JOSEPH S. PEBELMAN, OF NORWOOD, RHODE ISLAND.
ROOF-SCRAPING MACHINE.
. ployed to any other purpose for which it may be adapted, and the object/of the ina ,ventlon is to provide a carriage on which s mounted a scraping roll arranged to engage the surface and remove the top material therefrom and deposit the same into a guard chute, to be conducted toa point to one side of the path of travel of the carriage.
A further object of the invention is to provide a multiplicity of yieldable scraping fingers on the roll and also to provide means whereby the roll itself with its scrapers, may be adjusted vertically in the carriage.
\Vith these and other objects in view, the invention consists of certain novel features of construction, as will be morev fully de scribed, andparticularly pointed out iuthe appended claims.
In the accompanying drawings.
Figure 1. is a side elevation of my improved scraping machine.
Figure 2 is a plan view ofthe machine with the driving motor removed; and show ing the guard chute in section on line 2--2 of Figure 1.
Figure 3 is a detail illustrating the lower connection of the adjusting screw by which the scraping roll may receive its vertical.
adjustment in the carriage.
Figure 4.- is a reduced view showing an elevation of the guard chute, looking from the inner side outward.
With reference to the drawings, 10 designates the two side frames of the machine, which are preferably formed of channel bars, the forward ends of which are supported by wheels 11 mounted upon the shaft 12 which extends through bearings 13 attached to the under side of the frame bars 10.
The rear portion of this frame is supported upon the single wheel 14 which is mounted upon the shaft 15, the ends of which are bolted as at 16 t0 the free ends Specificationof Letters Patent.

1921. Serial No. 472,219.
' of the adjustable frame arms 17. The inner ends of these arms are pivotally secured by bolts 18 to the channel bars 10. An adjustable screw 19 is threaded through the bracket 20 supported on the cross bar 21 and extends downwardly, its lower end. 22 passing through an opening in the bar 23 on the adjustable arms 17 whereby the rotation of this screw serves to adjust the elevation of the scraping roll, presently described.
On the forward end of these channel bars which form the frame of the machine I pivotally mount a pair of bearing arms 24!: on. the pivot bolts 25, and theouter ends ofthese arms provide bearings for the roll shaft 26 on which shaft is mounted the scraper roll 27.
The opposite ends of these arms 2% are supported on the adjusting screws v28 whereby the roll member receives a relative vertical adjustment in the carriage by simply rotating these screws.
This scraping roll extends transversely of the machine and is provided with a plurality of rows of spaced-apart fingers 29 which are set to extend tangentially from the surface of said roll, said fingers being constructed. preferably of thin strips of metal with their outer ends 80 bent or turned slightly outwardly so as to produce a drawing or scraping effect upon the surface engaged as the carriage advances.
I preferably bind or secure each row of these strips, blades or fingers to the roll by means of bar 31 through which screws 32 are passed and threaded into the surface of the roll between the said scraping fingers whereby these fingers may be adjusted endwise so as to bring their ends into alinem cut with the others in the same row and also into operative relation with those in the other rows. By this adjustment the operating length of the fingers or blades may be regulated so as to control, in a measure, the resiliency of the scrapers. In other words the longer the scraping finger the more yieldable it is and when the length of the scraper is reduced it becomes stiffer in its scraping action. I
The scraping fingers in the different rows are arranged in staggered relation so as to completely cover the surface on which the roll is operated.
On. one end of this roll I have mounted a sprocket wheel 33, and I have also shown a motor 34, preferably of the internal combust-ion type, as having the shaft 35 on which I have mounted another sprocket wheel 36 by which this roll may be driven through the sprocket chain 37, but any other desired type of driving motor may be employed.
In order to provide simple and effective means for controlling the discharge action of the material raised by the rapidly rotated scraper roll, I have provided a guard member 38 which is preferably formed of metal and in the shape to extend over, around and partially inclose the extremities of the scraping fingers on the roll, which guard is supported from the frame by the upper and lower arms 39 and 4:0.
This guard is provided with. an inclined trough-shaped portion 41 into which the material is thrown by action of the scraping roll, the jarring or shaking motion. of the motor causing the material to feed along in the inclined portion and to be finally discharged from the end 42 thereof to one side and out of.the path of travel of the carriage. I have also provided a bearing portion 43 which serves as a guide for conducting the material up over the edge 44: into the inclined trough portion of the guard.
At the rear of the frame I have attached an operating handle 45 which is mounted on the upper ends of the side arms 46 by Which the machine may be manipulated over the surface to be treated.
The device is extremely practical in CO11- struction and effective in its operation for removing gravel or material from a roof, but it may be employed for any purpose for which it is adapted.
The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I re serve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by, the terms of the appended claims. y
1. A portable scraping machine comprising a carriage, a scraping roll operatively mounted thereon and having a multiplicity of flexible scraping fingers each having its Working edges turned at an angle to the plane of its body portion for yieldably engaging the surface to be operated upon wlth a scooping action, and a motor on said scraper for driving said roll.
2. A portable scraping machine comprising a carriage, a scraping roll operatively mounted thereon and having a plurality of rows of spaced apart flexible scraping fingers each having an ontwardly-turned working edge for yieldably engaging the surface to be operated upon with a scooping action, and a motor on said carriage for driving said roll.
3. A portable scraping machine comprising a carriage, a scraping roll operatively mounted thereon and having a plurality of rows of spaced apart flexible scraping fingers set tangentially to the roll and in staggered relation so as to cover the m1 plete surface on which the roll is operating.
4;. A portable scraping machine comprising a carriage, a scraping roll operatively mounted thereon and having a multiplicity of flexible scraping fingers for yieldably en gaging the surface to be operated upon, said fingers being set tangentially on said roll, and means for driving said roll.
5. A portable scraping machine comprising a carriage, a scraping roll operatively mounted thereon, and having a multiplicity of flexible scraping fingers each having its working edges turned at an angle to the plane of its body portion for yieldably engaging the surface to be operated upon with a scooping action, a waste-receiving guard. chute carried by the machine and into which the removed material is deposited by said scrapers, said chute being set on an incline whereby the material deposited therein will be conducted to a point outside the path of travel of the carriage.
6. A portable scraping machine comprising a carriage. a scraping roll operatively mounted in said carriage, yieldable scraping means carried on said roll, means for adjusting the elevation of said roll in said carriage, and means whereby said scrapers may be adjusted to regulate their flexibility.
7. A portable scraping machine comprising a carriage, a scraping roll operatively mounted in said carriage and having a multiplicity of flexible scraping fingers for yieldably engaging the surface to be 0perated upon, and means whereby said scrapers may receive an. endwise relatively adjustment on said roll.
In testimony whereof I afiix my signature.
