PATENT OFFICE.
JOHN H. WEINBRENNER, OF NEW YORK, N. Y.
ELECTRIC SGRAPER.
Application filed April 29, 1924. Serial 1T0. 709,930.
To all whom it'ma z conceam:
Be it known that I, JOHN H. WEINBREN- NER, a citizen of the United States, residing at New York, in the county of New-York and State of New York, have invented certain new and useful Improvements in Electric Scrapers, of which the following is a specification.
This invention relates to electrically operated rotary scraping machines and more particularly to a novel and improved butcher block scraper, particularly adapted for cleaning very hard. uneven surfaces.
One of the objects of my invention is to provide an electrically driven, rotary scraping element having steel brushes which may be guided by hand across the surface of the block so as to clean and scrape the wood and remove any foreign matter.
To enable others skilled in the art to fully comprehend the underlying features ofmy invention that they may embody the same in the various modifications in structure and relation contemplated, drawings depicting a preferred form have been annexed as a part of this disclosure and in such drawings,
similar reference characters denote corresponding parts throughout all the views, of
which,
Figure 1 is a sectional view through the scraper showing the relation of the rotary scraping element to the motor casing. Figure 2 is a top plan. Figure 3 is a bottom plan.
Referring now to the drawings wherein likereference characters designate corresponding parts throughout the several views, 5 designates a motor casing and 6, the conductor connected thereto for driving the motor. A substantially wide band 7 is attached to the motor casing and connected thereto I have provided a handle 8 preferably secured by fastening elements 9 where- 'by the scraper may be guided across the wood block before the motor is started. It i will be seen that a slight pressure on the handle will tend to compress the spring.
whereupon the element 18 will ride upwardly in the extension of the plate 12 so that the pointsof the bristles will engage the block. An outer guard and casing 20 having an upturned, annular edge 21 encloses the brush head, plate and the bristles and also is sufficiently spaced from said bristles so that the dirt and scraping is prevented from being scattered as the brush isheing revolved at a high rate of speed.
The electrically driven scraper of course is of sufi'icient weight to bear against the block upon a slight pressure of the handle and since the steel bristles revolve at a high rate of speed, the surface will be cleaned and the foreign matter removed from the block being scraped. But very little effort, of course, is necessary to guide the electrically driven scraper across the surface of the block and the work can be expeditiously and easily accomplished in a very short time at a great saving of labor.
While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts as do not depart from the spirit of the invention or the scope of the appended claim.
Having thus described my invention. what I claim as new and desire to secure by United States Letters Patent is An electric scraping machine comprising a casing, a motor, a vertical shaft driven by the motor, an annular plate connected to the shaft and having a hollow extension formed with an internal annular flange, a brush head and brush attached to the plate, a cylindrical element having a top flange supported by the hollow extension, and a In testimony whereof I aflix my signature tension sprin within said cylindrical elein presence of two witnesses. ment, one en of the said spring bearing against the shaft and adapted to normally JOHN WEINBRENNER -1 5 maintain the lower end of the cylindrical Witnesses:
