To all whom it may concern:

Be it known that I, THOMAS OWEN DA. ES, a subject of the King of England, residing at Live 001, inthe county of Lancaster, England, ave invented new and useful Improvements in Machinery for Makin Cup-Wafers, Sugar-Wafer Biscuits, and the ike, of which the following is a specification.

This invention has reference to machinery for making cup wafers of various shapes, sugar wafer biscuits, and the like; and it relates more particularly to that type in which a plurality of sets of cooking lates are mounted on a revolving part, and move in sequence round about an axis, being heated during their revolution, on both sides, so

that the cooking and manipulation of the wholemachine requires the attention of only one person, and the whole of the operations are erformed in sequence in the one machine.

T e invention has primarily for its object and effect, to provide a machine of inexpensive and simple construction of the type referred to, and one in which the cookin and its manipulations, canbe carried out wit ease and re larity, and the articles produced are of goo quality, and made rapidly, and with little wastage or breakages.

In the drawings hereto annexed, the machine constructed according to this invention, that is, involvin the improvements is illustrated, and it w' 1 be described by the aid of these drawings; the novel characteristics of the machine being set out in the claiming clauses concluding the specification.

In the drawings, Figure 1 is an end elevation Fig. 2 is a side elevation in section; and Fig. 3 is a plan.

The machine according to this invention has two outside frames, namely, a front frame 1, and a back frame 3; and within these frames there is a rotar frame 5 for carrying and revolving the p ates in which the cups, biscuits, or other articles are made; this rotary frame 5 consisting mainly-of two parallel plates connected together and mounted on hollow trunnions 7 and 8, fitting and working in bearings 2, 4, of any suitable kind in the front and back frame plates 1, 3.

Extending through the center of these Erunnionp? theiil'e isa hollow 51121551? or tube 8 or su eatin or coo as to a burner g, iflii ch is dis osed within a d under the lower or innerp ates of the apparatus when they reach the'top position.

The parts in which the batter is introduced and cooked consist of a lower plate 11, in which the matrices 12 for holding the material are carried, and an upper plate or cover 13; these plates being of any known suitable form. And between these plates there may be a movable plate for stripping or starting the cups, biscuits, or the like, off the die cores when the upper plate or cover 13 is opened, after they have been cooked.

The rotating frames 5 are made of polygonal form, that shown in the drawing bein hexagonal, with six sets of plates 1 1, 13, cfitte to and employed in connection with them.

The lower or inner plates 11 are fixed on the edges of the frames 5, and the outer plates or covers 13 are hinged by ahinge 15, to these lower plates; and at the'front, on the front frame 1 a projection (16, 19,) is provided which operates in connection with arts hereafter described, by means of w iich, when the rotary carrier frames 5 are revolved,

say 55 of a revolution, and one of the cover or upper plates 13 is coming towards the top position, it is unlocked, and that plate or cover which is just passing down from the top positionis locked, and remains held and locked till it arrives at the opposite side.

The projecting part referred to is in two portions or sections, 16, 19, one 19, at the upper part, which effects the unlocking action, having an upwardly extending flange 17, which is inclined on its inner surface see Fig. 2-so as to engage with the inner end of the catch, 20, which looks the two plates 11, 13, together, and pull it away from them, as hereafter described; while the other portion 16 extends practically-all round in an even vertical plane, except at the leading and leaving edges, which are inclined or tapered inwards, and which, by one of these inclined parts, forces the said catch into engagement with the lower plate, moving it in the opposite direction to that just described, and holding it in this position until it comes round again to the unlocking position, which is near the top where this part 16 ceases, and the part 19 is placed. This unlocking action takes place as the plates come up to the top position, and the ocking action takes place as they move away from this position, after the plates or matrices are re-charged with fresh batter. There are gaps at 18 between the unlocking and locking portions 16, '19, of these projecting parts, to allow of the swinging to and fro of the plate catches 2O referred to. With regard to the catches 20, each is hinged to the end of the u per plate 13, a catch of course being used in connection with each couple of plates.

