TAPPET FOR STAMP-MILLS.
SPECIFICATION forming part of Letters Patent No. 752,462, dated February 16, 1904. Application filed July 29, 1903. Serial No. 167,408. (No model.)
To aZZ whom it may concern.-
Be it known that I, EDWARD Ivns MOREY, a citizen of the United States, and a resident of Telluride, in the county of San Miguel and State of Colorado, have invented a new and Improved Tappet for Stamp-Mills, of which the following is a full, clear,'and exact description.
This invention relates to improvements in tappets for stamp-mill stems, an object being to provide a tappet so constructed as to be readily adjusted lengthwise of the stem and 1 also to be adjusted to the possible reduction of circumference due to the wear of the stem in moving in its guides, and, further, to so construct a tappet that it will be practically impossible to displace it when locked in place. I will describe atappet for stamp-mills embodying my invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 shows a portion of a stamp-mill with a tappet embodying my invention on the stem thereof. Fig. 2 is a side elevation of the tappet on an enlarged scale. Fig. 3 is a section on the line 3 3 of Fig. 4. Fig. 4. is a section on the line l4 of Fig. 3, and Figs. 5 and 6 are perspective views oflocking-gibs employed. Referring to the drawings, 5 designates a sleeve or cylinder the interior diameter of which is slightly greater than the stem 6 on which it is to be placed, the object of which will hereinafter appear. On its outer side the sleeve has longitudinally-extended ribs '7- 8 9, and the ends of these ribs connect with end flanges 10. On the inner side and in alinement with the ribs 7 8 9 the sleeve is provided with longitudinal recesses 11 12 13, the outer walls of the recesses 11 and 12 being tapered with relation to the axis of the sleeve, and
these tapers extend in opposite directions.
Movable in each recess or chamber 11 12 is a longitudinally-tapered gib 14:, the inner surface of which is conformed transversely to the stem. The ribs 7 8 are provided with transverse openings 15, into which head porserted for releasing the gib. For convenience in inserting an operating-tool a wall of said opening 17 is inclined, as indicated at 18.
Arranged between the locking-gibs '11 12 and seated in the recess 13 is astraight supplemental gib 19, which serves in coacting with said gibs 11 and 12 to center the tappet on the stem, and the stem-engaging surface of this gib 19 may be kerfed or roughened, as indicated in Fig. 6. It may be at times necessary-that is, when the stem becomes worn circumferentiallyto adjust the gib 19 inward, and therefore I provide the rib 9 at about its center with an outward opening 20, through which ashim 21, of cardboard or other suitable material, may be passed.
It will be noted that the opposite end walls of the opening 20 are arranged on an incline, so that the shim may be placed in position by putting one of its ends through said opening and sliding the same upward between the gib and wall of the recess, and then the other end may be similarlyinserted.
In securing the tappet to the stem the tapered gibs are to be forced lengthwise, which may be done by passing a Wedge-shaped tool through the opening 15 to engage with the end of the head 16. Such a wedge-shaped tool is indicated at m in Fig. 2.
When it is desired to loosen the sleeve for the purpose of adjustment, a suitable tool is to be inserted through the opening 17 to engage withthe head 16, then with a slight tap of a hammer or the like the gib will be loosened.
As before stated, the opening through the sleeve is of somewhat larger diameter than the diameter of the stem. Therefore there are no vparts bearing on said stem excepting the gibs, and thus the sleeve is not liableto wear.
' It is obvious thatatappet embodying my invention may be very quickly adjusted both lengthwise of the stem and around the same.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A tappet comprising a sleeve adapted to Each rib 7 8 at one end of its openreceive a stem or shaft, and tapered lockinggibs movable in and longitudinally of the sleeve, the tapers being in opposite directions, and the said gibs being spaced apart circumferentially of the sleeve.
2. A tappet comprising a sleeve adapted to receive a stem or shaft, a plurality of channels formed in the inner side of said sleeve, said channels being spaced apart circumferentially of the sleeve, tapered gibs in certain of said channels, the tapers being extended in opposite directions, and a straight gib in another of said channels.
3. A tappet for a stamp-mill stem, c0mprising a sleeve, longitudinal ribs on the outer surfaces of said sleeve and spaced apart, the said sleeve at its inner-side having recesses in alinement with said ribs, transverse openings in certain of said ribs, wedge-shaped gibs movable in the recesses in alinement with, the ribs having said transverse openings, the said gibs having head portions extended into the trans- Verse openings, and a straight gib in another of said recesses.
4. A tappet for a stamp-mill; stem, comprising a sleeve, longitudinal ribs on the outersurface of said sleeve, the inner side of the sleeve being provided with recesses in alinement with the ribs, each of said ribs, having an outward or lateral opening from its recess, tapered gibs movable in certain of said recesses and having outwardly-extended head portions, the tapers being extended in oppositedirections, the ribs in which said tapered gibs operate also having transverse openings into which said head portions extend, a straight gib in another of said recesses, and a shim arranged in said other recess.
5. A tappet for a stamp-mill stem, comprising a sleeve having an interior diameter slightly larger than the diameter of the stem,
In testimony whereof I have signedmy nameto this specification in the presence of two subscribing witnesses.
EDWARD IVES MOREY.
