ROUTING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 431,513, dated July 1, 1890. Application filed Pebrnary G, 1890-; Serial No. 339,498. (No model.)
work and to work faster than with the ordinary form of machine.
As is well known, these machinesusually.
consist of a table, above which is mounted in any suitable manner a series of arms connected together by such an arrangement of pivots that one of the arms (the last in the series and the one carrying the tool) may be moved in any direction over the table. The power is transmitted to the tool by means of belts passing around pulleys arranged at the several pivots. For the purpose of moving the tool about over the table two handles have been provided, and for the purpose of adj usting the tool vertically the same has been mounted in movable bearings which are adjusted by means of a screw carrying a handwheel on one end. In the operation of routing it is necessary at short intervals to adj ust the height of the tool, and in order to do this it has been necessary for the operator to stop the movement of the arm carrying the tool, to let go one of the handles, and then by means of the hand-wheel raise or lower the tool. This having been done, the handle is again grasped and routing continued; but the new channel which is then out is of a different depth from the one previously cut, and there is therefore left in the channel a step or shoulder, which is objectionable for several reasons.
My invention is designed to enable the operator to adjust the tool without discontinuing the routing operation, thereby saving time and producing smooth work.
The invention will now be described with reference to the accompanying drawings, in which- .are pivoted together at b.
chine fitted with my improvements; and Fig. 5o
-2, a side elevation of the frame carrying the tool, alsoshowing my improvements.
Referring tothe drawings by letter, A represents the table. This is fitted with the usual clamping devices for securing the work. On the table is mounted the two arms B B',which The arm B is pivoted to a suitable frame-work at b. The arm B carries the tool 0, which is set in vertical bearings c 0', attached to a vertically-adjustable bracket C. This bracket is adjusted by -1neans of a screw-shaft 0', upon the upper end of which is a wheel 0 0 represents the pulley, over which the' belt 0 passes to drive the tool.
The outer end of the arm B is extended and used as a handle to aid in swinging the arm about. upon a ledge D, extending across the front of the table. It may, however, be lifted above this ledge for the purpose of removing the tool from the work. Besides this extensionhandle there has ordinarily been provided a second handle. (Shown in the drawings in dotted lines and lettered d.) Now in the operation of raising and lowering the tool the operator had formerly to let go the handle d and turn the wheel 0 While he was adjusting'the tool he could not control the movements of the arm, and the work had necessarily to stop during the adjusting operation. In my invention I do away with the handle d and substitute for it another handle E. This handle is placed at right angles to the arm B,
and is therefore in a position to give purchase to the hand in removing the arm. The handle E is supported in journal-bearings at the lower end of the bracket E, which is bolted to the arm B at any desired point thereon. The handle E is continued through the hearing in the lower end of the bracket in the form of a shaft and has mounted on its further end a pulley 6. At the upper end of the bracket E are placed two guide-pulleys e e, and the usual hand-wheel, which is placed on the upper end of screw-shaft O, is substi- This arm normally rest-s tuted bya pulley 0 Now over this set of pulleys is placed a continuous belt 6 which, when the handle E is turned, transmits mo tion to the screw-shaft O, and thus effects the vertical adjustment of the tool.
In manipulating this apparatus the operator grasps the extension-handle at the end of arm B and the handle E and guides the tool thereby. When it is necessary to raise or lower the tool, he simply twists or turns the handle E. This operation can be performed while the arm B is moving, these two movements of the tool occurring simultaneously to produce a gradual change from one depth to another in the work, instead of a step or shoulder therein, as has been the case heretofore. It will be observed that inasmuch as the adjustment of the tool is accomplished simultaneously with the movement through the Work a considerable amount of time is savedthat is to say, the work of routing proceeds uninterruptedly.
I do not limit myself to the location of the bracket 0 or of the handle, as it is quite obvious that the same might be placed at any point desired upon the arms 13 B. The fundamental idea of my improvement consists in gearing a rotatable handle to the tool-adjust ing device. A
I show the bracket E as secured to the arm by means of bolts; but it is obvious that any form of clamping device may be substituted therefor. By constructing my improvement in this way I am enabled to readily attach it to any of the ordinary routing-machines, the
only change necessary to make being the substitution of a pulley for the hand-wheel.
Having thus described my invention, I claim 1.-In a routing-machine, the combination, with the tool-carrying arm and devices for adjusting the tool vertically, of a guidinghandle connected to and movable upon said arm, and connections between said handle and adjusting devices whereby motion of the guiding-handle upon or independently of the arm' will adjust the vertical position of the tool, substantially as described.
2. In a routing-machine, the combination of a rotatable handle and a rotary-shaft for adjusting the vertical position of the tool with an endless belt transmitting motion from the handle to the shaft, for the purpose mentioned.
In a routing-machine, the combination of the arm carrying the tool and the adjusting devices therefor with a bracket secured to the arm, a handle mounted in bearings in said bracket, a pulley on the end of the handle, guide-pulleys also carried by the bracket, and a belt passing over the pulleys and transmitting motion to the adj LlStlllg devices,substantially as described.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
