.SPECIFICATION forming part of Letters Patent No. lr\'5?,101, dated Aug-ust 9, 1904,

Application led March 22,1904y To all whom it may concern:

Be it known that I, ROBERT S. BROWN, a citizen of the United States of America, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Stock- Racks, of which the following is a specification.

This invention relates to racks for holding Io stock, such as bars of steel or other material,

and has for its object the provision of improvements in the construction of the rack whereby the weight of the load will be sustained without danger of collapse of the I5 structure and the stock will be held in position for ready removal without laborious longitudinal or end hauling'.

Afurther object of the invention is the pr0- vision of a rack the elements of which are composed of materials having different powers of resistance-for instance, steel and cast iron-the former being strong and reliable to resist combined bendingI and tensile stresses and the latter having twice the crushing strength of steel to sustain the compression due to the weight of the stock. Having these results in View, the columns of the rack are preferably composed of cast-iron sections and the stock-supports or hooks and the tensionbolts of steel, although the invention is not limited to these specific materials.

A further object of the invention is the provision of a stock-rack involving in its construction the unit system, so that said rack may readily be either enlarged or reduced in size in accordance with requirements.

A further object of the invention is the provision of a knockdown rack composed of united sections and detachable stock-sup ports.

A further object of the invention is the provision of stoclesupports or hooks of pccnliar construction.

Other objects of the invention will be hereinafter set forth.

In the accompanying drawings, Figure l is a perspective view of one form of the improved Serial No. 199,4L95. (No model.)

stock-rack. Fig. 2 is a perspective View of one of the stock-supports or double hooks shown in Fig. 1. Fig. 3 is a section on line 3 3 of Fig. it. Fig. +L is a side view of a wall- 50 rack embodying the :features of my invention. Fig. 5 is a side elevetion of one of the sections or distance-pieces of the rack. Fig.

6 is a plan view, and Fig. 7 a front view thereof. Fig. 8 is aview, partially in section 55 and partially in elevation, of a portion of the tray employed with the improved rack; and Fig. 9 is a section on line E) 9 of Fig. t.

Like numerals designate similar parts throughout the several views.

Referring to the drawings, the numeral 5 designates the columns or posts of the rack, each being composed of a number of sections 6, technically known as distance-pieces. These sections sustain the weight of the load and are consequently made of cast-iron or other material which will resist crushing strains. Each of the sections 6` constitutes a unit of the column 5, and each has front and rear flanges 7, united by a web 8, preferably perforated at 9 to afford lightness and also to provide an arch. At its upper end cach section is provided with a head 10, having perforated ears I0' and depending bosses 102, also perforated 'to register with the perforations 75 of the ears, said head beingl slotted at 1I, as shown in Figs. 6 and 7, fora purpose herein after stated. At its lower extremity each section is provided with a liat base 12, having ears and bosses 13 13', respectively, hav- SO ing perforations in alinement with the ears and bosses IO l()2 of head l0.

Designated by 14 are the stock-supports or hooks of the rack, which are preferably formed of steel of angle-iron shape, as shown by the 'l cross-seetion thereof in Fig. 3, although other forms of structural steel may be employed. In the form .represented in Figs. l and 2 cach stock-support is bent to provide a straight central portion le and upwardly-defiected ends la, thereby producing inclined bearingsurfaces or flanges l5 for the reception of the stock. Each end of the depending' ange of the stock-support is cut away at 16, and the top surface thereof is bent upward to form hooks 17, which will prevent dislodgment of the bars or other stock.

Bases 18, preferably of cast-iron to resist crushing stress, bear the weight of the columns 5, and each base has a short vertical pedestal 19 and strengthening ribs or iianges` 20, and it is also provided with a pair of perforated ears and bosses 21, for a purpose hereinafter stated. Short chambered projections 22 rise from the base-plates, and said projections receive lugs or pins 28, (see Fig.

8,) depending from a tray 24, uniting the baseplates of the columns, said traysconstituting convenient receptacles for short pieces, odds and ends, &c., not long enough to extend from one post 5 to another. Tension-bolts 25, of steel, are passed through the perforated ears and bosses of the sections 6 and base 18, and a cap 26, having ears and bosses 26', receives the upper ends of the bolts. Nuts 27 applied to the ends of the bolts serve to clamp the parts together, as illustrated in Figs. 1 and 4.

In the form represented in Figs. 1 and 2 the steel stock-supports are double and project from each side of the column 5; but in that illustrated in Fig. 4 single hooks 28 ofl the same construction are shown, and these hooks are prevented from longitudinal displacement by pins inserted in openings 28/ thereof.

As will be observed, the stock-

supports

14 and 28 are of gradual sizes, the lower one being longer than that just above it, and so on, gradually decreasing in length until the upper one is reached, which is the shortest of all. In virtue of this construction the weight of the load borne by the supports is proportioned to great advantage. In other words, the greatest load will be sustained by the lower stock-supports and less load by those above it, thus progressively decreasing the load sustained by each set of supports until the top is reached. Furthermore, this graduation in the sizes of the stock-supports materially facilitates the removal of the stock vertically when the usual hoist and runway service is employed.

In assembling the parts of the improved stock-rack the bases 18 are placed the desired distance apart--for instance, six feet-and the lowermost sections or units 6 are superimposed 'upon the short pillars 19. The lower repeated until all of the sections are in place to constitute the columns. Then the bolts 25 are inserted in the alined apertures of the sections, the caps 26 are placed upon the upper units, and the nuts 27 are .screwed home firmly to unite the parts of the rack. When the trays or pans24 are employed, their pins or lugs 28 are inserted in the sockets of the short posts 22, rising from bases 18, and the rack is then complete in either form represented.

W'hether employed as a double or a single rack the mode of assemblage is precisely the same, and either rack may be built up to the height desired, with its columns set at any required distance apart, or can readily be disassembled or knocked down for transportation purposes. Interchangeable trays of differentlengths may be provided, so that the columns may be spaced apart, as required, and as the unit plan prevails in the entire structure the rack may be made of any length and of any height to accommodate it to all requirements.

In practice it has been found that when the columns are spaced six feet apart the six graduated double stock-supports carried by each column are of proper proportions to sustain the weight of at least seven tons of merchant bars of machinery steel eighteen feet long without danger of overloading.k

Different sizes o'f stock may be segregated and placed .on the supports, one size on the lower set of supports, another size on the set above, and so on, thus avoiding veXatious loss of time and its consequent expense in searching out the size required.

From practical experience it is found that the entire space between two stock-supports may be filled Without overloading and that owing to the physical character of the material of which said stock-supports are composed they would bend or spring, and warning would thus be given by them before collapse.

Changes may be made in the form and proportions of the various parts without departure from the invention, which is not limited to the details shown. Furthermore, the in- 'vention is not limited to the precise materials specified, for other materials havingthe same or substantially the same qualities may be employed, if desired.
