Title: Improvements in spools and processes wherein a wire or other filament is drawn off aspool
Inventor: BOLTON DONALD ALFRED
IPC: H01J19/00
Filed: 1965-06-04
Abstract: A spool mounted for rotation on a spindle is associated with means whereby rotation of the spool causes bearing balls to travel over and deform an elastic surface, the resulting constant amount of work done per revolution of the spool as wire or thread is withdrawn therefrom determining the tension in the wire.  By increasing the pressure of the balls on the elastic surface the tension in the withdrawn wire or thread increases.  In Fig. 1 (not shown) the elastic surface is in the form of an annular disc 10 and the balls 8 are pressed against one flat side face of the disc.  In Fig. 2 (not shown) the elastic surface is in the form of a pair of side-by-side rings 16, each of circular cross section, the balls 17 riding in the groove formed by the adjacent rings.

Abstract: 338,119. Bramwell, I. L., and Birtley Iron Co., Ltd. Aug. 6, 1929. Pneumatic separating.-In apparatus for separating granular materials, such as coal, according to size of the type in which the materials a are fed by way of a shoot c into a vertical flue f and are there acted on by a rising current of air which carries off the constituents below a predetermined size, the feed shoot is arranged so that the materials will rest quiescent at the natural angle of repose until disturbed by the entrance through the aperture d of a subsidiary air current induced by the fan l of the aspirator or provided by an additional source. In the arrangement described, the materials rest on plates m, m<1>, which are adjustable to vary the size of the aperture d. The main separating air current enters the bottom of the flue by openings i, h which may be covered with gauze, perforated sheet metal &c., and provided with control valves n. In order to prevent choking when dealing with materials such as damp coal, the separated material falling to the bottom of the flue may be received on a door u which, through the medium of linkage controls valves v. In the event of the feed stopping the door u closes and allows the valves to close, thus increasing the flow of air at the feed aperture. The small material carried away by the air current is deposited in a chamber j provided with baffles q and the air is discharged through a filter to the atmosphere or returned to the aspirator in a closed cycle.

Title: Improvements in apparatus for screw-threading pipes, rods and the like
IPC: B23G1/22
Filed: 1928-08-23
Abstract: 311,158. Jardine, J. V. Aug. 23, 1928. Screwing; dies and die-heads.-A machine having a non-rotating die-head for cutting taper threads on the ends of pipes &c. comprises a saddle 1 adjustably mounted on a bed consisting of bars 2 and slidably supporting the tubular stem 3 of the die-head 4. The die-head has radial dies 8 adjusted by levers 10 pivoted in a plate 9, the plate being removably connected by a screw 27, Fig. 1, to the outer casing 24 of the head to allow the levers to be disconnected from the dies for replacing the latter. The rear ends of the levers slide through a plate 12 having transverse pairs of pins 14, 15, and are given an arcuate shape so that movement of the plate 12 relatively to the head will cause the dies to be retracted slowly to cut a tapered thread. The extreme rear ends of the levers have steeply inclined surfaces which, in conjunction with the pins 14, 15, cause rapid opening and closing of the head. The head has lateral arms 5, 6 cooperating with the bars 2 to prevent its rotation. In operation, the saddle 1 is moved up to the work 35 which rotates in a sleeve 34 carried by a head 33 slidably mounted on the bars 2, and is locked by a catch 31. A hand lever 16, pivoted to the saddle and carrying a slidable rod 17, is actuated to cause a head 32 on the rod to engage the die-head 4 and bring the dies into contact with the work. The plate 12 is pressed towards the work by a spring 18 on a rod 19 attached thereto, the position of the plate and hence the diameter of the thread cut by the dies being determined by a set screw 21 adjustable in a head 20 on the rod and the setting being indicated by a pointer 22 on the head and a scale 23 on the saddle 1. As the cutting proceeds the plate 12 is maintained stationary by the rod 19 and set-screw 21, the levers 10 sliding through the plate and causing the thread to be tapered. When the desired length of thread has been cut the lever 16 is moved rapidly in a direction away from the work. causing the head 32 to engage the plate 12 and move it, against the spring 18, so as to enable the pins 14 to open the dies rapidly and then retract the head 4. On releasing the lever 16 the spring 18 returns the set-screw 21 into contact with the saddle 1 and causes the pins 15 to close the dies. A pointed cutter 30, Fig. 3, is slidable in grooves 29 of the tubular stem 3 by means of a hand lever 36 to enable burrs on the interior of the pipe to be removed.
