Apulieationfiled March 8. 1906. Serial No. 304.937

To all whmn it may concern.-

Be it known that I, JUsTUs A. TRAUT, a citizen of the UnitedStates, residing at New Britain, Hartford county, Connecticut, have 5 invented certain new and useful Improvements in Scrapers, of which the following is a full, clear, and exact description.

My invention relates to improvements in scra ers.

T e object is to facilitate adjustment of the parts and improve the construction so that it may be adapted to use .under many different circumstances. I have sought to construct the parts so that they may be manufactured readily and assembled or taken apart without diificulty.

The referred form of the invention is shown 1n the accompanying single sheet of drawings, in which Figure 1 is a side view of the scraper embodying the improvements of my invention. Fig. 2 is a front view of the same. Fig. 3 isa rear view of the scraper with the handle shown in section. Fi 4 is a rear view of the back member of the head. Fi 5 is a side view of the same. Fig. 6 is a p ar. view of a fragment of the handle.

The handle is preferably formed in two ortions-a grip member 1 and a body mem- The head of the scraper carries the blade 3 and is preferably provided with an auxiliary grip or handle 4.

5 and 6 are the frontand rear members,-

respeetively, of the head, between which the blade is clamped.

7 is a screw located between the upper and lower ends of the plates 5 6. This screw passes freely through plate 5 and takes into plate 6, so as to produce, in effect, a hinged joint which may be adjusted to and fro to vary the widths of the space between plates 5 6. r

8 8 are screws arranged at opposite edges of the plate 6 and screw-threaded therein. The ends of these screws project into cavities in the opposite face of the member 5, but are not screwthreaded therein. The

function of these screws is to preserve the alinement of plates 5 6 and to act as s acers to uaranteev the substantial parallellsm of sai plate, whereby the ready substitution of blades 3 is permitted. The screws 8 8 alsoperform a stop function, the upper edge of the blade 3 taking a bearing against said screws so thatv blade will be projected'uniformly from the clamping-jaws. These stop-screws. '8 8, as we shall term them, may be shifted'up or down on late 6, there being a series of screw-holes a ong opposite edges thereof to permit this shifting of the screws to be made. By this meanswhen blade 3 wears down or if a short blade-is to be substituted the screws 8 8 may be moved to any one of the holes 8, 8 or 8 so as to adapt the holder to the particular blade to be used.

9 is a main adjusting-screw having a stophead whereby it may beeasily operated. When approximate adjustment of the plates 5 6 has been secured by the adjustment of screws 7 and 8 and the blade inserted, the user may set u on screw 9 in such a manner as to powerfu 1y clamp the blade 3. The rear of the back member 6 of the head is provided'with a pair of lugs 10 10, to which the handle is pivoted.

11 is a curved arm extending from the rear of the back member and provided with a curved slot. This arm is preferably formed of a separate piece of metaland riveted to the lug 12.

13 is a screw. preferably provided with an enlarged head for engagement b the thumb Patentedjan. 29, 1907.,
