UNITED PATENT OFFICE.
SALEM T. LAMB, OF NEW ALBANY, INDIANA.
lMPROVED PITlVlAN-JOINT FOR HARVESTERS.
Specication forming part of Letters Patent No. 95,359, dated September 28, 1869.
To all whom it may concern Be it known that I, S. T. LAMB, of New Albany, in the county of Floyd and State of Indiana, have invented a new and useful Im provement in PitmanAJoints for Harvestcrs; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view of myinvention. Fig. 2 is a plan view of same. 'Fig 3 is a side elevation of the same. Fig. 4 is a vertical longitudinal section of the same. Fig. 5 is an elevation of end of pitman, Fig. 6, side elevation of sleeve; Fig. 7, end View of sleeve; Fig. 8, cross-section through nut, sleeve, and pitman; Fig. 9, back oi' pitmany Fig. l0, back and end views of sleeve; Fig. 11, plan View of nut; Fig. 12, bottom view of nut.
This invention relates to that class of pitman-joints which are made flexible in lateral directions; and it relates to a pitman-joint constructed in the form of a hook and eye, and provided with devices for taking up lost motion and compensating for Wear.
That others may understand the construction and operation of' this invention, I will particularly describe it.
A is the cutter-bar, having the cutter-sections B B secured thereto `in the usual inanner. The heel of the cutter-bar is forged with a projection, G, the upper surface of which runs under the guide-liange attached to the inner shoe, to prevent the cutter bar from being raised from its seat during its reciprocations. At the rear of the projection C is the eye D, through which the hook at the end of the pitman is inserted. The eye D is formed within the segment of the cylindrical ring E, which may be forged with the heel of the cutter-bar, or may be made separately and afterward attached. -At the end of the pitman F the hook G is formed by bending the end of the same upon itself, in the manner shown in Fig. 5. The hook G must be circular in cross-section, and should be of size sufcient to snugly ll the eye D. The outer side of the hook may be dressed off, as shown in the figures, so as to be flush with rear edge of the cutter-bar. A screw-thread, H, is cut upon the pitman-rod, just in advance of the hook, and a screw-nut, I, is fitted thereon. The lower part of said nut is formed into a sleeve, which incloses the upper end of the pressure-block J, which is bored to fit snugly over the screwthread H, as shown in Fig. 4.
The pressure-block has at its upper end, next to the nut I, an annular ratchet, K, the teeth of which engage with the end of the springpawl L, which is coiled and secured within the sleeve ofthe nut, as shown in Figs. 8 and 12. This prevents the nut from retrograding, except when the spring has beeny disengaged from the teeth ofthe ratchetK. At the lower end of the block J is a cross-head, M, 'which is notched at its outer end to receive the end of the hook G, as shown in Figs. 1 and 7. Thus the interval betweenthetwo parts of the hook G is lilled up, and the block J eiectnally prevented from turning on the pitmanrod.
The surface of the cross-head M toward the hook G is made concave, as shown at N, Figs. 4 and 7, so as to increase the bearingsurface against that portion of the eye which is brought in contact therewith.
The spring L is provided with a little lip or projection, O, on one side, which passes through. a hole in the flange of the nut, so as to be conveniently within reach to .withdraw the spring when it is desired to remove the nut I, so that the cross M may be withdrawn and the parts of the joint separated.
By these means a joint is formed by a simple hook and eye, which may from time to time be tightened up to compensate for wear, or to take up lost motion from any cause.
Having described my invention, what I claim as new is- 1. Forming a pitman-joint by means of the eye D E and hook G, in connection with a pressure-block, J M, or its equivalent, to compensate for wear and take up lost motion, as
described.
2. The nut [,'constructed with a sleeve and spring-pawl, L, substantially as described, in combination with the ratchet K on the end of the pressure-block J, as and for the purpose set forth.