The catch is weighted by weights 21, which normally tends to press it out of engagement with the lower plate 11, and holds it in the desired position when the plate 13 is brought down to engage with the plate 11 that is, it prevents this catch from fouling the late 11 when so brought down. It is the ower end of this catch 20, with which the flange 17 of theupper projecting part 19, and also the other part- 16 operates, as above described. I

With regard to the opening and closing action of the plates 13, when one of these comes to the up er position, and the matrices 12 are to fi e emptied of the cooked articles, and recharged with fresh batter, the upper plate or cover 13 carrying the dies or cores is unlocked, and it is raised, being assisted by counter balance wei hts 22, and is held there by the weights uring these operations. These weights 22 in one arrangementthat as shown in the drawings are' mounted on spindles 23 supported in bearings 24, fixed on the back stationary frame late 3, and coincident with the axis of the l iinge 15 of the upper plate or door 13; and they are adapted to be connected up with and act on the then upper plate 13 by upper levers 25, fixed at their back ends to the spindles 23, and carrying at their front end-which are connected together by a bar 26 on an engaging part 27, with which the pro'ecting part 14 on the end of each upper plate 13 is adapted to engage or move, as a pair of plates come to the top position.

In action, as a pair of plates are brought by the revolving gear round towards the upper and horizontal position, the engaging part 27 will be held down, by one of the curved projecting parts 6 on the face of the front revolving frame 5, which will then lie over the inwardly projecting part 28 of the device 26. Then, when the complete upper position is reached by the plates, the part 28 will be clear of this projection 6 that is, it will be adjacent to a ga between two of these rojections 6-whic projections and gaps alternate all round the frame 5so that the en ager 26 can move up or down.

In t is position, the catch 20 will have been disengaged from the lower plate 11, so that the plate 13 is freed; and then this upper plate 13 is raised at the front by the handle 29 of the engager 26, it being assisted by the counter-balance weights 22. When so raised about the hinge, the cooked articles can be removed, and fresh batter introduced into the matrices, whereupon the u per plate 13 is again brought down by 11 1mg down the handle 29, which brings t e engager 26 into the position shown in Fig. 2;

and the frames 5 are then again revolved, when the catch 20 is immediately pressed by the inclined end of the projection 16 under or into engagement with the lower plate 1 1, and held there by it, and so the plate is locked. And then immediately after the projecting parts 1430f the upper door 13 leave-the groove 27 in the engager 26, another of the projecting parts 6 immediately comes over the inward flange 28 of the enga er 26 and holds it, so that it cannot of itse f fly up; whereupon another of the engaging parts 14 of the next set of plates moves into the groove 27 of the engager 26 which has just been vacated by the projection 14 of the preceding set of plates.

The carrier frames or disks 5, with the plates, are revolved by a suitable crank 30 in the front, which operates a pinion 31, which gears with a spur wheel 35 on one of the trunnions 7 of the rotary frame the pinion 31 and spur wheel 35 being of such a size that one revolution of the former and handle, will revolve the apparatus of a revolution in the case of the 'six sets of plates being employed. And the crank 30 is provided with a catch 32 on the end of its pivoted handle 33, which engages with a notched inclined plate 36 on the frame, the catch 32 being normally pressed towards the late 36 by a spring-pressed bolt 34. To disengage the catch. 32 from the notch in the plate 36, the handle 33 is pressed inwards, and upon releasing this pressure, at the end of a revolution, the catch reengages.

Two horns 37 are provided on the back frame 3, which, when the top plate 13 is open, prevent the a paratus being revolved, as they come on eac side of'the hinged portion at 15 of the plate, and so should the catch 32 not be engaged with 36, the apparatus cannot be revolved.

At the bottom of the machine there is a second burner or heater 10, which heats the top plates or covers 13 of the different sets, when this plate is below, so that the cooking is effected on both sides.

What is claimed is 1. In machinery for making cu wafers, sugar wafer biscuits, and the like, 0 the type in which a plurality of sets of cooking plates are revolved or reciprocated about an axis, and are opened and closed successively, an inner stationary plate, and an outer hin ed plate having a stationary hinge connection with the inner plate, and having a detent at.
