CORNER-POST FOR BOX-LIKE STRUCTURES.
Patented June 25, 1912.
Serial No. 691,482.
To all whom it may concern:
Be it known that I, WVILLIAM ZABEL, a
citizen of the United States, residing at: Edgewood Park, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Corner-Posts for Box-Like Structures, of which the following is a specifica tion.
My invention relates to corner posts for supporting the side-pieces of box-like structures.
I will describe one form of corner post embodying my invention, and then point out the novel features thereof in claims.
In the accompanying drawings, Figure 1 is a perspective view showing one form of corner post embodying my invention. Fig. 2 is a top plan view and Fig. 3 is a side elevation of the corner post shown in Fig. 1. Figs. 4c and 5 are views showing separately two of the parts comprised in the device shown in the preceding views.
Similar reference characters refer to similar parts in each of the several views.
Referring to Figs. 1, 2 and 3, I have here shown one corner of a box-like structure of which 11 is a base, 12 is a top, and 20, 20 are two adjacent side-pieces. In Figs. 1 and 2 the top 12 has been removed to more clearly show the structure of the corner post. 10 is a stud secured in both the base and the top; as here shown this stud is provided adjacent one end with a shoulder 13 so that this end may be riveted to the base 11; the other end of the stud is drilled and tapped to accommodate a screw l t by means of which the stud may be secured to the top 12.
15 is a side-supporting member, shown separately in Fig. 4. This member is in practice preferably a stamping from a piece of rigid sheet metal. The piece is punched with several pairs of slits 16 and is then bent into substantially the shape indicated in Fig. 4, the material between the slits of each pair being bent outwardly to form bands 17 which are of such size as to accommodate the stud 10. The portions of the member 15 lying on each side of the stud serve as supports for the side-pieces 20, 20, hence theangle through which the member is bent depends upon the desired angle between the side-pieces; as here shown the device is the corner post of a square box, hence this angle is 90 degrees.
In order to hold the side-pieces 20, 20
firmly against the supporting member 15 I provide a spring member 18, which member is preferably a stamping from a flexible and springy material such as a phosphor bronze or spring steel; this member is illustrated separately in Fig. 5. This member is bent into substantially the shape shown in Fig. 5, and is provided with apertures 19, 19 of such size as to accommodate the bands 17, 17
of the supporting member 15.
To assemble the form of corner post here shown, the stud 10 is first riveted in the base 11, the spring member 18 and the supporting member 15 are then fitted together with the bands 17 projecting through the apertures 19, and the two members are then slipped 'over the stud. The side-pieces 20, 20 are then slipped into position between the two members as shown in Figs. 1 and 2 and finally the top 12 is secured to the stud by means of the screw 14.
The supporting member 15 is of material which is sufficiently rigid to maintain the side-pieces 20, 20, in proper position. The spring member 18 is preferably of material which will yield sufticiently to compensate for variations in thickness of the sidcpieces 20, 20 and which also possesses sufficient springiness to exert considerable pressure upon the side-pieces and thereby form a tight and secure structure.
A device embodying my invention is particularly adapted for use as the corner post for supporting the glass side-pieces of the box-like structures which are employed to inclose the operating parts of railway signaling and other relay devices.
Although I have shown and described only one form of corner post embodying my invention, it is understood that various changes and modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention.
Having thus described my invention, what I claim is 1. A corner post for box-like structures comprising a stud, a side-piece supporting member, means for securing said member to the stud, a spring member supported also by the stud, and side-pieces held between the two said members.
2. A corner post for box-like structures comprising a stud, a side-piece supporting member and a spring member, means embodied in said members for interlocking them and for securing them to the stud, and Is)ide-pieces held between the two said memers.
3. A corner post for box-like structures comprising a stud, a side-piece supporting member shaped to partially encircle the stud and provided with bands encircling the remainder of the stud, a spring member partially encircling the stud and located between the stud and the body of the said supporting member and having apertures to accommodate the said bands, and side-pieces held between the two said members.
A. A corner post for box-like structures comprising a stud, a side-piece supporting memberprovided with bands adapted to secure the member to the stud, a spring member located between the stud and the said supporting member and provided with apertures to accommodate the said bands, and
side-pieces held between the two said members.
5. A corner-post for box-like structures comprising a stud, a side-piece supporting member shaped to partially encircle the stud and provided with pairs of slits the material between the slits of each pair being bent outwardly to form bands which encircle the remainder of the stud, a spring member partially encircling the stud and located between the stud and the body of the supporting member and provided with apertures to accommodate the said bands, and side-pieces held between the two said members.
6. A corner post for box-like structures comprising a stud 10, a supporting member 15 provided with bands 17 to secure it to the stud, a spring member 18 provided with apertures 19 'to accommodate the bands 17, and side-pieces held between the member 15 and the member 18.
In testimony whereof I afiix my signature in presence of two witnesses.
