SPRING-FRAME FOR BEDS.

Specification of Letters Patent.

Patented Apr. 28, 1914.

To all whom it may concern Be it known that I, FRANoIs EUGENE SLOAN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Lnprovements Spring-Frames for Beds, of which the following is a specification.

This invention relates to improvements in mattress spring frames for beds and has particular reference to an improved means for securely connecting the angle bars of the wire spring mattress to the ends of the stretcher tubes whereby to prevent the bars from turning with respect to the tubes and to hold said bars at right angles to the tubes.

The invention is illustrated in the accompanying drawing wherein,

Figure 1, shows the end of one of the tubular stretcher bars and in connection between the same and the angle bar at the end of the woven wire mattress. Fig. 2, is an end ele- Vation of the same, and Fig. 3, shows a perspective view of the bracket plate that is 1nterposed between the tube and angle bar.

In the drawing the numeral, 1, designates one of the side stretcher tubes of which there are two in a mattress structure as is well known in the art to which this invention relates. In the present instance it is deemed sufficient to show the end of one tube only as the two ends of both tubes are constructed in and connected precisely the same manner.

The end of tube 1, is provided with perforations such as shown at, 2, and the perforations, of which there are two in number are located in diametrically opposite sides of said tube. A reinforcing plug, 3, is preferably inserted in the end of the tube and said plug has a passage or opening, 1, extending diametrically therethrough which registers with the perforations, 2, in the opposite sides of the tube, 1.

On top of the tube I provide an improved saddle plate, 5, which has a perforation, 6, extending therethrough. This saddle plate has incisions, 7, in its opposite side edges that extend inwardly from the edges and between the incisions and one end, said plate has down-turned side flanges, 8, while between the said incisions and the opposite end said plate has up-turned side flanges, 9. It will thus be understood that the incision in the opposite side edges of the saddle plate serve to separate the metal at said edges in order that the portion of metal at one side of each incision may be turned down while that portion at the opposite side of each incision may be turned up, as clearly seen in Fig. 3. By this means the up and down-turned flanges at the opposite side of each incision may be formed with no waste of metal in producing the saddle plate.

It will be noted by reference to Fig. 2, that the flanges, 9,-at one end of the saddle plate are farther apart than are the flanges, 8, at the opposite end and that the latter flanges, 8, depend just enough with respect to the diameter of the tube, 1, to allow the central under side of the saddle plate proper to rest on the tube while the lower horizon tal edges, 10, of the said depending flanges, 8, will both contact with the circumference of the tube at opposite sides.

An angle-bar has its lower horizontal flange part, 11, seated on the flat surface of the saddle plate and the edge, 12, of said flange part contacts with the vertical faces, 13, of the up-turned flanges, 9, of said saddle plate thereby the said flanges, 9, will form a stop for said angle bar so that when a bolt, 14, is passed through a perforation (not shown) in the angle bar flange, 11, then through the perforation, 6, in the saddle plate and finally through the tube and plug therein, a nut, 15, will hold the said arts together and prevent movement of any ind. It is to be particularly noted that by the contact of the edges, 10, of the down-turned flanges at points below and on opposite sides of the center of the top of the tube, 1, the saddle plate will be held against swiveling or turning on the tube when the bolt, 1 1, is locked by the nut, 15.

The wire fabric forming the spring, 19, for the mattress is secured to the vertical flange, 16, of the angle bar,a bar, 17, being employed to serve as a clamp to this end and suitable bolts, 18, serving to secure the bars and the wire of the spring to the angle bar.

The plug, 8, in the tube will prevent the same from collapsing when the bolt, 14:, is drawn down by the nut and the depending flanges, 8, by seating on the circumference of the tube prevent the saddle plate from swiveling or turning on the bolt as a pivot if the frame is accidentally hit or dropped on one corner.

Having thus described my invention what I claim and desire to secure by Letters Patent is,-

1. A saddle for the stretcher tubes and angle bars of wire spring mattress frames comprising a plate having a fiat portion With a perforation therein said platehavingside flanges which turn down from the flat surfaceand whoselower edges seat ;on. the stretcher tube and said plate also having an upturned flange which flange is entirely sep arate and independent of the down-turned 'flanges,said rip-turned flange forming a stop for the angle bar ofthe mattress frame.

2 A saddle for stretcher tubes and angle bars of .wire spring: mattress frames co1nprising a flat plate portionlon which the angle bar seats said flat portion having a perforation extending therethrough and at opposite sides of saidflatplate portionthe saddle being provided with crosswise-extending edge incisions which extend inwardly and toward each other, and said plate betweenlthe edge incisions, and one end having flanges which turn up from'the top surface of thefiatplate portion, and between said incisions and the opposite end, said plate being provided with flanges Which. turn down from the top surface of the fiat plate portion said -up-turned and down-turned flanges being entirely separate and independent of each other.
