Rohren-SKATE..

'SPECIFCATION forming part of Letters Patent No. 306,384, dated October 14, 1884.

Application tiled March 4,V 1884, (No model.) l

To @ZZ whom t may concern:

Be it known that I, HENRY CARTER, a citizen of the United States,and a resident of Concord, in the county of Merrimac and State of New Hampshire, have invented a certain new and Improved Truck for Roller-Skates, of which the following is a specification.

My invention relates to that class of skates of which the foot-plate is permitted a limited amount of rocking both waysv from an imaginary vertical line perpendicular with the iioor,

which enables a skater to determine and control his course,while bearing his weight upon one or upon both skates when either going forward or backward, by a simple movement of thc ankle, thereby causing the sole of the shoe or boot to rest on an incline in either direction from said perpendicular line with the floor.

The nature of my improvements will be hereinafter clearly explained.

In the accompanying drawings, forming part of this specification, Figure l represents a front sectional elevation of m y improved truck, having the rolls mounted upon their axle ready for use. Fig. 2 is a centralvertical section at Y Y of Fig. l.' Fig. 3 is a detailed front view of the hanger, which is fastened by either screws or rivets to the sole-plate of a skate, and connected by a pivot to the axle-bearing. Fig. et represents a front view of the axlebearing in detail. Fig. 5 is an end View of the same, Fig, 6 being a plan View of Fig. 3.

Y front and back walls,

The line A in the drawings represents the iioor, and B the sole-plate, which may be of any approved form and thickness, and to which the hanger C is secured by means of screws or rivets D, passed through the iianges c at c', and thence into or through the said sole-plate. Said flanges c project from the c?, of the said hanger C, which are left open or without sides for threequarters of the distance (more or less) from the bottoni to the top thereof, the remainder being inclosed and provided with a shelf, c3, of suitable width, the purpose of which to be hereinafter described, and extending in each case from one to the other of the walls c2.

The axle-bearing E is made sufficiently long to separate the rollers Ithe proper distance,

having a hole, e', bored through it crosswise of and as near as possible to the hole c2 in said bearing, which carries the axle F, which is4 provided upon either end with the washers Gr and thepins H, for the purpose of holding the rollers I in position close to the ends of the bearing E.

To connect or disconnect the hanger C with the bearing E the rivet or pin J is provided, which passes through `the hole cL in the lower part of either wall c2 of said hanger, sustaining the said bearing E within the same by means of the hole e. Said pin J is provided with a suitable head at one end, the other endV having a hole, into which a split key or pin,

K, is inserted. Rubber blocks L of the proper size are placed within the top part of the hanger C, resting upon the shelves c3, acting as springs upon the arm e, the top part of which passes up between said rubber blocks L, by means of which the hanger and thc soleplate of a skate will be held central, except at such time as a skater desires to direct the course of the skate on a curve, when, by tipping his foot, the desired result will be accomplished. Spiral springs may also beused in place of the rubber blocks L with perhaps -equally as good results.

It may be well to mention here that the trucks (two of which are required foreach skate) are placed upon the sole-plate slanting away from each other. In other words, the hangers, `measured from center to center, when in position upon the sole-plate, would be nearer together by three-quarters of an inch (more or less) than would the axles taken from center to center, which accounts for the :door A, Fig. 2, being drawn on an incline.

Suitable oil-holes may be bored in the top part of the bearing E, as shown in Fig. 4, for the proper lubrication of the axle F.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In a truck for roller-skates, the hanger C, constructed substantially in the manner described, having flanges c, perforated with IOO holes c', and Shelves a, and pvoted by the piu constructed for the purpose of controlling and J and split pin K to the axle-bearing E, oarlimiting the tilting of the 5oleplate of a skate,l 1o

ryng the axle F and rolls I, and provided as specified.

upon the shelves cwthin the hanger C, and Y NATHANIEL E. MARTIN,

bearing upon either side of the lever e, so J. B. THURSTON.
