Specification of Letters Eatent. Patented Nov. 2, 1915.
Application filed December 1, 1914. Serial 110. 875,042.
To all whom it may concerm. J"
Be it known that 1, DAVID CURTIS SAN- FORD, a citizen of the United States, resid- "ing at Bridgeport, in the county of Fairfield absolutely accurate, and it is with the object of providing an absolutely accurate bearing by an inexpensive method of manufacture that T have devised my novel method of making the same, which method broadly speaking, consists in-applying a surface of Babbitt metal to a sheet or strip of bronze or other suitable meta-l, then subjecting the combined metals to pressure, and finally blanking and shaping the bearing from the composite pressed sheet or strip.
The invention consists also in certain details hereinafter, fully described and set forth in the appended claims.
In the drawings forming a part of this specification, Figure 1 is a view representing a flat strip or sheet of bronze or other suitable material. Fig. 2 is a sectional view of the same sheet or strip having the surface thereof tinned. Fig. 3 is a view showing the tinned strip having the facing of Babbitt metal applied thereto. Fig. 4 is a diagrammatic side view illustrating the manner of hardening and surfacing the composite sheet or strip. Fig. 5 is an end view of same. Fig. 6 is a view of thebearing blanked and shaped from the rolled composite strip.
In the practical carrying out of my invention I employ the usual foundation of bronze or other suitable material, but instead of casting the said bronze into the usual form of bearing I employ the said bronze in the form of a flat plate, strip or sheet A. One face of this sheet or strip of bronze is tinned as shown at T, in order that the Babbitt metal will adhere to the said sheet or strip of bronze and make a thoroughly united composite whole. After the bronze sheet or strip has been tinned it is placed in a suitable jig and the Babbitt metal B poured therein, and permitted to cool.
i The combined strip or sheetis then sub jected to pressure preferably by passing between pressure rolls and by this step the combined sheet is hardened and its density is increased, the surface of the Babbitt metal is smoothed and polished, and at the same time the combined strip or sheet is rolled down to the exact gage or degree of thickness. The combined strip or sheet after being so rolled is ready for the blanking. and
shaping dies by. means of which the blank.
is punched from the strip or sheet and then shaped up into the finished bearing, and by means of the steps hereinbefore recited I provide a journal .bearingwhich 'is exceedingly accurate so far as uniformity is con cerned and the expensive steps of machining and finishing are dispensed with thereby enabling me to produce a high, grade of bearing at a very, low cost. Practical eX- perience has also demonstrated the fact that by means of the rolling process the bearing surface is rendered harder, smoother and much more durable than one which is machined.
As shown the face of the sheet A to which the Babbitt metal B is applied is formed with a series of transversely arranged grooves a into which the Babbitt metal runs when applied to the sheet and which serve to prevent the Babbitt metal from slipping in the event of the metals working apart. As shown in Fig. 1 the grooves are preferably tapered with the widest ends thereof alternately arranged on each side of the strip A.
While I have specified bronze as the f0un dation of my combined strip, and Babbitt metal as the bearing surface it will of course beunderstood that the principle of my invention applies to the equivalents or substitutes for these metals.
What I claim is: I
1. The herein described method of making journal bearings, which consists in adhesively applying a bearing surface to a foundation strip or sheet to form a composite body, applying a rolling pressure to the combined strip or sheet, and then shaping up the hearing from the combined rolled sheet or strip.
2. The herein described method of making journalbearings, which consists in tinning. a foundation strip or sheet so that the -1 hearing surface Will adhere thereto, app1y my hand this 24 day of Nevemhef; A. D.
