DEVICE FOR DRESS ING AND JOINTING THE TEETH OFSAWS.
SPECIFICATION forming part of Letters Patent No. 376,647, dated January 17, 1888. Application filed April 13,1887. Serial No. 234,707. (No model.)
ing the Teeth of Saws, of which the followingis so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had tothe accompanying drawings.
This invention relates to a device for dressing and jointing the teeth of band, gang, circular, and, in fact, any of the various kinds of saws now in use, the object being to construct a device which will combine in itself the advantages of cheapness, accuracy, rapidity, and the accomplishment of its purpose with out the necessity of especially-skilled workmen.
To this end my invention consists in certain peculiarities in the construction, arrangement, and combination of the various parts, substantially as will be hereinafter described, and then more particularly pointed out in the claims.
In the annexed drawings, illustrating my invention, Figure l is an end elevation of my improved device for dressing and jointing the teeth of saws. Fig. 2 is a top plan of the same. Figs. 3 and 4 are a side and a plan view, re-
I spectively, of one of the holders for the files used inside for dressing the saw. Fig. 5 is a perspective. Fig. 6-is a detail representation of the device for jointing saw-teeth.
Like letters of reference denote corresponding parts in the several figures.
. In my improved devicefor dressing or sharpening and jointing the teeth of saws, A represents the supporting-frame, which is preferably composed of the standards a a, made of a proper height and standing parallel to each other, which standards are connected with each other by a cross-piece, a and are secured to a suitable base-piece, as o the whole being completed by the strengthening-pieces or, a. Thissupporting-frame is adapted to be secured in any suitable manner to a table or bench for convenience in using it. Situated within this supporting-frame is a saw-clamp, B, mounted on a set-screw, B, which set-screw extends downward through a perforation formedin the connecting-piece and in the base-piece a and through the table or bench upon which the device rests,being operated from beneath said table or bench in any desirable manner. This clamp B is formed with a groove or slot, b, within which groove or slot the saw to be operated upon is placed, being held securely from lateral movement therein by means of the setscrews G C, or other suitable devices, hearing against the sides of the said saw and forming guides therefor, the upper side of the saw-blade being guarded against any lateral movement by the set-screws O O,situated a suitable distance from the top of the device. Obviously by this arrangement of screws the device can be accommodated to saws of any thickness.
. Referring now to Figs. 3 and 4 of the draw ings, which figures are detail views of the device for-dressing or sharpening the teeth of the saws, D represents one of the files, which file is leveled at d for the purpose of leaving a smooth surface, against which the saw-blade abuts when the file-holders are inclined,in the manner to be hereinafter described. These files are securely held within suitable devices, as E, preferably made in the form shown, by means ofsetscrews D. The file-holders E are situated within the frame, one on each side of the same, in alignment with each other, as seen best in Fig. 1. They are pivoted at their rear portions to arms F, Fig.4, which,when the devices are situated in position within the frame, project out through slots in the sides thereof (see Fig. 1) and facilitate the adjustment of file-holders E to suit saws of different thicknesses. These arms F are held in position in the supporting-frame, preferably by means of the screwf. In Fig. 4 I have shown the file-holders E as-fulcrumed between bifurcated portions of the arms F, although any other mode which is suitable for the purpose may be adopted, if desired. The object of thus pivoting the file-holders E to the arms F is to enable the said holders E to be adjusted to any desired level or inclination,which adjustment is accomplished by means of set-screws G G, projecting obliquely through the sides of the standards and bearing against the lower edge oil the tile-holders. The portion of the standards a a which receives the arms upon which the file'holders are fulcrumed is, for the sake of beauty and of strength, preferably made of a greater width than the other portion.
When it is desired to dress or sharpen the teeth of ordinary saws, I proceed as follows: The saw is placed within the groove or slot of the clamp with its back resting upon the bottom of said groove or slot and its teeth projecting upwardly, and the set-screws O O are screwed up so that they will bear against the sides of the saw, forming a guide for the same and preventing any lateral movement. The set-screws C O are next screwed up against the upper side of the saw in a like manner and for a like purpose as the screws 0. The file-holders E are next adjusted up to the saw by means of the arms F, which are secured by set-screws f, and the proper level or inclination is given to the said file-holders, and consequently to the files, (which have been previously secured therein,) by means of the setscrews G G, as heretofore described, and the saw-blade is moved backward and. forward against the files until all the projecting or rounding corners are cutaway and the saw thoroughly sharpened, leaving the set of the teeth very accurate and parallel from end to end of the blade.
I have thus described my mode of dressing or sharpening the saw-teeth, and I will now proceed to describe the manner in which. I joint the same.
Upon the top of the standards a a, and fastened thereto in any desirable manner, (preferably by thumb-screws h h, as shown, so as to permit of its being readily attached and detached when necessary,) is a holder, H, for carrying the jointing-file I, which jointing-file is situated within a transverse groove or slot formed in the under side of the said holder, and is securely held therein by means of a key, I, thus facilitating the removal and replacement of the files.
When it is desired to joint the saw-teeth, the saw, through the medium of the clamp 13, is raised up into contact with this jointing-file I by means of the set-screw B, as heretofore described, and the saw is then moved backward and forward, in the same manner as in sharpening, until all of the points of the teeth are filed down into alignment with each other.
In order to operate upon the teeth of end less band-saws, the holder H is removed, so as to admit the said saw into the device. This device not only combines within itself a clamp and devices both for dressing and jointing the saw-teeth, but it combines them in such a manner that the different devices can be readily attached and detached when desired, and any of the files can be easily removed from said devices and replaced by others, and, further, it can be readily adapted to operate upon any of the various kinds of saws now in use, and upon saws of any thickness and size.
Taken in connection with these advantages is the fact of its chcapncss and the high degree of accuracy capable of being attained by it, and that it does not require the aid of an especially skilled workman to use it, but can be operated by any ordinary person, which is a great dcsideratum, as it saves the expense of having it done by some one skilled in this line of workmanship.
llaving thus described the uses, purposes, and construction of my invention, what I believe to be new, and desire to secure by Let ters Patent, and what I therefore claim, is
1. The combination, with the supportingframe, of a saw clamp having a groove or slot for the reception of the saw, and setscrews in the said frameand clamp for guiding the saw and to keep it from lateral movement, substantially as herein shown and described.
