UNITED STATES PATENT OFFICE.

ALBERT MOFFE'I, OF BRISTOL, OHIO.

MACHINE FOR MARKING WAVING PATTERNS.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, ALBERT MOFFET, of Bristol, in the county of Trumbull and State of Ohio, have invented new and useful Improvements in an Automatic Scroll- Gage for Laying Out Vinework, Oog-'Wheels &c.; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1, is a top View. Fig. 2, is a side view. Fig. 3, is an end view, and Fig. 4, is a View of the side opposite that seen in Fig. 2. v

Like letters refer to like parts in the several views.

The nature of my invention relates to an arrangement of devices, by means of which a regular vine scroll can be laid off, or be caused to vary in its depth, by changing continually and gradually the fulcrum of the arm that carries the pencil or marking point, or by changing the gears, a longer or shorter scroll can be laid out, or by making the fulcrum stationary, a regular vine, or

.cog gear can be laid out.

A, in the several figures, represents the frame of the machine. This may be made of wood, in length about fifteen inches, and in depth about two and a half inches. The wheels and other parts are in proportion.

B, in the several figures, is a spurred wheel, that is, its face is filled with sharp points. It can therefore be run along the surface of a board without slipping, and by this means, motion is given to other parts.

O, is a stop or guide (there is another not shown, at the opposite end of the machine,) that slides along the edge of the board upon which the scroll is marked.

D, is a cog wheel, placed upon the same shaft with the wheel B, seen at B, and upon which it is adjustable, so as to gear into either of the wheels E, F, G, the wheel F, being smaller than E, and G, smaller' than F. The shaft B must consequently be capable of adjustment toward the wheels E, F, Gr, which are all upon the shaft H. The bearings of the shaft B, are therefore, provided with a slot I, by means of which the shaft can be moved toward the shaft I-I.

There is an upright spur wheel J, that is put in motion by the gear E, in the side of the wheel E. The wheel J, is provided with a pin or wrist K, which moves in the slot L, in the lever M, the fulcrum of which 29,901, dated September 4, 1860.

is movable and seen at N, in the sliding bar O. The long arm of the lever is slotted, as seen in Fig. 1, so that the fulcrum N, can move nearer to, or farther from the wheel J. The sliding bar O, is moved out and in at every revolution of the wheel P, by means of the band P, and wheel Q, and connecting rod P, the wheel I), being put in motion by the band wheel Q, as shown in Fig. 1, which wheel Q is attached to the end of the shaft B, and not shown in Fig. 4. The pin of the connecting rod can be changed nearer to or farther from the center of the wheel P, as indicated by the holes a b c d, by which the distance the sliding bar is moved, is governed.

S, is an arm that carries the marking point, which is introduced into the arm S, at S.

T, is a guide for the arm S. The arm S, is attached to, and moved by a jointed finger V, which is connected to the arm M, at N.

V, is a guide which prevents the arm M from moving lengthwise.

The manner of using this machine is as follows: If a regular vine is to be marked off on the edge of the board, the stops C, are caused to slide along` the edge of the board, while the spurred wheel B, rolls along the face of the board. The wheel J, is thereby put in motion, and the arm S, is moved out and in, at right angles to the course of the machine. The pencil, or point at S, will consequently mark a scroll or vine, with regularity, provided the fulcrum remains stationary; but if the fulcrum N, is caused to move, or traverse backward and forward, by means of the revolution of the wheel P, the scroll or vine will be irregular. The undulations of the scroll, may therefore be made long or short, regular or irregular, as the operator may wish, changing the action of the machine at pleasure, by changing the wheel D, to E, F or G, and by increasing or diminishing the traverse of the sliding bar O, or making the fulcrum N, stationary.

lVhat I claim as my improvement, and desire to secure by Letters Pat-ent, ish

1. The lever M, sliding bar O, and arm S, arranged and operated in the manner and for the purpose specified.

2. The moving' fulcrum il in combination with the connecting rod P and wheel P, operated as, and for the purpose specified.

ALBERT MOFFET.
