Abstract: 526,766. Nailing ; shoe-making. UNITED SHOE MACHINERY CORPORATION. March 21, 1939, No. 8898. Convention date, March 22, 1938. [Classes 17 (ii) and 89 (iii)] A machine for inserting headed fastenings into workpieces is provided with means for removing part of the head while the fastening is being driven. In the case of a lasting machine such as is described in Specification 14453/97, [Class 17], a part may be removed at both sides of the head, Fig. 4, the fastening being driven with the bar-like head which remains lying parallel to the edge of the shoe bottom. For through-sewn shoes, only the side of the head adjacent to the edge of the shoe bottom need be removed. As described in a lasting machine, the tack block and wiper 12 is provided with a transverse slot 28, 30 in which two blocks 34, 36 are slidable and are biassed inwardly by springs 38, 40. Each block provides half of a tack passage which is conical at its upper end 56 and cylindrical at its lower end 58, and carries an extension 60 or 64 formed with a cutting edge 62 or 66. When the blocks are assembled in the slot 28, 30, the cutting edges are spaced apart a distance about equal to the diameter of the shank of the tack. In the use of the machine, a tack is fed to the tack block so that its head is supported in the conical part 56 of the tack passage. When the driver 18, which has a thickness about equal to the diameter of the tack shank, descends, it causes the tack head to spread the blocks 34, 36 apart, so that opposite side portions of the head are cut off by the cutting edges 62, 66 as the tack descends through the part 58 of the tack passage. The severed portions of the head fall down inclined passages 52 and pass out of the tack block. The passages are covered by parts 48 of the springs 38, 40. Inward movement of the blocks 34, 36 is limited by shoulders 76, 80, and the tack block has a cover plate 82 with a slot 92 for passage of the driver.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/08
Filed: 1931-03-26
Abstract: 361,785. Photographic shutters. KODAK, Ltd., Kodak House, Kingsway, London.-(Assignees of Mihalyi, J. ; 333, State Street, Rochester, New York, U.S.A.) March 26, 1931, No. 9236. Convention date, March 28, 1930. [Class 98 (i).] A photographic shutter of the kind in which a blade or plate is moved over an aperture through which light passes to make the exposure comprises a pivoted actuating trigger so connected to the shutter blade through a spring that when the trigger is actuated in one direction about its pivot the blade is moved forward by means of the spring to make the exposure, and when the trigger moves in the reverse direction on the forward movement of the blade is continued to its initial position. As shown in the Figure, an actuating trigger 16 pivoted at 21 is controlled by a spring 17 which tends to maintain the arm 18 of the trigger in engagement with a flange 19 on the shutter plate 20 screwed to the front plate 1. The actuating trigger has two arms 22, 23, the arm 22 carrying a stud 24 to which is pivoted one end 25 of a spring 26. The other end 27 freely engages a stud 28 carried by the shutter blade 4. Substantially diametrically opposite on the blade 4 are two teeth 31, 32 and immediately behind each tooth are two lugs 33, 34 respectively, the lug 33 being farther from the tooth 31 than the lug 34 is from the tooth 32. A spring pawl 37 carried on an extension 36 of the shutter plate 20 has a curved end 38 co-operating with the teeth 31, 32 to prevent counterclockwise rotation of the blade 4. The second arm 23 has a channelled end co-operating with the lugs 33, 34. For an instantaneous exposure, the trigger 16 is depressed against the action of its control spring 17 whereby the arm 22 moves upwards and tensions the spring 26. When the arm 23 moves clear of the lug 34 the shutter blade 4 rotates to make the exposure. The tooth 32 is now engaged by the pawl 37. When the trigger 16 is released the spring 17 turns the trigger back and tensions the spring 26, though not enough to cause the lug 33 to move out of the path of the arm 23 so that the lug 33 passes.into the channelled portion of the arm 23. Continued movement of the arm 23 results in the lug 33 riding clear of the outer end 41 of the wall 40 whereby the blade 40 is released and again rotated in the forward direction to the initial position. For a time exposure the lever 11 is drawn out so that the lug 14 is moved into the path of the lugs 33, 34. On depressing the trigger 16 the blade 4 rotates until the lug 34 engages the lug 14, when the arcuate opening 30 registers with the opening 3. On releasing the trigger 16 the blade 4 rotates backward and the lug 34 passes over the outer end 41 of the wall 40 by which the lug is then retained. A cable release 42 engaging the arm 18 of the trigger may be employed. A lever 9 positions different stops in front of the opening 3.
