To all whom 'it may concern: 4

Be it known .that I, FRANK- J. LEARMAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in vBlackleadi'n -Machines, of

. which the following is a spec' cation.

forcing the liquid t ough a mova le discharge s out against -the surface of the matrix in t e bath to coat the same with the black lead, and thisl ump preferably takes the li uid from the ath so as to keep the same 1 uid in circulation.

The o ject ofthis invention is to provide an actuating mechanism for the movable discharging spout which will be simple in construction and positive 1n o eration and which will automatically move t e discharge spout back and forth in different directions, or universally over the matrix so that the entire surface of the same 'Will be completely and evenly coated with the black lea In the accompanying drawings: Figure 1 is a perspective view of a matrix coating machine provided with a spout actuating mechanism embodying the invention. Fig. 2 is a plan view thereof, partly in-section, showing various different positions of the discharge s out in dotted lmes. Fig. 3 is a sectional e evation thereof in line 3-3, Fig. 2.

Like letters of reference refer to like in the several figures.

A represents the tank for containingl. the black lead bath in a matrix coating mac ine, B a pump connected therewith by an intake pipe b and provided with a discharge pipe b', a portion at least of which is flexible and terminates in a suitable nozzle b2. C re resents a Wax -matrix which rests in the tank eneath the nozzle b2 upon a support or frame D. All of these parts may be of any suitable or usual construction. v

v E and F represent vertical shafts jourparts driving the vertical shafts E and naled in suitable bearings e f on two sides ofv the tank A and provided at their upper ends with cranks e and f which are connected by pitmen or links e2 and f 2 to the free end of the discharge spout. The tpitmen are preferably connected by ball an socket joints e3 and f3 to a clamp g embracing the spout to allow a free movement of the spout in different directions.

Any suitable means may be em loyed for In the construction shown, drive shafts H and I are journaled in suitable bearings on the sides of the tank A at which the crank shafts E and F are located, and are connected by intermeshing bevel gears h and 'i which cause them to turn in opposite directions. One of the shafts, for instance the shaft H, is provided with tight and loose Tpulleys K for a belt for drivingthis shaft. he drive shafts H and I are connected to the crank shafts E and F by intermeshing bevel gear wheels Z and Z', respectively. This arrangement of the shafts and connecting gears causes the vertical crank lshafts to revolve in opposite directions, and the gears are so proportioned that the crank shafts are driven at different speeds. The cranks e andf are also preferably of different lengths. By reason of this arrangement of the shafts and gearing, the cranks continually change their relation to each other and shift the discharge spout to which they are connectedv in different directions, and to different positions. As the cranks travel at vdifferent speeds, they can only occupy the 'same relation to each other after a number of revolutions of their cranks, depending upon the relative speed of the same. The spout is therefore moved back and forth over the matrix in different paths and eventually repeatedly covers'all parts of the matrix. A feW of the many dierent positions of the cranks and discharge spout are shown by full and broken lines in Fig. 2. The same results can be secured by any suitable drive mechanisms for rotating the cranks in opposite directions at different speeds. The parts of the actuating mechan ism should be proportioned and arranged to give the most effectual movement of the spout and prevent the same from assuming a dead center position or coming into contact with the Walls of the tank.

I claim asmy invention: 1. In a black-leading machine the c ombicharging liquid against the su ace of a ma-.

trix in said tank, cranks located on different sides of the tank and connected to said s out, and means for revolving said cranks at dier ent speeds, whereby the spout is shifted to various different positions in the tank, substantially asset forth.

3. In a black-leading machine the combination of a tank, a movable s out for discharging liquid against the su ace of a matriX in said tank, cranks located on different sides of the tank and connected to said spout7 and means for revolving said cranks in opposite directions at `different speeds whereby the spout is shifted to various different .posis tions in the tank, substantially as set forth.

4. In a black-leading machine the combination of a tank,.a movable s out for discharging liquid against the s trix in said tank, cranks located on different sides ofthe tank, links connected to the cranks, universal joints connecting the links ace of a ma-` to the spout, and means forrevolving said cranks `1n o` posits directions at different` s eeds Where y the spout is shifted" to various rfferent positions in the tank, substantially as set forth. l

5. In a black-leading machine the combination of a tank, a movable s out for discharging liquid against the su ace of a matrix 1n said tank, two actuatin devices con-` nected to said spout for'control ing the movement thereof, and mechanism for producing a relatively different motion of said actuating devices whereby they cause an irregular movement of said spout, substantially as set forth.

6. In a black-leading machine thecombi-` nation with a tank, a movable ,discharge spout emptying into said tank, actuating arms connected with saidspout and arranged at an angle to each other, and means for moving said arms at diHerent speeds whereby said spout is shifted to various different ositions in the tank, substantially as set orth.

Witness my hand, this 7th day of May,

A FRANK J. LEARMAN.
