VTHADDEUS NEELY, OF MUNCIE, lNDIANA.

,A ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 259,708, dated June 20, 1882.

Application lcd March 11,1882. (Model.)

wear of such skates and reducing the cost of manufacturing' them.

A further object is to improve the construction of the fastening devices whereby the skate is secured to the foot. j

My said invention consists, therefore, of a .roller-skate having the peculiarities of construction hereinafter particularly described and claimed, whereby the before mentioned objects are accomplished.

Referring to the accompanying drawings,

which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a top or plan view of a skate embodying my said improvements;- Fig. 2, a side elevation-of the same; Fig. 3, a longitudinal vertical section on the dotted line z z,- and Fig. 4, an under side plan thereof, one of the wheels beingremoved in orderto show the wheel-frame, its pivot-shaft, and the wheel-axle more plainly.

1n said drawings, the Yportions marked A represent the footpiece of the skate; B, the wheels; G, the axle; D, the wheel-frames 5 E,

' the pivot-shafts for said frames; F, brackets attached to the foot-piece A, containing bearings for said shafts; G, pieces of rubber interposed between said wheel-frames and said brackets; H, preferably metallic heel-pieces; 1, straps attached thereto J, clamps tosecure the front part of the foot to the skate; K, screws for operating said clamps, and L metallic portions in which are bearings for said 4clamps and said screws.

peculiar considerably broader on the face than those commonly employed. This gives a better bearing on the floor than two single wheels, besides reducing the number of wheel-edges liable to catch on irregularities in the Hoor-surface just one-half, and, because of the greaterwidth of the wheels, the actual danger in a still greater proportion. By the peculiar construction and mounting of the wheel-frames D all the elasticity and scientific attributes of the double roller skates are secured in the form shown.

The brackets F are, as will be noticed, continuous from a point about vertically above the wheel-shaft to about horizontally-opposite the same, with a bearing-shaft, E, running diagonally across from one point to the other, on which the wheel-frame rests. This shaft is exactly central. to the breadth of the wheel, and the wheel-shaft is in such relation thereto that the bearing force comes squarely upon its bearings, whereby the amount of friction produced in running the skate is reduced toa minimum.

A piece of rubber, G, is interposed between the wheel-frames D and the brackets F for the usual purpose of righting the skate-foot when tilted over and of preventing any except an enforced rocking or tilting movement. of the Wheels and wheel-frames.l

The heel-pieces H are simply pieces of sheet metal suitably formed and attached to the heel l of the foot-pieces A, as shown, and take the place of the more expensive combined metal and leatherheel-piece which is commonly used.

It has alip, h,which is turned over and clinched upon the strap I, as is most plainly shown in Fig. 3, which forms all the fastening necessary for said strap.

The clamps J are pivoted at j to the metal portion L, and pass horizontally through said piece at Z. The upwardly-projecting portions of these clamps are operated to grip the sole of the skaters boot or shoe by the screws K, which pass through screw-bearings la on the metal piece L.' This formsa very simple and reliable fastening.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is---v-Y 1. In a roller-skate having two wheels only, rocking or oscillating bearings, the bearingshafts beinglocated centrally above said wheels and running from apointaboutvorticaliy above l the Wheel-shafts on an angle toward the ioor, substantially as shown and specified.

2. The combination, in a roller-skate, of the 5 brackets F, the shafts E, the wheel-frames D,

4. The oomhinatio11,with a skate, ofthe soleciamps J, pivoted atj, and the screws K,where by said clamps are operated, substantially as 15 set forth.

In witness whereof I have hereunto set my said several parts being' arranged and operating substantially as shown and spcoied.

3. The combination,with a skate, of the heelxo piece H, having` turned-over lip h, and the strap I, said lip being clinched down upon said strap,

which is thus secured, substantially as set forth.
