Improvements in Brick-cutting Machines.
I, FRANZ JOHANN SCHNELLE, of 207a, Uellendahlerstrasse, Elberfeld, in the
Empire of Germany, Engine Builder, 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 an improvement in brick-cutting machines.
In the accompanying drawings Figs. 1 and 2 represent a front view of the
machine, with the cutting apparatus turned up and down respectively.
Fig. 3 illustrates a device for preventing the removal of the brick-cutting
machine.
Fig. 4 being a section through the line A-B.
On the rails A, on which the wheels B of the brick-cuttng machine run, are
firmly mounted the bearings for the shaft b to which the crank-rod D is fixed.
The transmission of motion to the wheel axle is effected by means of the two-
arm connecting rod d, which is firmly mounted on the shaft b and pressed by
means of screw-bolts e against a bush, pushed on to the shaft c and retained by
means of adjusting collars f.
During the cutting operation the brick is held in position by the bearers g,
which are mounted on supports h, provided with wheels or rollers at the side,
which run on cuneiform rails k. The rails k are fixed to guide-supports 7.
The supports are pushed under the brick F automatically when the cutting
apparatus E is depressed, the operation being as follows:-
On the shaft of the cutting apparatus E a cam m is mounted, which acts with
a roller n against a bent-arm o, mounted on the guide-supports and thereby,
upon the cutting apparatus being pressed down, causes the guide supports / which
are guided in the rollers q arranged in the bearings p, to be pushed forward
under the machine as shown in Fig. 1. At the same time, the rails k slide under
the rollers of the supports and raise them, and thereby, also the bearers g
connected with them.
As soon as the cutting apparatus E is turned up, or opened, the cam m in turn
acts against the bent arm o sliding along the same, and thus causes the guide-
supports to slide under the machine, the rollers sliding along the rails k and
taking the position shown in Fig. 2. Thereby, also, the supports and therewith
the bearers take the lowest position.
To the carriage-frame C a rod r is fixed. The free end of this rod is bent so
as to form a roller bearings in which the roller is placed. The rod r is of such
a length that the roller t is below the rail u and when the carriage moves along
the rail, the arrangement of the roller t reduces the friction of the catcher on the
rail to the minimum and secures the carriage against removal from the rails.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. Brick-cutting apparatus in brick-cutting machines, the distinguishing
feature being that the bearers are mounted on supports which rest by means

page_text: of wheels or rollers on cuneiform rails, fixed to sliding rods, which are pushed
forwards and backwards in roller bearings by the movement. of the cutting-
apparatus, the bearing supports being raised and lowered by means of the cunei-
form rails.
2. A device for securing brick-cutting carriages against removal from the rails,
the distinguishing feature being the arrangement on the carriage frame of rods,
the free ends of which support a roller, with which they catch beneath the
rails.
3. The improved brick cutting machine substantially as described with
reference to the drawings.
