PALLET FOR SINTERING MACHINES Filed Sept. 23, 1930 I I IIII'I'IIIIIIIJ combinations of Patented Dec. 29, 1931 UNITED STATES REED w. HYDE, or summrr, NEW JERSEY PALLET FOR SINTERING MACHINES Application filed September 23, 1930. Serial No. 483,831.
This invention relates to pallets of the type commonly used in sintering ores and more particularly to a new and improved pallet having a portion of the side replaceable 5 whereby the pallet may be made to accommodate beds of ore of different thicknesses and whereby a burned portion of the side may be replaced without discarding the entire pallet. The invention is particularly applicable to perforate bottom pallets for a sintering ma- -chine but may be applied to pallets for other uses such as calcining. I
In sintering ores of different material, it is frequently desirable to utilize beds of difi'ercut thicknesses in order to obtain the proper sintering action. This has heretofore been accomplished by building a pallet with a wall sufliciently high to accommodate the deepest bed and using the same pallet'only partially filled when thinner beds of material are being treated. This is particularly disadvantageous inasmuch as satisfactory ignition of the charge is difficult to obtain when the pallet is only partially filled. Furthermore, the exposed edges of the allet are subjected to an excessive heat whic causes them to crack and wear out rapidly and the replacement of pallets thus damaged involves a considerable expense.
In accordance with the present invention theabove difiiculties are avoided by forming the sides of the pallets in two sections, one of which comprises a part of the usual pallet casting and the: other of which forms the I upper part of the sides and is replaceable.
The upper section is so joined to the lower section that direct application of heat to the lower section is prevented and is so secured that it may be readily removed for replace: "ment either to obtain a pallet having sides of different height or to replace the to section after it hasbecome worn or damage 1 The invention also consists in certain new and original features of construction and and claimed.
Although the novelfeatureswhich are be-- parts hereinafter set forth objects and advantages, the mode of its operation and manner of its organization may be better understood by referring to the following description taken in connection withthe accompanying drawings forming a part thereof, in which Fig. 1 is a longitudinal section of a portion of a sintering machine showing the arrangement of the pallets;
Fig. 2 is a transverse section thereof; and
Fig. 3 is an enlarged detail showing the removable pallet side.
Like reference characters denote like parts in the several figures of the drawings.
In the following description and in the claims parts will be identified by specific names for convenience, but they are intended to be as generic in their application to similar parts as the art will permit.
Referring to the drawings more in detail the invention is shown as ap lied to a sinter-' ing machine having a plura ity of pallets 10 which are movable on track 11 over a-suction box 13 in a manner well known in the art. Said pallets are adapted to pass under a hopper 14 by which a charge of material is applied thereto and is caused to spread in an even layer therein and are driven by a suitable driving wheel 15.
Each of the pallets comprise a main casting 20 having a shoulder 21 in which grate members 22 are seated and having projections 23 to which wheels 24 are secured. Said castings are provided with u standing side portions '25 carrying s'epara 1e mems5 bers 26. Members 26 are formed separate from main casting 20 and are provided with depending flanges 30 which are adapted to engage flanges 31 formed on casting 20 to which they are secured. Members 26 are of a height which permits them to pass in the v usual manner through the sintering machine and preferably extendflush withthe surface of the charge. I
The above described arran ement is such that side pieces 26 may be rea dily applied to or removed from'casting 20' whenever 't is desired to treat beds of material having ifferent de ths so that the total hei ht of the sides of t e pallet is always cause to correentirely across said to spond to the depth of the bed under treatment. Furthermore, the top edges of the side members become burned and otherwise damaged by the excessive heat which is encountered and require replacement more frequently than the remainder of the pallet. This invention permits such replacement to be readily made without discarding the entire pallet. The replacement of side members is a simple operation and may take place while the machine is operating and before the pallets reach the hopper.
The side pieces 26 and the sides 25 of casting 20 have been shown as provided with mortised joints whereby a rigid engagement between the members is obtained. This is shown by way of illustration only, and it is obvious that other types of joints could be employed for obtaining the desired result.
The arrangement above described is such that the entire top of the main castin 20 is shielded by the side member 26 where y the direct application of heat thereto is prevented. Furthermore, the inside of side members 25 is covered by the bed of material being treated and shields that portion of the casting from the sintering heat. The entire side and top of casting 20 is accordingly shielded and the portion of the pallet which deteriorates most rapidly may be replaced independently of'the remainder of the pallet.
While certain novel features of the invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the inven-- tion.
What is claimed is:
1. A pallet comprising a main casting having upstanding flanges and separable side members secured thereto, said side members having depending flanges adapted to engage said upstanding flanges, said separable members extending entirely across the top of said upstanding flanges for shielding the same from direct heat.
2. A pallet comprising a main casting having side members formed thereon'of a height less than the thickness of the bed normally treated in said pallet and additional side members mounted on the top surface of said first mentioned side members and extending surface, said additional members being su stantially flush with the top of the bed of material being treated and means for releasably securing said additional members. to said first mentioned side members whereby they may be replaced for treating beds of different thicknesses or to renew worn surfaces.
3. A pallet comprising a main casting having side members formed thereon of a height less than the thickness of the bed being treated and additional side members mounted on the top surface of said first side members and being substantially the same thickness thereof and covering the entire area of said top surface and extending upwardly substantially flush with said bed, said additional members serving to shield said first mentioned side members from direct application of heat and being readily replaceable for purposes of substitution or renewal.
4. A pallet comprising a main casting having upstanding side flanges formed thereon, replaceable side members having/depending flanges adapted to engage said first mentioned flanges and threaded members extending through said flanges for maintaining said replaceable members in position.
5. A pallet comprising a main casting having upstanding side flanges formed thereon, replaceable side members having depending flanges to engage said first mentioned flanges, means extending through said flanges for securing said detachable members in position, said members extending entirely across the top of said upstanding flanges and shielding the same from direct heat.
In testimony whereof I have hereunto set my hand.
REED W. HYDE.
