Application fled June 8, 1927. Serial No. 196,354.

' This invention relates to mixing machines of the type used by bakers for stirring the ingredients of cake or bread dough, and for beating e gs and the like, and more partrcularly to the type of mixing machine having detachable mixing bowls that are carried by the machines in proximity to the beater elements.

An object of the invention is to provide means for raising the mixing bowls into operative position with the heaters of a mixlng machine, and for lowering the bowls at the conclusion of the beating operation.

Another object is to produce an eflicient, strong and durable apparatus which may be economically constructed and operated.

Other objects and advantages will heremafter appear.

The views of the drawings are Figure 1 is a side elevation of a machine showing the application of my invention. thereto, the outline of the machine being illustrated by broken lines;

Fig. 2 is a plan of the structure shown in Fig. 1; and

Fig. 3 is a rear elevation.

Referring to the drawings, the mixing machine 5 is provided with a pair of spaced vertical standards 6.

A saddle 7, having a pair of perforated bosses 8 slidably mounted on the standard 6, is adapted to support a bowl 9, and raise the same into operative position with a vertically disposed beater 10 carried by the machine.

The bo W1 9 is provided with a flanged ring 11 adapted to be carried by a air of arcuate arms 12 with which the saddle is provided. The extremities of the arms 12 have upwardly projecting 13 which are inserted in openings 14 in ring 11.

The bowl,'when not in the saddle 7, is carried on a truck 15 so as to be easily transported. This truck consists of a ring-shaped ody which receives the bottom of the bowl. The bottom of the truck has a plurality of anti-friction balls 16.

In this way, the bowl can be rolled into a position with respect to the saddle. The saddle is in a lowered ESltiOll, such as that illustrated in Fig. 1. e bowl 9 is then tilted in the manner illustrated, so that a rear edge portion 11" thereof is positioned under a shoulder 12' formed on the saddle 7. v The subsequent rai of the saddle 7 by means hereinafter deifiilied results in a movement should the electric pinion 33 which transmits the of the pins 13 into the openings 14 of the ring 11 and the engagement of the ring 11 with the arms of the saddle 7. The bowl 9 is now in a horizontal position and supported by the saddle 7.

Means for raising the saddle include a ver- 1 tical screw 17 upon which is mounted a boss 18 projecting rearwardly from the saddle 7 and integrally formed therewith.

The top of the screw has fixed thereon a gear 19 and a bevel gear 20. The latter gear meshes with a bevel gear 21 on a horizontally disposed shaft 22, while the gear 19 meshes with a gear 23 fixed to a vertically disposed shaft 24.

The shaft 22 carries a gear 25 meshing with a gear 26 on a shaft 27. The shaft 27 is horizontally disposed and overlies the shaft 22. F urthermore, the shaft 27 extends trans versely of the machine and has a hand wheel 28 fixed on one end. The purpose of the hand wheel 28 is to permit the screw 17 to be manually rotated.

The shaft 24 has abevel gear 29 fixed on its lower end. This gear meshes with a similarly formed gear 30 on a short horizontally disposed shaft 31.

Rearwardly of the gear 30, the shaft 31 carries a gear 32, which is in meshwith a pinion 33 of a reversible electric motor 34.

Beneath the gear 23, the shaft 24 is provided with a clutch 35. This clutch may be disengaged by any suitable means (not shown) so that the gearing drivenby the motor can be disconnected from the screw 17 when the hand wheel 28 is-used, as be readily understood.

In actual practice the motor 34 is used for the purpose of raising and lowering the saddle through the system of gears described,

while the hand wheel 28 and the gearing actuated thereby is desirable for emergency use power in any way be turned off.

Power from the motor 34 will rotate the power to gear 32. The gear 30 will then transmit the power through gear 29 to shaft 24. The power is then transmitted, at greatly reduced speed, to the screw 17 through the gears 23 and 19, and the bowl will be raised to the position illustrated by the broken lines, Fig. 1.

When it is desired to lower the bowl from its position with respect to the beater 10, the motor 34 is reversed so that the gearing and screw 17 will be rotated inthe opposite rection.

The invention set forth herein is, of course,

susceptible of various modifications and l adaptations.

The invention claimed is 1. In a mixing machine, the combination with a saddle having a projecting shoulder, of a bowl having an annular flange therearound, said bowl being adapted to be tilted while on a floor surface, so that a portion of said flange extends under said shoulder of.

the saddle, and means for raising said saddle,

permitting said bowl to move from said tilted position to a second position wherein it is supported on said sadd e.

2'. In a mieig machine, the-combination move from said tilted position to a second position wherein it is supported on said saddle, the lugs thereof engaging the openings 111 said flange.
