Application filed August 17', lSl. Serial No. 250,322.
T0 all 'whom t may conce/rn Be it known that I, JOHN B'. OWENS, a Citizen of the United States, residing at Metuehen, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improveineiez,l in Kiln-Cars, of which the following '1s/a" specification.
This invention relates/to cars which are used in tunnel kilns for conveying the clay products or wares to be tired.
Kiln ears' are entered in the tunnel, one at a time, finally making up a train which completely fills the tunnel, the successive cars pushingx those in advance. Suitable mechanism is employed to push the cars into and through the tunnel. Each car, ineluding;` the one at the extreme head end of the train, is directly engaged by the next ear thereafter, the entire train being pushed, as a unit, through the tunnel.
Cars used in tunnel kilns are sometimes a. little distorted in shape due to imperfect manufacture, or, to the very high temperature to which they are subject in the kiln. `Should one or more cars be a little twisted from such causes and consequently not squarely engage where they contact with each other,or, engage at the corner of the car, instead of at the central portion of the end thereof, the corner of the car will be broken oil, or. the ear forced out of alinement with the other ears by reason of the .force necessary to move the train of cars in the kiln. Y
f Kiln cars are subject, as at present constructed, to passage of air from below the cars to the space above them, and, also, to heat passing `down from above the' cars to the space below them, thus destroying the seal which should be maintained between the section of high temperature above the cars, where the clay products and ware are being tired, and the section of the tunnel wher/e the running` gear of the-cars travels, which should be kept cool to avoid injury to the runningl gear. Attempts heretofore made to maintain theA integrity of. the seal between the ends of the cars and prevent the aforesaid air and heat leakage have not been successful. So far as l ain aware.
The object of iny invention is the provision, rst, of improvements whereby the car ends engage only at the center, even though the car be of imperfect construction or has become warped from the heat in the tunnel; second, improvements whereby the ear endsl become automatically sealed, when engaged, thereby preventing' the passage of air upwardly, or heat downwardly, between the ends of the cars, and which, furthermore are adapted to have a clay wad, asbestos rope, or the like, applied to perfect said seal.
.These objects are attained by the provision, irst, of a novel bumper at one end of the car, adapted to engage the center of the end of the ear in advance so that the, pushing pressure is applied only at the cen ter of each car; second, of novel tongue and groove ends on the ear, whereby the grooves on one car receive the tongues on the adjoining ear to effect a seal between the car ends,
which may be perfected by the use of a clay wad, asbestos rope, or the like; third.` of the bumper and sealing construction in conjunction with each other.
A. further object-of the invention is the provislon of a kilncar which has'grooved side sills adapted for thereception, and anchoring, of fire brick or lireclay should it become necessary to protect the side sills from the heat.
My kiln car may-be of cast. iron, or, of channel iron riveted together.
. In the accompanying drawings:
Figure l is a plan View; 7

Fig. 3, an end elevation;
Fig. el, a detail section on line 4 1, Fig. l;
Fig. 5, a similar View on line 5 5, Fig. 1;
Fig. 6, a detail plan view, partly in section, showing thefends of two ears enga-ged;
' Fig. T, an enlarged detail section on line 7*?, (5, and Figs. 8 and 9, details of modified seals for the car ends.
The ear 1 which is of cast iron, integral throughout, is preferably provided with a rim or flange 2 extendingupwardly from its topalong its four sides to retain slabs fire clay, Fig. 4, which. constitute its fireproof platform or deck on which the Clay products or saggars are supported.
The side sills 3 have `grooves et adapted to receive irek brick or fire clay 8, Fig. 4, should it become necessary to protect the sides of the ear from tie heat, These grooveswill anchor and retain irebrick or from the other end sill of the car.
heat .from passing downivl tire clay, being made of suflioient depth for thatl purpose. e
At one end of the oar are two horizontal tongues 5 which are separated at their inner ends by a space 6, leaving an exposed surface 7 in line with the longitudinal axis of the oar. The tongues are preferably rounded at their outer edges 8 and are tapered from their bases to their ridges in cross-sectional form, as shown in Figs. 5 and 7 At the other end of the car are two horizontal grooves 9 which are slightly deeper than the extent of projection of the tongues The :grooves 9 are adapted to receive the tongues 5 on the adjoining car to seal the joint be tween the car ends and thus prevent air from passing upwardly,7 troni 'below and I rdly from above the cars between the endsbt the latter. This seal 'is automatically established when the cars come together. The seal may be perfected by laying a clay wad, asbestos rope, or a like, 5a on the tongues prior to engagement of the cars, so that said Wad will be mashed and otherwise conform to the joint established ybetween the car ends', as shown in Fig. 7.
Projecting a very small distance, in practice aboht one-eighth of an inch (although l do not onine myself to that dimension), from that end of the car having the grooves 9, is a center bumper 10 which is adapted to engage the surface 7 of the adjoining car when the oars come together. rlthe slight projection of this bumper beyond the car end provides fori the holding apart ofthe end sills o`f the cars on either side of the center a distance of about one-eighth of an inch and results in the pushing pressure being applied solely at the center of the end sill of a car. The bumper prevents the cars from bein throvvn. out of alineinent should they be dlstorted from imperfect construction, or, from the heat of' the kiln.
The Wheels 11 may be mounted, as by roller lbearings 12, ion short independent axles 13 secured to hangers 14, inte ral with the car 1, b screws, or other llistening means 15. learance is thus obtained beneath the car, which cannot be had when full-length axles are used.
lVhile l have illustrated the tongue and roove seal as being provided on the east iron car 1, the tongue and groove may, instead, be provided on the ends oir the tireproof platform or derek 2a, as shown in Fig. 8 at 15, with an interposed headresisting Wad 5". l
Sealing of the oar ends may be eiected, in another modification, 'by the provision of 'horizontally arranged upper and lower, parallel angle-plates, or the like', secured to one car end and delining a groove adapted to receive the end of the next car, as shown in Fig. 9 at 16, with an interposed headresisting Wad 53.
The Jforegoing modifications are intended to be cove-red 'by the claims.
What l, olaini is: 'l
1. A kiln car having horizontal grooves at one end, With an intervening lbumper at the center of the car end, 'and horizontal tongues at its other end, with an intervenin Contact surface, said grooves being adapte to receive tongues on the yend of another kiln car, said tongues being adaptedto pro ject into grooves on the end of another kiln oar, and said bumper land contact surface bein@1 adapted, respectively, to engage their corresponding mating parts on another kiln car, whereby the spaces between adjoining cars may be sealed and the pressure of one car onV another Will be applied to the centers of the ends thereof, said grooves and tongues being adapted to be sealed by an in-v terposed heat-resisting material.
2. A kiln car having a one piece frame provided with an integral projecting push* ing bumper at the center of one' end to en gage the center of the end of a correspondr ing kiln car.
3. A kiln car having grooves at one end. tongues at its other end Correspondinol to the grooves, and a projecting pus iing bumper at its grooved end. y
4L.. A kilncar having a pair of horizontal grooves at one end a pair ot corresponding tongues at its oth Vr end, said parts being adapted to be sealed by an interposed heat resistingmaterial, and means whereby one car may be pushed 'by another ear while maintaining the car ends of adjoining cars in slightly separated relationship.
5. A kiln oar having side sills provided with longitudinal grooves, and heat-resist ing material contained within said grooves. (SpA kiln car having a one-piece frame Whose side sills are provided with longitudinal grooves, and'heat-resisting material contained Within said grooves.
