PORTABLE SURFACE-CLEANING TOOL.
Application filed June 4,
This invention relates to power driven devices for cleaning surfaces in general and more particularly r removing scale or the like from said surfaces.
In the past the usual method for removing paint or scale has been through the use of a scraper or chisel. Chisels have been used in connection with air hammers for facilitating the work. The use of scrapers has always been a tedious procedure and the use -of chisels is no less tedious unless an air'.
hammer is used in which case serious damage is likely to result to the surface being cleaned.
In order to facilitate the cleaning of surfaces in general and more particularly the removal of scale and the like. therefrom, I provide a handy device of the above type havin a power unit mounted thereon togjth'er with a conveniently placed rotor iven by said unit and having a plurality of abrasive elements distributed about the periphery of said rotor and. adapted to contact wlth the surface being cleaned or sealed. In order to .carry out my invention, I employ a device consisting of a motor housing having a suitable motor therein, a handle at one end of said-housing, a tapered head at the other end of said housing, and a rotor mounted on a transverse spindle at the end of said head and operatively connected to said motor. The rotor includes a plurality ofangularly spaced axial pins arranged adjacent the periphery of said rotor and havcutters.
ing mounted thereon a plurality of annular The cutters are loosely mounted on the aforementioned pins and are adapted,
upon rotation of the rotor, to be projected due to centrifugal force into'contact with the surface to be cleaned. A suitable guard 1s mountedat the forward end of the head above the rotor to prevent flying scale or the like from injuring the operator. The entire device is of light construction and is adapted to develop a large amount of power. The general construction of the device is such .that 'it may be conveniently operated and manipulated by moving the rotor toward and away from the operator through means of the handle.
.Other important features will be apparent from the specification when taken in connection with the accompanying drawing wherein Figure 1 is a longitudinal elevational view showing a device embodying the invention; Fig. 2 is a cross sectional view taken at 1926. Serial No. 113,832.
described in connection with my co-pending application for U. S. Letters Patent, Serial No. 111,737, filed May 26, 1926. The housing 1 contains an electric motor and is provided with a suitable handle 2 both as described in the said co-pending application. A removable neck 3 extends from the forward end of the housing 1 and issubstantially the same as that shown in my co-pending application with the following exceptions:
The neck 3 is provided with an enlarged head 1 at the forward end thereof. The lower portion of the head 4 is preferably circular in profile. The driving shaft 5 which is mounted longitudinally in the neck 3 and is operatively connected to the motor, in the housing 1 extends forwardly into the .upper portion of the head 4;. The head 4 is provided with an enlarged recess 6 just above its center and near the end of the shaft 5. A threaded aperture 7 is provided in the end of the head 4 concentric with the shaft 5. A removable plug 7 is threaded in the aperture 7. A skew gear 8 is splined on the shaft 5 in the recess 6. The forward end of the shaft 5 may be, if desired, journaled in the plug 7. The head 4 is also machined to provide a central transverse bearing 9 fora spindle 10. The head is also recessed to contain a skew gear 11 mounted intermediately on the spindle 10 and in mesh with the skew gear 8. The side of the head 4 opposite to the bearing 9 is apertured to receive a removable disc 12,'said disc being apertured to provide a'second bearing 13 for the spindle 10. I
The lower periphery of the head 4.- is rovided with an arcuate foot 14 on whic is removably secured through means of screws 15, an arc'uate shoe 16 the purpose of which will be apparent.
The spindle 10 extends outwardly on either side of the head 4. Mounted on each outwardly extending portion of the spindleon eitherside of the head 4 is a plurality of discs 17. The discs 17 are connected together by a plurality of angularly spaced pins 18 arranged adjacent the peripheries of members 19 will, by centrifugal force, be
projected outwardly. The members 19 have their outer .peripheries provided with a plurality of integral jagged teeth 20 so that when they are projected intocontact with scale, paint, or the like on the surface desired to be cleaned or scaled, they will act to break such scale or the like. The discs 17 are, of course, splined on the spindle 10 and are prevented from falling off the end of said spindle by cotter pins 21 or other suitable means.
A suitable shoulder 22 is provided integral with'the upper portion of the head 4 and is adapted through means of screws 23 to support a semi-cylindrical guard 24 above the rotor and concentric therewith.
Different sized shoes may be used on the foot 14 depending upon the depth of cut or the thickness of scale desired to be removed.
It will be obvious to those skilled in the art that by reason of the provision of the rotor and the cutting elements thereon, the speed at which said rotor .may be driven, and the ease with which the device may be manipulated through the handle 2 and the general construction of said device, that surfaces of almost any thickness of scale may be quickly and convenienly cleared of such scale by the use of said device.
I am aware that many changes may be made and many details of construction varied throughout a wide range without departing from the principles of this invention and I do not propose being limited to the details shown or described.
I claim 1. A device of the class described comprising a motor housing, a handle therefor,
an armature in said housing, a spindle mounted on said connected to said armature, a lurality of discs mounted on said s indle or rotation therewith, a lurality o 'angularly spaced axially exten ing pins connecting said discs together and arranged adjacent the peripheries thereof, and a plurality of annular cutting elements mounted between said discs on said pins, said elements being provided with integral teeth on the outer peripheries thereof, the internal diameters of said elements being considerably greater than the diameter of said ins.
2. A device 0 the class described comprising a motor housing, a handle at one end thereof, a head at the other end thereof, an armature in said housing, a rotor mounted on said head transversely thereof and operatively connected to said armature, a plurality of movable cutting elements on said rotor ada ted to be moved relative thereto by centri ugal force when said rotor is operated, and an arcuate foot on said head adjacent the lower periphery of said rotor.
3. A device of the class described comprising a motor housing, a handle at one end thereof, a head at the other end thereof, an armature in said housing, a rotor mounted on said head transversely thereof and,operatively connected to said armature, a plurality of movable cutting elements on said rotor adapted to be moved relative thereto by centrifugal force when said rotor is operated, an arcuate foot on said head adjacent the lower periphery of said rotor, and a removable shoe on said foot.
4. In a. device of the character described, a rotor including a plurality of coaxially disposed discs, pins secured through said discs and spaced apart circumferentially of housing and operatively the rotor, and annular cutters disposed
