BRICK-DRYING RACK.

Specification of Letters Patent.

Patented Jury e, i909.

Application filed March 20, 1908. Serial No. 422,355.

To all 'whom it may concern:

Beit known that I, EDWARD H. CALLAWAY, a citizen of the United States of America, and a resident of l/Vestfield, county of Union, and State of New Jersey, haveinvented certain new and useful Improvements in Brick- Drying Racks, of which the following is a specification.

My invention refers to a drying rack intended for various purposes, but more especially for the drying of bricks, in connection with brick manufacture, or the drying of other articles made of clay of various kinds.

The object of the invention is to simplify and perfect the means for supporting the drying shelves, which latter consist each of a series of steam pi es on which the bricks or other articles to Fe dried are placed. And, the invention. therefore consists essentially in the construction, arrangement and combination of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawing, illustrating my invention, Figure 1 is a side elevation of one of the pipe-supporting standards. Fig. 2 is a side view of the same. Fig. 3 is a vertical section. Fig. 4 is an enlarged partial side elevation showing several of the pipe shelves in section, and indicating the means for retaining the latter in position in the standards. Fig. 5 is a top plan view of the parts shown in Fig. 4. Fig. 6 is an enlarged sectional detail on the line r a; of Fig. 4, the bolt being shown in side view. Fig'. 7 is an enlarged sectional detail on the line g/ y of Fig. 4, the steam pipe being shown in side view.

Like characters of reference designate like parts throughout all the different figures of the drawing.

A drying rack of the kind contemplated by my present invention consists of a suitable number of uprights or standards, `one which is designated 1 in Fig. 1, and also of a suitable number of horizontal shelves, as it were, composed of a plurality of steam pipes, on. which pipes or shelves the bricks or other articles to be dried are placed. A row of these pipes is shown in the drawing designated. 2, 2, 2, 2. Another row 2a, 2a, 222% another row 2b, 2b, 2b, 2b, another, 20, 2G, 2c, 20. Of course there may be any number of these rows,

perforations in the p is designated thus by tightening the nut 14 on the bolt 12 each row mak ing up a brick shelf and any number of pipes in each row, a wide latitude being permitted in these respects.

rllhe standards 1, of which there may be any number, each consists of a series of horizontal crosspieces 3 connected at the ends to uprights 4 5 or, in other words, each standard 1s cast in a single piece having the horizontal cross-pieces 3 which are integral with the upright end oortions 4, said end portions 4 being preferably formed as angle-bars with the wide parts 5 at right angles to the vertical surfaces of the standards, as shown in Figs. 1 and 2. The horizontal cross-pieces 3 are provided with a number of semi-circular recesses or notches 6 to receive the pipes 2, 2, etc., and there are spaces 7 intervening between the horizontal pieces 3, said. spaces serving not only to contain the steam pipes but also the means for retaining the steam pipes in place.

The various spaces 7 between the horizon tal notched cross-pieces 3 are occupied by pipe-retaining stri s 8 which correspond in shape and size to t ie s )aces 7. Said strips S are furthermore provi( ed with semi-circular recesses or notches 9 which lie opposite to the semi-circular recesses 6 in the cross-pieces 3, and form in conjunction with said recesses (i circular openings to receive the horizontal steam pi ies, said steam pi es being thus completely encircled. and heh. firmly in place with the exception of a slight `looseness which may be found desirable in order to allow said pipes to be capable of such longitudinal eX- pansion. as may be incidental to the heating and cooling of the same. Further, the re taining pieces 8 are formed cach with an encircling flange 10 which lies closely against one side of the standard 1, as indicated in Figs. 6 and 7. The strips 8 are kept in place within the recesses 7 by means of the flanges 1.0, and also by the short vertical plates 1 1 on the opposite side of the pieces S from the fianges 10, said plates 1]. overlapping the edges of the horizontal cross-pieces 3, as seen in Fig. 4. Bolts 12 pass through erforations 13 in the retaining )ieces 8, anc also other late 1.1, and are provided with a nut 14 and a head 1.5, said head 15 being on one side of the strip 8, while the nut 14 is on the opposite side of the plate 1] 5 and the strip Sand plate 1.1 maybe tightly locked together, which will result in locking the strip 8 very 'firmly within. the recess 8 that receives it 5 and the other result of firmly securing the neces 8 within. their respective recesses 7 wi l be that the pipes constituting the several drying shelves will be securely held between the rigid integral cross-pieces and the removable retainingI strips 5l within the circular openings made up ol' the semicircular recesses 6 and the semi-circular recesses as already clearly pointed out.

