PITMAN.
Specification of Letters Patent.
' Patented July 6, 1009.
Application filed March 14, 1908. Serial No. 421,122.
To all whom it may concern:
Be it known that I, JOHN A. WrLsoN, a citizen of the United States, residing at Marple, in the county of Boxbutte and State of ebraska, have invented new and useful Improvements in Pitrnen, of which the following is a specification. r
This invention relates to pitmen, and the object of the invention is to provide a device of this character which may be readilyadjusted. to take up wear.
To these ends the invention resides in the novel construction of pitmen, hereinafter fully described and claimed.
. In the accompanying drawings, Figure 1 is a top plan view of a pitman constructed In accordance with my invention. Fig. 2 is a longitudinal sectional view upon the line 2-2 of 3. Fig. 3 is a similar view upon the line 3-3 of Fig. 1. s
. In the accompanying drawings the nu' meral ,1 designates a continuous metal strap, having its ends rounded as indicated in the figures of the drawin s. This strap 1 has its sides suitably spaced and its ends provided with reinforcing elements 2. The strap 1 has its sides provided with a plurality of openings adapted for the reception of securing elements, the purpose of which will hereinafter be more fully described. Inte osed between the sides of the strap 1 are t e itman sections 3 and 4. These sections 3 an ,4 may be constructed of any desired. material and are each provided with transverse slots 5, adapted for the recs )tion of retaining bolts 6, which are also a apted for engagement with the openings provided in the sides of the strap 1, and by which the sections 3 and 4 are secured upon the strap. The sections 3 and 4 have their ends arc-shaped to complete the circle provided by the ends of the and and the reinforcements 2, whereby a snug bearing is provided for the offsets of the cranks to which the pitman is adapted to be secured. The sections 3 andd are also pro vidcd with centrally arranged longitudinally extending slots or openings 7, adapted for the reception of retaining elements 8, by which. a top plate 9 is secured upon the secstantia tions. ,This top plate 9 serves as an effective 50 reinforcement for the sectionsand' is rvided with a centrally arranged upstan .ing portion or offset 10. This offset 10 comprises a horizontal wall provided witha suitable centrally arranged opening and outwardly inclined sides connected with the body of the plate. The adjacent ends of the sections 3 and 4 are beveled or inclined toward each other, as indicated by the numerals 11 and 1.2, and interposed between the faces 11 and 12 is an inclined or beveled spreader element 13. This spreader 13 is provided with acentTalaperture adapted forthe rece tion of a bolt or other securing-device 14, having its threaded portion extending through the opening provided in the hori-*, zontal wall of the offset 10 and adapted for the reception of a suitable nut 15, by which the spreader 13 may be drawn toward the horizontal wall of the offset 10 and the arms 3 and 4 forced toward the ends of the band 1. It will be understood that the retaining elements 6 and 8 have their nuts sufficiently loosened to allow the free movement of the sections 3 and 4.
From the above description it will be seen that I have provided a simple, chea and effective pitman which may be readi y adjusted to com ensate for'wear by the crank shafts to whi the "pitman, isattached, and one which may be readily adjusted while positioned upon the machine.
Havin thus fully described-the invention what is c aimed as new is:
In a llpitman, an endless band of a suby rectangularformation having its ends rounded, reinforcements for these ends, gitman sections .between the sides of the and and extending longitudinall from the center of the band, said sections eing-caelnQO. provided with a series of vertical and transverse elongated o enings, securing elements connecting the si( es of the band and engaging the transverse openings of the pitman sections, a top plate-provided with a central upwardly extending offset portion, headed retaining elements engaging the under face .ofthe pitman sections and extending through gaging the Wedge shaped member and the \V itnessesa the vertical slots and conneeted with the top threaded elen lent substantially as. and 01 plate, the pitman sections having their meetthe purpose setforth; ing ends arranged at angles away from each In testimonywhereof :tlfiX my signature other, a; wedge shaped member for these in presence of two witnesses. angular faces; and a threaded element enl JO H N (L; WILSON.
