APPARATUS FOR CHARGING BILLETS, ARS,.800., INTO FURNACES SPECIFICATION forming part of Letters Patent N 0. 385,249, dated June 26, 1888.

Application filed November 10, 1887. Serial No. 254.7?2. (No model.) v

Be it known that I, FRED H. ,DAinE.Ls, a citizen of the United States, residing at \Vorcestcr, in the county of Worcesterand State of Massa chusetts, have invented certain new and useful Improvements in Apparatus for Charging Bil- ]ets or Bars into Heating-Furnaces, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in make anduse the same.

The object of my present invention is to provide, in an apparatusfor charging billets or bars of metal into a heating-furnace, an overhanging carrier for introduction of the material into the furnace without contact with the hearth; also, to provide means for preventing the tipping of the forward'end of the'carrier when advanced into the furnace.

Another object is to provide a stop or barrierto operate adjacent to thefurnace-entrance from its supports on the carrier or effecting its deposit within the furnace.

These objects I attainby mechanisin,the naplained, the particular subject-matter claimed In the drawings, Figure 1 is a vertical seemy invention. Fig. 2 is a plan vi w of the same, and Fig. 3 is a transverse section of the charging-carrier and top of the support-frame.

Referring to parts, Ain'dicates the supporting-frame, which is made of suitable form to support the operative parts, and B indicates the furnace into which the material is to be charged, which-furnace maybe of the ordinary well-known kind as employed in rolling-mill plants. The upper part of the frame'is provided with aseries of guiding-rolls, a, on which the carrier 0 is'supported as it runsforward and-back, the frame being of suffieient length furnace. The carrier consists, preferably, of two long beams, 0, arranged at thedesired distanceapart, and connected by rigid bracing near-their rear ends, and having betweenthem Fig. 1, being supported by the working position at will and under control of I the billets or materials to be charged are laid.

These supports are in the present instance metal rolls rotatablyjournaled in connection with the respective beams O, as indicated. Suitable counter supporting-rolls, a, are fixed to the main supporting-frame to overcome or resist the upward tendency of the rear end of the carrier when its load is projected forward into the furnace to. such an. extent that the leverage would tendto lift the rear extremity. The rolls a extend over the beamsO, and are firmly connected by their supporting-bracl xets with the frame A, thereby preventing any upward movement of the'rear end of the carrier. 6

The carrier 0 is advanced into and retracted from the furnace longitudinally by means of a chain belt running on wheels K and guidesheaves m, or by any other. suitable operating mechanism adapted to give reciprocative ac- 7o tionto the carrier. As the carrierO, with its load, is advanced into the furnace-chamber, it moves forward without contact with the furnace-hearth or other part of the furnace, the beams projecting or overhanging, as shown in 7 5 frame A and its rolls a at proper level and in proper lateral alignment. N indicates a removable or adjustable barrier adapted to be entered into the mouth or door I) of the furnace in rear of theload of billets, (which are indicated by dotted lines I in Fig. 1,) for the purpose of preventing backward movementof the charge of billets, orany of them, when the carrier is retracted. Said barrier in the present instance is supported upon a shaft that works in bearings fixed to the wall of the furnace or to a frame adjacent thereto, so as to swing up and down for carrying the engaging end of the barrier to and go from working position. A gearand pinion, as

at N, or other suitable mechanism,is combined withsaid barrier for moving it to and from the operator. j I In some instances the projecting portion of the charge-carrierO may be made shorter than the material to be charged, the billets being permitted to extend forward past the end of the carrier, not far enough, however, to give [00 their forward ends preponderance. In the operation, while the carrier is at retracted position, the billets or materials'to be charged are placed upon the charger between the beams O, resting upon the'rolls D The carrier is then advanced and its forward end containing the load or charge is projeoted into the furnace. The barrier N is then dropped or swung down, so as to introduce it at the entrance of the furnace in rear of the billets. The carrier is then retracted,while the barrier prevents backward movement of the charge.- Henee the rolls D are drawn out from beneath the load, thus depositing and leaving the billets within the furnace.

The apparatus may be made for charging from one to forty billets at a-tirne, as desired. The side bars, 0, may be of channel-beams or other suitable shapes of metal bars, of a size and strength suitable to meet the requirements of service in any particular case;

In cases where it is desired to shift the carrier from one position to another wheels A may be provided for supporting the frame upon the floor, ground,;or platform in front of the furnace. 1 i

. In lieu of making the barrier N to swing up and down on an axial shaft, it may in some instances be arranged toslide to and from its working position, suitable guides being provided for directing its course of movement.

'What I clairn'as of my invention, and desire to secure by Letters Patent, isw 1. In apparatus for charging heating-furnaces, thecombination, with the furnace and the guiding-frame, of a charge-carriercolnposedof longitudinal beams and transverse supporters, adapted to overhang from said frame :when in advanced position, and means for imparting movement to said carrier, to, project the load forward into the furnace withfoutcontact with the hearth or other portion thereof, as hereinhefore set forth. p

2. In apparatus for charging heating-furas set forth.

naces, the combination of areciproeating carporters, whereon the billets or charge is placed and supported while advanced into the furnaee, and a stop or barrier that engages with the char e and effects the deposit thereof within t e furnace, substantially-as set forth.

4. In a charging apparatus, in combination with a heating-furnace, a charge-carrier, an adjustable barrier adapted tobe introduced at the furnaceentrance in -ear of a the charge or.

billets on said carrier, and mechanism for ele- {i 5- vating and depressing said barrier into "and from the furnace-entrance, substantially as set forth. I

. 5. In a charging apparatus,;the combination of an overhanging charge-carrier mounted-for reciprocative aetion,-having guides'for said carrier, a supporting-frame, and a counteract ing guide or roll, as va, connected with said frame, for sustaining the rear end ofsaid charge-carrier against up ward niovementwhen the charger is projected forward, substantially Witness my hand this 15th dayof October, I
