig. 5, the operating handle 106 fulcrummed in piston 103 at 107 actuates collar 120 through rod 115. Piston 100 is also actuated but valve 61 is of such strength that no oil passes from chamber 46 (flowing only from' reservoir R) until the pad 32 contacts the work when valve 61 will yield and the consequent elevation will be carried out hydraulically. The fulcrum point 107 rises and the front opening is covered by flexible rubber covering 110. Collar 120 may be formed of resilient leaves, and rod 115 with a lower portion fitted with a spring that will yield at a predetermined compressive pressure so that overloading is avoided.
