Sept. 1-7, 1929. H. SAHLMANN 29 ROLLER SKATE Fiied May 28. 1928 IN VEN TOR.

A TTORNEY Patented Sept. 17, 1929 UNITED STATES PATENT'OFFICE HENRY SAHLMANN, OF BROOKLYN, NEW YORK ROLLER SKATE Application filed May 28,

This invention relates to a roller skate in which the rollers of the skate are all placed in alignment.

The usual roller skate has four rollers rectangularly positioned on the skate. Such an arrangement, as is well known ZLDClObVlOUS, is not as effective in turning as the single runner used on ice skates.

It is accordingly an object of this invention to provide a roller skate embodying constituting a material part of this disclosure, and in which t Figure 1 is a side View of theskate.

Figure 2 is a bottom view of the skate.

Figure 3 is a rear view of theskate.

Figure 4- is a viewtaken a'longline 1-4 of Figure 1.

Referring to the drawings the skate is shown to comprise a plate 5 which is adjustably connected to the toe-plate 6 by means of a screw threaded bolt and wing nut 7, and the plate 5 has integral therewith a heel guard 8. The toe-plate 6 has mounted thereon the clamping members 9 which are controlled by the'threaded bolt 9", this structure being common in roller skates.

Rive-ted to the under sides of

plates

5 and 6 are the

supports

10, 11 and 12, each of which is flared at its lower extremity to form a jaw 16 adapted to embrace the tubular portion 15 of the roller bracket having the vertical side portions 14:. In assembling the skate, the jaw 16 is slid over thetubular portion 15 and then the sides of the j aw are pressed tightly around the portion 15 to securely hold the latter, as shown in Figure 3.

A plurality of rollers 17 18, 19, 20 and 21 are mounted in the roller bracket between the sides 14 by means of the bolts 22 and

nuts

22 and 22", the bolt being surrounded by a 1928. Serial No. 281,005.

spacing member 25 which prevents frictional contact between the rollers and the sides 14-, the rollers being rotatably mounted on the members 25. f a

In the skate shown in Figure 1, five rollers are used, one of the rollersbeing mounted in the inclined portion of the roller bracket, I

thus simulating the ice skates as far as possible.

From the above description it will be seen that there has been provided a simple roller skate which obviously is more eflicient in operation than the common roller skate in which thearollers are rectangularly posi tioned. The rollers in alignment facilitate turning movements and the inclined portion of the roller bracket enables the performance of stunts which heretofore was impossible with the usual roller skate.

The foregoing disclosure is to be regarded as descriptive and illustrative only and not as restrictive orlimitative of the invention, of which obviously an embodiment may be constructed, including many modifications, without departing from the general scope herein indicated and denoted in the appended claim.

Having thus described my invention, what- I claim as new and desire to secure Letters Patent, is

A roller skate having a foot supporting plate, supports fixed to the underside of said plate, said supports having jaws at their lower ends, a roller bracket havinga tubular portion gripped by the aws on the supports, said bracket having vertical side portions, spacing members positioned between said side portions, and rollers rotatably mounted on said spacing members, said rollers being in alignment.

In witnesswhereof Ihave aflixed my signature. a I t HENRY SAHLMANN.
