Application June 24, 1952, Serial No. 295,251 1 Claim. (Cl. 107-10) This invention relates to improvements in a machine for rolling a sugar batch serving to make candies, the batch lying on revolving conically shaped rollers. In the manufacture of lilled candies the batch generally consists of a tough, dough-like coat of sugar enclosing a lling of marmelade, marzipane, nougat, kor the like. When processing such a mass, it often occurs that the filling penetrating the sugar coat smears the rollers of the machine. The rollers must be cleaned with water and dried very carefully after cleaning, as traces of moisture will cause the sugar to stick to the rollers. The cleaning and drying in the machine of the rollers, however, is diflicult, and takes much time.

To overcome these disadvantages I suggest providing each roller, at one end, with a bearing and pivot hingedly connected to it, and at the other end, in a conventional manner, with a bush for receiving a spherical journal with a tappet. In this Way it is possible for the rollers to be removed from the machine without using tools, and it is no longer necessary for the rollers to be cleaned within the machine. Outside the machine such cleaning can be done very quickly and easily and, above all, the rollers can be dried satisfactorily. Moreover it is possible to exchange a smeared set of rollers in short time for a clean one, so that the standstill of the machine is considerably shortened.

Further objects and advantages of the present invention will be apparent from the following description, reference being made in the accompanying drawings wherein a preferred embodiment of the present invention is clearly shown.

Figure 1 is a view seen from the outlet side, the rollers being cut in the plane of the pivots.

Figure 2 is a side view, partly in section;

Figure 3 is a side view of the bearing for the driving shaft; and

Figure 4 shows a roller with its two ends represented in longitudinal section.

The frame of the machine has been omitted since it does not bear on the subject matter of the present invention. There is provided a pair of upper rollers 1 extending generally horizontally and an identical pair of lower rollers 1a extending in the same general direction but immediately below the pair of upper rollers 1. The rollers are all of conical shape and it will be seen by reference to Figure 1 that the smaller ends of the lower rollers 1a are more closely aligned than the smaller ends of the upper rollers 1. The larger end portions of each of the rollers have end walls 2 aixed therein. Each wall 2 is centrally provided with an inwardly extending bushing 3. The bushings 3 are adapted to receive spherical ends or balls 4 of drive shafts 5 which are mounted in a Wall 6 of the machine. The balls 4 are each provided with dogs 7 which are engageable in slots 8 formed in the bushings 3.

Each driving shaft carries a gear 9; al1 the gears 2,737,909 Patented Mar. 13, 1956 ICC which engage with each other are driven by another gear 10. The gear 10 is rigidly mounted on the main shaft 11 which is rotated in a conventional manner by a motor or the like not shown in the drawing.

At the tapered end of each of the rollers, there is a bearing sleeve 12 or 12 penetrated by a small axial shaft or pin 13 or 13' which is connected to the rollers by means of bolts 14 or 14. The outer ends of the shafts or pins 13 or 13 indicated by 15 or 15 are uted to obtain rotation of the sugar rope which is leaving the machine.

By means of bolts 16 and 16a, bearings 12 and 12 are connected to pivot pins 17 and 17 which are slidably received in journal boxes 18 and 18a, respectively, whereby the bearings 12 and 12 are retained in a desired position. As may be seen at a glance, the pivot pin of each tapered end of each roller can be asily taken out of its journal box, and the roller then removed from its ball 4. It will be apparent that the journal boxes 18a are fixed in position while the boxes 13 are swingably mounted as will hereinafter appear. In this way it is possible for the rollers to be removed most simply from the machine and to be inserted again.

The set of rollers is in a conventional manner disposed within a housing 19 which is open at the top for receiving the charge of the sugar batch. The two upper rollers 1 may have the positions of their smaller end portions adjusted by swinging the journals boxes 18 about pivot members 20 mounted in conventional manner in the machine. Levers 21 are dependently connected to the journal boxes 18 and are connected in conventional manner at their lower ends to nuts 22 which are engaged with threaded portions of a spindle 23 provided at each of its ends with a hand wheel 24 and 25, respectively. Turning of either hand wheel acts to adjust the position of the upper rollers 1 with respect to each other and with respect to the lower rollers 1a.

The operation of the machine is as follows: A doughlike mass of sugar is placed in the machine upon the lower rollers la and between the upper rollers 1 and is given a conical shape by contact with such rollers. The sugar mass leaves the machine between the lluted ends 15 and 15 of the shafts or pins 13 and 13. By adjusting the positions of the smaller end portions of the upper rollers as above set forth, the diameter of the sugar mass as it leaves the machine may be regulated.

What I claim is:

In a machine of the character described, a pair of upper conically shaped rollers extending generally horizontally, a pair of lower rollers mounted immediately below and inwardly of said upper rollers, each of said rollers having an axial shaft extending from its smaller end, a bearing sleeve revolube upon said shaft, a pivot pin pivotally connected to each sleeve, a pair of swingable journal boxes, a pair of fixed journal boxes, and means for moving said swingable journal boxes, said lower rollers having their pivot pins slidably received in said fixed journal boxes, and said upper rollers having their pivot pins slidably received in said swingable journal boxes.
