ALBERT B. DISS, OF NEWARK, NEW JERSEY, ASSIGNOR TO THE BASSICK COMPANY, OF

BRIDG-EPORT, CONNECTICUT, A CORPORATION OF CONNECTICUT.

CASTER.

Application filed March 31, 1919.

To all whom it may concern:

Be it known that I, ALBERT B. DISS, a citizen of the United States, residin at the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Casters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to certain new and useful improvements in a base bearing caster, and the principal object is to improve the mounting and construction of the pintlereceiving socket or sleeve for simplifying the construction along economical lines without sacrificing the advantages of the type of caster.

The invention, in one phase, consists in rolling the socket sleeve from a flat section of sheet metal which has been previously slit at several points inwardly from the edges and also along one edge whereby in its completed form the tubular body will have a split portion intermediate its ends to define a resilient central section, and one end will be divided into a plurality of clenching tongues or members for embracing the caster-retaining spring frame.

The invention further consists in other structural features hereinafter described and claimed, reference being had to the accompanying drawing wherein Figure 1 is a vertical section through the improved caster mounting as applied to a tubular leg;

Fig. 2 is a top plan view of the caster mounting per 96;

Fig. 3 is a'plan of the blank from which the spindle socket is formed;

Fig. 1 is an elevation of the spindle socket after being rolled but prior to attachment in position; and

Fig; 5 is a transverse section on line 55 of Fig. 1 with the tubular leg being omitted.

The caster wheel 1 is journaled within the horn 2 from the top of which rises the pintle 3 having an enlarged head or shoulder 4 for holding the pintle within the socket or sleeve 5 after having first been sprung past a pair of opposing projections 6 pressed in from said socket.

The socket is rolled into tubular form.- from a flat rectangular sheet of metal. 7

which has its upper edge divided by a series of slits 8 into a plurality of clamping tongues 9. The central portion of the sheet is divided by slits 10 which may be distinct and separate from slits 8 although they are here depicted as continuations of certain thereof. The projections 6 are also preferably formed while the sheet metal is in a fiat state. The sheet is then rolledinto a tube and its lower end portion is peripherally crimped or swaged to form an outstanding flange or shoulder 11.

The base plate 12 is provided with a centrail opening to receive the lower end of the socket the protruding end of which is crimped to form a second shoulder or flange 13 for firmly clamping the base against the shoulder 11. The base plate is formed with a circular swell or ridge 14 to function as a glider when the caster wheel and spindle are removed, and also an upstanding annular wall or flange 15 to embrace the lower end of the tubular furniture leg 16.

The spring frame 17 substantially of U- design has its flat top 18 provided with a central opening 19 through which certain of the clamping tongues 9 are passed and bent down over said flat top while the remaining tongues are bent out at right angles beneath said fiat top 18 to constitute an underlying support therefor. In the drawings four oppositely disposed tongues 9 are passed through the opening 19 whereas the remaining two tongues are arranged to un derlie and support the top plate.

This simple securing means for the spring frame facilitates the construction and semblage of the caster and obviates the necessity of employing additional fasteners as rivets between the socket and spring frame. The construction is also rendered very economical as well as efficient by this improved connection.

In inserting the spindle into the socket the head 1 is forced between the projections 6 which yield more readily by reason of the slits 10 that divide the central portion of the socket into radially expansible sections.

The clamping tongues 9 firmly grip the spring frame without the aid of other means and the base plate in turn is rigidly fixed to the lower end of the tubular socket and retains the shape of the latter from spreading. This construction, while very economical, is especially adapted for casters of the base bearing type and functions very efliciently in the embodiment depicted in the drawings.

What is claimed isl A caster comprising a pint-lo provided on its upper end with a head enlargement, a base formed with a central opening, a socket sleeve having its lower end disposed within the opening and crimped above and below the base to form base-engaging flanges, the upper end of the sleeve being divided by short slits into a plurality of clamping tongues certain of which are bent outwardly, a spring frame seating on the outbent tongues and formed with an opening through which the remaining tongues are passed and bent back upon the frame to clamp the latter between said tongues, said sleeve being longitudinally slitted intermediate its ends to increase its resiliency and inward projections on said intermediate slitted portion of the sleeve to engage beneath the pintle head.

plane including the others, and an inverted U-spring frame having an opening through which certain of said tongues extend for clamping the frame onto the other tongues.

3. A caster comprising a base member, a tubular socket sleeve rolled from a sheet of metal and secured thereto, the upper end portion of said sleeve being slit to define two longitudinally spaced sets of outwardly bent tongues, and means clamped between the sets of tongues for securing the caster in position on a tubular post.

In testimony whereof I aiiix my signature.
