- IMPROVEMENT IN EC'CENTRIC ADJUSTMENTS.
Specification forming part of Letters Patent No. .46,27 8,"datcd February 7, 1865.
To all whom it may concern Be it known that I, J. M. STONE, of North Andover, in the county of Essex, inthe-State of Massachusetts. have invented an I tup'roved Eccentric Adjustment; and I do'hereby'dcclare that the following, taken'i'n connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.
0f said drawings, Figure 1 is an elevation ot' a shaft, showing in section thereupon two eccentrics and the means for adjusting and holding them in any desired position. Fig. 2 is an end view of said shaft with said eccentries shown as adjusted thereupon. I
Many instances occur in mechanism where it is desirable to secure two or more eccentrics on the same shaft, and to have them capable of adjustment withinthc limits of the'capaeitygiven by their construction without the employment of set-screws and keys or other parts which form projections, and are therefore liable to catchaud tear objects with which they come into contact, and which beside accumulate dirt; and are troublesome to clean.
The particular object of this invention is to reciprocate to any desired amount the rolls in such drawing-frames as are shown in the Patent No. 42,076, granted March 29, 1864, for the joint invention of Joseph Chase and myself, though the invention may be generally ustd whenever eccentrics are required to be adjusted to obtain changes in the amount of the screw thread 0 and the shoulder I the shaftis flattened on opposite sides,and each eccentric (t is bored near its periphery with a hole parallel to its axis large enough to pass the.
any desired position.
shaft on through said hole fromthe screwthread 0 to the collar b. An elongated open ing is then formed in each eccentric from the aforesaid holes, and equally on each side ofthe center ofeach eccentric, the width of said opening or slotbeing that of the thickness of the shaft where flattened. vious that the eccentrics can-be placed on the shaft, the latter passing through the holes first named in the former, and that" when on the shaft between the collarb and the'screwthread 0 the elongated opening in each eccentric can be made to encompass the flattened part ofthe shaft, so that when the shaft is rotated the eccentrics must: rotate with it. It
I will now be seen thatany amount o f eccen-t tricity of position can be given'on the shaft to the eccentrics d by moving them more or less at right angles to the axis of the shaft, and
that it-is now only needed to secure them in This is done by clamping the eccentrics between the shoulder I1 and the washer j, which is performed by screwing up the nut g. Washers or collars [L are used to keep the eccentrics any given or desired distance apart. To change the adjustment,
slat-ken the nut g, slide the eccentrics to the desired position on the shaft, and again tighten" the nut.
I claim- For the purpose of adjusting the amount of throw of any of two or more eccentrics on the same shaft, the construction and arrangement operating substantially as described. in witness whereof I havehereunto set my hand this 13th day of December, A.-D. 1864.
J. M. STONE.
