JOSEPH O. PELTIER, OF WINDSOR, ONTARIO, CANADA.

FLOOR-SCBAPER.

Specification of Letters Patent. Application filed March 5, 1908.

Patented April is, 1909. Serial No. 419,815.

T 0 all whom it may concern:

Be it known that I, JOSEPH C. PELTIER, a citizen of Canada, residing at lVindsor, in the county of Essex and Province of Ontario, Canada, have invented certain new and useful Improvements in Floor-Scrapers, of which the following is a specification.

This invention relates to improvements in scrapers for smoothing the surface of floors e like, and more particularly to devices of this character which are adapted to be operated by hand.

An object of the invention is to provide a device so constructed that the operator may increase its cutting or scraping eflect by a downward pressure, thus obviating the necessity for heavily weighting the device, and permitting of a compact, light and cheap construction.

A further object is to so construct the machine that it may be tilted or rocked laterally during operation to bring any part of the curved cutting edge of the blade into contact with the work; and further to provide certain other new and useful features, all as more fully hereinafter described, reference being1 had to the accompanying drawing, in w 10 Figure 1, is a perspective view of a device embodying t e invention; Fig. 2, is an enlarged end elevation of the same with one wheel removed; and Fig. 3, is a longitudinal vertical section substantially on the line as, m, of Fig. 2.

As shown in the drawings, 1 is a cast metal head formed with a forwardly and clownwardly projecting portion 2, forming the stationary jaw of a clamp for holding the blade 3, t e upper or pivoted jaw 4 being provided at each end with an ear 5 midway between its edges, which ears are pivotally attached to the lower jaw of the clamp. The blade is a metal strip formed with a lower cutting edge 6, which is curved from end to end of the blade so that its corners will not engage and mar the floor. Projecting through a screwthreaded opening in the pivoted jaw near its upper edge, into engagement with the head, is a thumb-screw 7 to rock the jaw on its pivots and clamp the blade between its lower edge and the lower jaw. The blade is thus firmly held and may be quickly and easily inserted, removed or adjusted.

Each end of the head is cut away to form recesses 8 for the supporting wheels 9, said wheels thus lying within the plane of the ends of the head, and in the head near each recess is a vertically extending bore or socket 10 in the lower end of which fits a plug or block 11 to slide freely therein. Stub-axles 12 upon which the wheels are carried consist of bolts extending through. vertical slots 18 in the head and screwed into screw-threaded o enings in the blocks. Coiled springs 14 in t e sockets above the blocks exert a force to normally hold said blocks downward with the stub-axles engaging the lower ends of their slots, so that when pressure is applied to the head one or both of the springs will yield and the head be forced downward. To a lug 15 on the top of the head is attached a long handle 16 having a forked lower end to embrace the lug to which it is pivotally at tached at 17 and said lug is formed with a slot 18 at a distance from the pivot to receive a clamping bolt 19 passing through the fork and slots and provided with a winged nut 20 so that the angle of the handle relative to the head may be readily changed and then rigidly clamped in place. The handle is formed at its upper end with a grip portion adapted to be grasped by one hand of the operator to turn the head on the axles and bring the blade into engagement with the floor. Midway between the ends of the handle 16 it is provided with an auxiliary handle 21 extending upward some distance and provided with a grip portion adapted to be grasped by the other hand of tie operator so that while holding the blade in contact with the floor and drawing the device along with the hand which grasps the upper end of the handle 16, with the other hand the operator may press downward upon the intermediate handle putting a pressure upon the head and causing the blade to engage the floor with greater force. By means of the intermediate handle 21, the operator may, by exerting a lateral pressure on said handle, rock or tilt the head laterally, one of the springs 14 being compressed more than the other, causing that end of the head to be lowered any part of the curved cutting edge of the blade may thus be brought into contact with the floor at any time and the operator is enabled to work up close to the wall without stopping to adjust the blade. By a downward pressure, the operator is enabled to increase the cutting effect of the blade at any time, thus obviating the necessity for loo and by making the device comparatively small and light, it is very easily and rapidly manipulated.

Having thus fully describedrny invention, what I claim is:

1. In a scraper, the combination of a head having a vertically extending socket near each end and a slot in each end opening into said sockets, and recesses outside said sockets to receive the supporting wheels, a block slidable in each of said sockets, wheels, axlemaking the head very heavy,

, pins upon which the wheels are mounted exscrew-threaded openings in tending through the slots and engaging the blocks, springs in the sockets engaging the blocks, a blade attached to the head, and a handle attached to the head at one end and an auxiliary handle on said handle and extended upwardly and provided with a grip portion so that lateral pressure thereon will rock said head and compress one end thereof or the other.

' 2. A scraper, consisting of a head formed with vertically extending sockets and vertical slots in its ends opening into said sockets, blocks slidable in said sockets, wheels, pins carried by the blocks extending outward through the slots and forming stub-axles for the wheels, springs in the sockets above the blocks, a forwardly and downwardly extending portion on the head forming a fixed jaw, a movable jaw pivoted to the fixed jaw, ,a blade having a lower cutting edge curved from end to end, means for rocking the movable jaw on its pivots to clamp the blade, a handle secured at one end to the head, and an intermediate handle secured to said handle and extending outward therefrom.

In testimony'whereof I have signed my name to this specification in presence of two witnesses.

JOSEPH C. PELTIER.
