IMPROVEMENT IN CUTTER-HEADS FOR PLANING 0R MOLDING MACHINES.

Specification forming part of Letters Patent No. 12,791, dated September 16, 1873; application filed April 17, 1873.

To all whom it may concern:

Be it known that I, JAMES D. KIMBALL, of Reading, in the county of Middlesex and State of Massachusetts, have inventedcertain Improvements in Gutter-Heads for Planing 0r Molding Machines, of which the following is a specification:

Figure 1 of the accompanying drawings is a top view, and Fig. 2 is a side view, of my improved side head of a molding or other cutting machine.

This invention has for its object to effect an improvement in the means employed for attaching cutter-heads of molding-machines to their spindles, whereby each side of the head is adapted to hold a cutter of ordinary construction; and to this end the invention consists in providing the spindle with a longitudinal groove, and the cutter-head with a screw entering its top obliquely in such manner as to engage with the groove and hold the head in place, thereby leaving the sides of the head unobstructed for the reception of the cutters, as I will now proceed to describe.

In the drawings, A represents a spindle formed with a groove, B, and receiving a side head, 0, formed on each side with a vertical T-slot, K, and on the top, at one corner, with an oblique screw-aperture, with the threads of which mesh the threads of a screw, l), whose bottom end is made to impinge against or be released from the spindle, according to the direction in which the screw D is turned. The top of the head is formed, as usual, with a collar or screw-socket, E, formed with a seat for a screw-nut, F, that operates up and down, so as to hold in any desired position a vertical screw, G, which is operated up and down in the socket E, and. bears against the top of the spindle A, so as to raise or lower the side head 0.

Heretofore much objection has been made to the ordinary arrangement of side heads of molding or cutting machines, on account of the location of the set-screw in one side of the head, and the consequent arrangement of the tap-bolts of the cutter on either side of it, when desired to use an additional cutter, which made it impossible in many cases to affix more than two cutters to the head without altering the formation of the cutter to be adjusted to the set-screw side of the head, and thereby necessitating the employment of considerable time, labor, and expense.

By the above description, reference being had to the drawings, it will be seen that these objections are obviated in my improvements by slotting each side of the head and locating the set-screw so as to be operated in the top of the head, thus allowing cutters to be adjusted to all sides of the head without altering their formation, and thereby permitting a great variety of work to be performed with no extra trouble or expense.

Having thus fully described my improvements, what I claim as my invention, and desire to have secured to me by Letters Patent, is-

The spindle A, having the longitudinal groove B, in combination with the head 0 and oblique screw D, all arranged and operating substantially asdescribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES B. KIMBALL.
