GIUSEPPE ANDREOTTA DISEPO, OF PASSAIC, NEW JERSEY.
SPECIFICATION forming part of Letters Patent No. 754,753, dated March 15, 1904.
Application filed December 12, 1903. Serial No. 184,852. (No model.)
To all whom it may concern:
Be it known that I, GIUsnPPE ANDREOTTA DIsnro, a subject of the King of Italy, residing in Passaic, county of Passaic, and State of New Jersey, have invented certain new and useful Portable Mortising Chain Cutters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which forma part of this specification.
This invention relates to improvements in drilling-tools especially applicable for drilling or cutting substantially rectangular-shaped holessuch, for instance, as the holes in doors into which the door-locks are secured or the lock-holes in cabinet or closet drawers, &c.
The object of the invention is to provide such a drilling-tool of simple, strong, and
durable construction, reliable and quick in operation, easily handled and adjusted, and not liable to get out of order.
The invention consists in the improved drilling-tool, its drill or cutter operating and feeding mechanism, and in the combination and arrangements of the various parts thereof, substantially as will be hereinafter more fully described and finally embodied in the claim.
' In the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a top plan view of my improved tool; Fig. 2, a side elevation of the same; and Figs. 3, 4, 5, 6, and 7 are enlarged detail views of certain parts, as will be hereinafter more fully pointed out.
In said drawings, a represents a substantially rectangular-shaped frame provided atprovided with downwardly-projecting lugs g, forming the bearings for the shaft k, which latter penetrates the frame a and is slidingly arranged in the elongated slots a, as clearly shown.
On the shaft 7L, which is operated by means of the crank-handles it, is securely mounted a beveled gear 2', meshing with beveled gear on on shaft 11,, the latter having its hearings in the frame f. The gear 2' meshes also with a gear 0, secured on the feed-screw p, which latter penetrates the internally-threaded sleeve q, removably arranged on the cross-piece r, and is held in position by means of the hinged lid 8, as will be manifest.
On the vertical shaft n are secured sprocketwheels 2, engaging the links of endless sprocket-chains 4, which latter are also en gaged by the sprocket-wheels 6, which are revolubly mounted on avertical shaft 7. The last-mentioned shaft is secured in and penetrates a bar 3, which bar projects from the frame f, as clearly shown in the drawings.
Said bar 3 is guided through the block 10, ad-
justably arranged in the frame a by means of thumb-nuts 12, engaging screws 11, projecting from the guide block 10 through the frame a.
Integral with the sprocket-wheels 6 are cylindrical-shaped cutters 5, held in operative position on the shaft 7 by means of screws 8, as clearly shown in Fig. 5. The endless chains 4, heretofore mentioned, carry a number of cutters 15, adaptedto cooperate with the cutters 5, and it may be well to remark that each link of the endless chains is likewise a cutter in itself.
For the purpose of getting the correct depth of the hole to be drilled an indicator or pointer is, secured on the .block f and a scale on the frames (0, as shown in Fig. 1. I
The operator after having secured the clamping end of the drilling-tool to the edge of a door, for instance, presses his loodj against the handle or shield b and turns the crank-handles it from right to left. This rotates the shaft 12, which in turn through the endless chains rotates the cutters 5. Simultaneously the endless screw 10 is rotated through the beveled gear connection 0 and i,
moving the frame f forward, and thus the cutters 5, as will be manifest.
I do not intend to limit myself to the precise construction shown and described, as vari- 5 ous alterations can be made without changing the scope of my invention; but
That I claim as new is In a portable mortising chain cutter, the combination with an elongated frame, open at a I one end, and provided with oppositely-arranged elongated slots, a crank-shaft penetrating said slots, a sliding carriage mounted on and forming bearings for said shaft, a second shaft revolubly mounted in said carriage I5 and at right angles to the crank-shaft and receiving its motion from the latter, sprocket wheels on said second shaft, a bar projecting from said carriage, a shaft penetrating the free end of said bar and secured therein, a
20 cylindrical-shaped cutter on each side of the bar and revolubly mounted on the last-mentioned shaft, a sprocket-wheel connected with each of said cutters and in closeproximity crank-shaft for rotating said screw, all said parts, substantially as and for the purposes described.
In witness whereof I have hereunto set my I hand in the presence of two witnesses.
