DOUBLE COKE-PUSHER SPECIFICATION forming part of Letters Patent No. 723,493, dated March 24, 1903.

Application filed June 5, 1902. Serial No. 110,358. (No model.)

To all whom it may concern:

Beit known that I, F'REDERIC W. O. SCHNIE- WIND, a citizen of the United States, residing at New York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Double Coke'- Pushers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to means employed for discharging coke from-coke-ovens, especially of that class of ovens'known as the Otto-Hoffman type, has for its object the balancing of the weight of the pusher and relieving the supporting-car and machinery of.

the strain incident to projecting a pusher from one side of the car only, and consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a side elevation of my invention; Fig. 2, a top plan view; and Fig. 3, a vertical transverse section on line 3 3, Fig. 1.

Reference being had to the drawings and the numerals thereon, 1 indicates a car or truck on which are supported two oppositely.- movable pusher-bars 2 3, each having a head 4, and the pusher-bars and their heads may be projected into and withdrawn simultaneously or alternately from coke-ovens 5 6 in opposite batteries of ovens by suitable motors 7 8, connected to a pinion 9, engaging a toothed rack 10 on the upper surface or edge of the pusher-bar by gear- wheels 11, 12, 13, 14, and 15, and the bars are held down to their seats or bearings on rollers 16 by a roller 17 engaging smooth tracks or ways 18 18 on each side of the track 10. The car is propelled by a provided with inclined arms 30, connected limit the outward movement of the jib by the arms engaging stops 32 on the main frame. To each jib is secured a bracket 33, on which are supported revoluble carriers 34 34, secured to a shaft 35 and mounted in bearings 36, and

and form no part of my invention separately considered, but are fully described and claimed in application Serial No. 110,380, filed herewith by Edwin A. Moore, of Philadelphia, in the State of Pennsylvania.

By providing two oppositelyprojected pushers on one car one pusher balances the other as they are being projected into and Withdrawn from coke-ovens arranged in batteries placed opposite each other, with the ovens of one battery in advance of the ovens of the opposite battery-and in line withthe pushers, and one car serves both batteries of ovens, thus dispensing with one car and one attendant or engineer, and the batteries can be placed .closer together than under the present practice of construction and operation, thus saving space between parallel batteries of ovens. An additional advantage of the construction lies in the extended support afforded the pusher-bars by the additional length of the car which carries the two pushers.

All the motors are operated from a cab (not shown) on the car and are under the control of an attendant.

Having thus fully described my invention, what I claim is w 1. A coke-pusher provided with two opposite balancing pusher-bars, means for supporting said bars, and a separate motor for each bar, whereby the bars may be reciprocated simultaneously or independently of each other; in combination with two opposite OVGHS.
