The article c, Fig. 3, is placed on a table 6 so as to overlap a wrapper a which has been fed auto matically or placed by hand in the position shown. A rod 4, the ends of which engage in endless tracks 3 at each side of the machine, is raised by arms (not shown) to the position A from which it falls by gravity through the path A, B, C, to the starting point D, thus lifting the rear end of the wrapper and causing it to en circle the article. The rod, in its path, brushe aside a light spring 21 which springs back to clip the free end against the underside of the table 6 Pinions 5 at the ends of the rod may be provided to mesh with teeth on the side plates to ensure that it remains horizontal. A rotating arm 24 Figs. 3 and 5, moves the article on to a table 22 folding up the end of the wrapper so that an overlap is formed at f. Tucking plates 28 on arm 29 descend and turn down the projecting end portions g, and plates 34, 34<a> turn into the positions shown in Fig. 7 to make the folds h Plates 36 turn the projecting flaps up beneath the table 22, and the package is pushed by succeed ing ones on to a plate 43, which may be heated so that, when waxed paper is used, the flaps are caused to adhere. The package arrives in a delivery shoot, shown in plan in Fig. 15, com prising a base of rollers 45 and spring sides 44 The various parts of the machine are adjustable to accommodate different sizes of articles and the parts 28, 34 may be resiliently mounted.

The loopercarrying shaft 44 is oscillated by an eccentric connection 58 to the eccentric 54 which drives the cranked end of the looper-shaft 44. Alternatively, the depending arm 49 may be forked and slotted and the pivoted connection of the link 48 and arm 49 may be adjusted by a screw in a slot to vary the throw imparted to the looper shaft. The timing of the loopers can also be varied. Frames.-The work supporting arm 4, Fig. 8, may be provided with a dovetailed shutter 68 fastened by a spring catch 69 to render accessible the connections between the operating parts. The invention is described as applied to a feed off the arm machine but is also stated to be suitable for feeding work on the arm, and an auxiliary feed-dog and feed-bar receiving movement from the main feed bar may be provided if differential feed is required.

Abstract: 506,643. Optical-projection apparatus; electric switches. ANCIENS ETABLISSEMENTS BARBIER, BENARD, & TURENNE. Nov. 29, 1937, Nos. 32896 and 32897. Convention dates, Nov. 30, 1936 and July, 28, 1937. [Class 97 (i)] [Also in Group XXXVII] A horizontal supporting plate 6 carries transparencies to be projected by a microscopic projection apparatus, the transparencies 11 being carried on discs 10 rotatable in and removable from the plate 6 which is rotatable about a pivot 8 to position the transparencies successively on the axis of the projection apparatus. The plate 6 rests on a lower coaxial plate relatively to which it can rotate, and the pivot pin 8 is carried on a slide 29 movable by a rod 43 to position each transparency accurately. The position of the plates are determined by spring-pressed pins on the lower plate engaging notches in the upper plate, small rotations of the plate being effected by a pin movable in an inclined slot 53 in the lower plate by a screw 50. To facilitate location of the preparations 11 they carry lines 16 registering with corresponding lines on the discs 10. The Specification as open to inspection under Sect. 91 describes also the subject-matter of Specification 499,291, and also focusing-mechanism for the projector which may be fitted with an eyepiece to permit direct observation with or without simultaneous projection. As shown in Fig. I (Cancelled), the objective is carried on a piston 36 sliding in a cylinder 37 under the action of a spring 38, the cylinder being filled with liquid and connected by a pipe 40 to one or more screw pistons 42 which effect the focusing. Interchangeable objectives 47 and 48 are provided. Alternatively, as shown in Fig. 4 (Cancelled), the objective is carried in a tube 100 dovetailed in a slide 101 movable in a vertical quide and carrying a pinion 104 engaging a rack 103 on the tube 100 to permit rapid focusing. The slide 101 is pressed by a spring 106 so that a roller 107 thereon engages a cam 108 rotated through suitable gearing by an electric motor 116 to permit remote control of the focusing. A reversing switch, Fig. 10 (Cancelled), for operating the motor comprises a sliding plate 130 having projections 133, 134 so that in one extreme position two pairs of contacts 123, 125 are closed to. rotate the motor in one direction, and in the other position the other pairs of contacts are closed to reverse the motor. This subject-matter does not appear in the Specification as accepted.

Abstract: 604,845. Drum brakes; adjusting brake shoes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Dec. 6, 1945, No. 32970. [Class 103 (i)] Retracting-means for the shoes of brakes of the kind in which shoes 2 are applied to a drum 1 by a member 4 expansible by fluidpressure and mounted on a fixed annular support 3 include a device for adjusting the shoes for wear comprising two members coupled together as by friction and arranged to be displaced relatively to each other if the application movement of the shoe exceeds a predetermined amount. In Fig. 4, the shoe 2 is retracted by a coil spring 7 bearing on the support 3 and on a split-collar which grips the pin 5 secured to the shoe. In an application the pin is pulled through the collar if due to wear the shoe is moved further after the spring has been completely compressed, a constant clearance of the shoe from the drum, in release being thus maintained. In another form, each pin 5 extends through and frictionally engages a shoe-retracting blade spring, the ends of which bear on the inner surface of the support 3. In an application, the spring is deflected and if, after its middle part also bears on the support, the shoe moves further, the pin is pulled through the spring. In a further form, Fig. 6, the shoe is released by a spring 15 bearing on a fixed bracket 14 and on a transverse member 10 connected to the pins 5. A pin 13 is gripped by the split boss 11 of the member 10 so that if the application movement of the shoe exceeds the normal clearance between the head of the pin 13 and the support 3 the boss 11 moves over the pin. In a form described in the Provisional Specification, a volute spring bears with its largest and smallest diameter coils respectively upon the annular support and upon a split sleeve or coil spring, which grips the pin connected to the shoe, the pin being pulled through the sleeve or coil spring if in an application, the shoe movement exceeds that required to engage the small diameter coil with the annular support.

In a carbon dioxide pump an annular recess 9, surrounding the pump plunger 2, is connected through a passageway 12 with the container for supplying the liquid, carbon dioxide to be pumped. The carbon dioxide gas under pressure present in the recess 9 prevents liquid carbon dioxide which leaks from the pumping chamber 5 from solidifying. Glands 10 and 11 surrounding the pumping plunger restrict carbon dioxide leakage. The gas in recess 9 may be produced by vaporization of liquid carbon dioxide supplied to the recess.
