Application m June s, 1925. Serial No. 35,579.

To all who/ii it may concern:

Be it known that I, SHERMAN. A IIA- 'llIOllXli, a citizen ofthe .United States of America, residing at VVaukegan, in the county of Lake and State of Illinois, have ill-vented a new and'useful Improven'ient'in Floor Fastenings for Stoolsand the like, of which the following is a specification.

This invention relates to fastening means whereby the hollow base of. a lunch room or like stool is fixedly secured to the floor in a substantial yet readily detachable manner, and has for its object To provide a structuralformation and association of parts whereby "the, stool or.like base is firmly clamped and held on the floor in a strong and effective manner, and with which the attaching means'is wholly concealed from sight, and is capable of ready manipulation when a detachment of the stool is desired, all as will hereinafter more fully appear.

In the accompanying dra wing Fig. 1 is a sectional plan view on line 1-1. Fig. 2, of a stool base having the invention applied.

Fig. 2 is a vertical sectional elevation on line 2-2 Fig. 1.

Like reference numerals indicate like parts in both views. 1

In the present construction, the base 1 of the stool or like pedestal is of a shell form, open at its bottom and preferably of the triangular form-shown. On the inner walls of said base 1, a plurality of fixed and laterally extending lugs 2 preferably three in number, are arranged in circularly spaced relation and formed with inclined faces on their top surfaces as shown. The base 1 carries in addition a fixed and centrally depending circular neck or collar 3, for positioning engagement with the inner ends of a series of radially arranged ribs of the stationary floor plate or member now to be described.

The floor plate or member 4 above referred to, is of a less size than the cavity of the stool base 1 and is preferably of an outline complementary to that of said cavity in order that the stool base as it covers and encloses the floor plate, is capable of a limited turning movement independent of the fioor plate in an assembly operation of the parts as hereinafter set forth in detail.

combination of a pedestal base bottom shell form having a plurality of lat- The floor plate 1 is fixedly secured by screws 5 or other fastening means to the ioor of the room, and on its upper surface carriesa plurality of radial ribs 6 the inner ends of which have spaced relation one to the other so as to form bearings or abut ments for the central circular neck or collar 3 of the stool base '1 to maintain the same in position in an independent turning movement ,of" said base in relation to said floor plate.

On its under side the floor plate 4: is formed with a plurality of inclined faces or planes 7 in circular spaced relation one to the other and complementary to the inclined lugs 2 of the stool base 1. The inclined faces or planesT and the inclined lugs 2 are adapted for interlockingengagement, when in an assembly of parts, the stool base 1 is placed over the floor plate a with its inclined lugs 2 in lateral relation to and clear of the inclined planes 7 of the floor plate 4 as illustrated in dotted lines in Fig. 1. After which, and by a partial turning movement of the stool base 1, its inclined lugs 2 are brought into interlocking engagement with the inclined planes 7 of the floor plate 1 to effect a substantial con nection between the parts and a forcible contact of the bottom of the stool base with the surface of the floor.

lVit-h a View to maintain and in most instances effect a final interlocking engagement of the parts as above described, a headed screw bolt 8 has bearing in a side wall of the hollow stool base 1, with its screw hread shank extending into the cavity of said base for operative engagement with screw threaded orifice formed in a lug or extension 9 of one of the aforesaid radial ribs 6 of the floor plate 1, so that with a rotation of the screw bolt 8 in one direction the aforesaid inclined formations will be drawn more closely together in a holding engagement, while with a rotation of the bolt 8 in the opposite direction, the tendency will be to cause a separation of said inclined formations, when it is desired to detach and remove the stool to another location.

Having thus fully described my invention what I claim as new, is

1. In a floor fastening for pedestals, the 4 of an open eral inclined lugs in its interior, a floor plate formed for fixed attachment to a floor and for enclosure by the base, said floor plate having a plurality of inclined planes complementary to the inclined lugs aforesaid for interlocking engagement therewith in a turning movement of said base, and means for holding the parts in the described interlocked condition.

2. In a floor fastening for pedestals, the combination of a pedestal base of an open bottom shell form having a plurality of lateral inclined lugs in its interior, a floor plate formed for fixed attachment to a floor and for enclosure by the base, said floor plate having a plurality of inclined planes coniplementary to the inclined lugs aforesaid for interlockingengagement therewith in a turning movement of said base, and means for holding the parts in the described interlocked condition, the same comprising a headed screw bolt having bearing in said base and operative engagement with a screw threaded lug on the floor plate.

3. In a floor fastening for pedestals, the combination of a pedestal base of an open bottom shell form having a plurality of lateral inclined lugs in its interior, a floor plate formed for fixed attachment to a floor and for enclosure by the base, said floor plate having a plurality of inclined planes complementary to the inclined lugs aforesaid for interlocking engagement therewith in a turning movement of said base, means for effecting a journal engagement between the base and the floor plate, and means forholding the parts in the described interlocked conditio a. In a floor fastening for pedestals,the combination of a' pedestal base of an open bottom shell form having a plurality of lateral inclined lugs in its interior, a floor plate formed for fixed attachment to a floor and for enclosure by the base, said floor plate having a plurality of inclined planes complementary to the inclined lugs aforesaid for interlocking engagement therewith in aturning movement of said base, means for effecting a journal engagement between the base and the floor plate, the same comprising a central depending collar on the base and a series of radial ribs on the floor plate with the inner ends of the ribs having spaced relation to each other and abutment against said neck, and means for holding the parts in the described interlocked condition.
