ApplieaumJm -ze, 19-45,-Serial:No.--607319? The present invention relates to new and i useful improvementsinpQrtabIeeIectriC cleaner and scraping tools designed primarily for use in cleaning and scraping meat blocks as well as for cleaning, scraping, or dressing various other wood surfaces and the invention has for its primary object to provide an electrically driven rotary cleaning or scraping drum removably mounted transversely at the bottom of the tool for engaging the work as the tool is moved over the surface thereof.
A further object of the invention is to provide a tool of this character adapted for interchangeably mounting various types of cleaning, scraping and cleaning drums therein.
Another object of the invention is to provide a vertically adjustable bottom surface for the tool by means of which the rotary drum may be adjusted relative to the work.
A still further object is to provide an apparatus of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a side elevational .view with parts broken away and shown in sections.
Figure 2 is a front end elevational view.
Figure 3 is a vertical sectional view taken substantially on the line 33 of Figure 2.
Figure 4 is a bottom plan view.
Figure 5 is a side elevational view of one type of cleaning or scraping drum.
Figure 6 is a fragmentary longitudinal sectional view thereof, and
Figure '7 is a similar view of a modified cleaning drum construction.
Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the base of the tool having a gear housing 6 on the upper surface thereof and above which is supported an electric motor I mounted in a vertical position and including a shaft 8 extending downwardly into the gear housing 6 and having a worm 9 secured to its lower end engaging a worm gear I0 secured to a shaft ll journaled transversely in the housing 6.
The gear housing 6 is formed at its front end with a drum housing 12 having its bottom porroiaim (o1. lee-11 51) I tioneopeni as; indicated at; .l 3; and A in: the;.opposite; sides. of. which :a-transversely extending shaft; 01";
arbor I4 is journaled for attaching a drum l5 thereto by means of screws H3 inserted through flanges I! carried by the shaft I l and engaging the ends of the drum.
The drum l5 may be formed on its outer surface with longitudinally extending cutting teeth H3, or the surface of the drum may be provided with cleaning or scraping bristles i9 as illustrated in Figure 7 of the drawings. One edge of the drum i5 is exposed through the opening I3 at the bottom of the base 5 as indicated in Figure 3 of the drawings.
An adjustable bottom plate is secured to the under side of the base 5 rearwardly of the housing 12 by means of screws 21 and eXpansible coil springs 22 are interposed between the bottom plate 20 and the base 5 to yieldably project the bottom plate downwardly on the adjusting screws.
The lower front edge of the housing I2 is provided with an adjustable bottom plate 23 slidably mounted longitudinally on inclined dove-tailed guides 24 at the side edges of the housing I2 and slidably adjusted by means of a screw 25 journaled in the end of the plate 23 and threaded in a lug 26 carried by the lower portion of the housing l2 as illustrated in Figure 3 of the drawings. The adjusting screw 25 is secured in its adjusted position by means of a set screw 2'! threaded upwardly through the plate 23 and engaged in a groove 28 in the adjusting screw 25.
The inward and outward movement of the plate 23 by the adjusting screw 25 will raise or lower the front end of the device.
A handle 29 projects forwardly and upwardly from the housing l2 and a rear handle 30 extends upwardly from the rear end of the base 5 to the upper portion of the motor housing 1 and is provided in its upper portion with a switch 3! for controlling the operation of the motor.
The shaft It or the drum I5 is driven by the shaft I I by means of a chain 32 and sprockets 33 and 34 secured to the outer ends of the respective shafts and enclosed in a housing 35 at one side of the housings 6 and I2.
In the operation of the device, the bottom plates 20 and 23 are moved over the surface of the work in the manner of a plane with a portion of the drum l5 projecting downwardly through the opening [3 whereby to clean, scrape or otherwise treat the surface of the work in accordance with the type of drum being used.
In view of the foregoing description taken in conjunction with the accompanying drawings it is A scraper comprising a base, a front end drum sprocket and chain drive in the side housing operatively connecting said shaft to said drum, a motor housing surmounting the drum and gear housings, and a motor in said motor housing having a vertical armature shaft terminating in a worm and extending into the gear housing and operatively engaging said worm gear.
