COAL-'LEVELING MACHINE FOR BEEHIVE-OVENS.

Specification of Letters Patent.

Patented Sept. so, 1913.

Applicationfiled February 6, 1911. Serial No. 606,827.

To all whom itmay concern:

,Be it knownthat I, JOHN H. HUHN, a citizen of the UnitedStates of America, and resident of Fairmont, county of Marion, State of West Virginia, have invented certain new and useful Improvements inCoal- Leveling Machines for Beehive-Ovens, of which the following is a specification.

My invention relates to improvements in coal leveling machines for use in connection with bee-hive coke ovens, and particularly to that class of leveling machine which are carried upon a carriage which moves on a track along the top of a row of cokeovens, and particularly to that class of carriage which are propelled by electrical means, and which carry electrical devices for actuating the mechanism carried thereon.

The invention will best be understood by reference to the accompanying two sheets of drawings in which- Figure 1 is a vertical elevation of the leveling tool attached to the table of the carriage upon which it moves, shown in connection with a bee-hive oven in' a vertical cross-section. Fig. 2 shows a plan view of the arms in their closed position. Fig. 3, a plan view with the arms partly open, and Fig. 4, a plan view with the arms full open; Fig. 5, an elevation showing the arms in their open position. Fig. 6, plan view of the mechanism for operating the arms, and Fig. 7, a cross-section through the vertical shaft of the leveling tool.

Similar letters refer 'to' similar throughout the several views.

In the drawings, Orepresents the oven, which is provided with a central opening O inthe top and a door D at one side. 7 1

S represents one of a pair of rails, ex tending along the top'of a row of coke ovens upon which moves the carriage, carryingthe leveling device. V y

In the carriage 1 is the truckwhich carries a rotating table 13, driven from any parts convenient source of power, which in turn carries two arms 14, mountedon trunnions 15, so that they may be adjusted angularly,-

34, which is arranged to slide vertically 1n a suitable head 57. This head is mounted on the ends of the arms 14, as shown in Fig. 1. It is furnished with the bushings 42, and is recessed for the toothed wheel 28, which engages with a Worm wheel 27, arranged upon suitable hearings in the head 57, through which a rotary motion may be imparted to the tube 34, by means of a sprocket and chain 26 on the shaft of the worm 27. As shown in Figs. 1 and 7 the hollow tube 34 has a keyway 34 its entire length. The toothed wheel 28 is provided with an internal key 28*. The tube 34 is free to move up and down within the head 57, and the wheel 28. No matter in what position the tube 34 may be, it may always be rotated by the wheel 28, on account of the internal key, attached to the latter. In theinterior of the tube 34 there is a shaft 64, which is arranged to be held stationary or rotated with the tube 34. The shaft 64 carries at its lower extremity the cross head or arm 68, shown in Figs. 1 to 5. The tube 34 is closed at the top by the head 81, which is of the form shown. The head 81 is surrounded by a plate 51, which supports it, so that the tube 34 and the head 81 rise or fall with the plate 51. The plate 51 is extended to support the shaft 60 and to support the friction arm 12, which will be described later. The shaft 64 passesup into a suitable seatin the head 81, and is provided at the top with the friction wheel 62. Surrounding the wheel 62 is the friction band 11, actuated through the arm 12, and the shaft 60 by the lever 61. 'To the lower extremity of the tube 34 is attached the arm 40.

The form of the arms employed. in the present structure for leveling the coal is best seen by reference to Figs. 2 to 5. These are composed of a series of upper and lower horizontal pieces, 31, as shown in Fig. 5, be-

.tween which are pivoted the horizontal tating the tube 34:, while the shaft 64 is held stationary, it will be seen that the pantographic arms are extended or retracted according to the direction of rotation. The tube 34, and with it the leveling arms 81 and 35 are raised and lowered within the head 57, by means of the cable 24, attached to the yoke 54, which passes over pulleys on the top of the tower 17, and is connected with the drum 23, upon which it winds.

The method of operation is as follows: hen the apparatus is in use the tube 34: is drawn up until the arms 31 and 35 are close to the head 57. The carriage is then run along on the track to the point where the arms come directly opposite the opening 0 in the coke oven. The entire mechanisnris then lowered by releasing the drum 23.- Motion is then given the tube 34 and the lever 14 thrown to the on position, which tightens the friction band 11, and prevents the friction wheel 62, shaft 64, and arm 68 from turning. This extends the arms 31 and 35, horizontally. Then the arms are extended, the operator releases the lever, which swings back to its former position, allowing the friction wheel 62 and shaft '64 to rotate with the tube 34:. l/Vhen the oven is properly leveled the operator reverses the motion of the tube 34, and again throws in the lever 14, preventing the shaft 62 and arm 64 from rotating. This retracts the arms to their closed position, andallows the mechanism to be drawn up out of the oven.
