IMPROVEMENT IN VARIETY-MOULDIN G- MACHINE.

The Schedule referred to in these Letters Patent andV making part of the same To all whom it may concern Be it known that I, NICHOLAS JENKINS, of the city and county of New York, State of New York, have invented certain new and useful Improvements in Machines for Variety-Moulding in food Vorking; and I do hereby decla-re that thc following is a full and exact description thereof.

My invention relates to the table or part which sus- .tains the wood to be moulded, and to certain devices connected therewith, in their several relations to the cutting-arbor or arbors, and to each other, in the production of such light panelling or moulding as does not require the leverage `due to the use of the moving tables.

I will first describe what I consider the best means of carrying out my invention, and will afterwards designate the points which I believe to be new therein.

The accompanying drawings form a partof this specification.

v Figure l is a front view, Figure 2 is aplan view, Figure 3 is a side view, and Figure 4 is a vertical section scale.

of a part on a larger ing my table in position therein. A part ofthe framing is broken away to better show the situation of the table.

Similar letters of .reference indicate like parts in all the figures. Tint-s are used merely to distinguish parts, and do not imply material. The material of the whole should be iron or steel.

The general construction and arrangement of the other parts of the machine may be substantially that described in niy'patent dated August 6, 1867. There are, however, some important peculiarities in the best t'orm of the machine as represented, and I will briey explain some of them. They are only important so far as they relate to the movin r table upon which my fixed table is partly supported, and tothe cutter-arbors which treat the wood.

A is a fixed frame.

A1 indicates upright portions thereon, to support the working-parts.-

vA3 is a broad cross-head, capable of being moved vertically on the front of the frame-work, guided by the slides A2, and operated by the screws A4, which are adjustable by the aid of the transverse shaft A5 and the gear-wheels connecting the parts, as represented. As the shaft A5 is turned, the cross-head Aa is caused to rise or sink within wide limits.

B is a cutter-arbor, mounted vertically in bearings carried in the cross-head A3, before described.

I propose generally to use two of these arbors, running in opposite directions, so asto cut right and left,

Figure 5 is a side view of the entire machine, showas preferred, but this is not absolutely necessary, and I will describe them as one. It is rotated by a belt from a corresponding pulley on a back shaft, D, as

represented, and the bearing for the belt on the cutterarbor, or rather ou the long drum or pulley, which is fitted thereon, is sufficiently long to allow the motion to be properly communicated in all positions.

The cutter which produces the mouldings, or the panel-work, may be either plain or variously ornamental, and the operation of moulding or panelling is effected in my machine vas in my former one, by lowering the cutter so as to enter the wood to a proper extent, and then moving the Wood horizontally in various directions, so that the cutter shall excavate a groove either straight or variously curved. The arbor may be raised and lowered to a great extent with facility, and adj usted at any level desired.

E is the movable carriage. 'W'hen used to carry the stuff in heavy work there are frames bolted thereon, adapted to receive the boards or planks to bepanelled or moulded betweensuch frames and movable clamping-pieces. One of these vframes is partially visible near the back end.

This carriage E is moved transversely from right to left, and from left to right on the movable under table or carriage F at will. The undertable Fis traversed backward'and forward longitudinally at will, carrying the other with it.

The proper traversing motion is given to the table F by operating a crank-shaft, F2, and in giving the lateral motion to the upper table E, the crank E* is used.

The above moving-carriages are necessary for the production of heavy work, but for -all kinds of light work I can move the wood by the direct application ofthe hand, movig it longitudinally and laterally, as required, upon a xed table, but it is necessary to enlploy very-ettieient and delicately-adjustable guiding means. This table and guides form my present invention. f

V is my portable or removable table.

It has short supports or legs Vl V, adapted to rest on the transversely-sliding table or carriage E, before described, and longer supports or legs VZ, extending down into holes in the frame-work A, as represented, and adapted to be secured there firmly by means of the collars V3 and nuts V4. Y

I use this table iu variety-moulding, and I fix the wood to be cut upon the pattern which is to guide it. The table V remains immovable during the whole operation, and I move the pattern and the Wood thereon by sliding it about on the table V, pressing it meanwhile against a pin, W, which is xed in the table V, exactly in line with the cutter-arbor, audits cutterprevolving rapidly above, as before described.

The pin W has its upper portion smooth and cylin drical, and so much smaller than the threaded portion below it that it can be sunk into the table 'to any depth desired, and it is peculiarly adjustable. It may be adjusted so as to protrude upward more or less above the surface of the table V, by simply seizing it with pipetongs or any analogous instrument, and screwing it up or down.

The nut NV o n the lower end being setup afterward, confines it very firmly.

In order to change the pin W, substituting a larger or smaller at pleasure, I remove the socket X, and insert another which has a correspondingly larger or smaller hole.

Itwill be understood that I have several sockets X, and several pins W, of different sizes, adapted thereto, the exterior' of all the sockets being alike.

The nut W is of such size as -to extend over or beyond the socket, and to bear on the fixed boss V5, which is a part of the table V, and thus to bind and afford a firm support, and confining-means both for the socket and pin. The tightening of the nut NV' will tighten both the socket and the contained pin. I can, if preferred,obtain nearly the same effect by using a smaller nut and au intermediate washer of suitable size. Vith either arrangement, properly-tightened, the friction of' the threads of the pin Vf, and also of the large sockets X, will confine them with absolute rmness.

There may be a head on the lower end ,of each of the pins W, in which c ase each will, of course, be inserted into its respective socket X from below, and it can be adj usted by applying a suitable wrench or key to the head, instead of seizing the small part of the pin.

Some of the advantages due to certain features of my invention may be separately enumerated, as follows:

First, by reason of' the fact that my removable table V is adapted to form a level surface, when applied as represented, resting atY 'carriage E, and firmly bolted at the other end upon the frame-work A, I am able, with thesame machine,

to secure firmness of support due to an absolutely fixed table, for producing light work, without forfeiting the advantages of the movable carriage, for eecting heavy cutting.

one end upon the traversing ,Second, by reason of the fact that my pins are adjustable vertically by means of the screw-threads thereon, and are fixed firmly in either position by the nut W onthe under side, as represented, I am able to secure the advantages due to a high pin or guide in working ordinary thick stuff, and thus to reduce the risk of riding over it, `and can, by a ready adjustment, adapt the part-s to the treating of very thin stuff. y

Third, by reason of' the fact that the sockets X, in which the adjustable pins W are set, may be changed, as represented, I am able to employ pins of larger or smaller diameter at will, and thus employ pins corre sponding as exactly to the diameter of .the cutter as may be required, without sacrificing the capacity of adjustment of the pins vertically. Any difference in diameter between the guiding-pin W and the cutters 1 z causes the panel-work to differ in design from the patterns, and therebyintroduces confusionwhich this provision avoids,

Having now fully described my invention,

What I claim as new, and desire to secure by Letters Patent is as follows:

1. The removable table V, and pin set therein, arranged to serve relatively to the carriage E, framework A, and cutting-arbonB, and having the plain legs Vl and the screw legs V2, for fixing the table in an invariable position relatively to the said arbor, all as herein set forth.

2. Incombination, the cutter b, raised and lowered as specified, the stationary surface V, and the adjustable pin W, having its cylindrical part smaller V'than the threaded part, stantially as and for the purposes herein set forth.

3. The changeable threaded sockets X, in combination with the changeable pins W, adjustable vertically, as represented, and with the table V and rotating cutter, adapted to move vertically, all substantially as and for the purposes herein set forth.

' In testimony whereof, I have hereunto set my name in presence of two subscribing witnesses.
