Improvements in Brakes.
Year: 1899

page_text: I, EDWARD THOMAS CLEATHERO, of The Hollies, Barrington Road, Altrin-
cham, in the County of Chester, Engineer, do hereby declare the nature of this
invention to be as follows:-
The present invention relates to improvements in brakes and is specially
applicable to such machines as atop cylinder printing machines.
In carrying it into effect, a shoe is mounted to work in suitable guides from
and to the brake wheel on that side of the latter opposite to the bight of the
brake band. The shoe is pivotted upon a lever introduced between the end of
the brake rod and the bruke band.
The brake power is applied to the lever in the proper direction for forcing
the shoe on to the brake wheel at the same time that the band is pulled down
thereupon.
The shoe guide may be a vertical slot in a plate suspending the shoe from the
axle of the brake wheel, and a stud projecting from the machine frame into a
vertical slot in the shoe plate.
The brake rod is fitted with an adjustable spring or equivalent means for
regulating the power applied.

Improvements in Brakes.
I, EDWARD THOMAS CLEATIERO, of The Hollies, Barrington Road, Altrin-
cham, in the County of Chester, Engineer, do hereby declare the nature of this
invention and in what mauner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
The present invention relates to improvements in brakes and is specially
applicable to stop cylinder printing machines and the like.
Referring to the accompanying drawings which are to be taken as part of
this specification and read therewith:-
Figure 1 is a side elevation:
Figure 2, a front elevation from the left hand of Figure 1 omitting portions
of the brake mechanism:
Figure 3. a plan of Figure 1: and

page_text: Figures 4 and 5 are side elevations of the front and rear end clips respectively
of the band brake.
1 is a shoe mounted to work in suitable guides from and to the brake wheel 2
radially to its axis and on that side of the latter which is opposite to the bight
of the brake band 3. There are two guides illustrated, one of them a slot 4
in the top of the shoe frame 5, and standing about a stud 5 screwed into the
projecting end of the shaft 6 of the brake wheel 2, and the other 8 standing in
the same way about a stud 9 projecting from the machine frame 10.
11 is a transverse shaft turning in suitable bearings and carrying a cam 12
which engages with an anti-friction roller 13 on the adjacent end of a brake
lever 14, having its fulcrum at 15 in a bracket 16 carried by the frame 10. The
opposite end of the lever 14 has the bottom end of the brake rod 17 pivotally
connected to it, the top end of the said rod 17 being connected to the shoe
lever 18 by being passed through it and then fitted with a nut 19. 20 is a
cushioning spring surrounding the brake rod 17, and both compressible and
resilient to a suitable extent between a collar (not shown) fast on the said rod 17
below it, and the respective end of the shoe lever 18 above it, against which
end the top of the said spring bears directly against an interposed washer 21.
The hole 22 in the shoe lever 18 through which the brake rod 17 is passed has
convex sides and the respective end of the said lever is convex also beneath the
nut 19 and above the washer 21 to facilitate the co-operation of the said lever 18
and rod 17. The shoe lever 18 has its fulcrum in a stud 23 carried by a fork 24
projecting downwardly from the shoe frame 5. 25 is the front clip of the
brake band 3. It is made fast to the frame 10 in the usual way. 26 is the rear
clip of the same band 3. It is made fust to that end of the shoe lever 18 opposite
to the brake rod 17.
The action of the invention is as follows. As the cam 12 rocks the brake lever 14,
the brake rod 17 is pushed up through the hole 22 in the shoe lever 18. As
soon as the cushioning spring 20 is compressed, the adjacent end of the shoe
lever 18 is rocked up, thereby pulling the brake band 3 down upon the brake
wheel 2. As the said band is so pulled down the fulcrum 23 of the shoe lever 18
rises and the shoe brake 1 is pulled upwards against the wheel 2, so that from.
the moment in which the said shoe brake 1 bites the brake wheel 2, it and the
band 3 brake the wheel 2 from opposite sides.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declaro that what
I claim is:
The combination of brake band; shoe brake on frame working in guides;
shoe lever to apply both the brake band and the shoe brake: and means for
nclunting the said shoe lever; substantially as described with reference to the
accompanying drawings.
