TO, ALL'wHo'M IT MAY concnnnr v v I Be it known that I, S. A. DABBACH, of Newhurg,'in'the county of Orange, and in the State of New York, have'invcnted anew and improved Furnace and Tender for Heating and Delivering Metal Bars; and I; do
hereby declare, that the following is a full, clear, and exact description thereof, which will enable ,those skilled in the art to make and use the same, reference .heing'had to the accompanying drawings, forming part of this specification, in which drawing i Figure 1 represents a longitudinal section of this invention, the line ma, fig. 2, indicating the plane 'of scctio'ns Figure 2 is a horizontal section thereof, taken in theplane indicated by the line y y, figil.
Figure 3 is a detached section of the feed-bar.-
Similar lettersindicate corresponding parts, H g p A represents my furnace, which is composed of the ash-pun- B and; the fire-pot Said fire-pot ,rests on the top edge of, the ash-pan, and it-is provided witha grate, a, and with asocket, b, which rechives a pivot, c, on; which the fire-pot revolves. This pivot projects from the top cf-a'standard,'which rises fi omthe bottom of the ash-p an; The fire-pot is made of a cast-iron jacket, lined with fire-brick, and it is c'o'vrdby a bonnet, D,
which, in practice, will be suspended from chains, so that it can be readily raised and lowered.
The fuel is introduced through a pipe, E i'rom above, and fromthe bonnet emanates a pipe,"F, which serves to carry of the smoke. The air which is required to support the combustion asses in from below through the grate a. From the periphery of thefire-pot pi'ojects a series of pins, 01, w ich are acted on by a hinged reciprocating latch, 'e, so that an intermittentrotarymotion is imparted to'the fire-pot.
' The latch e is hinged to aslide, f, to which a reciprocating motion is imparted by acam, g, which is secured to the circumference of a drum, G, mounted'on a shaft, H, to which a revolving motion is imparted by any suitable power. As the slide is pnshed out in the direction of the arrow marked on it in fig. 2, the latchdrops over one of the pins din the fire pot, aud as the slide recedes, the fire-pot is caused to revolve, I p
In the side of the fire-pot is a series of holes, It, at equal distances apart, and through these holes the bars to be heated are introduced. These holes are at such a depth below the upper edge of the furnace that the bars or blanks, on being introduced into said holes, are surrounded on all sides by the incandescent fuel in the furnace, and that they are uniformly and economically heated to the desired white heat. v
These bars are placed into -a box, I, to which a transverse shaking motion is imparted by means of a com,
2', which projects from the driving-shaft H, and which acts on a lever, j, (see fig. 3,) whichis connected to the box I, and the upper end of which is pressed up against the shaft H by a spring, Ia. When the come acts on the lever j, ,the bar I is'moved in the direction of the arrow marked near it in fig. 8, and one of the bars after the other drops down into a cavity, Z, in the platform which supports the box. In said cavity is fitted a pusher,- m, to which a reciprocating motion is imparted by a cam, 11, onthe drum G, and the rotary motion of the firepot is so timed that one of the holes, h, in its sides, comes opposite the cavity 1 whenever the pusher m begifis to move forward in the direction of-the arrow marked thereon-in fig. 2, and the bar, which has been deposited in the cavity l, is pushed into thehole of thc fire-pot.
As the motion of-the apparatusprogresses, one hole after the other in the fire-pot receives its bar, and each bar is carried round with the fire-pot until it arrives opposite the discharge-mechanism. During this time the bar is heated.
The discharge-mechanism consists of two spring-jaws a, which are pivoted to a slide, 12, to which a reciproa eating motion is imparted by the cam '12. This cam acts on a pivot g, which projects from the secondary slide 1', which is situated on'the top of, the main slide p, and theinne'r end of which forms a. wedge, r.
' In moving backin the directionof the arrow marked on the slide r in fig. 2, the two slides are connected to each other by a spring-latch, s, which is secured to the main slide, and which catches over a pin, a, project ing from the secondary slide, and in moving forward in the direction opposite to said arrow, the two slides are aconnected by a sprihg-iatch, t, which is attached to the main slide, and catches over-a pin, t, projecting from ithe secondary slide.
When the main slide has reached the rear end of its stroke, the spring-latch s strikes a stop, it, and the secondary slide is disengeged,,so that it can move back far enough to withdraw the wedge r from between the shanks of the jaws o, and said jaws are thrown open by the action of their springs. At the same time the pin t is thrownunder the latch t, and both slides begin their inward stroke inconjunctionl But when the jaws o have'come closeup to the periphery of the fire-pot, the latch it strikes a stop, 2:, whereby it is raised so as to disengage the slide 1' from the mainslide p, and as the motion of'thecam proceeds, the secondary slide r centinues its motion, and the wedger' is forced between the shanks of the jaws a, causing them to close upon the bar, which projects from the fire-pot, and which at that moment has arrived in the proper position to bc'grasped by said jaws. .After the-jaws have been closed upon the bar, the two slides reeede, having been locked together by thelatch s, and the heated bar is withdrawn from the furnace.
When the main slide has reached the .rear end of its stroke, the secondary slide rccedes'stillfurther, as previously described, the wedge r is withdrawn from between the shanks of the jaws, tbejaivs open, and the heated bar drops down on the chute K, which leads to a bolt-heading machine,nr to any other mechanism where said heated bars are to he further operated upon. a
i It is obvious that the properheatingof the bars depends principally upon the construction of the furnace and upon the position of the holes 71. 'In' an open furnace, have not succeeded to produce the required heat, and -I have therefore covered my furnace with the bonnet D, whereby the draught is increased and the heat is confined in the furnace, and by placing the. holes hat a certain depth below the top edge of the furnace, the bars, on being. introduced into the furnace, are surrounded by the incandescent fuel, and they are readily heated to the required temperature, as previously stated And, furthermore, by giving to the box I a transverse shaking motion, the bars are caused to'drop down before the pushernvithout fail, and the operation of the furnace is rendered regular.
By 'this apparatus the operation of heating metal bars and delivering the same to a bolt-heading machine, or to any other mechanism, is materially simplified and rendered entirely automatic, so that no further attention is required, except to keep up a'preper supply of bars to the feed-hox I, and a requisite supply of fuel to the fire-pot.
What I claim as new, and desire to secure by Letters Patent, is-- 1., The arrangement of a revolving furnace, A, provided with holes h in its sides, and covered with a bonnet, D, in combination with the mechanism described for introducing and removing the bars,-substantially as and for the purpose described.
2. The devices herein described for giving to the feed-box I,.containing the blanks, a transverse shaking motion, substantially asand for the pnrpose set forth.
3. The latches a t andpins s t, in combination with the jaws o, wedge 1", slides r, and revolving fire-pot 0, all constructed and operating-in the manner-end for the purpose herein shown 'and described.
