IMPROVEMENT IN MOULDING-MACHINES.

The Schedule referred to in thesevLetters Patent and making part of the same. y

To all whom it mol/y concern:

Be it known that I, ISAAC P. TICE, of New York, in the county of New York, and State of New York, have invented a new Improvement'in Wood-Moulding Machines and I do hereby` declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figurel l, a side view; j

. Figure 2, a side view of the cutter, and a portion of the arbor detached Ilgures.Stand 4, vertical central sections` through the arbor, at right angles to each other; and in Figure 5, a face view of the moulding cut upon the inclined table. A l

This invention' relates to an improvement in woodmoulding machines, particularly applicable to the machine patented to Nathaniel Gear, November 8,1853, and extended in 1867, the object being to improve the adjustment of the cutters and increase the facilities of the machine; and l v g The invention consists 'in constructing the collar between the two sets of cutters intwo parts, the one screwed on to the other, so'that the upper cutters may overlap to any desirable extent on to the lower cutters, and the elevation of the upper cutters be changed without necessarilychanging thelower cutters.

To enable others to construct and use my improvement, I will fully describe the same as illustrated in the accompanying drawings.

A is the frame;

' B, the table; and

C, the arbor or shaft, all constructed and arranged in the usual manner.

, Upon the shaft is xed or formed a lower head, D, to receive the lower edge of the lower cutters d, usually two in number.

' a-a are the upper cutters, also usually two in number.

Heretofore, between the two sets of cutters has been arranged a collar, ina single piece,'iit'ted upon its under side to receive the upper edge of the lower cutters, and upon its upper surface, in like manner tted to receive the lower edge of the upper cutters, a second head, E, being placed on to the shaft,so'as to support the upper edge ofthe uppercutters, and coniined, so as to hold all the cutters in place.

By this arrangement, it will be seen that the collar between the two cutters, being in one piece, renders impossible the adjustment of the upper and lower cutters relatively to each other, a serious d iiliculty in this class of machines, to overcome which, I form acollar, f, which fits closely to the shaft, and with a sleeve threaded so as to receive over it a second collar, h, the lower collar f being itted to receivethe lower edge of the upper cutters a, as seen in iig. 4.

The upper collar h is in like manner fitted to receive the upper edge of thelower cutters d, as seen in iig. 3.

Therefore, by raising or lowering either of the two collars, h orf, the cutters supported thereby may be adjusted so that the lower edge of the upper set will overlap the upper edge of the lower set, as seen in flg.2

In the construction before described, for securing the cutters, it is necessary that the cutters bev of an exact width, that is, the two cutters in each pair, for should one be a little wider than another, the upper head would bear upon the broader one first, and not be able to reach the second, or narrower.

To overcome this difficulty, I construct the upper head E concave upon the upper side, as in figs. '3 and. 4, and bored out, so that while the upper side will Ht closely to the arbor, the lower side of the hole will per- This forms, as it were, a universal adjustment of theV cutters.

In working what are known-as waved mouldings, that is, a surface having a corrugated form longitudinally, the materialY is moved by a pattern to and from the cutter, so as to produce the waved or corrugated surface.

To produce a'still greater variety of surface, I ar.- range a table, H, hinged or secured to the frame'at t, (or may be at the other en d,) so. that the unhinged end may be raisedand set to any desired degree of elevation.

This-inclination, combinedwith the usual means of guiding the, material so as to produce the waved or corrugated surface aforesaid, gives to the moulding au appearance of being carved, as the cutters indicate the incline on themoulding; and this, combined with the waving cut, throws the cutters out, and starts again immediately under the point at which thecutters run .The combination-of the'two collars, fand it, with l their respective cutters, substantially in the manner IsAAc r. Tron.

herein set forth.
