page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-
This invention relates to roller skates and consists in mechanism for righting
the truck with relation to the foot plate; second, in the employment of inti-
frictional rollers in the axle bearing; third, in an absorbent collar preventing the
objectionable escape of the lubricating material, and fourth, in other improvements
as fully set forth in the description.
The clamping mechanism for securing the skate to the foot, consists of cross bars
or plates having at their outer ends upwardly projecting flanges adapted to clasp.
the shoe sole. On the inner ends of the said plates are pending bosses having
screw-threaded openings, through which pass transversing screws having right and
left hand threads thereon. The ends of the screw are square, so as to be readily
operated by a suitable key. The said cross-bars move in guides secured to the foot
plate.
Brackets forming bearings for the shaft portions of the castings or trucks are
attached to the foot plate of the skate, which trucks furnish bearings for the axles
of the wheels.
The said brackets are each composed of two arms, the angle or meeting place of
which has a notched portion or recess constituting one of the bearings for the
shaft portion of the truck. The upper portion of the outer arm of each bracket is
extended in the direction of the length of the skate, and is provided with a socket
or recess. The lower outer edges of the extended arms, and the depending portions
of the brackets form angular notches which, with the walls of the socket constitute
the upper bearings for the shaft portions. The upper portion of each shaft is
rounded and inserted in the socket and is provided with trunnions or horizontal
pins having angular upper faces, the said pins resting in notches when the axles of
the wheels are at right angles to the longitudinal line of the foot plate.
On the lower portion of each shaft is a shoulder and tenon, the latter being
stepped or inserted in an opening in a lever, which lever is provided with a foot

page_text: adapting it to be engaged or secured to the upper portion of the inner arm of the
bracket.
A screw is provided in each bracket, having its threads engaging in an opening
in the inner arm of the bracket, and has a head between which and the lever is
secured a spiral spring, the latter having between it and the body of the screw, a
rubber spring which serves to prevent the working loose of the screw.
°
By the mechanism described, the foot plate may be oscillated by the foot of the
skater, whereby the trucks are cramped, so as to run the skate in a curved line.
The oscillation of the plate causes the angular notches to move across the axial line
of the horizontal pins, thereby forcing the latter from their seat in said notches,
which action forces the shafts against the springs. Owing to the annular faces of
the pins, one side of the foot plate is thus depressed, and its wheel is pressed to
the rear, the other side of the plate being raised and its wheel advanced. When
the pressure is removed, the springs force the shaft to the position necessary for a
straight line movement. By means of the screws, springs and levers, the tension
of the shafts is regulated as may be desired.
Each casting or truck has a cylindrical portion, which is preferably recessed
centrally between its end bearings thus forming a cavity or chamber adapted to
contain in part the anti-frictional rollers which are placed between the axle and
the bearing. Owing to the recess, the rollers travel more steadily and easily than
they would if the bearing extended the entire length of the cylinder. The recess
has communicating with it an oil nozzle for the lubrication of the axle, the same
being provided in its side with a feed opening and air escape. In said nozzle is
fitted a gravity plug or stopper for closing the opening, the head of the stopper
being adapted to abut against the projection of the bracket,, when the stopper is
raised, to prevent the displacement thereof.
To prevent the escape of oil from the chamber I place on the inner portion of
the wheel a collar of absorbent material surrounding the ends of the bearing, and
provided with a flanged portion projecting between the bearing and the wheel;
this, I cover with a cap whereby the oil is effectively prevented from escaping.
To distribute the pressure or weight of the skater upon the body plate, and also
to more rigidly connect the brackets, the rod or brace is employed, the threaded
ends of which are secured in openings in the outer arms of the bracket, the rod
passing through openings in the levers and inner arms of both brackets. The
screw of the rear clamping device has a central, rounded peripheral groove in which
the said rod rests, thereby preventing the lateral movement of said screw, and thus
displacement of the same. The rear bracket may have integral therewith an
upward projection which serves as the heel plate of the skate.
The anti-frictional rollers have conical ends, so as to offer little resisting surface
when forced against the washers which are placed between the bearings and the
wheels.
I would observe that various modifications of portions of the device may be made
without departing from the invention. I therefore do not limit myself to the exact
mechanism as herein described to produce the results named.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to roller skates, and consists first in mechanism for righting
the truck with relation to the foot plate; second, in the employment of anti-
frictional rollers in the axle bearing; third, in an absorbent collar preventing the
objectionable escape of the lubricating material; and fourth in other improvements,
as fully set forth in the description.
In the accompanying drawing.
Figure 1 represents an underside view of a skate embodying my invention.
Figure 2 represents a side elevation, partly in section, of the skate shown in
Figure 1.
