v E 5 5 E5= UNiTED STATES LEvIs H. DAVIS, OF WEST oEEsrEE, PENNSYLVANIA.
IMPROVEMENT IN PlTMAN-CONNECTIONS.
Specification forming part of Letters Patent No. 158,69 0, dated January 12, 1875; application filed- January 2, 1875;
To allwhom it may concern:
Be it known that I, LEVIS H. DAVIS, of West Chester, in the county of Chester and State of Pennsylvania, have invented certain newland useful Improvements in Pitman-Ooni ectiomof which the following is a specifica- The object of this invention is to connect pitmen with the wrist-pins in such a manner bolt, H, which passes through the plate E, or
that the "boxes or bearings can be adjusted with ease and facility to compensate for wear. The invention consists chiefly in the employment-of a turn-bolt or pin having an eccentric .or cam-head which is located in an eye formed in a top extension-plate of the bearing-block or box, so that, by turning said bolt more or less, the eccentric will force or press the box against the wrist-pin or journal in order to maintainthe parts in proper relation with each other. The invention further consists in ap-' plying a handle or horizontal arm to the bolt having the eccentric head, said handle traversing a ratchet or' serrated surface on the top of a plate attached to the pitnian, so as to enable the adjusting-bolt to be retained at any desired position after the box has been properly set.
In the accompanying drawings, Figure 1 is a plan view of a pitman, having my invention applieditliereto'. Fig. 2 is a longitudinal sectional view of the same, illustrating a wristpin with a projecting head. Fig. 3 is a similar View, showing a ball-and-socket connection.
Fig. 4 is a detail view of the bearing-block and metallic holder. Fig. 5 is a detail view of the eccentric-bolt. Fig. 6 is an enlarged view of the same.
Letter Adesignates apitman, and B the wrist or crank pinto which it is connected. The pitman is provided with a slot, 0, for the reception of the wrist-pin and of a bearing block or boX,D, which is generally made of wood and metal. :In the present instance the wooden bearing-block is attached to a metallic holding-plateggfllilggyvhich has a flange, F, projecting from its underside, to serve as an end support forthe wooden block. A bolt or shank,
Gr, also projecting from the under side of the metallic plate, extends through a slot or opening', 'a, in the bearing-block, and has a nut, 12,
appliedto its threaded end for securing the block to the plate. .The' bearing-block is inserted into the slot in the pitnian so as to embrace the neck of a wrist-pin having a project- "ing head, as shown in Fig. 3, or, when a wristpin with a globular or ball head is employed, as shown in Fig. 2, the end of the bearingblock is provided with a corresponding socket, to form a ball-and-socket joint. The bearingblock is secured to the pitman by means of a an extension of the same, and is pro vided with a screw-threaded end for the reception of a fastening-nut, d. The bolt H is made or provided with an eccentric or cam-shaped head, I, which is located in a circular opening, J, in the plate E. It is generally deemed expedient to provide the-head of the bolt with a handle or horizontally-projecting arm, K, which projects over or onto a serrated, roughened, or ratchet surface, L, on the upper surface of the plate E. By the provision of these devices the bolt can be turned so as to bring more or less of the eccentric in contact with the inner side of the bolt-opening made in the plate E, thus forcing the bearing-block in an inward direction, or toward the wrist-pin for maintaining a proper joint at all times, or as the block wears away. The handle of the bolt is formed with a V -shaped or angular lower edge, so as to cause it to drop into the serrations of the surface L for retaining the boltin position after the block has been properly adjusted in relation to the wristpin. In certain instances the handle and locking surface may be dispensed with, but the eccentric head is layer of pasteboard, leather, or other suitable material, f, is then inserted in rear of the block, or between the blocks and supportingflange F, when the block is again in position to be used as in the first instance. The wooden box and metallic holder can be superseded by a block made entirely of metal, and other -1neans than those described may be resorted to for using the box so long as possible. A flange, g, formed on the bearing-block, is caused to overlap the supporting-flange F, so as to retain the elastic packing f in position.
I do not confine myself to the exact construction and arrangement of parts above described, as the eccentric or cam may be used separate from a bolt firmly attached to the same, in which instance an ordinary bolt may go through the cam, or the latter may be used without a bolt at all. The eye formed in the bearing-block, or extension of the same, for the reception of the cam, may be a long slot, or half an eye, or the cam may rest on a flat surface and bear against a stop or ledge.
It is obvious that the cam may be used for tightening boxes, or other journals than pitmen.
A washer or plate may be located on the reverse side of the'pitman for more firmly securing the hearing or box, the plate being provided with a slot for the passage of the bolts, so as to enable the adjustment of the box to take place.
. described.
Having thus described my invcntion, what or arm K, with the bearing-block ng'plt't'ean,
with its ratchet or locking-surface L, the man A, and a wrist-pin, B, substantially as 3. The adjustable bearing-block-D, having a slot, a, and flange F, in combination'with the turn-bolt H, provided with an eccentric or cam, I, pitman A, and wrist-pin B, substantially as described.
In testimony that I claim the foregoing I have hereunto set my hand.
LEVIS H. DAVIS.
