Title: Improvements in apparatus for holding and lifting by means of suckers
IPC: B66C1/02
Filed: 1919-10-17
Abstract: 156,919. Pilkington Bros., Ltd., and Waldron, F. B. Oct. 17, 1919. Suction holding-appliances, specially adapted for peeling sheets of glass from polishing tables, transporting them in a substantially vertical position and placing them finally either horizontally or vertically in storage racks, are fitted with a lifting-sling arranged nearer to one side of the appliance than the other, and means are provided to enable each sucker element to remain in contact with the sheet during the bending of the latter in the peeling or subsequent operations. A channel-bar 1 has arms 2 of unequal length bolted thereto and carrying sucker elements 3. The bar also carries sockets 9 at one side for attachment of the lifting sling 10. The suckers are connected by flexible pipes 5 to a pipe 6 leading to a common pipe 8 in connection with an exhausting-appliance. The end suckers can be put out of actionby valves 14 when dealing with small plates. In operation, the pull on the sling 10 raises the shorter arms 2 before the longer arms and by lifting one edge of the plate first, gradually peels it off the table. The sockets 9 are arranged as nearly as possible in the same plane as the operative faces of the suckers, so that the sheet will hang nearly vertically during transport. To permit the suckers to remain in contact during bending of the sheet, the arms 2 are connected somewhat loosely to the bar 1 so that they can move slightly in a vertical plane. Each sucker also is arranged with both side and top clearance between the supporting-bolt 11 and the arm 2. Alternatively, the suckers may be pivoted to the arms on pivots parallel to the bar.

IPC: G06G1/00
Filed: 1922-09-21
Abstract: 204,520. British Thomson - Houston Co., Ltd., (General Electric Co.). Sept. 21, 1922. Calculating - apparatus.-A device for calculating values in connection with gear wheels comprises two relatively movable members pivotally connected together, one of the members having data arranged thereon visible through slots in the second member, which is provided with index numerals and pointers adjacent to the slots. It is used for determining the pitch-line speed or the horse-power per inch of width of a gear wheel when the number of revolutions per minute and the pitch diameter, or the speed in feet per minute, diametral pitch, and number of teeth, respectively, are known. The data on the lower member 6 are arranged within a circle divided into segments each of which represents a different tooth-speed in feet, per minute. The data in each segment are arranged in three zones. In the outermost zone are given tooth-speed in feet per minute and number of teeth. In the middle zone are rows of figures representing horse-power per inch of width, and in the third zone are rows giving revolutions per minute and pitch-line speed. The upper member 5 is disc-shaped and is provided with a radial slot D and with circumferential slots A, A<1>, B connected together by a radial slot C. Near the slot D are numerals indicating diametral pitch and projecting ears 8, 9 which act as a pointer. To find the pitch-line speed of a gear wheel having, for example, a pitch diameter of 10 and a speed of 500 r.p.m., the slot A' is made to register with the numeral 500 in the 3rd zone of member 6, and the slot C then aligned with the numeral 10 visible in slot B, the speed being read off in the lower part of the slot C. To find the recommended horse-power for a gear wheel having 23 teeth, a pitch diameter of 5 inches, and a speed of 300 r.p.m., the pitch-line speed is first found to be 655, then the disc 5 is turned until the pointers 8, 9 point to 600 (the next lower number to 655) in the 1st zone of member 6 and the slot D registers with the numeral 23, the horse-power being read off through the slot opposite the numeral 5 (the next higher number to 4.6 the diametral pitch).

Abstract: 296,998. Soc. Bouillon FrÞres. Sept. 9, 1927, [Convention date]. Stoppers, retaining-devices for; stoppers with valves.-A safety nozzle for fire-extinguishers and other containers liable to be subjected to abnormal internal pressures comprises two hollow members 1, 2. The member 2 is formed with a nozzle 4 and with threads 3 for screwing into the opening of the container. The member 1 is slotted at its lower end to form resilient lugs 6. A rod 11 screwed into a knob 10 has a collar 14 designed to pass freely through the nozzle 4, a tapered shoulder 13<1> designed to engage below the similarly shaped ends 7 of the lugs 6, and pointed tip 12. A doublecup shaped member 15 loosely arranged between the nozzle 4 and knob 10 houses a spring 17 which normally compresses a washer 18 against the nozzle 4. In fitting the nozzle to a container, the members 1, 2 being already screwed in place, the rod 11 carrying the member 15 and knob 10 is merely pushed down until the shoulder 13<1> snaps under the lugs 6, holding the spring 17 in compression. Abnormal pressure within the container will lift the member 15 against the spring 17, allowing escape of gas or liquid past the washer 18. To open the nozzle 4, the knob 10 is pulled sufficiently to spring open the lugs 6 and release the rod 11, which comes away with the member 15 and knob 10. In passing through the nozzle, the rod 11 will break up and remove any crystalline or other deposit or obstruction. The movable elements may be attached to an extinguisher by a chain.
