CONNECTlNG-ROD.

SPECIFICATION vforming part of Letters Patent No. 239,419, dated March 29, 1881.

Application filled February 16, 1881.

To atl whom fit may concem Be it known that I, JAcoB J. ANTHONY, ot' Sharon Springs, in the county of Schoharie andState of New York, have invented a new and Improved Connecting-Rod, of which the following is afull, clear, and exact description.

The object of this invention is to'provide a lubricating connecting-rod for cranks, crankpins, slides, or other parts of mechanism where connecting-rods are used. l

The invention consists of a connecting-rod composed of a straightr tube forming an oilchamber, having a journal-box secured on each end and communicating interiorly therewith, the caps of said journal-boxes being heldin position by straps extending parallel with said tube, and on either side thereof. The said tube is designed as a reservoir to contain the lubricating-oil for the journal-boxes, or for the slides, cranks, Snc., and the said boxes are formed with concave ends for holding suitable packing to prevent the escape of the lubricant.

Figure l is a plan of the connecting-rod, partly in section, on line m fr, Fig.2. Fig. 2 is a side elevation of the same, partlyin section, on line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a straight tube designed for an oil-reservoir, having secured on each end, by screw-threads or otherwise, a journal-box, B, the lower halves of said boxes B being provided on the outside with central hollow bosses, B,communicatin g with the interior of said boxes, in which the ends of the said tube A are secured at right angles to the axes of the said boxes B.

C C represent thejournal-box caps, the cap C bein g provided with lateral perforated lugs a, through which pass the ends of the straps or clips D,tbat hold said caps GC in position, said straps or clips D D being bent around the cap C in grooves b, near the ends thereof, and extended parallel with the tube A and on either side thereof through the lugs t of the cap C, and being secured and drawn tight by nuts c on their ends. Grooves bare also formed on boxes B and cap C for the clips D to fit into, so that said clips D may hold more securely in place, and all lateral movement of said caps (No model.)

G C be thereby prevented. Hence it will be seen that said clips D D form a perfect stayin all directions, holding the parts ofthe journalboxes so firmly together that they will not move upon each other'and cut their journals or disarrange their interior packing. Thejournal-boxes B G are designed to be made longer than is usual, as it is found that long journalboxes wear more evenly, cut the journals less, cause less friction, and consequently lastlonger. The linings E of these boxes B C are countersunk in each end, as shown at d, sufficiently tovreceive a suitable packing, f, around the journals F, and suitable packing, g, is also placed between the two parts B C, to prevent escape of oil. Communication between the tube A and .the interior of the boxes E C is made by means of passages h.

Directly back of the bosses B small transverse holes i are drilled through the tube A and pins k inserted therein, for the purpose of holding in position the fibrous packing (represented atl) thatis inserted in each end of said tube A, to serve as a strainer forthe lubricating-oil within said tube A, which oil is rcpresented at l. This fibrous packing Z prevents the impurities in the said oil Z from entering the journal-boxes B O, while permitting said oil to pass through it. In the top of said bosses B it is designed to form holes m, communicating with the interior of the tube A, an din these holes m to insert screws m', that can be turned down to force the fibrous packing l through said holes m into said tube A, and said hole or holes on serve also for the introduction of oil, Z', into said tube A.

In that end ofthe device which is designed vto serve as the head when using it vertically an oil-passage, n, is fdr-med, which is shown in the drawings as closed by a screw, n. When the connecting-rod is used vertically this screw n is to be removed and an oil-cup to be inserted in its place, through Which the box to which it is attached may belubricated.

When designing to apply this connecting-rod to cross-heads or to slides, as indicated at o, I drill a hole, p, through each side of the lower boss, B', and insert therein small tubes q,that communicate with the interior of the tube A, and on the outer ends of these tubes q, I attach IOC tubes r, through ivhich the said slides o will be lubricated from rthe said tube A.

On the outer screw-threaded ends of the journals F are nuts F that are designed to be turned down, when required,^to tighten the packing f more eiiectually about the journals F. Said nuts F may be looked in place by pins s passing through them and the journals F, or they may be secured from turning loose by any other suitable device.

In the operation of this improved connectin g-rod the strain of the thrust is borne by the tube A, and that of the pull by the clips D D. The double clips D D impart great strength and durability to the said connecting-rod and hold the boxes BG firmly in position, the nuts c being tightened as required.

The` device is cheap of construction, and lighter and stiffer than any other connectingrods of equal Weight.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

l. A connecting-rod for machinery, con-l F, substantially as herein shown and de- 35 scribed, said nuts being designed for tightening the packing in said boxes about the journal, as set forth.

3. rlhe combination, with the connecting-rod A D, of the lateral tubes q, substantially as 4o herein shown and described, whereby oil may be conducted from said rod, as set forth.
