Original application filed September 4, isza'seriai No 6601793., Divide d and this application filed February 13, 19 26.-

This invention relates'to an improvement I for its object the provision of a machine hav ing an improved hopper and feeding means- This application is a division ofour Patent No. 1,597,932, granted August 31, 1926.

Hard candyin round stick forinpresents" many difliculties' in the Way of. wrapping the same by mechanical means, due to the fragile nature of the candy, and also to irregularity in size and shape of said sticks, even when of the same price-grade. V The present improvement aims to provide a machinefor feeding sticks of such various sizes and shapes as would likely be'encountered within thesame general price grade, and to handle such venthreakage thereof. 1

More particularly, the presentinvention is an improvement upon the stlck candy sticks in a manner suficientlygentle to pre Wrappingmachine described and shown in the patent toElmer L. Smith and Arthur E, Phelon, No. 1,597,931, granted August 31,

' 1926; In a general way, the operation of the i as present machine is similar to the machine of said Patent No. 1,597,931, and may be briefly outlined as follows. The candy st cks, usually ofround cylindrical form, are contained in a hopper which is provided with suitable agitating means, not hereinshown, 'for"causing' the sticks to be directed continuously into i downwardly directed spout.

stick at-a time from the outlet of said spout. A feed pusher engages each stick after it issues from said .spout outlet to advance the same against a Wra per and to advance said stick and wrapper into a tucking channel so as to partially wrap'the wrapper around the stick. Tucking mechanism may be arranged to then startthewr'apperfor a rolling o'pera tion-around the stick, whichrolling operation is effected by suitable rolling means into which the stick and; Wrapper are subsequently advanced. Duringhthe rolling operation,

7 portions of the wrapper which extend beyondfeach end of the stick are .engaged by end twisters. for twisting the same and thus securing the wrapper "permanently around the stick. From the rolling means, the

Referring to Fig.- 1, the rear or delivery end ofthe hopper isindi'cated at 2, it'being understood. that. said hopper is designed to contain a-plurality of sticks to be wrapped and to feed the same" continuallyto a down wardly directedspout 3. Below the outlet of said spout :is mounted a-receiver 4, pivoted at 5 on the main frame, and havlng alspring 6 connected to one end thereof tonormally. hold the receiving end of the same upwardly in yielding positiontoward said spoutout-' let. An adjustable stop pin 6 v limitsithe ac. Suitable escapement devices are proi idedto release onetion of said springi'6. Mounted for sliding movement past the outlet offsaidspout 3 is r a feed pusher 7 carriedonrodjs, which is sl dably supported in brackets such" as 16 fixed on said main frame. .The means for reciprocating the rod '8 are notldescribed, but I 9 maybe of any suitable character such as wall of said spout 3, is a rocking shaft 10. carrying a stop member 11 having a lower h'ookpo'rtion 12 extending through" an ,opening '11 in'said. spoutwallinto' the spoutipas sageway, for the purpose of engaging sticks and controlling the passage thereof through said. passageway, as hereinafter. described. 7 Fixed upon the shaft 1.0 i's an operating lever 13 adapted to be actuatedbv an. outwardly f extending h1g1; onsaid feedpusherf when 5 f omitting suchfeaturesfas will be understood 1 1 surface of said feed pusher 7 ingly mounted receiver 4.

A. spring 4 the feed pusher is in its advanced position, and preferably near the end of its forward stroke. A. spring 15 also connects said lever 13 with said main frame to normally hold the stop lever 11 in the. position shown in Fig. 2, whereby it engages a stick in said spout and stops the flow of sticks to the receiver 4. 1 V

The pusher 7 carries on its upper surface a soft resilient pad of rubberor the like 17, which pad lies directly beneath the spout outlet when said pusher is at the forward end of its stroke. Just previous to reaching the end of said forward stroke, the lug 14 carried on said pusher 7 engages lever 13 to release astick from said spout and allow the same to drop onto said pad 17. Upon the backward movement of said pusher 7, stop member 'll is returned by its spring 15 into engagement with thefollowing stickin said" spout, as shown in Fig. 2, and the previously released stick S is dropl'aedfrom the upper upon the yield- The feed pusher 7 is designed to thrust the sticks'on'e'at'atime with. a wrapper in advance thereof into a tucking channekwhich be formed with a bottom 18 and top 38. Thetucking channel may be arranged in a convexly curved path as shown to lead tangentially into a concavely curved wrapping bed, more fully described in the prior Patent No. 1,597,981, referred to.

The'yielding receiver 4 is preferably connected, as shown, by link 41.130 an actuating lever 28, said link 41 having free sliding movement in a downward direction through said actuating lever. Stop nuts 41 on said link 41 limit the upward sliding movement thereof-through. saidlever28. The actuating lever 28 ispivote'd at 42 upon the main irame and carries at its rear end .a roll 43 actuated by cam 44 rotatable on a shaft 45 mounted in themain frame. The cam 44 and actuating lever 28 are designed to periodically and temporarily pull down the forward part of receiver 4 and the rear end of said channel bottom 15%. Thislowering of said receiver andchannel bottom is arranged to take place at the time the feed pusher 7 begins the advance of a stick with a wrapper into said tucking channel and the purpose thereof is to relieve the stick of the necesslty of forcing Its way between the recelver 4 and fixed lip 46 of saidfoutlet'passage and between the bars at the mouth of said tucking channel, which might be the cause of breakage ofsaid sticks. 7 connecting the lever 28 to the main frame tends to keep thecam roll of said lever in engagement'with the cam 44 and a stop 48 on the mainframe is also provided to limit theupward movement of the forward end of said lever 28. i
