The port Lubricators, of which the iollowmgr is a speci-n c is adapted tc first connect the inlet-conduit D with the pump, and then to connect the accompanying drawings. pump with the dischargeassage E to the e invention relates to an improved sight-'feed conduit, while t eport bis adaptforce-feed lubricator; land it consists in the ed to first connect the section F ofthe sightconstruction of such a device in which the feed conduit with t e pump and then con oil is talen'irom a reservoir to a pump, disn v nectthe pmnp with the dischargcconduit DQ charged by the pump through a sightJeed-vV The' shaft il at one end is provided'with conduit, and then taken by the saine pump the worni-wheel i, which meshes with the om the sight-'feed conduit and delivered worin l on thc driven shaft K, which is driven out through the dischargejpassage to the i from any suitable source of' power. A series point to belubricated. l oi these pumps are arranged side b side, as e invention particularly consists in a I shown in Fig. i, and, as describe have a series ofv such pumps and in the construction common valveshaft for all the pum s. of the device Awhereby it is adapted for such series arrangement, and, further, in the concation, reference being had therein to the having the pins o r roller-wrists c and the construction of such series of pumps with a necting-rod M engaging the camways ofthe common separately-ported valve-shaft for i cams, and connected to and o erating the all the pumps,- and,further, in the construe crosshead N.- Passing throug the crosstion, arrangement, and combination ci the head are the pistons B', and each piston is various parts, as more fully hereinafter deprovided with the screw-threaded portion al scribed, and particularly pointed out in the engaging a nut e. Below the cross-heads claims. are the pins or shoulders L. The stroke of In the drawings, Figure i is a section the piston maybe adjusted by through the reservoir, showing three pumps i iston and adjusting the distance between and partly in section, and also the nut c and the shoulder or pin h.

he valve-casing preferably has the provided with suitable packing slit Z, m, and the clamping-holt 0 with the s ring p for effecting i a resilient `clamping cip the valve-casing against the rotary valve-shaft in order tovat all-times maintain a tight joint.

At the hase of each cylinder, in case the cylinder itself is not large enough to span the two ports a b, I make the lateral enlargement a', so that there will be sufficient width of opening to thus span these two ports and `bring,the res` ective conduits into communication with t e cylinder of each pump.

The parts being thus constructed their operation is as follows: The shaft K being rotated it will impart rotation to the valve shaft H, and it, through the cam L, will reciprocate the cross-head N, and according to the adjustment of the nuts e will give the desired reciprocation to the pistons B', accordis a reservoir, and in this case .l have shown the pumps arranged t pum consisting of a cylinder i3, B', the valve-casing C below thepuinn preierably formed integral therewith and eving the inlet-conduit D and dischargemonduit D. O positethc inlet-conduit is the conduit E, which extends rst laterally, then upwardly, then forwardly to the nozzle E,.and then downwardly, andreturns to the valve-casing in the section Fthereof, Fig. 3. Opposite the nozzle E is a sight-feed glass G, through which the amount of oil passing through this sight-feed passage can be observed. It will be noticed that this sight-feed conduit extends from the Valve-casing at the face of the' un, each ne piston nection being in line with the discharge-con- .'Qatented Jan. 15,1907.
