Abstract: 476,764. Sewing machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.) July 15, 1936, No. 19613. [Class] 112] A button-clamp for shanked buttons has a self-locking supporting arm and inter. changeable button-support. ing feet recessed to receive the shanks of buttons. The invention is illustrated as applied to a conventional button attaching machine. The clamp has the usual supporting arm 8 hinged to the machine. The arm has a downturned portion 8a providing a seat for any of a number of differently recessed button-supporting feet 12, Fig. 2, adapted to hold respectively buttons with shanks of wire or leather or integral shanks. The material m to which the buttons are to be secured is held on a suitable support 15 mounted on pins 17 projecting from the work - plate 19. The block 15 is adapted for blind stitching. Other blocks may be adapted for through stitching and may have a recess for a stay-button. Cooperating with the foot 12 to hold the button is an arm 20 with a cup-like head 20a for engaging the button x, in this case a wireshanked military button. The arm 20 holds the button shank x<1> in the recess in the foot 12. The head has two button-engaging portions 20b,. 20c. The arm 20 is adjustably mounted for horizontal movement on a part 21 pivoted on a screw 22 in the arm 8a. The arm 20 is clamped to the arm 21 by the nut 23 at a position suitable to the thickness of the button head. The arms 20, 21 are swung to open or close the button clamp by a lever 24 pivoted on the arm 8. The clamp is normally closed by the pressure of the coil spring 28 on the rod 29 carried by the lever. The arm 8 and its parts are normally held in operative position by the spring plunger 31, but may be swung upwards by the chain t and a treadle operated shaft. After the button has been attached, the initial upward movement of the button clamp breaks the thread and brings the head 29a of the rod 29 into engagement with the lower wall 4a of the machine causing the rod 29 to react on the rod 30 and depress the lever 24. This reacts on the lever 27 to cause it to travel down the wall 21b of the slot 21c in the arm 21, so opening the button clamp 20 to release the button. The clamp cannot be opened by the button owing to the positions of the pivot 22 and stud 27.

Filed: 1966-05-04
Abstract: 1,159,361. Inflatable grippers for handling loads. SOC. BERTIN & CIE. 4 May, 1966 [6 May, 1965; 17 Jan., 1966], No. 19691/66. Heading B8H. [Also in Division F2] A handling device comprises a plurality of parallel tubular inflatable members 3 attached at one end to a common support plate 1 and arranged to be inserted in or around a hollow article whereby the articles may be gripped on inflation of the members. The spacing of the members may be such that on inflation the members abut one another and are therefore selfbracing, or such that a common bar (33) or individual bracing bars (37), Figs. 5 and 7 (not shown), are required. In the latter case the members may be adjusted in radial slots (11) of the support plate (1) to accommodate different sized articles. The ends of the members are clamped to unions 5, 6, which unions are interconnected by a flexible rod 13 to partially relieve the stresses in the members due to the weight of an article. The members may also be clamped, intermediate their ends, to said rod 13. The air is supplied to inflate the members 3 through a pressure reducer 29 connected to an injector 19 which communicates through slots 22 and flexible pipes (17) with the union 5. The closure of a stop-cock 26 pressurizes the members 3, whilst the opening of the stop cock creates a vacuum by means of the injector and collapses the members for insertion and withdrawal from hollow articles. In an alternative embodiment a supply of pressurized air in a container (78), Fig. 6 (not shown), is mounted on the device, the container (78) also serves as a bracing rod for the members (3). The container outlet is sealed by a conventional ball (92) acted upon by spring (93) and air pressure, and a seating (94). The container is connected to the injector (19) by a tube (99) movable axially by the action of cam (108) whereby to depress the ball from the seating and release the air to pressurize the chambers. The stop cock (26) comprises a spring-biased hollow piston wherein depression of the piston vents the chambers to atmosphere and release of the piston closes the stop cock and pressurizes the chambers. In a further embodiment, Fig. 10 (not shown), the members are equipped with detachable shoes (60) with a resilient coating (61) with which to engage the article. In a further embodiment (not shown), two or more members are connected end to end to form a train whereby a series of articles may be moved, e.g. through a pipe. In a still further embodiment, for gripping articles externally, Fig. 14 (not shown), the members (3) are mounted on linked arms (70), (74), (75), (76) whereby they may be simultaneously moved towards or away from each other under the action of a pair of jacks (77) to grip the article (66). Plates (71) connected to the arms serve to brace the members (3).
