To all whom it may concern:

Be it known that I, EDWIN E. SLICK, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Transferring Metal Blooms, &c., of which the fOllOWlI)" is a full, clear, and exact description, reference being had to the accomanyiug drawings, forming part of this speciiication, in which A Figure 1 shows in plan view an ingot-carrying car ada ted to form part of my improved a paratus or delivering blooms or ingots to t 1e feed-tables of rolling-mills. Fig. 2 is a side elevation thereof shown in osition in the feed-table and in the act of elivering a bloom thereto. Fig. 3 is an end elevation of the car and a side elevation of the feed-table, and Fig. 4 IS a detail end view of one of the guide bars or rails.

The purpose for which I have es ecially designed in improvement is to a 0rd means 'for transferring blooms and ingots of metal from cars to the feed-tables of rollin -mills; but while I make special claim to sue application thereof I wish it to be understood that the invention as defined in my broad claims is not limited thereto, but that with suitable modifications the principles thereof may be applied to the depositing of covers on vertical as will be understood by the skilled mechanic.

In the drawings, 2 represents the frame of the feed-table or conveying-table by which ingots, blooms, billets, &c., are conveyed in a rolling-mill to or from the rolls, and 3 3 are the driven rollers of such table.

4 4 are the rails of a track leading from a heating-furnace and extendin transversel to the table and across the which frame is depressed or recessed, as shown in Fig. 3, in order to permit crossing of the rails.

5 is the frame or truck of a metal-ca car mounted upon wheels 6 and PlOVldQi with a suitable number of rollers or other cross-su orts 7 for su porti the metalv pg i ed f ir eating-furnaces and to other uses,

ame thereo formed with inclines b and with depressions 0, so that when the cars pass thereover the wheel-flan es' engaging these bars or, supplemental ra' s will travel u the inclines so as to raise the car and will t en descend in the depressions to lower the car, the position of the car when lowered beingat the middle of the feed-table. As shown in Fi 1, the flanges of the wheels at one end of t e car are set at opposite sides of the wheelffrom the flanges at the other end of the car, the fla es of one painbeing on the inner sides of t e wheels and the flanges of the other pair being on the outer sides of the wheels. Correspondingly, the set of su plemental rails 8 on one side of the feed-tab e are placed on the outer side of the rails 4, while on the other side the set 9 are placed on the inner sides of said rails, so that the wheels having inner flanges will not engage the rails 8, while wheels havir iglouter flanges will not engage the set '9. e rails 8 and 9 are so spaced a art that the flanges of the wheels engage t 0 same simultaneously, thus lifting the car in vertical lines.

The operation is as follows: A billet or bloom 10 having been placed on the rollers of the car the car is drawn on its track up to and across the feed-table. The front wheels of the car, for the reasons above ex lained, pass the first pair of guide bars or rai s without engaging them; but when they reach the second air of guide bars or rails on the far side of t e feed-table the flanges of both pairs of wheels, simultaneously engaging the inclined portions 6 of the respective 'de bars or rails, ride up the same and lift t e car, so that the metal iece thereon shall be elevated above the leve of the feed-rollers 3. Then when the flanges of the wheels reach the depressions 0 they descend simultaneously in these depressions and lower the car, so as to bring the rollers 7 below the surfaces of the feed-rollers 3 and to deposit the metal iece upon the latter. rollers then carries the metal piece from the car, and as the ,car is drawn forward the wheels rise on the inclines c and again descend to the level of the track.

It is clear that the car may be used not onl for delivering metal pieces to the feedtable, as above explained but also for removing them from the feed-table.

The advantages of m invention will be appreciated by those ski led in the art.

Q The apparatus issimple and automatic in its operation and affords a very efficient means for transferring and conveying metal.
