Title: Means for packaging yarns and thread material of all kinds
IPC: B65H54/82
Filed: 1954-10-18
Abstract: 754,809. Coiling yarns. ERB, E. Oct. 18, 1954 [Oct. 20, 1953], No. 29893/54. Class 120 (3). [Also in Group XVII] A machine for coiling thread comprises in one form, Figs. 1, 3 and 4, a rotary spindle 12 through which the thread 6 passes to a guide 7 carried by a bell 10 mounted on the spindle, a pair of oppositely-threaded members 4a, 4b carried by spindles 21, 22, rotatable in a housing 18 journalled on the spindle 12, and a cylindrical container 3 carried by a rotary shaft 3a and fitted with a slidable bottom plate 5 urged upwardly by a spring 5c. The shaft 3a is slidable vertically by the operator and is located in its upper and lower positions by the engagement of a pawl (not shown) in a groove 3d or 3c. In its upper position, the mouth of the container embraces a fixed cover-plate 14 formed with an opening 15 through which the ends of the members 4a, 4b project. The spindles 21, 22 and 12 are interconnected by gears 23-26 and the housing 18 is prevented from rotating by rollers 8, Fig. 3, engaging the members 4a, 4b so that, as the spindle 12 rotates, the guide 7 lays the thread in the uppermost grooves of the members 4a, 4b and the latter are rotated in opposite directions to convey the coils thus formed downwardly towards the surface of the plate 5. The lower ends of the members are formed with inclined surfaces 29 so that each coil is finally deposited on the surface of the plate 5, the latter moving downwardly against the action of the spring 5c as successive coils are deposited thereon to form a stack of coils overlapping in spiral formation. The coils'are retained on the members 4a, 4b by a rubber roller 9, Fig. 3, co-operating with a leaf-spring 17. When the container 3 is full, it is lowered to enable the stack of coils to be ejected into a packaging container. In modifications (not shown) four or six conveying members are provided, alternate members having threads of opposite hand and rotating in opposite directions. In a second form, Fig. 8, the members 4a, 4b are replaced by three endless conveyer bands 48 formed with transverse grooves which receive the coils of thread. The bands pass over pairs of rollers 54 and similar rollers driven through worm gearing from the spindle 46 corresponding to the spindle 12. A fixed plate 56 has an upwardlybent end 55 which passes between one pair of rollers positioned slightly lower than the others and serves to deposit the coils in succession on the plate 5.

Title: Improvements in coin freed automatic machines
IPC: G07F17/34
Filed: 1919-12-01
Abstract: 161,224. Jackson, J. Dec. 1, 1919. Delivery of articles stored in piles; coin action, mechanicalconnection and weight. -The machine delivers a number of different articles in a sequence which is unknown to the purchaser. After insertion of a coin in the slot; 6, Fig. 1, a handle 7 is turned to wind up a spring or weight motor, as described below, and, on completion of a full stroke of the handle, the motor is freed and moves a pointer 4 over a dial 3 through a predetermined angle to indicate the nature of the article to be delivered. At the same time the coin is released and passes to the delivery apparatus, where it acts by weight to release the drawer 8 which may then be pulled out. Means are provided to prevent return of the drawer when only partly opened, to prevent re-opening of the drawer when partly closed, and to close the drawer by a spring after it has been partly closed by hand. Fig. 2 is a rear view of the interior of the casing. The coin shoot 9 has an extension 10 mounted upon one arm 11<a> of a bell-crank 11, pivoted at 12. The coin C passes to the bottom of the shoot 10 and rests upon a rack-plate 13, as shown, in which position it forms a connection between the bellcrank 11 and a bent arm 15 operated by the handle 7 and controlled by a spring 17. The arm 11<b> of the bell-crank is connected to a chain 26 which passes over a sprocket-wheel loose on a spindle 22 and supports a weight 27. A pinion 21 on the spindle 22 drives a pinion 20 on the spindle 5 of the pointer 4. A ratchet pawl connects the sprocket-wheel to the pinion 21 when the weight 27 falls. A pawl 30 normally prevents clockwise rotation of the spindle 22, Fig. 2, and a second pawl, not seen, prevents counterclockwise rotation. When the handle 7 is turned, the bell-crank arm 11<b> is raised and the weight 27 is lifted; a lug 33 on the chain 26 frees the pawl 30. At the end of the bell-crank stroke, the coin C falls from between the arms 15, 11<a> into a shoot 18 leading to the deliverymechanism. The bell-crank is thus freed and the weight 27 reacts, causing clockwise rotation of the sprocket-wheel and consequential rotation through a definite angle of the pointer 4. The coin, by its weight, releases a pivoted locking- pawl controlling the drawer 8, which may then be opened. A weighted pawl, hanging vertically, co-operates with a rack-bar on the underside of the drawer, and is tilted during opening so as to prevent closing until the rack moves clear of the pawl. During closing, the pawl is tilted in the opposite sense, and prevents re-opening. A spring-actuated lever arm engages a lug on the drawer when the latter is partly closed, and completes the closing.
