application and December 5, '1921. Serial No. 520,199.

To all whom it may concern: I

Be it known that I, WALTER F. HEROLD,

a citizen of the United States, and resident of Newark, in the county of Essex and State I of New Jersey, have invented certain new and useful Improvements in Furniture Shoes, of which the following is a specification. v

The invention relates .to furniture shoes 10 or slides which are adapted to be secured to the lower ends of furniture legs, or other objects. It is adapted to be applied to furniture shoes or slides which are provided with pintles which may be inserted into 16 spring sockets or other holding means within the furniture legs. It may also be applied to like devices which are not provided with pintles but are secured directly to the under surface'of the furniture as by means 20 of upwardly extending prongs.

Furniture shoes have commonly been made by casting the sliding member and securing a vertical pin or pintle theretoby inserting the lower end. of the same mto the casting while the latter is molten.

.method results in the production of a large proportion of imperfect devices for various reasons. For example, the insertion of the cold pin into the molten metal often results in formation of blow holes in the easting,-and

the strong chill resulting when the pin isinserted into the molten metal is aptfto cause the latter to draw away from the pin-when it hardens, resulting in an imperfect connection. Also it is oftentimes difiicult to make the connection in such a way that the pin or pintle will be in proper alignment when the article is completed.

' An object of the present invention is to.

40 overcome the difficulties referred to and to produce an article which willbe strong and efficient and which may be manufactured with a considerable saving in cost in comparison with the prior device. referred to above. In practicing this invention a disc is provided with a downwardlyturned edge which is pressed around or otherwise secured to the edge portion of a bearing member having a rounded lower surface 0 adapted to slide over the floor, this bearing member bearing firmly at. its upper surface against the disc so as to result in a strong andrigid construction. A pintle of any de- Such a" device sired size may readily be secured to the disc. Likewise when the deviceis to be used without 'a pintle, the disc may be provided with upwardly extending prongs or-other means for securing it to the bottom of the furniture leg.- V '1 Other objects of the invention consist in theprovision of improved details of construction and combinationsof parts, an as will appear more fully hereinafter in the following specification and be particularly pointed out in the appendedclaim.

In order that the invention, may be more clearly understood attention is hereby directed to theaccompanying drawings forming part of this application and illustrating certain embodiments of the invention. In the drawings Fig. 1 represents a furniture shoe embody-' 'ing the invention, shown in side elevation, mounted in position within a socket within a furniture leg, the socket and leg being shown in section:

Fig. 2 is an enlarged view of the furniture shoe shown in vertical section with a pintle applied thereto shown in side elevation;

Fig. 3 is a bottom plan view of the device as indicated bythe arrows 3, 3, in Fi 2, the device being partly broken away an partly shownin section; Fig. 4 is a view of a modified form of the partly shown in side elevation and partly in vertical section, and Fig. 5 is a top plan view of the device asindicated by thearrows 5, 5, in Fig. 4, the device being shown as partly broken away and partly shown in section. I

Referring to Figs. 1 to 3 of the drawings, the bearing memberjl is preferably formed ,as-a casting, although'it may, of course, be manufactured by other processes. It is providedwith a rounded lower surface 2 adapted to slide over the floor. lifember 1 may be formed of any suitable material such as cast iron when the shoe is to be used within a factory, or brass or other material when it is to be used in a residence.

The disc Sis adapted to bear a ainst the upper surface 4 of member 1 and secured thereto by means of the downwardl extending edge portion 5 of the disc whic may be secured to the edge )ortiou of member 1. Disc 3 is'preferably iormed of'sheet metal or enlargement 9 which will bear against 7 the lower surface of the disc to rivet the pin-i against the upper end of the spring socket when the device has been positioned. 'The to v v per edge about which the lower edge of .the disc is spun, or otherwise presse to secure the parts together.

The pintl 7 's ill fstr'ated asfcilredtd disc 3 by extending'the lower end portion 8 of reduced diameter of the pint-1e through a central openm in the discand upsettmg the lower end 0 the intl'e to form a'head tle to the disc, a washer- 10 preferably' being interposed between the disc and a'shoulder. 11 on the pintle. With this construction the bearing member 1 is provided with a central I recess 12 extending downwardly 1 from its upper surface which will receive t-he head 9 of the pintle after the latter has beensecured in position.

To use the device the intle '7 is-merel p i is not limited strictly-to the dctails' of coninserted within the spring socket l3qwhic is secured in place within a central opening '14 in a furniture leg 15, the enlargement 16 at the upper end of the pintle' bearing above explanation is given, of course, merely by way .of example since it is obvious that "the device may be usedin connection with spring frames or otherwise'in accordance with the usual practice with casters.

In Figures 4 and 5 the disc 3 is not provided with a, central openingtherethrough.

and has no pintle secured thereto. As shown in the drawings the disc 3? may be provided withv upwardly extending prongs 17 which may be struck from the metal and extended upwardly into the bottom of a furniture leg 15' to secure thedevice in place. The disc may be secured to the bearing member 1 in the same'manner as has been described in connection with the other form of the device o illustrated herein, the disc preferably being 545- provided with a downturned flange 5 which an e.5of. v g
