To all whont it may concern;

Be it known that l, EDWARD SHAW, a subject of the King of Great Britain and Ireland, residing at London, England, have invented Improvements in Vending-Machines, of which the following is a speciiication.

This invention relates to automatic vending-machines of the kind in which goods are delivered from bulk and at the same time a piece of paper is supplied in which to wrap the gods bought. In a machine according to this invention the paper passes between two feed-rollers, one of which is partially rotated at each machine operation by suitable means. The second roller is then driven from the machine-operating shaft and a movable cutting-blade is released and is drawn down at the completionl of the rotation of the feedrollers and cuts E a strip of paper.

Figures 1 and 2 of the accompanying drawings showin rear elevation and in plan paper feeding and cutting-olf mechanism according to this invention with portions of the machine-operating mechanism. Figs. 3 and 4 are opposite end elevations. Fig. 5 is a section corresponding to the line V V of Fig. 1. 1 is a longl strip of paper the free end of which first passes between rollers 2 3, mounted in standards 4, then between guide-plates 5, also carried by the standards 4, before passing between a fixed scissor-like blade 6 and a blade 7, pivoted to one of the standards 4. The blade 7 is moved down and up after a given length of paper has been fed forward by mechanism that is actuated from one arm vof a lever 9, whose other arm is connected to the machine-operating shaft 12 by means of a link and crank-disk 11.

The rollers 2 3 are geared together at 13 and are driven as follows: Upon the spindle of the roller 2 is mounted a ratchet-wheel14, with which engages a weighted pawl 16, carried by an arm 15, loosely mounted on the roller-spindle and operated, through a bellcrank lever 17, link 18, and arm 19, from a shaft 20, that is partly rotated 4by means of an inserted coin each time the machine is operated. Upon the spindle of the roller 3 is a mutilated ratchet-wheel 21, with which engages a pawl 23, carried by an arm 22, loosely mounted on the roller-spindle and operated from the lever 9 through a link 24.

The pawl 23 when the machine is inoperative rests upon the portion of the ratchetwheel 21 that is without teeth, Fig. 4. When the machine is operated, the shaft 2O is partly rotated. This partial rotation causes the pawl 16 to Iact on the teeth of the ratchet-wheel 14 and drive the roller 2, which through the gearing 13 drives the roller 3. The rotation of the roller 3 brings the teeth on its ratchetwheel21 and the pawl 23into engagement. The rollers 2 3 are now driven by the pawl 23 from the shaft 12 until the pawl 23 again comes in contact with the plain portion of the ratchetw heel. The shaft 12 is rotated until the quantities of goods paid for has been delivered. The pawl 16 serves only to move the rollers through such an angle as will bring the pawl 23 into engagement with the toothed portion of its ratchet-wheel.

The blade 7 is normally kept in its raised position by a detent that comprises a short lever, one arm of which" is formed with a jaw 27, that engages a pin 26 on the blade, and the other arm of which is formed with a tooth 28, that is engaged by the hooked end of a lever 29, pivoted at 29% to the one of the standards 4.

30 is a spring-pressed arm, which is connected to the spindle of the/roller 3 by a pin 31, which projects from a collar on the spindle into a slot 32 in the arm. The arm comes in contact once in each revolution of the spindle with the lower portion of the lever 29 and causes the release of the, detent. Depending from the blade 7 is a bar 35, suitably guided by a part 36, that is fixed to the standard 4 and passes through a long slot 37 in the said bar. Normally the upper blade 7 is held raised, and the lower end of the bar is caused by a spring 38 to assume a position in which its lower end will be clear of the lever 9. Projecting from the lower arm of the lever 29 is a .pin 39, which when the lever is actuated comes in contact with the bar 35 and pushes it into such a position that the lever 9 upon its next upward movement slides past a spring-pawl 40, carried thereby, and upon its next downward movement the lever 9 comes in Contact with the spring-pawl 40,

and thereby pulls down the blade 7, which shears off the length of paper. When the bar 35 is pulled down, its upper part, which is of reduced width, comes opposite the pin 39 and permits the lower end of the lever 29 to be moved still farther outward and the arm 30 under the action of its spring to move clear of the lever 29. The spring 38 then forces the bar 35 back to its normal position, so that upon the next upward movement of the lever 9 it will come in contact with a projecting portion 41 of the depending bar 35 and lift the blade 7 into its raised position, wherein it will be held by the detent 27.

yThe circumference of' the roller 3 issuch as to cause the desired amount of paper to be fed at each revolution.

In proximity to the rollers and below the pan 42 of a weighing device into which goods are deposited-is a goods-delivery passage consisting of a frame 43. The paper is fed forward so as to rest upon guides 44 over the mouth of the delivery-passage 43. Upon the completion of a machine operation the pan 42 tips and the goods drop upon the cut paper and cause it to fall, with the goods thereon, through the delivery-passage 43, the shape of' which is such as to cause the paper to more or less inclose the goods.

It may sometimes be desirable to support the paper as it is fed forward on the guides 44, for which purpose an arm 45, Fig. 2, that projects from a carriage 46, which is adapted, by means of a pivoted lever 47 and an operating-arm 48, pivoted to a crank-pin 49, secured to one of' the gear-wheels 13, to be moved along a fixed bar 5() as the paper is fed forward.
