' IMPEOVED BALL-GASTEE..
To ALL WHOM IT MAY OONCERN:
Be it known that we, SAMUEL S. HIOKOK, of Methuen, Essex county, Massachusetts, and DANIEL B. CLEMENT,
,of Boston, Suffolk county, Massachusetts, have made o. new and usefnl'invebtionof an Improved Ball-Caster 4desired object, the screw'being in tbe centre'ofsnch base.
and do hereby declare the following to be a full, clear, and exact description of the same, due reference being had to the accompanying drawings, making. part of this specification, and in which-'- Figure l is a. side elevation, and Figure 2 a vertical and central section of a balllcasterconstructed in accordance-with .thc ideas of Imy invention. Figure 3 is a perspective view of one of the friction-Wheels or rollers to be hereinafter described, while Figure 4 is a perspective. v iew lot' one of the slotted-'or-recessed brackets for supporting thc friction-wheels. The object of this'invention is to produce a caster for use upon 'tire-prooi` safes, pianos, trunks, and-various other objects, which shall allow such objects to. be moved aboutwith equal facility in any direction, and with ease. The invention consists in -a spherical ball or globe, retained in place upon the lower end or-portion of a support or base by an annular c up or sleeve, which partially surrounds it, and allows it to revolve easily thereinj' the base itself being supported upon or over theball'by means of an'interposedserics of anti-friction wheels or rollers, duly suppd'r'ted within recesses made in the base, and turning upon axles duly inserted therein; A'the whole being substantially as hereinafter described.
By-referring `'tothe accompanying d'rawingspit will be seen'that the caster is shown at a" as composed" of a.l spherical ball` a, partially enclosed by an annular cup or sleeve, b, the lower 'edge 'of which extends belowthe centro of the ball, in order to preventits dropping out of the same, while the 'u'ppen periphery of the cup is serrated or recessed, and issecurcdin a suitable manner to a base or support, c.
The upper par't of this base is provided with a. screw for the purpose of readily applying the caster to the The base, furthermore, is recessed or notched, as shownfat d d, Site., for reception of a series of six or any suitable number of wheels or rollers e e e, tte., supported and turn-ing upon axlesfff, Snc., the ends ofwhich' areinserted within recesses ggg, &c., formed in opposite sides of the pendent posts ith-h, making part of tbe base, c, before mentioned, the line of rotation of the wheels e e e beingin n. radial line frein the centre of thebase, Ao, or thcreabonts.
The ballor globe a is to be of sutiicient size to bear upon or touch the peripheri'es` of all the wheels `e e e. The mode of supporting and securing the axles f ff Ste., in their supporting-posts h h 7i, as shown in the drawings, is to forni in the lower end .ofsuch posts,` and exten-dingupward, a. slot'or recess, z', into which the end ofthe roller-axle is inserted, there being one of these recesses upon each side ot` the post; the axle being.
retained therein by a block of leather or other suitable material, which is inserted within the lower end of the.v said recess, and below the axle; the block of leather being in turn secured in itsproper place by the same' screws which serve to confine the' annular cup to thc hase, or'by any suitablo'means.
The construction of the above-'described caster' admits of very great strength and simplicity of parts. As the point tif-resistance or pressure is always nt its centre, there is no danger of breakage. as wit-h the ordinary caster;
'As the line of rotation'of the rollers' e e, duc., radiates 'from the centre of the'base outward, the ,full advan tage of these rollersiis obtained'in whatever direction the main ball o r sphere is rotated, thus enabling the object to which the' caster is attached to be moved about in various .directions with' equal facility and with ease. It obviates the great objection, conamon to. ordinary casters, of becoming"set" in one direction, and which, upon being drawn' along over a carpet orileor, tends, to injure themto a serious extent.l
We'claim as our invention, :rnd-desire to secure by'Letters Patent ofthe United States- The ball-caster, made in-twosections, as -hercin described, the onescction consisting of the base'c,`.constructed'with the slotted legs h, in which the axles'ofrollers e are held, and the other ot' the cup b, withthe caster-ball which it holds,attached to seid base, in the manner and for the purposes shown andsp'ec iiied.- SAML. is. HIOKOK,
DANIEL B. CLE/MENT.