Figure 3 represents a sectional end view, showing the bearing of the wheels with
conical-pointed, anti-friction rollers.
Figures 4, 5 and 6 are views of different portions of the skate shown in figure 2.
Similar letters of reference indicate corresponding parts in the several Figures.
A represents the foot plate of the skate, and B, B represents the clamping
mechanism for securing the skate to the foot. The said clamping mechanism
consists of cross bars or plates B¹ having at their outer ends upwardly projecting
flanges adapted to clasp the sole of a boot. On the inner ends of the said plates B¹
are pending bosses having screw-threaded openings, through which pass the
transverse screws B2, having right and left hand threads thereon. The ends of
the screw are square, so as to be readily operated by a suitable key. The bars B¹
move in guides C secured to the foot plate A.
DD represent brackets attached to the foot plate of the skate and forining
bearings for the shaft portions of the castings or trucks E, E, which latter furnish
bearings for the axles of the wheels A¹.
The brackets D D are each composed of two arms, the angle or meeting place of
which has a notched portion or recess constituting one of the bearings for the shaft
portion F of a truck E. The upper portion of the outer arm of each bracket is
extended in the direction of the length of the skate, and is provided with a socket
or recess a. The lower outer edges of the extended arms, and the depending
portions of the brackets form angular notches c, which, with the walls of the
sockets a, constitute the upper bearings for the shaft portions F. The upper
portion of the shafts F are rounded and inserted in the sockets a for a portion of
the depth of the latter. The upper end of each shaft is also provided with trunnions
or horizontal pins d, having angular upper faces e, f, as shown in Figures 2, 3 and 4,
the said pins sliding in the notches c when the axle of the wheels moves relatively
to the longitudinal line of the foot plate.
On the lower portion of each shaft F is a shoulder g and a foot h, the latter being
stepped or inserted in an opening in the lever G, which lever is provided with an
extension adapting it to be engaged or secured to the upper portion of the inner
arm of the bracket.
HH represent screws engaging in openings in the inner arms of the bracket.
Each of these screws is provided with a head h¹, between which and the lever G is

page_text: secured a spiral spring J, the latter having between it and the body of the screw
an india-rubber spring K which serves to prevent the working loose of the screw H.
By the mechanisin described, the foot plate A may be oscillated by the foot of the
skater, whereby the trucks are cramped, so as to run the skate in a curved line.
The oscillation of the plate A causes the notches to move across the axial lines of
the horizontal pins d thereby forcing the latter from their seats in said notches
which action forces the shafts F against the springs J through the levers G. Owing
to the annular faces e and f of the pins d one side of the foot plate is thus depressed,
and its wheels pressed to the rear, the other side of the plate being raised and its
wheels advanced. When the pressure is removed, the springs J force the trucks E
to the position necessary for movement in a straight line. By means of the screws H,
springs J and levers G the ease with which the truck E move relatively to the foot
plate is regulated as desired.
M represents the cylindrical portion of each casting or truck E which portion is
preferably recessed centrally between its end bearings k, thus forming a cavity or
chamber, adapted to contain, in part, the anti-frictional rollers m, which are
placed between the axle N and the bearing. Owing to the recess, the rollers m
travel more steadily and easily than they would if the bearing extended the entire
length of the cylinder. The recess has communicating with it an oil nozzle m¹, for
the lubrication of the axle, the same being provided in its side with a feed opening
and air escape n. In said nozzle is fitted a gravity plug or stopper p for closing
the opening m, the head of the stopper being adapted to abut against the projec-
tion of the bracket D, when the stopper is raised, to prevent the displacement
thereof.
To prevent the escape of oil from the chamber 1, I place on the inner portion of
each wheel a collar O of absorbent material surrounding the end of the bearing,
and provided with a flanged portion projecting between the bearing and the wheel,
this I cover with a cap P whereby the oil is effectively prevented from escaping.
To distribute the pressure or weight of the skater upon the body plate, and also
to more rigidly connect the brackets, the rod or brace L is employed, the threaded
ends of which are secured in openings in the outer arms of the brackets, the rod
passing through openings in the levers G and inner arms of both brackets.
The screw B2 of the rear clamping device B has a central, rounded peripheral
groove in which the said rod L rests thereby preventing the lateral movement of
said screw, and thus displacement of the same.
The rear bracket may have integral therewith an upward projection R which
serves as the heel plate of the skate.
The anti-frictional rollers m have conical ends, so as to offer little resisting
surface when forced against the washers which are placed between the bearings
and the wheels.
I would observe that various modifications of portions of the device may be
made without departing from the invention. I therefore do not limit myself to
the exact mechanism as herein described to produce the results named.
