BEARING-PLATE.
SPECIFICATION forming part ofV Letters Patent No. 289,597, dated December 4, 1883.
i Application filed March 5,1883. (No model.)
To all whom t may concern:
Be it known that I, JOHN BELMER ARM- STRONG, a Subj ect o f the Queen of Great Britain, residing at the city of Guelph, in the county of Wellington, in the Province of Ontario,r
Dominion of Canada, have invented certain new and useful Improvements in Bearing- Plates, of which the following is a specification.
My invention relates to a perforated metal bearing-plate having a boss or bosses provided with a cylindrical hole or holes arranged at right angles to the longitudinal plane of the plate; and the novelty consists in the peculiar construction of the same, as will be more fully hereinafter set forth, and specically pointed out in the claims.
In many machines having wooden frames flat metal plates are used -as bearings for light shafting or spindles to runrin, and in various other machines and devices where parts thereof are bolted or pivoted together similar fiat metal bearing-plates are employed to receive the friction and strain, and where these plates have a simpleperforation to receive the bolt the wearing-surface or bearing, being only the thickness of the plate, injures and wears the shaft or bolt at that point.
The object of this invention is to provide a wrought-metal plate with an extended bearing for the bolt in the form of a boss having a cylindrical hole, thereby strengthening the plate where it would otherwise be weak, and,
to construct this boss in Such a manner, by a rounded junction between the parts, that the texture of the material and its strength will not be injured, as in case of an abrupt bend..
The invention is fully illustrated in Figure 1 of the accompanying "drawings, which represents a central longitudinal section of my improved plate; but for convenience I illustrate the means for punching the plate in part section, the punch proper being in elevation. Fig. 2 shows a section illustrating the plate applied as a shaft-bearing, and Fig. 3 (also a section) shows my invention applied as a bearing-plate where two wooden pieces are pivoted to each other.
- It will be observed that not only does the cylindrical boss of my improved plate afford an extended bearing for the bolt, but the boss itself forms a securing or steadying means between the plate and the part to which it is secured.
Referring to the drawings, A represents the body of the metal plate, having a cylindrical sleeve, B, formed at right angles to the longitudinal plane of the body A by punching, and having at each side of the junction between the body and boss, when completed, the rounded or curved corners a b, as shown.
C represents the body of the punch; C', a cylindrical portion; c, a conical point, and c' a rounded portion betweenthe partsO and C. This punch is used in connection with a hol-` low block, D, having a rounded inner edge, d. These means, however, form no part of this application.
In Fig. 2, D represents a wooden framing provided with mymetal plates A A, in which runs the shaft E, carrying the pulley F.
In Fig. 3,G H represent two wooden pieces-- as, for instance, the cross-bar of a pair of thills and a whiffletree-provided with the bearing-plates A and pivotally lsecured together by the bolt I.
I am aware that conical sleeves or bosses have been before known in similar relation with a plate; but for the purposes herein set forth the bosses must have a cylindrical aperture, and the conical aperture would not serve to extend the bolt-bearing.
I am also aware that cast-metal plates have been provided with bosses having cylindrical holes, and I therefore disclaim this feature, broadly.
What I claim as new is- 1. A wrought -metal plate having a boss provided with a cylindrical hole, and punched from the material at right angles to the longitudinal plane of the plate, the said boss serving to extend the bearing for a shaft or bolt to strengthen the plate at the point'of perforation and to afford a holding means, as set forth. A
2. The Ywrought metal plate herein described, consisting ofthe body A, and the cylindrical sleeve B, formed at right angles to the longitudinal plane of the said body, and having rounded corners a b at the junction of thev sleeve and body, as and for the purposes set forth.
J. E. ARMSTRONG.
