PARLOR GAME. No. 355,947.

/g Patented Jan. 11,1887.



SPECIFICATION forming part of Letters Patent No. 355,946. dated January 11l 1887.

u Application filed September 2B, 1886. Serial No. 214,752. (No model.)

To @ZZ whom it may concern:

Be it known that I, ADoLrH A. OEs'rREI- CHER, a citizen of the United States, residing at La Grange, in the county of Fayette and State of Texas,have inventedcertain new and usefulImproveniente in Corner-Protectors for Trunks, Ste.; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and Y use the same.

My invention relates to protectors for the corners of trunks, packing-boxes, and like receptacles; and it has for its object to provide an elastic protector which will be simple in construction, easily applied, which will not be liable to distortion by rough handling of the article on which it is placed', and with whose attaching-plate a socket for t-he caster may be integrally formed.

The invention will be first fully described in connection with the accompanying drawings, and then clearly defined in the claims,

Figure 1 of the drawings is a perspective View of a trunk with my invention applied. Fig. 2 is a perspective view of a protector detached and inverted. Fig. 3isasectional view of the same, taken on thelinexx, Fig. 2. Figs. 4, 5, and 6 are perspective details illustrating, respectively, the rubber buffer, the collar, and the attaching-plate. Fig. 7 is a view in perspective of the protector in a position different from that shown in Fig. 2. Fig. 8 is a perspective view of a combined attachingplate and easter-socket. Fig. 9 is a side elevation of a caster suitable for use with my combined attaching-plate and caster-socket.

represents what I term the buffer.77

Referring to the accompanying drawings, A This is formed of rubber, and preferably of the shape shown in the drawings-that is tosay,rounded on its exterior, and with an angular depression in its'under side to conform to and fit over the corner of the trunk. In it is formed an opening, a, through which to insert a metallic washer, w, to be seated in an annular groove, a', as seen in Fig. 3. It is also formed with a peripheral recess, a2, at its base, for the reception of a metalliccollar, which will be presently described.

B represents the collar, which may be cast or otherwise formed of any suitable metal.

The collar, it will be seen, has .perforations formed in it, through lwhich by rivets it is to be secured to the rubber buffer, audit is also formed with perforated lips b, as seen in Figs. 5 and 7 y @represents the att aching-plate, cast, struck up, or otherwise formed of any suitable metal. As will be seen in Fig. 6,this plate is so shaped as to form' three Wings, c, which stand at such relative angles to each other as to fit snugly over the corner of the trunk. Atthe point where these 'Wings join the plate is flattened, as seen at c in Figs. 3, 6, and 8, in order to avoid the danger of fracture to which the plate would be liable if the wings came together at a sharp angle. This flattened `surface of the plate also serves as a base for an outwardlyprojecting pin, p, cast integrally with the plate or secured thereto. This pin is designed to pass into the buffer through a-perforation, as, Fig. 3, therein, its outer end resting loosely in washer w. The attaching-plate is perforated for securing the collar thereto, and also for attachment to the trunk, as shown.

In putting the protector together the washer is first inserted in opening a in the buffer,and pushed down to its seat in the annular groove. The collar is next placed on the buffer. Next the attaching-plate is putin place, with its pin resting loosely at its outer end in the washer, as before stated. Then the collar, buffer, and attaching plate are riveted together, and, nally, the attaching-plate is secured to the corner ofthe trunk.

The purpose of the pin on the attaching-plate is to support the elastic buffer,and to prevent it from being wrenched out of shape and place by hard usage. Vhen the buffer is compressed,

the pin will slide loosely within the washer; but

the buffer will'not be compressed enough to permit the pinto project entirely through it. The

washer, as will be apparent, serves as a guide for the pin, and prevents it from digging into the rubber. By recessing the bu'er, so that the outersurface of the collar may lie about flush with the outer surface of the former, a neater appearance is presented, and also the collar is to a considerable extent protected from breakage.

In Figs. 1 and 8 I have illustrated how a socket for a caster may be formed integrally' with the attaching-plate of the protector With= out in the least departing from the spirit of my invention. This is done by simplylengthening one of the wings of the plate and casting therewith or soldering thereto the socket D, that part of the Wing which overlies the socket being made concave and perforated, as at d, for the reception of the stem of the caster, a form of caster suitable to this socket being shown in Fig. 9 and lettered E. In putting the casterin the socket,slem e is passed through perforation d in the plate and riveted down, the riveted head thus formed being accommodated in the concavity above mentioned. The

shoulder e will then bear against the underside of the plate, the barrel e2 will lit loosely in the socket, and the shoulder es will bear against the lower edge ofthe socket. This oonstruetion affords a Very strong and durable caster.

I am aware that it is not new, broadly, to

combine acaster with a trunk-corner protector; but I am not aware that a socket for the reception of the stem of a caster has ever, prior to my invention, been formed on the attaching-plate of the protector.

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Acorner-protector for trunks and like receptacles,consisting of an elastic buffer, a collar surrounding a portion of said buffer, and a perforated attaching-plate to which the coltherein, and a. collar surrounding a portion ofl said buffer and secured thereto, of an attaching-plate provided with an outwardly-extend ing pin for entering the perforation in the buffer and 'engaging with the washer, substantially as described, and for the purpose setforth.

3. The combination, of an elastic buffer, a collar surrounding a portion of said buffer, a perforated attaching-plate provided with a castersoeket, to which plate the ccillar and. buffer are attached, and a caster, substantially tially as described.

4. The combination, with a perforated elastic buffer, a metallic washer seated in an annular groove therein, and a collar surrounding a portion of said buffer and secured thereto, of an attaching-plate provided'with a castersocket and also with an outwardly-extending pin for entering the perforation in the buffer and engaging with the washer, and a caster, substantially as described, and for the purposes set forth.

In testimony whereof I afx my signature in presence of two witnesses.
