GEORGE B. ELL'INGWOOD, ()F MALDEN, MASSACHUSETTS, ASSIG-NOR TO THE WALTER M. LOWNEY COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

MERNEL-"FEEDING MACE-NINE.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed December 2. 1904. Serial No. 235,227.

To all whom, it may concern;

Be it known that I, GEORGE E. ELLINGWOOD, a citizen of the United States, residing at Malden, in the county of Middlesex and State of 5 Massachusetts, have invented a new and useful Kernel-Feeding Machine, of which the following is a specification.

- Machines have heretofore been made by which a kernelfor example, a nut or sugar filling-has been automatically covered with chocolate or the like. Such a machine is shown in Letters Patent of the United States to E. P. F. Magniez, N 0. 680,489, dated August 13, 1901. Heretofore, so far as I am I aware, the kernels have been placed upon a conveyer by hand and by it carried to the coating machine.

The purpose of my present invention is to enable the kernels to be fed automatically to 0 the coating-machine at a proper distance apart, so that when reaching the coating-machine they will be in such position with relation to each other as to be properly coated with chocolate. For this purpose I have provided a hopper in which the kernels may be put, a feeding-shaft or other means whereby the kernels may be taken in proper quantities therefrom, and means to guide the kernels so taken down into position upon a conveyer or 3 the like, by means of which they will be fed automatically to the coating-machine.

My invention will be understood by reference to the drawings, in which- Figure 1 is a plan, a portion of the mech- 3 5 anisms being broken away to make the construction more clear. Fig. 2 is a longitudinal section on line 2 2 of Fig. 1. Fig. 3 is a side elevation of the hopper, &c., upon a larger scale than Figs. 1 and 2. Fig. 4c is an 4 end elevation; and Fig. 5 is a similar View,

differing therefrom mainly in the removal of the guides.

A is the frame of the machine, which is suitably supported and comprises a slanting bed a and suitable side beams wherein the various shafts, &c., are mounted. Upon the bed a runs a conveyer 6, passing around a drum on a shaft B and also passing over the end of the bed a. This conveyer is of sub- 5 stantially the width of the bed a. It is moved by power applied to the shaft B by means of the sprocket 5, upon which runs a chain belt 6 which also passes around the sprocket 6,

carried by a stud projecting from the side frame a and sprocket Z7 on the shaft 5 and which passes a chain belt 0 to the sprocket c on the end of the feed-roll C, an idler c adjustable, as shown in Fig. 8, being used as a belt-tightener.

The feed-roll C is preferably made of wood and has a series of grooves in its periphery running lengthwise of the roll deeper at their rear than at their front ends, as shown in Fig. 2, so that the kernels which are fed into the hopper D will fall into the grooves as they pass under the bottom of the hopper and will be held therein and at the proper time will slide out therefrom onto the apron or guide provided for the purpose and to be described below. The hopper D is located above the feed-roll C and has an opening at its bottom, which opening is closed by the feed-roll C. A brush (Z forms one edge of the opening in the hopper. This brush is preferably made fairly stiff and strong and runs the length of the hopper. The holder for the bristles or other flexible portion of the brush is preferably a pair of metal bars bolted together, the ends of the flexible portion of the brush being held between them, one of these bars having an ear cZ near each end extending out therefrom at right angles thereto, each ear having a threaded hole therethrough in which turns a screw (Z which first passes through an ear (Z riveted or otherwise attached to the wall of the hopper. Each screw is provided with a suitable head and set-nuts (2*, whereby when once adjusted it will remain in place. It will be noted that the brush (Z is so located that the feed-roll C will turn toward it, and it is so adjusted that it will nearly or quite touch the surface of the roll, its purpose being to keep the roll from carrying out from the hopper any kernels except those located within the feed-grooves in the feed-roll. it is partly for this purpose that each groove has its rearward side made substantially radial of the feed-roll, as otherwise the kernels might be brushed out from the grooves as the grooves pass under the brush.

Below the feed-roll is located an inclined apron E, made preferably of sheet metal, provided with ways 6, separated by ribs 6, which guide the kernels received therefrom down to the conveyer 6. It is also to be noted that the ribs are so located that the ways formed between them are contracted in the direction toward the conveyer, which acts to confine the kernels toward the ends of the ways, with a tendency to make them pass onto the conveyer individually or in single line. This apron is supported from a cross-bar 0 by means of straps 0 6 attached to the under side thereof, the ends of the cross-bar 0 passing through slots 6* in the hopper-support D, whereby the bar, and hence the upper end of the apron, may be adjusted with relation to the roll and clamped in place, By this mode of adjustment the inclination of the apron may be changed, which controls, of course, the rapidity with which the kernels may slide or gravitate along onto the conveyer. The apron is sufficiently long to deliver its contents upon one end of the conveyer 6. By this means the supply of kernels is controlled.

In order to insure the kernels being arranged more or less symmetrically, so that they will be properly presented to the chocolate-covering machine,there are shown shakerbars f, the lower ends of which are pivoted at f to astationary cross-bar f their upper ends reaching to meet the ribs 6 in the apron E. They are pivoted at their upper ends to a jigger-bar F,'which is given a slight vibra tory movement, such as to move the shakerbars f slightly about their pivots f. The jigger-bar F is supported upon the side beams 0/ of the frame A, being held in place by straps f and being vibrated by means of a rocker-arm fi attached to a rock-shaft f, supported in bearings f, attached to the side a of the frame A, the lower end of this rockshaft carrying a rocker-arm the end of which is given the necessary short rocking movement from the rod f running the length of the machine and operated by a crank-shaft (not shown) lying beneath, parallel with, and operated from the shaft 6 The connection between the jigger-bar F and the rocker-arm f, as shown in Fig. l, is by means of a bolt passing through slots in the rocker-arm and an arm F, carried by said jigger-bar in order that the length of throw of the parts f may be adjusted according to the character of the kernels to be fed.

The apparatus above described, while simple in construction, has proved efficient and economical, as it requires no attention other than that which can be given to it by the operative who runs the chocolate-coating machine, so that the coating can be done by one operative instead of two or more, as has heretofore been the custom. The shape of the feeding-roll and the general arrangement of the parts may be altered somewhat, according to the size and shape of the kernels to be fed, the novelty of my invention lying not in the shape of the various parts, but in their general arrangement, whereby a line or series of kernels will be received from the hopper and delivered to the shaker-bars and the conveyer upon which the shaker-bars are caused to slide laterally by the jigger-bar in such manner that they are in substantially the proper relation to each other to pass to the coatingmachine. It is apparent that as the kernels are not held positively they are liable to be fed more or less unevenly; but any such irregularity of feed is slight and can easily be corrected by the operative.

In using the term kernePI mean to be understood as including any substance which is or may be covered by melted chocolate or the like viscous substance.

The apron may be provided with a suitable cover, if thought best.
