SPECIFICATION forming part of Letters Patent No. 735,825, dated August 11, 1903.
Application tied May 1s, 1902. serie No. 107,206. N0 moda.)
zen of the United States, residing at Oxford,
in the county of Johnson and State of Iowa',
have invented certain new and useful Im-A provements in Rasps; and I do hereby declare the following to be a. full, clear, and eX- act description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to raspsfor the use of woodworkers, Vhorseshoers, and the like; and the object of the invention is to produce' a sectional rasp adapted to cut rapidly and so constructed that any section may be re-` newed when broken or worn out and sharp-1 'minate in an angle; but when worn dull the sections may be resharpened by grinding,
ened by grinding when dull.
The nature of the invention is fully disclosed in the description and claims follow; ing, reference being had to the accompanying drawings, in whicl1 Figure l is a top view of a rasp embodying my improvements. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a top View of one of the sections enlarged. Fig. 4 is a side View of the same. Fig. 5 is a plan view of the same.
The rasp which forms the subject of this in? may of course be accomplished in a varietyV of ways; but one of the simplest is that shown in the drawings. In this case the sections and blanks are perforated at C to take a rod E,
on which they are strung. The end of the vrod is threaded at E to take a nut D at the end of a handle D, by the screwing up of which the sections and blanks are tightened' in place.
In practice the sections are arranged to lie diagonally with respect to the rod, Whose longitudinal center may be regarded as their axis-that is to say,two edges of the sections are diagonal and two practically atV right angles to the axis inthe case of rectangular sections. The rod is accordingly provided at its outer end with an inclined head E2, and at the other end of the series of sections an inclined washer F is interposed between the sections and the handle.
respectively. to be pushed and for the other side drawn, as
This
4section havin g'teeth formed yin one or more of The sections are serrated at one or more of their edges. In Fig. 5 three edges are shown serrated and one plane. The latter may serve as a blank face for the rasp or by sharpening may serve as a scraper-.for nishing. The
serrations on the side A are in no wise peculiar, but in the case of the diagonal sides A2 the teeth are dressed with their sides diagonal to the plate or section, but when mounted in the rasp parallel with the axisthereof. This not only gives suitable clearance to the teeth, but gives to the fronts thereof diagonal cutting edges, which in practice are very efficient and rapid in action. The backs of the teeth are ground diagonally, as shown at A3. "In` the case of a new rasp the teeth would ternbe almost as rapid inexecution as at rst. "The other two edges of the sections have, as
vshown in Fig. 1, front rake and back rake, For one side the rasp Will need l.will Vbe Obvious.
Having thus described iny'invention, what -I claim as new, and desire to secure by Letters Patent, is p 1. As a new article of manufacture, a raspits edges, the sides of the teeth being dressed vkliagonal to the faces of the section, and practically parallel to each other, substantially as and for the purpose set forth.
2L As a new article of manufacture, a raspsection having teeth formed in one or more of its thin sides, the sidesof the teeth being dressed diagonal to the faces of the section and parallel with each other, and the backs of the teeth beveled to render them sharp, substantially as described. A
In testimony whereof I afiix my signature in presence of two witnesses.
JOHN H. ROHRET.
