HEAT TREATING APPARATUS Filed Jan? 16, 1957 2 Sheets-Sheet 2v nvemor TY/i. 56h mug/z (1/2 11 attorney Patented Ma 1c, 1937 UNITED STATES Tama e HEAT TREATING APPARATUS Theodore A. Schraishulm, Toledo; Qhio, assignor to; Surface Combustion Corporation, Toledo, Ohio, a corporation of New York Application January '16,- 1937, Serial No. 120,923 3 Claims. 01. 2664) This invention relates to improvements in mechanism for guiding ordnance shells and the likefrom a heat-treating furnace to a quench tank having. therein an upwardly pointing finger 5 on which the shells are received one at atime and which serves, among other things, to transfer the shells to aconveyor leading out of the tank.
The object orobjects sought to be accomplished will more fully appear hereinafter. In the accompanying drawings wherein the preferred form of the invention is shown,-
Fig. 1 is a more'or less diagrammatic layout of the environment wherein the present invention has special utility;
Fig. 2 is an enlarged fragmentary view-showing in greater detail the combinational features of the present invention;
Fig. 3 is an enlarged sectional view on line 2-4 Fig. 4 is a front elevation (with parts insec- I .tion) of the apparatus shown'in Fig (2, and
Fig. 5 is a fragmentary view o fa detail.
Referring'to Fig. 1, Fl indicates a conveyortype heat-treating furnace, Q a quench'tank and 25 F2 a second heat-treating tfurnace.
convey a plural number of.rows of shells through the furnace. e furnace F2 may be of the same 3 type as the other furnace,
"Regardless of the type of conveyor associated- I with the furnace Fl, the-shells will be passed I through the furnace opeh end first, in a row, and' then beedis charged one at a time and open end 40 first into a chute C leading into the' quench tank Q. There will be one chute for'each row of shells and below eachchute is a finger which nor-' mally points upwardly ati'an angle in axial 'alinement with the discharge end of the chute for re-. 45 celving a downcoming shell. The finger thereupon the downward movement of the shells, the same being shown as a lever 2-l turnably mounted on a shaft 22 carried by a' support 23 and coupled; at
one end to a shock absorber shown as a coil 55 spring 24. I
Theshells or objects/ tc be heat-treated are ,passed first throughthe furnace Fl, then into thequench tank and finally throughthe furnace F2. The
' "conveyor-which,forms part of the furnace Fl is preferably, though not necessarily, of the type shown inpatent to Cone No. 2,057,367, dated October 13, l9 36,-the, same being adapted to The various fingers 20 are" shown as secured to a common shaft 26 turnably supported in'bearings 21. The fingers and the shaft are tubular and thelatter is coupled to a feed pipe 26 lead- 'lngfrom a pump (not shown) for supplying quenching liquid under pressure. It will, therefore, be seen that the fingers 20 also serve as noz- 'zles for discharging-quenching liquid into the shells as they come'down' their'respective chutes.
When all of the fingers 20 are mounted on a comlumon shaft 26 it will, of course, be understood that the shellsleaving the furnace Fl will e'nter'their respective chutes at one and the same time.
The'shaft 26, is turned back and forth the proper degree by any preferred'mechanism which '15 .i;shownas comprising a crank arm 28 amxed to fine end of the shaft and'a link 29 which couples the" arm to a power operated device 30 (see Fig.
I purposes may be considered as a trip 3| extending into one of thechutes C, the trip being actuated by a shell coming down the chute. Upstanding lugs 32 on the endless belt A remove the shells from the fingers 20 when the latter are in the dottedline' position shown in Fig. 2.
In apparatus of the kind described, it is essential that the discharge end of the shell chute shallalways be of the proper diameter to insure that the shells coming down the chute shall be properly guided onto the upstanding finger below the chute. Difizerent size shells will, therefore,
require different size chutes. Heretofore it has.
been a time consuming operation to replace a chute of one size with a new one of a different 35 size and suchoperation has usuallyinvolved draining of the quench tank which ordinarily will contain about. 10,000 gallons of oil. It is with the object in view of reducing. to a minimum thev time andtrouble involved in changing the size of the chute that the present invention has been made and the wayin which that object is accomplished will now be described.
' In accordance with the present inventiomthe lower part of the chute C consists of one of a 4-5 number of tubular sections 39 at the rim of a wheel 40 carried by a shaft 4| supported in bear ings 42 within the quench tank Q. The only difference between the sectionskis that their diamv eters are different. Consequently in, order to make the heat-treating apparatus 'ready to handle one of a number ofshell sizes it is merely necessary to turn the wheel 40'to bring theproper size chute section '39 into position with 'respect to the upper chute section. As shown in Fig. 3,
the chute sections a are interiorly provided with detachablegrading ribs 44 held in place by screws t H I v As shown in Fig.4 there will be .as many wheels 5 40 as there are chutes C. Turning-of the wheels may be effected in any preferred way as by turning a wheel handle I. amxed to the top of a turn rod 41 having a worm H in mesh with a worm wheel ll afiixed to the wheel. shaft ll all as clear 10 lyshown in Fig. 4. In order to lock the wheels in fixed position there may be ailixed to one end of the wheel shaft" a disk I having appropriately located holes for the reception of a locking pin 2 operable from outside of the quench tank- 115 Q by hand operated means 53;
What I claim is:
1. The combination with a quench tank and a furnace arranged and adapted to feed tubular objects to said tank and a finger in. said tank which normally points upwardly for receiving said objects thereon but which is supported for arcuate movement in a vertical plane whereby :the objects received on the finger may be removed a therefrom at a point angularly removed from the amen:
lected one of said tunnels into position to serve as the lower portion ofthe chute.
2. The combination-with a quench tank and a finger therein which normally points upwardly and which is adapted to receive tubular objects thereon but which is supported for arcuate movement in a vertical plane whereby the objects received on the finger may be removed therefrom at a point angularly removed from the point of reception on the finger, of means for conducting said objects onto said finger when it is upright,
said means comprising a turnable member which carries a plurality of tunnels of diiferent diameters, and means for turning said member to bring any one of said tunnels into axial alinement with the finger in its upright position.
3. The combination with a quench tank and a furnace arranged and adapted to feed tubular objects to said tank and a finger in said tank which normally points upwardly for receiving said, objects thereon but which is supported for arcuate movement in a vertical plane whereby the objects received on the finger may be removed therefrom at a point angulariy removed from the point of reception on the finger, of
' means for transferring objects from the furnace onto said finger when the latter points upwardly, said means comprising a chute, the lower portion of which comprises one of a number tunnels carried by a turnable member arranged in said tank.
