gitudinally movable bar having cutting means in combination operating it.

The accompanying drawing represents a sectional view of a rotary kiln in combination with my improved mechanism.

The kiln 1 is revolubly supported by roll- 'ers. 2 journaled in bearings 3 and is proyided at its lower end with the hood 4. The hood is carried by wheels 5 having a limwith mechanism for 'ited movement on the rails 6, extending in the direction of the kiln, the rails being mounted on a truck 7 having wheels 8 movable on the rails 9, transversely to the kiln.

- In this usual construction, the material in process of modulation is fed, by the inclination and rotation of the kiln, toward the hood 4, through which a heating agent is introduced, and in the usual operation rings 10, which interfere with and eventually stop the operation, are formed on the kiln linings by the adhesion of the material rendered plastic by the heat. These rings are removed, in accordance with my invention, by a bar 11 provided with teeth 12, which are adapted for cutting through the adhering material; the bar and teeth being hollow for the circulation of water, which is introduced through the pipe 13 connected with the hose 1% and withdrawn through the hose 15. The bar 11, which passes through the port- 16 in the hood, has its end exterior to the kiln connected with hoist blocks 17, which are carried by hangers 18 suspended from trolleys 19 movable along the overhead rail 20; the blocks having their chains 21 connected with the collars 22 on the bar. A roller 23, journaled on a bearing 24 carried by the hood, acts as a fulcrum for the bar when its rear end is lifted by operating the hand chains 25 of the Specification of Letters Patent. Application filed March 13, 1911. Serial No. 613,978.

hoists, to effect the desired engagement of the cutting teeth 12 with the ring 10.

A link belt or wire cable 26 is connected by eye bolts 27 with collars 28 on the bar 11 and passes over a wheel 29, j ournaled in bearings 30 on the hood 4, and a wheel or drum 31, which is ournaled in bearings 32. The drum 31 is reciprocated, to reciprocate the members 26 and 11, conveniently by a spiral gear 33 fixed thereto and a revoluble shaft 34 having a spiral gear, 35 engaging the gear 33. The shaft is journaled in the bearings 36 and provided with a worm wheel 37 which is engaged by a worm 38 revolved, by a wheel 39, the latter being connected by ,a belt 40 with the-reversing motor 41.

In operating the apparatus, the rotation of the kiln is stopped, the bar is inserted, and its rear end is elevated so as to engage its teeth with the ring to be cut, by operating the hand chains. The motor is then operated in reverse direction and acts through the intermediate mechanism on the link belt or cable to reciprocate the bar and cutthrough the ring which, being severed, is readily broken and removed. It will be understood that when the bar has been drawn back by the motor mechanism to the limit permitted thereby, it can be wholly removed by detaching the eye bolts and adjusting the collars so that it can be carried wholly by the movable blocks.

As the bar can be inserted and withdrawn readily, it need not be in the kiln subject to the heating action during the nodulating operation, as in usual constructions, but it is designed for use after the ring has formed when the latter can be removed by'cutting it in several places, upon which the several sections will fall of their own weight, particularly if allowed to slightly cool and contract.

Having described my invention I claim: 1. The combination, with a rotary kiln, of a longitudinally reciprocating bar having one or more projections thereon adapt-- ed for cleaning the lining of said kiln.

2. The combination, with a rotary kiln, of a longitudinally movable bar having a laterally projectingcutting member adapted for cleaning the lining of. said kiln, and means for reciprocating said bar.

3. The combination, with a rotary kiln,

of a bar adanted for cutting difierent sec-.

tions of a ring adherin to the interior of said kiln, means vvhere y said bar. is fulcrumed, and means for moving said bar longitudinally. -4. The combination, with a rotary kiln, of a longitudinally movable water cooled bar having one-or more cutting teeth thereon ada ted for' acting upon the various parts 0 a ring of material adhering within Witnesses:

said kiln, a fulcrum for said bar, and means for reciprocating said bar.
