Abstract: 563,821. Caulking. AIRCRAFT SCREW PRODUCTS CO., Inc. May 7, 1943, No. 7254. Convention date, June 24, 1942. [Class 83 (iv)] An expanding and caulking tool, particularly adapted for securing wire helices in hollow bodies to act as the threads of a nut, comprises a hollow member having a central expansible portion and a movable core member to effect the expansion. The caulking tool slides on one end of the hollow member. The hollow member has a central section 14, threaded to correspond with the bolt member to be used with the helix 15, and cylindrical end portions of reduced diameter. A number of slots 23 extend through the part 14 and for a considerable distance on each side to provide for expansion by the coned end 25 of a core member 26 engaging a conical section 21 of the bore of the hollow member which is tapped to engage a threaded part 27 of the core and formed to hexagon shape at 17. Lock nuts 29 limit the expansion. The caulking tool 30 slides on the unslotted end of the hollow member with a sufficiently good fit so that the air enclosed in the space 34 acts as a cushion to prevent accidental damage due to the oblique teeth 32 on the end of the tool striking the threaded portion 14 when the tool is not in use. The tool 30 is chambered out at 35 to allow for the expansion of the hollow members. The helix 15 is screwed into place so that the last turn passes below the first teeth of the thread in the part 16. The hollow member is then screwed in, as shown in Fig. 4, and expanded to hold the helix firmly seated and in place. The caulking tool is then manipulated to set down the first turn of the thread securing the helix in place. The tool may be employed for staking an annular groove around a lined hole of any member. In a modification, the bore of the tool 30 is of the same diameter throughout and expansion of the hollow member is allowed for by reducing the diameter at 135.

Title: A new or improved drag or tensioning motion for yarns as they are being wound in winding machines
IPC: B65H59/12
Filed: 1923-03-15
Abstract: 216,963. Marsh, J. H. March 15, 1923. Tension arrangements. -In a device for applying tension to a yarn x, the yarn is led through guides 15, 16, 17 and passes completely round a wheel 12 mounted on a shaft 19. A centrifugal governor device comprising arms 22 and balls 23 is mounted on the shaft 19, the ends of the arms 22 being attached respectively to collars 20, 21 fixed on the shaft, and a collar 24 slidable thereon. The collar 24 is provided with a brake-disc 29, and a brake-pad 37 is arranged on an arm 30 which latter projects from a member 31 as shown in the Figure. When the yarn is being wound, it rotates the wheel 12 and thereby the governor, and the collar 24 rises on the shaft 19 until the disc 29 contacts with the pad 37, the disc 29 and wheel 12 thereupon settling down to a steady speed, which, being less than the linear speed of the yarn, puts a tension thereon. The position of the pad 37 can be adjusted by the wheels 42, 34 and the screwed member 31, so as to vary the tension on the yarn, while a series of tension devices can be mounted in one frame and adjusted simultaneously. If the yarn should break, the guide 7 is arranged to drop and make contact with a member 39 which stops the device by friction against the collars 20, 21. The same yarn may be led round more than one wheel 12 to obtain a greater surface contact.

Heading H2J. In a remote control system for electric motors, relays 2 and 3 are initially supplied with alternating-current from a tapped transformer 1, and the relays do not operate. Closure of a push-button 5 introduces a diode 4 in parallel with the relays which are then supplied with pulsating direct current to operate the relays. Relay 2 energizes a starter for a motor, and contact 6, of relay 3, shunts the push-button 5. The motor is stopped by actuating push-button 7. Another motor is started by actuating pushbutton 5<SP>1</SP> which is associated with relays 2<SP>1</SP> and 3<SP>1</SP>. Short-circuiting between leads 8, 9 or 10 cause the relays to drop-out. In another arrangement, actuation of a pushbutton introduces a starter diode in parallel with the relays 2 and 3. A contact of relay 3 is changed-over to shunt the push-button and starter diode, the rectified current then passing through the diode 4, Fig. 2 (not shown).
