1? FOR TRUNKS.-
' UNITED STATES PATENT QEEICE.
WILLIAM B. GOULD, 0E MONTROSE, NEW JERSEY.
COMBINED CASTER AND CORNER-CLAMP FOR TRUNKS.
SPECIFICATION forming-part of Letters Patent No. 244,447, dated July 19, 1881.
Application filed May 19, 1881.
To all whom it may concern:
Be it known that 1, WILLIAM B. GOULD, of Montrose, in the county of Essex and State of New Jersey, have invented an Improved Corner-Olamp and Roller for Trunks, of which the following is a specification.
Figure l is a face view of the blank from which my improved corner-clampis made. Fig. 2 is a face view of said clamp with the ears turned at right angles to the body. Fig. 3 is an edge view of the blank when in the condition shown in Fig. 2. Fig. 4 is an edge view of the complete corner-clamp and roller. Fig. 5 is a perspective view of the corner-clamp without the roller, and Fig. 6 a perspective view of the corner-clamp with the roller.
This invention relates to a new form and construction of angle-irons that are used as braces or strengtheners for trunks and similar boxes, such irons being commonly known as corner-clamps. The particular kind of such corner-clamps to which my invention pertains is the kind adapted to receive a roller on which the trunk or box is supported. Heretofore such rollers have been hung in corner-irons in various ways--sometimes in braces that project from the inner angle of the iron, sometimes in cars that extend from the outer face of one of the wings of the iron. The difficulty with both of these structures was, first, in the manufacture, and, second, as to durability.
To form a corner-clam p with wings or braces that extend inward from the angle is a matter of great dificulty, and almost, as has heretofore been the construction, impossible, unless the article is cast, in which. case it is not as desirable for actual use as if made of wrought metal; yet of wrought metal it could not be made unless the ears or braces were separately soldered on. If the ears that carry the roller project outward from one of the wings of the corner-clamp, the difiiculty was, first, that the roller would frequently be at too great a distance from the trunk-bottom, and therefore liable to be broken off in use under a heavy trunk. To obviate this, more or less costly appliances to give additional strength to the roller-carrying ears have been invented and.
made the subjects of several patents; but all (No model.)
these contrivances added to the expense of the construction, and did not, in fact, always succeed in overcoming the objection as to the dis-, tance from the bottom of the trunk.
My invention consists in forming the rollercarrying cars from the blank or body of the corner-clamp in such a manner that they will project inwardthat is to say, into the angle of the corner-clamp, and so, also, that each end of the pintle or axle of the roller will rest in two ears, thus furnishing four supportingears for each roller. The two cars at each end are in contact with one another and brace each other, and thus great strength is insured without at all adding to the expense of the cornerclamp, the formation of the ears being merely obtained by a processof cutting and bending, not by adding anything to themetal of the corner-clamp.
In the accompanying drawings, the letter A I arated from the lower series of lapels, c d, by
the transverse incision g. Each of the lapels,- moreover, may, if desired, be perforated with one hole, as shown in Fig. 1, at the same time that the blank is out. In fact, the same operation of stamping or cutting'which gives external form to the blank A may also be utilized to form the set of four lapels, in mannerindicated in Fig. 1. The next partbf the opera tion is to bend said four lapels at right angles to the blank A, as in Figs.2 and 3, on the lines that join said lapels to the blank. It will be seen in Fig. 2 that when the lapels are? thus bent at right angles the lapel a is not directly above the lapel 0, but a little farther toward the inside of the blank A than c. The same remarks apply to the relative positions of the 35 lapels b and d.
Instead of forming the lapels so that a and b are nearer to each other than c and d, the
lapels c and d may be made to be nearer to each other than a and b.
The next operation is to bend the straight blank on the line of the incision g at right angles, as in Fig. 4, thereby carrying the lapel 0 face to face against and in line with the lapel a, and in like manner bringing the lapels b and d together. I thus form double braces or ears in the angle of the corner-clamp, as shown in Fig. 5, out of the material of the blank itself, and in these double braces the roller B is hung, its axle or pintle fitting into the apertures of the said braces or cars. These apertures may, if desired, be drilled through said ears after the corner-clamp has been bent into the position shown in Fig. 4, or may be stamped when the lapels for said ears are first cut out, as in Fig. 1.
I claim- 1. The sheet-metal corner-clamp A, having 20 inwardly-projecting ears on c and b 01, arranged in pairs, substantially as described.
2. The combination of the corner-clamp A, having inwardly-projecting ears a c and b d, arranged in pairs, with the roller B hung in 25 said ears, substantially as herein shown and described.
3. The method herein described of constructin g a corner-clamp with inwardly-projecting ears by cutting said ears in two pairs out of 0 the body of the corner-clamp, and then bringing them in line by first bending them on the blank, and then bending the blank itself, substantially as specified.
