JOHN DAVIS, OF ALBANY, NEW YORK.
CARVlNG-MACHINE.
SPECIFICATION forming part of Letters Patent No. 336,096, dated February 16, 1886. Application filed November 23, 18 85. Serial No. 183,792. (No model.)
To all whom, it may concern.-
Be it known that I, JOHN DAVIS, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented a new and useful Machine for Carving Lumber or Metal, of which the following is a specification. 7
My invention relates to a machine for the purpose of turning, carving, and ornamenting lumber or metal; and the object of myinvention is to produceasimplemachine,which will carve or turn a panel or other piece of lumber or metal quickly, positively, automatically, and without the use of lathe and chisel, performing its work directly, without the necessity of a skilled mechanic to operate it. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 shows my machine in perspective. Fig. 2 shows a plan of my machine through the line 00 0:. Fig. 3 is a vertical section of my machine through the line 1010. Figs. 4 and 6 represent my knife. Fig. 5 is a plan of afcorner-block, showing also a vertical section 0 it.
Similar letters refer to similar parts throughout the several views.
The horizontal frame A, suitably supported, and the uprights B B form the frame of my machine, andmay be constructed as shown in the drawings, or in any suitable manner and of any material.
To the frame A, I attach the bearing G, in
. which revolves the shaft D, carrying the loose pulley E, the tight pulley F, together with the beveled wheel G. The shaft D also revolves in a bearing attached to the frame B. The wheelG is provided witha broad rim, g,which is beveled toward the periphery, being thicker at the concave edge of the rim 9 than at the convex edge. The shaft I revolves in the bearings l and 1 attached to the frame B, and carries at its lower extremity the beveled friction-wheel J, constructed of felt, rubber,
or like substance, or of metal, and near its up per extremity the wheel K, each securely at tached thereto. The beveled wheel J is placed in close connection with the beveled portion g of the beveled wheel G by proper adjustment of their respective bearings, and the beveled portion of the wheels J and G is so proportioned that every part of the rim 9 which faces the beveled friction-wheel J presses against it as they revolve, and the friction generated by the revolution of G against J generated by the revolutions of the wheel K against the friction-wheel L causes L to move. The shaft L has a thread out onto its lower end, upon which the knife M is screwed. The knife M has a nut attached to it, which is threaded to mesh with the thread on the shaft L, upon which shaft it is placed to perform its work.
The knife M',Figs. 4 and 6, is composed oftwo or more inclined blades having their loweredge sharpened and cut in any pattern to make the required ornament, molding, or scroll, which may be required. The blades face in opposite directions, forming the knife into the shape of the letter Z, Fig. 6, the horizontal portions representing the blades.
The knife may be made as above described,
which is the preferable way, or it may be a' common molding-knife, and yet accomplish the object of my invention.
When the belt is placed on the tight pulley F, and the machine is at work, the beveled wheel G revolves, causing, by the friction generated, the beveled friction-wheel J, against which it presses, to revolve, and the beveled frictionwheel J being smaller in circumference than the wheel G revolves much faster than G. The wheel K being attached to the shaft I is thus set into motion, and as it presses against the 9 friction-wheel h the friction-wheel Lis caused to revolve, and therefore the shaft L, to which it is attached, and therefore the knife M, which is attached to it. A very high rate of speed is obtained by my arrangement of the wheels G, J, K, and L. The beveled wheel G being larger than the friction! wheel J5 causes it to revolve many times to every revolution of the beveled wheel G, and the wheel K being much I larger than the friction-Wheel L causes L to make many more revolutions than the beveled friction-wheel J. I have thus obtained five thousand revolutions of the knife per minute.
The advantage gained by causing the machine to be run by friction rather than by belt and pulley, or by cog-pulleys, is that the belts cause jogging and an uneven motion to be, imparted to the wheels, caused by the seams of the belts, and also by the uneven wearing of their surface. caused when toothed pulleys or cog-wheels are used for gearing. By friction-power, applied as herein described, all that tremor and uneven motion is reduced to. a minimum, and the result is a perfectly uniform and even Inction. This uniformity of motion is, necessary in performing the work for which my machine is designed. The knife must cut perfectly true and evenly or the panel, corner-piece, or
.molding will be out of proportion, rough, and
practically useless.
I For the purpose of holding the piece of wood or metal in position for cutting, I have provided a vise and means for operating it,which I now proceed to describe. To each of the jaws N N of the vise is attached on the under side a notched rack, N N,which mesheswith the cogs on the wheel N Along the under edges of the jaws N N is placed a strip, of wood or metal, 11., which forms with the jaws N N a groove, and into this groove the tongue n. is placed. The tongue 12 is attached to the board ortable Q. TheleverPisimmovablyattached to the cog-wheel N just beneath the table 0.
The mouth of the jaws N N may be made to lit a square block, as shown in Figs. 1 and 2, or they may be, made to conform to the shape of the pieceupon which the work is to be performed. As the lever P is turned, it being attached to the cog-wheel N the cog-wheel N is turned, and the notched racks. N N, meshing with the cog-wheel i and attached to. thejaws N N, the jaws N N are moved toward each other equally, thereby keeping the center line of the block or piece to be operated on in common at all times with the center of the machine. This is a very important feature of my machine, and in turning cornerpieces and panels it is a most necessary one.
The jaws N N of the vise may be easily removed by simply turning the lever P until the racksN N are out of the meshes of the cog-wheel N, and one of the racks N may be placed in contact with the cog-wheel N after the other has been moved toward the center of; the machine a short distance, in order to place the corner or side of a block in the center of the machine for the purpose of ornamentingthe block after the panel or cornerpiece proper has been carved.
For the purpose of raising and lowering the The same uneven motion is vise to and from the knife,I attach to the table 0 an'upright, O, which slides freely in the grooves O' O". The upright 0 may be QQnStructed of wood or metal, and to it is attached the lever Q. The lever Q is attached .to, the, link Q, which said link Q is attached to the frame B. The link Q acts as a movable fulcrum for the lever Q, and when the piece to be carved is placed into the vise and the jaws closed tightly against it,by operating the lever P the vise is raisedinto the position shown in Fig. 1', by pressing down, on the lever Q. and the work is brought into contact with the knife M'.
-In order that the operator may know when the piece is sufficiently cutand may gage his work, a movable clamp, R, is attached to the frame B, which, by means of a-slot and screw, can be. adjusted to meet the requirements of the occasion.
The operation of my machine is so simple. that an unskilled hand can operateit, and yet; so complete that it can perform the work "re quired of it more perfectly than the mostskilled mechanic with any other; machine in use.
For the purpose of showing the operation of my machine, place a blookor piece to be. cut, as shown in Fig. 5, between the jaws N N of the vise, turn the lever B, closing the, jaws tightly and equally against the block, the center of the block and the center of the, knife being in the same vertical line, press. down on the lever Q, raising the vise and block, bringing the block into contact with the .knife, the knife being attached to. the shaft L, which is securely attached to. the friction-wheelv L, and the friction -wheel L pressed against by the wheel K, which is attached to the shaft I, which carries the bev-- eled friction-wheel J, operated upon by the other method or machine now in use, to my knowledge, and turn out a better, smoother,
and more perfect job.
