IPC: D03J5/24
Filed: 1918-12-14
Abstract: 136,612. Wood, A., and Wood, G. Dec. 14, 1918. Shuttles.-In shuttles having a guide-member arranged within a recess to rise and fall to uncover and cover the entrance to a tangential threading-slit extending to the eye, means are provided for creating a variable drag in the weft. Within a recess in the shuttle is arranged an inverted hollow cone d, Fig. 3, normally held down by a spring f, but adapted to be raised to admit the weft for threading by pressing on a head e' or on a lever within an opening in the lower face. The weft is tensioned by pins k<2> carried by the cone, between which and a bar l on a spring blade, or on an adjustable slide m, the weft passes. The slide m is clamped by a slotted plate n, which is adjustably secured by a screw o and nut p rotatable by a special tool. In another form, the plate q, Fig. 7, serves to cover the slot entrance, and is supported on a pin s carried by a plate t. To the underside of the plate q is attached a glass or like roller u, roughened on half its surface, against which the thread bears. More or less of the roughened part may be presented to the weft. A slotted keyed plate v assists in the laying of the weft round the guide-member q.

Title: An improved feeding device for delivering metal to the pots of type casting and like machines
IPC: B41B11/82
Filed: 1930-07-11
Abstract: 356,863. Charging-apparatus. HARTMANN, C. W., Lyngby, near Copenhagen. July 11, 1930, No. 21009. [Class 51 (ii).] Relates to devices for supplying metal to the metal-pots of type-casting and like machines, of the kind in which a toothed bar of type or other metal is fed downwards into the metal-pot stepby-step by feed-mechanism operated by the movement of the pot, and rendered inoperative by the action of a float when the level of molten metal in the pot rises sufficiently. The metal bar is contained in a vertical tubular guide 3, Fig. 1, mounted on the cover 1 of the metal-pot, and is formed with a longitudinal recess 18, Fig. 6, having on opposite sides ratchet-teeth 19, 20, which are engaged by a dog 17 on a bar 12. Fig. 1, mounted to slide horizontally on the guide 3. To the bar 12 is pivoted a lever 8, the end 8a of which engages a fixed abutment when the metal-pot moves, whereby the bar 12 is shifted and the dog 17 permits the metal bar to descend one step. The return of the bar 12 is effected by the cam action of the ratchetteeth 20. The opposite end of the lever 8 rests beneath a finger 10 connected to a float 4 and adjustable vertically. The rise of the float above a predetermined level allows the lever 8 to rock by gravity, so that its end 8a is moved out of alignment with the fixed abutment, and the metalfeed is stopped. The fixed abutment may be adjustable vertically and axially, and has a,n inclined operative face with a notch or recess to ensure engagement with the end 8a.

Filed: 1927-08-16
Abstract: 281,582. Wellcome Foundation, Ltd., Henry, T. A., and Sharp, T. M. Aug. 16, 1927. Alkaloids from the seeds of Picralima Klaineana, Pierre, are obtained and separated into three alkaloids referred to as A, B and C. The ground seeds are freed from fat and extracted with ethyl alcohol. The extract is dried and again extracted with dilute hydrochloric acid, clarified with charcoal and filtered. If the filtrate is made akaline with sodium carbonate the total precipitable alkaloids are obtained. If, however, the filtrate is first carefully diluted with water a portion of alkaloid A is precipitated and a further precipitate is then obtained by adding alkali. This precipitate can be separated into ethersoluble and ether-insoluble portions. From the ether-soluble portion alcohol dissolves out alkaloid B and leaves alkaloid C, and the etherinsoluble portion is alkaloid A. The three akaloids may be further purified by any of the ordinary processes.

Abstract: 302,614. Molins, W. E. Aug. 18, 1927. Paper bags, making.-In a machine for making and filling cigarette and like containers comprising a pair of pockets hinged together as shown in Fig. 13, the pocket, forming one half of the completed packet, is formed from a blank B, Fig. 12, on a rectangular plunger 3. Figs. 1 and 2. and stripped therefrom by mechanism, which may be as described in Specification 1116/11. The blanks B are fed from magazines 16 alternately by suction feeds 17, such as are described in Specifications 24306/14, 24307/14, and 24346/14, [all in Class 100 (i), Feeding and delivering webs &c.], to continuously rotating rollers 8 beneath a. high speed roller 9. The blank is raised into contact with the roller 9 by a roller 10 on an arm 11, Fig. 2, rocked by a pawl 14 adapted to be engaged by a boss 13 on the plunger 3 during the upward movement of the latter. This results in the blank receiving a sharp impulse which feeds it into position against a stop 21 ready for the descent of the plunger. The edges of the blank may be gummed during the feed. The plunger descends and carries the blank through folding and stripping mechanism so that a pocket is formed having an extension b on one broad side at the open end. The pocket is stripped from the plunger and is thrust into a heater box 23 by a member 24, and are intermittently fed to the right, Fig. 1, while the adhesive dries. The leading pocket is then turned through a right angle into a magazine 28 in the manner described in Specification 166,406, and arrives on the bed 2 of the machine. After being filled, a pair of pockets are secured together as shown in Fig. 13. The double packet may be formed without being filled by cigarettes, in which case the conveyer 45 feeds formers into the pockets. The formers are subsequently removed and the packets filled by hand. In another method of operation, the gumming may take place after the insertion of the cigarettes.