The retaining pieces S and the clamping plates 1 1. with their bolts and adjustable nuts are employed in connection with all ot the cross-pieces 3 except the top one ofthe standard, where the construction is preferably somewhat diil'erent as is indicated in the upper part of the staudaril represented in Fig. 4. 'lhere a much wider retaining-plate 1.6 is used, the same having at one end an angular recess at 1.7 which. receives a correspondingly angular form 18 on the standard 1, this angularity of the connection being for the purpose of assisting to hold the plate 16 in position. rFhe plate 1G, like the strips 8, is furnished with a flange running entirely around it and fitting against one side of the standard 1; but .in lieu of the plates 1.1, a single long horizontal bar 19 which overlaps the face of the standard 1 at the ends of the strip 16, instead of above and below as in the case of plates 11, since there will be no bearing for a plate above in this instance and the bolts 1.2 headed, as stated, and provided With adjustable nuts 14, are employed in connection with the bar 19 passing through holes therein, and also in the plate 1.6, similarly to the arrangement with the strips S and plates 11.

The provision of means, consisting of a notched strip inserted within. the recess which receives the pipe belonging to any one shelf, is found in practice to be quite desirable, for if the spaces 7 were left open and unoccupied by such a retaining piece, the pipes would be apt to lift themselves more or less completely out of the lower recesses G, and in thus becoming disturbed in their position, cause the shelves to warp and twist, which would be detrimental to the drying process, as well as injurious to the bricks. But by employing the strips 8, the pipes are securely held. in the standards, and tl e latter are thus capable of sustaining the pipe shelves in the proper position of horizontality, thereby making them eilicient and serviceable in carrying out the purpose of the apparatus. A rack constructed in this manner, with standards at proper intervals in the length of the pipes, and with shelves consisting of pipes, which shelves are properly spaced apart and each consists of the requisite number of pipes, will be found to provide a unique and very useful forni of (ilrying rack productive of the very best results.

By inserting plates as 8 in all of the spaces 7 between the horizontal ribs 3, and thus lilling all the openings in the standard., l provide a standard which is solid from top to bottom; that is to say, when the pipes are arranged in their supporting recesses with the plates 8 in position, the standard in combination with the pipes presents a solid combination from top to bottom (excepting the slight play permitted the pipes in expanding). lflence it is possible to construct a rack such that when these solid standards are employed there will be sections or chambers partitioned o'll from. each other by these standards, and the heating may thereby be controlled and utilized differently from what it can in those eases where it has free passage throughout the entire length of the drier. This subdivision of the drier permits many advantages to be gained. which will be selfevident in the operation, and need not be set forth here withv greater detail.

Many changes in the precise form and arrangement of the various parts may be made without departing from the essential features of the invention, as they will be hereinafter set forth in the claims.

ll'aving thus described my invention, what l claim as new and desire to secure by Letters Patent, is:

1. The combination with heating pipes, of

a supporting standard therefor, consisting of f a series of horizontal cross pieces arranged one above another and having curved notches therein for receiving the pipes, and retaining strips ilitting into the spaces between said horizontal cross pieces and having corresponding curved notches engaging the pipes, together with means separate from the pipes for holding the retaining strips in place.

2. The combination with .horizontal rows of heating pipes, of a supporting standard therefor having horizontal cross pieces arranged one above another and intended to receive the pipes, and strips fitting between said cross pieces and engaging the pipes, said strips being Aflanged, plates on the opposite side of the standard from the flanged side of the strip, and bolts for connecting the strips and plates together.

8. The combination with heating pipes, of a standard for supporting the same, having horizontal bars arranged one above another and provided with a series of curved notches for holding the pipes, means for keeping the pipes in position in said notches consisting of flanged pieces li tting into the spaces between the notched bars, and locking means for keeping the latter in position.

4. .in a drying mechanism, the combination with heating pipes, of a standard. supporting said pipes, consisting of horizontal bars arranged one above another and united at the ends, said bars being suitably spaced apart a nd provided with notches for receiving the pipes, and retaining strips fitting tightly into the spaces between the said bars and entirely filling said spaces With the exception of the openings that receive the pipes, said strips being provided With notches engaging the pipes, said pipes fitting closely in the openings that receive them, and clamping means including bolts and plates for keeping the strips in position.

5. In a drying mechanism, the combination with heating pipes, of standards supp orting the same, consisting essentially of liorizontal cross ieces arranged one above another and having curved notches therein, and retaining strips fitting closelT into the spaces between said horizontal cross pieces and having also corresponding curved notches engaging the pipes, said retaining strips being flanged to engage the sides ofthe standards.

6. ln a brick dryin rack, the combination with heating pipes, o a supporting standard having horizontal cross pieces arranged one above another and provided with curved notches therein for receiving and holding the pipes, removable retaining plates filling the recesses above the pipes, and clamping means separate from the pipes for holding the retaining strips in place.

7. The combination with heating pipes, of a supporting standard therefor, consisting of a series of notched cross pieces arranged one above another, a series of retaining strips iilling the spaces above the ipes and between the cross pieces, in order t at said pipes may be held in position With enough play to per- Init of eX ansion, and means separate from the ipes or holding the plates in position.
