jlliarjzgy Patented May 15, 1934 DEVICE FOR CLEANING THE HEARTHS F BAKING OVENS Wilhelm Sanger, Oassel, Germany Application July 8, 1932, Serial No. 621,406 In Germany October 14, 1930 1 Claim.
For cleaning the hearths of baking ovens there are already known devices comprising a roller.
brush fitted to a tubular handle and adapted to be set in rotation by means of bevel gearing I from a motor-driven shaft extending through the handle. The known constructions in which the roller brush assumes an invariable position relatively to the handle are subject to the drawback that, as only a small aperture is provided in the oven wall for insertion of the brush, the brush does not have access to every corner of the hearth. This is especially the case at the junction of the hearth floor and the side walls where refuse and dust tend mainly to collect.
In the device according to the invention the brush is mounted on the handle'so as to be capable of lateral movement, so that the brush can accommodate itself to every form of oven. It is thus possible to remove completely dust and dirt from the most inaccessible parts of the oven chamber. With this object a Cardan joint is interposed in the motor-driven shafting penetrating the handle and serving to drive the brush, and the brush carrier is mounted in a bifurcation presented by the handle so as to be capable of lateral movement under the control of springs.
In the accompanying drawing Fig. 1 is a plan and Fig. 2 a side elevation partly in section, of one embodiment of the invention.
As shown in the drawing, there is mounted on the free end of the tubular handle 1 a small driving motor 2 preferably constructed as an electric motor. The rotary motion of the driving motor 2 is transmitted by way of a shaft 3 located within the tubular handle and a Cardan joint 4 and bevel gears 5, 6 to the spindle 7 common to the two roller brushes 8, 9. The spindle 7 is so fitted to the handle 1 that it can be moved laterally in opposition to the action of tension springs 10, 11, it being understood that the Cardan joint 4 allows transmission of the rotation to the brushes 8, 9 irrespective of the position of the spindle '7.
The tension springs 10, 11 are connected at one end to holders 12, 13 secured to the handle 1 and at the other end to links 14, 15 connected with the spindle '7, so that, after being moved, the spindle is restored into its position perpendicular to the handle 1. Vertical movement of the brushes 8, 9 is prevented by the two cover plates 16, 17. The links 14 and 15 are connected with one another by traverses 18 and 19, the middle portions of which are designed as bearings, in which the portion 3 of the shaft 3 is supported which is the portion between the joint 4 and the bevel-wheel 5. The wheels 5 and 6 will, thus, remain in mesh with one another when the brushes and the links 14 and 15 oscillate 60 on the pivot 44.
To clean the oven, after the motor has been switched on, the brush is introduced into the oven by manipulation of the handle. Due to the circumstance that the brush is capable of oscillatory movement relatively to the handle,
the brush accommodates chamber.
itself to the form of the As the rotation of the brush is continuous and uninterrupted, refuse etc., is removed from all corners and angles of the chamber and delivered through the openingby way of which the brush is introduced.
Instead of being mounted at the end of the handle, the motor may the brushes, in which latter case the motor will i be interposed between be coaxial with the brushes.
I claim:
A portable cleaning apparatus for baking said tube, a U-shaped frame, in the body of which the said axle is supported and the legs of which extend in the direction to said tube, a transverse member affixed to the tube near the ends of the legs of said U-shaped frame, helical tensile springs connecting said leg ends with the ends of said transverse member, a Cardan joint inserted into the said shaft between the legs of the U-shaped frame and dividing the shaft into two coaxial parts, the said tube terminating in front of said joint, and plates extending forth a pair of parallel guide from said transverse member to the body portion of the U-shaped frame and holding the said joint and the adjacent portions of the said shaft and the said tube enclosed between them.
WILHELM SANGER.
