LSMASQ CHARLES HROMAS, OF ll/IINOT, NORTH DAKOTA.
FLOOR PLANER OR SGRATPER.
Application filed September 1., 1925. Serial No. 53,956.
This invention relates to tools, and particularly to floor planers or scrapers.
The general object of the invention is to provide a device having a blade and a handle whereby the blade may be drawn over the surface of the floor to thereby scrape or plane away the upper surface thereof toeven the floor.
A further object is to provide a device of this character so constructed that the handle may be adjusted into a plurality of angular relations to the plane of the blade.
A still further object is to provide means whereby the handle may be held rigidly in its adjusted position.
Another object is to provide means where by the blade may be supported in connection with the handle so that the blade may be removed or replaced or longitudinally adjusted.
Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevation of a floor planer or scraper constructed in accordance with my invention;
Figure 2 is a vertical sectional view thereof; i
Figure 3 is a transverse section;
Figure 4 is an under side plan view of the structure shown in Figure 1;
Figure 5 is a top plan view of the plate and the blade, the bolts being in section;
Figure 6 is a section on the line 6-6 of Figure 2-.
Referring to this drawing, 10 designates ametallic plate constituting a blade carrier, this plate being formed at its margins with overturned lugs 11, there being preferably four of these lugs disposed at the corners of the plate 10. The blade is intended to be disposed within these lugs and engaged thereby. The upper face of the'plate is formed with outwardly projecting stud bolts 12 having nuts 13, and disposed upon the face of the plate and engaged by said bolts is the outwardly bowed yoke 14. the ends of this yoke being disposed in a plane parallel to the plane of the plate 10 the bolts passing through this plate and the nuts 13 hearing against the plate. The middle bowed portion of the plate is slotted, as at 15. The middle portion of the plate 10 immediately beneath the bowed portion of the yoke 14 is formed with a longitudinally extending slot 16 having therein a locking plate 17 whose inner faceiscorrugated at 17*.
Extending; from the yoke 141; is the tubular handle 18. This is'preferably of wood. and has a central, longitudinally extending bore. Extending through the bore of this wooden handle is a tubular bushing 18 termine-ting at its inner end in a transversely curved head 19, the curvature of this head being the same as that of the yoke 14-. This head 19 has an aperture in its center, and disposed through this aperture and through the bore of the bushing is a locking rod 20 which is pointed at its extremity and adapted to engage in any one of the'corrugations 17. This locking rod is loose within the bore of the bushing. The outer end of the bushing is. interiorly screwthreaded, and engaging this outer screwthreaded'end is a locking screw 21 having a head or handle 22. When this locking screw is turned home it will bear against the extremity of the rod or pin 20, forcing this rod or pin into engagement with the corrugations 17 and locking the yoke and the plate 10 in any desired. angular adjusted relation to the handle within the range of the mechanism. When the screw 21 is turned in the opposite direction, it will release the locking pin 20 and then the handle may be shifted.
It will be seen thatthe yokelt is disposed between the outer face of the semicylindrical head 19 and a semi-cylindrical. recess 23 formed in the extremity of the wooden handle 18. The bushing 18' is preferably rectangular in cross section adjacent the semi-cylindrical head 19 so that the yoke will be held from any oscillation upon the end of the handle in a plane at right angles to the axis of the handle but may oscillate in the plane of the slot 15.
As shown in Figure 9,, the locking plate 17 is rabbeted at its. ends, as at 17 and the ends of the slot 16 are beveled, as at 16 to receive the rabbeted or beveled ends of the locking plate 17. When the pin 20 is forced inward by turning the screw 21, it will force this locking plate inward, causing it to bear against the blade 24 and lock this blade in its adjusted position between the locking plate 17 and the jaws 11. When the pin 20 is retracted, the blade may be shifted by means of a hammer or other implement longitudinally through the looking jaws to any desired adjusted position.
It will be seen that the plate 17 constitutes not only a means for holding the handle in adjusted position with relation to the blade and blade holder but also the means whereby the blade is locked from movement within the blade holder. The adjusting means which I have (..-SC1llO6(l permits the blade to be adjusted either into an oblique angle to the axis of the handle or an acute angle thereto, whichever maybe desired.
The manner or" using the blade will be obvious to those skilled in the art and needs no specific description. The tool is ren dered particularly convenient by the fact that the blade may be angled within certain range in any desired angle to the handle and that the blade may be shifted through the blade holder to any desired extent and that it is an easy matter to take out blades and put in new ones in case of necessity.
I claim 1. A planer and scraper of the character described comprising a blade holder, 2. handle therefor, and means for clamping the blade within the holder, and means for holding the handle in any one of a plurality of angular relations to the blade holder and blade, said means including a locking rod having. screw-threaded engagement with the handle, extending entirely through the handle, andprovided with means whereby it may be rotated independently of the handle.
2. A, scraper and planer of the character described comprising a blade holder, an. arcuate longitudinally slotted yoke mounted thereon, a handle, means carried by the handle engaging said yoke whereby the handle may be shifted and permitting the handle to be shifted over the yoke parallel to the slot into any one of a plurality of angular relations to the blade-holder, and a locking rod extending through and having screwthreaded engagement with said handle whereby the handle may be locked in its adjusted angular position, said locking rod having operative engagementwith the plate disposed in said hole and holding the plate in adjusted position. v
3. A scraper and planer of the character described comprising a blade holder, an arcuate yoke mounted thereon, a handle, means carried by the handle engaging said yoke and permitting the handle to be shifted over the yoke into any one of a I plurality of angular relations to the blade holder, means extending through said hanholder for oscillation into a plurality of planes angular to the blade holder, means for locking the handle 111 any one of a plurality-of angularly adyusted positions and locking the blade within the'holder includ-' ing a bushing carried by the handle, a corrugated locking plate carried by the blade holder and adapted to bear against the blade, a rod carried by the handle and extending longitudinally therethrough and engaging the corrugated face of said plate, and screw means carried by the handle adapted to engage said rod and shift it inward into engagement with the teeth of said plate. I
5. A scraper and planer of the character described comprising a blade holder having inwardly turned lugs upon its face adapted to embrace a blade and formedwith a longitudinally extending slot in its middle, a yoke attached to the rear face of the blade holder and arching thereover and having a longitudinally extending slot, a handle having an arcuate head disposed within the yoke and bearing thereagainst, the shank of the handle passing through said slot of the yoke, a locking plate disposed within said slot of the blade holder, a sleeve forming part of the handle extending longitudinally therethrough and engaged with said head, the outer end of the sleeve being interiorly screw-threaded, a locking rod extending through the sleeve and at its extremity engaging with .the corrugations of said plate, and a screw engaging the screw-threads of the sleeve and having a head, the screw bearing against the extreinitly ofsaid rod;
Intestimony whereof I hereunto affix my signature.
