UNITED- STATES PATENT OFFICE.

AIME VU ILLIER, OF BROOKLYN, NElV YORK.

ECCENTRIC.

SPECIFICATION forming part of Letters Patent No. 447,386, dated March 3, 1891. Application filed November 29, 1890. Serial No. 373,056. (No model.)

T 0 all whom it may concern.-

Be itknown that I, AIME VUILLIER,of Brooklyn, in the county Kings and State of New York, have invented certain new and useful Improvements in Eccentrics; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to theaccompanying draw.- ings, and to the letters of reference marked thereon, which form part of this specification.-

M y invention relates to an improvementin eccentrics in which the degree of eccentricity can be enlarged or diminished at will. The object of my invention is to provide an eccentric in which the degree of eccentricity, and consequently thelateral motion imparted by the eccentric, can be increased or diminished at will. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure l is a perspective view of the eccentric as it appears removed from the shaft. Fig. 2 is a perspective view of the pin or lug of the eccentric, showing the same affixed to a rotating shaft. Fig. 3 is an end view of the eccentric on the shaft, showing the eccentric set at a point where the degree of eccentricity is at the minimum. Fig. 4 is an end View of the eccentric on the shaft, showing the eccentric set to the maximum degree of eccentricity.

Similar letters refer to similar throughout the several views.

The letter A represents a sleeve having an eccentrically-located bore; the letter B, an eccentric pin or lug extending from the shaft 0 of the eccentric. The lettersE E represent the sockets in the bore of eccentric sleeve A, and the letters ff the cogs in the eccentric pin or lug B. The sleeve A and lug B are provided with suitable means for holding the sleeve in the desired relative position on the lug, such as intermeshing cogs and sockets, as hereinafter set forth.

The sockets E E and the cogs ff are so constructed as to fit securely into each other and hold the eccentric sleeve A firmly on the eccentric pin or log B, and are made so that parts any of the cogsff will fit into any of the sockets c a, so that the eccentric sleeve A may be adjusted at any position on the eccentric pin or lug B.

For the purpose of modifying the degree of eccentricity the eccentric sleeve A can be placed on the eccentric pin or log B in a position such as is shown in Fig. 3 of the accompanying drawings, when the degree of eccentricity is the least, or in the position shown in Fig.4, when the maximum degree of eccentricity is produced, or in any otherposition between these two positions and the degree of eccentricity, and consequently the lateral motion imparted by the eccentric can be modified as desired. The number of the cogs ff and the sockets e e can be modified in 0011- Y structing the eccentric sleeve and pin according to the number of adjustments which may be desired.

In the accompanying drawings the eccentric is represented as a circle; but an eccentric arm or any other shape may be adopted.

The eccentric pin or lug B in the accompanying drawings is located on the rotary shaft 0; but it may be located either on the shaft itself or at any point on a shaft, arm, or disk connected with the rotary shaft 0.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the rotary shaft having an eccentric pin or lug, of a sleeve provided with an eccentrically-located bore, said sleeve and pin or lug being provided with corresponding cogs and sockets, substantially as described.

2. The combination, with a shaft having an eccentric lug or pin rotating with the shaft and provided with cogs and sockets, of a sleeve having an eccentricallylocated bore adapted to receive the eccentric lug, and be ing provided with cogs and sockets to engage the cogs and sockets of the lug, whereby the sleeve can be adjusted and its degree of eccentricity changed at will, substantially as described.

3. The herein-described eccentric, consisting of the eccentric-pin carried by a shaft and the sleeve on said pin provided with an eccentric bore, said sleeve being capable of 1 In testimony that I claim the foregoing as adjustment on the pin to vary the degree of my own I aflix my signature in presence of eccentricity, said pin and sleeve being protwo witnesses.

vided with means, substantially as described, AIME VUILLIER. 5 for relatively holding or locking said parts Witnesses:
