SPECIFICATION forming part of Letters Patent No. 736,263, dated August 11, 1903.
Application filed January 19, 1903. $erial No. 13 9,621. (No model.)
clear, and exact description of the invention,
such as'will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to lubricators for heavy oils or axle-grease; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure l is a plan view of the lubricator from below. Fig. 2 is a section taken on the line on :1: in Fig. 1. Fig. 3 is a detail side view of the pawl.
A is a circular box for the lubricating material, which consists of heavy oil or thick grease which will not flow freely. The box A is provided with line screw-threads b on the exterior of its periphery.
B is a screw threaded stem which projects from the bottom of the box and which has a small outlet-hole c for the lubricant.
C is a cap which is screwed over the box A, the fine screw-threads being of sufficiently close fit to prevent the lubricating material from leaking out. The cap C forms a reservoir or chamber in which the grease is placed, and the grease is forced out ofthe hole 0 periodically by screwing the cap upon the box.
D is a ratchet-toothed wheel, which is secured on the stem B between its screw-threaded portion d and the bottom of the box A.
E-is a guide-tube which projects radially from the cap 0, with its open end beyond the edge of the cap.
F is a pawl which slides in the guide-tube E and engages with the teeth of the ratchet wheel.
G is aspring which normally holds the pawl in engagement with the ratchet-wheel. The pawl has an angle-shapedslot g in'its stem, and h is a catch on the guide. When the pawl is retracted by hand and partially revolved, the lateral part of its slot is slid over the catch, and the pawl is thereby held out of engagement with the ratchet-wheel and the cap can be removed and refilled with grease.
The pawl slides across the face of the ratchetwheel as the cap is screwed up, and the pawl prevents the cap from becoming unscrewed j and dropping off. The pawl and the ratchett may be used without screw-threads to press the grease out of the box, as shown.
What I claim is- 1. In a force-feed lubricator, the combination, with a grease-box provided with a projecting stem at its bottom having an outlethole, and atoothed wheel secured on the said stem against the bottom of the said box; of a cap screwed to the said box, a guide-tube which projects radially from the said cap with its open end below the edge of the cap, and a springpressed pawl slidable in the said guide tube and engaging with the teeth of the said wheel.
2. In a force-feed lubricator, the combination, with a grease-box provided with a projecting stem at its bottom having an outlethole, and a toothed wheel secured on the said stem against the bottom of the said box; of a cap screwed to the said box, a guide-tube which projects radially from the said cap with its open end below the edge of the cap,a,springpressed and partially-revoluble pawl slidable in the said tube and provided with an angleshaped slot g, and a stationary catch-pin h which projects inside the guide-tube and engages with the said slot.
In testimony'whereof I affix my signature in presence of two witnesses.
