- 3 Claims.
merits being preferably power operated while the control or movement of the device from place to place on the floor is preferably manual.
The invention has for one of its objects the provision of a construction which is equally well adapted for dressing or resurfacing the floors adjacent the side walls, thus enabling an entire car floor to be dressed or resurfaced by my improved device, with the result that a great saving-in time and labor is accomplished The objects and advantages of my invention will be readily comprehended from the following detailed description of the accompanying drawings, wherein:
Figure 1 is a plan view of my improved device; with portions of the cutter guard and of the hand wheel broken away and in section.
Figure 2 is a side elevation of the device.
Figure 3 is a transverse sectional view taken substantially along the line 3-3 of Figure 1.
Figure 4 is a vertical sectional view taken along the line 4-4 of Figure 2, looking in the direction of the arrows.
Figure 5 is a sectional view of a portion of the main frame and arbor, the latter having another form of cutter.
In the particular exemplification of my tion, the device is shown operated by means of a suitable electric motor generally indicated at l0, with one end of the armature shaft provided with a suitable pulley wheel H for receiving the driving element or belt I2.
The motor is properly mounted on and secured to the main frame [3, which is preferably composed of suitable metallic members integrally or otherwise secured together. The sides of the frame at the forward end also involves the side plates I4, l5 intended to aiford support and bearing for a rotatably mounted arbor I6, see Figure 3. The arbor I6 is supported by bearing blocks l1, l8, secured to the lower'side of the plate l4 and the portion l3 of the main frame; the outer end of arbor I6 is also supported by bearing plate l9 which is preferably removably secured in place to the outer end of the semi-cylindrical side plate and guard l5, see Figure 1.
One end of arbor I6 is provided with a pulley which receives the driving belt l2, which is held in place on pulley 20 by means of a suitable retainer or collar 2 I, which in turn is held on the end of the arbor by a suitable nut as at 22.
inven- I The other end of the arbor l 6 is shown provided with a cutter cylinder 23, which is shown provided with a plurality of cutter blades 24 extending the length of the cylinder 23 and arranged at a suitable angle--say for example 5 twenty-five degrees relative to the longitudinal axis of the cylinder 23 so that the ends of the respective'blades will overlap or be disposed in the same horizontal plane longitudinally of the cutter cylinder 23, as can be clearly seen in Figure 1.
The cutter cylinder 23 is properly mounted on i the arbor It by means of .a collar 25 and washer and nut 25 at the opposite side; the washer and nut 26 being located within or beneath the bearing plate l9 whose ends are secured to the guard 5 element IS.
The main frame at the rear end ofthe device has an extension as at 21, provided with an opening in which a bushing 28 is inserted; the bushing being shown held in place by nut 29. The bushing '28 is internally threaded and has the screw 30. The screw-30, at its upper end, is provided with a hand wheel wrench 3! whereby the screw 30 is made to screw up or down in the bushing 28.
The screw 30 is shown bored to receive the spindle 32 of a fork 33 through which an axle 34 is rotatably passed.
The axle is provided with wheels 35, 35, secured to the axleby means of nuts 36, 36; the wheels 30 35," being held in proper positions relative to the fork 33 by spacing collars 31, 38. l The spindle 32 of the wheel carrying fork is rotatably held in the bore of screw 30 in any suitable manner, as for example by the set-screw 39 which engages 5 in the annular groove in the spindle. I
In order to hold the caster wheel fork rigid,
I show the brace bars 40, whose rear ends are bolted or otherwise secured to the fork 33; while the forward ends are slottedas at. in Figure 2 40 to receive the cap screws as at 42, providing a semi-rigid connection which will permit vertical movement of the fork 33 when the hand wheel wrench 3| is rotated. It is apparent that by rotating the wrench 3|, it either raises or lowers the caster wheel carrying fork and hence raises or lowers the rear end of the device and hence lowers or raises the forward cutter-arbor carrying portion of the device, thereby adjusting the cutters to the proper height or relation to the floor to be resurfaced.
The device is also provided with a pair of supporting wheels 43, which are located slightly rearward'of the cutter arbor; and the device will tilt about these wheels when the caster wheels are raised or lowered through rotation of the screw 30 in the internally threaded bushing 28.
In order to permit easy rotation of the screw 30 (which rotates without imparting rotative movement to the fork 33), I prefer to provide anti-friction bearings between the lower end of the screw 30 of the fork, as shown at 44 in Figure 4.
The rear end of the device is provided with a handle as at 45, which may consist of a continuous bar or rod as shown, with the ends suitably secured on opposite sides of the main frame, as shown in Figure 2, by means of bolts 46. With this handle the device may be made to travel along the floor.
The device may be provided with a suitable control for regulating and controlling operation and speed of the motor; and suitable terminals are also provided for receiving the current conducting wire which leads from a source of supply and which, of course, is of length sufficient to permit the device to be moved over a'suitable floor area.
It is apparent that as current is supplied to the motor, the cutter arbor [6 will be rotated by means of the driving connection between the motor and the arbor, as,for example, the drive belt l2. As the arbor i6 is rotated, the cutter 23 with its blades 24 will resurface'or redress the wood floor; the degree of cutting or dressing depending upon the degree to which the caster wheels 35, 35 have been lowered. through operation of hand wheel wrench 3 I.
The cutter blade carrying, cylinder 23 is employed when the resurfacing of the car floor is to be done some distance away from the side walls. I
When house car floors adjacent the side walls are to be resurfaced, the guard wall I5 with the bearing l9, as well as the cutter 23 are removed;
this being readily accomplished by removing the bolts 47 which hold the guard 15 in place against the main frame; this allows the bearing l9 to be slipped off the end of the arbor E5. The nut 26 is then removed from the arbor, allowing the cutter 23 to he slid off the free end of the arbor.
The arbor I6 is then provided with a spacing sleeve 48, as shown in Figure 5, and with another,
As this cutter is intended to resurface floors adjacent. to the walls, it is apparent that the arbor l6 cannot protrude or extend beyond the side of ficient to position the end of the arbor and thenut within the counterbore SI of the cutter as shown.
It is apparent that the cutters are readily interchangeable thus adapting my improved device to the resurfacing of the entire floor, as the cutting blades 50 of cutter 49 will be operative immediately adjacent the side walls and in the corners of a car floor or the floor of any other structure.
While the construction shown in the drawings is believed a simple'embodiment of the invention, modifications are possible and may be made without departing from the invention as defined by the claims.
What I claim is:
l. A floor resurfacing device comprising a main frame provided with supporting wheels; an arbor revolubly mounted at the forward end of the frame and disposed transversely beyond both sides of the frame; interchangeable blade carrying members adapted to be removably secured on one of the extended ends of the arbor beyond the side of the frame. and to rotate therewith; a guard member removably secured to the side of the frame and adapted, when certain of said blade carrying members is used, to support the free end of the arbor and to expose said end of the arbor when the guard is removed; a sleeve slidable on the arbor when the guard member is removed whereby a blade carrying member is held at the outer end of the arbor; an electric motor mounted on the frame and having operative relation with the arbor so as to rotate the latter; a caster wheel carrying fork provided with an upstanding spindle, a bored screw adapted to rotatably receive the spindle, an internally threaded bushing for receiving said screw to permit the latter to screw upwardly or downwardly and thereby vertically adjust'the rear part of the frame; means whereby said bushing is removably secured to the frame, and means whereby the device may be guided.
