BRAKE SHOE FOR TYPESETTING MACHINES
Robert J. Lloyd, Detroit, Mich.
Application May 16, 1938, Serial No. 208,271
`9 claims. (Cl. 1919-30)
The present invention relates generally to an
improvement in typesetting machines and par
ticularly to a brake mechanism for restraining
the movement of the assembler rail while aline
5 of matrices are being assembled in the assembler
box.
An ob-ject of the present invention is the pro
vision of a brake shoe that will not lose its bite
on the assembler rail.

A still further object of the present invention
is the provision of brake shoes that will prevent
looseness in the line o_f mats being formed and
thus eliminate V-shaped openings and transposi~
or upper shoe, and a detachably secured means
in the lower shoe, the said means adapted for
engagement with the assembler rail.
Other objects of the invention will be mo-re
fully understood from` the following description
and claims when the same are read in connec
tion with the drawing accompanying and form
ing part of this specification in which:

brake I4 that comprises a lever l5, the lower 10
portion of which is provided with ears I@ and il.
My novel improved brake, comprises an upper
shoe I8 and a lower shoe i9. The upper shoe
I8 is provided with a bore 20 into which is
mounted for rotatable movement a ball 2l, the 15
bore 2B being slightly in excess of the diameter
of the ball 2l. To the right of the midway
point, the shoe I8 is provided with a through
transverse bore 22 that receives a threaded mem
ber 23, the threaded member engaging a thread 20
ed bore 24 in the lever E5, detachably securing
the shoe I8 to the lever. It is to be noted that
the top face of the shoe I8 impinges the lower
face of the ear HG. The lower shoe i9 is pro
vided with a bo-re 25 into which is detachably 25
secured a ball 26. Centrally of the bore 25 is a
bore 2l and this bore serves as a means for
punching out the ball 26 for replacement or
shoes in gripping position.

which the assembler rail mechanism is secured.

matrice chutes, Il the assembler rail and l2 the
Pivotally mounted at I3 on the frame 9 is a

A still further object of the present invention
is the provision of a rotatable means in the top
20
of the assembler rail to its normal position, parts
being sho-Wn fragmentarily.
Referring to the drawing, the numeral 9 rep

fragmentarily.
Figure 8 is an enlarged detail view of the lever
carrying the shoes and illustrating the shoes out
55 of contact with the assembler rail for the return
turning the ball over to replace a worn spot on
the spherical face of the ball.
The provision 30
of a ball provides a gripping means that may be
used for an indefinite time due to the fact that
only a small area of the spherical surface en
gages the rail. To the left of the midway point,
the shoe I9 is provided with a transverse bore 28 35
whichl receives a threaded member 29, the
threaded member 29 engaging a threaded bore 3i)
in the lever I5, detachably securing the shoe lil
to the lever. The bottom face of the shoe i9
rests on the upper face of the ear Il. In View 40
of the differences in construction of the two
shoes as recited, the upper shoe i8 is marked
with the letter U and the lower shoe I9 with the
letter L to insure the proper positioning of the
shoes on the lever I5.
45
As illustrated in the drawing, Figures l, 7, and
8, the shoes are assembled on the brake lever
I5, the balls disposed diagonally and due to this
positioning of the balls a more positive gripping
of the assembler rail is eii‘ected. The provision 50
of the balls, provides a gripping means in which
only a small spherical portion oi the balls en
gage the edges of the assembler rail, thus in
suring a tighter grip than the flat edge brake
shoes commonly used.

The description about to be made of the opera
tion of the brake involves mechanism well known
in the art and it is deemed unnecessary `to give
same in minute detail, therefore a general de
scription is deemed sufficient. In the operation
of my improved brake shoes, as the star wheel
(not shown) deposits the matrices on the assem
bler rail, the assembler rail I I is moved to the left
against the tension of a spring (not shown) that
10 is connected to an arm 3l’ on the lever 3|, the
spring tension acting against the assembler rail
through the intermediate pivoted lever 3| having
said lower shoe provided with a punch bore for
its lower end 33 connected to one end of a link
permitting insertion of removing means for said
in said shoes, one of said shoes provided with
spherical removal means, said spherical means
disposed at an angle to each other and adapted to
bear on the top and bottom edges of said rail.
4. A brake for assembler rails of linotype ma
chines comprising an upper shoe and a lower
shoe, gripping means mounted in said shoes bear
ing on the top and bottom surfaces of the rail,
the vgripping means in the upper shoe loosely
mounted for rotative movement, the gripping 10
means in the lower shoe ñxedly mounted therein,
34, the other end of the link 34 connected at 35 gripping means.
>5. A brake for assembler rails of linotype ma 15
15 to the assembler rail II. Asv the assembler rail
II is moved to the left during the composition of . chines comprising an upper shoe and a lower shoe,
a line, it is held in its displaced position by the spherical means mounted in each of said shoes, a
brake I4 that comprises the v.lever I5,»the lower portion of said spheres adapted for engagement
end of which carries the upper shoe I8 in which with the edges of said assembler rails, and means
20 is mounted the rotatable bearing 2i that engages " inthe lower shoe for permitting insertion of re 20
the upper edge of the assembler rail II and the
lower shoe I 9 having the` ñXed bearing 26 that
moving means íor said spherical means.
engages the lower edge of the assembler rail as
illustrated in the enlarged detail view of Figure
machines comprising a lever, an upper shoe and
a lower shoe, sperical means mounted in said
25 7 of the drawing.
The brake shoes I8 and I9
are held in contact with the assembler rail II by
the sp-ring 393, one end pulling on the brake lever
I5, one end of the spring being secured to the
brake lever Iâ and the other end secured to the
30 bracket 3l on the frame. When the composed
line is transferred to an assembling elevator (not
shown) means well known in the art release the
brake I4, the brake lever assuming the position
illustrated in Figure 8 of the drawing and a1~
lowing the assembler rail and itsl associated mech
anism to return to its normal position. It is to
be noted in Figure 8, that in the return position
the balls do not engage the assembler rail.
My improved brake shoes are adapted for use
on typesetting machines, such as the Intertype
and Linotype machines and require no- change of
mechanism, simply remove screw in the old type
of shoes and replace the old shoes with my im
proved ball grip shoes.

Changes in detail may be made without de
parting from the scope of the claims hereto ap
pended.

1. A brake for assembler rails of typesetting
machines, comprising a lever, shoes detachably
secured to said lever and spherical meansy mount
