N'ILSY OLSON, OF SUPERIOR, WISCONSIN.

,BRICK-PROTECTOR.

SPEQIFICATION forming part of Letters Patent No. 502,987, dated August 8, 1893.

Application iiled January 28, 1893. Serial No. 460,104. (No model.)

To all whom it may concern-3 Be it known that LNLS OLSON, of Superior, in the county of Douglas and State of Wisconsin, have inventedV a new and Improved Brick-Protector, of which the following is a full, clear, and exact description.

My invention relates to improvements in brick protectors of the kind described in Letters Patent of the United States No. 432,430, dated July 15, 1890; and the objectof my invention is to improve the construction shown in said patent and provide sheds or protectors' with folding wings or roofs; to arrange gutters so that the water shed by the wings or roofs will be carried away to provide means for covering the alleys between groups of pro-v tectors; to provide stops which will prevent the wings from being raised too high and consequently broken, and to provide means for raising theseveral wings eitherseparately or simultaneously, as described; to the end that the yard may be always kept dry and work proceededvwith even though it may rain.

My invention consists in certain features of construction and combinations of parts, as will be hereinafter described and claimed.

Reference isto be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a broken central longitudinal section of a system of protectors embodying my invention. Fig. 2 is avertical section on the line 2--2 in Fig. 1,showing in section, the

roof for covering an alley between two grou ps v of protectors, and showing the protectors proper in end elevation. Fig. 3 is a cross Section on the line 3-3 in Fig. 1.' Fig. tisa detail cross section, showing. the manner in which the hoisting rope is secured; and showing also in detail the manner in which the wings or roofsare pivoted. Fig. 5 is a detail sectional view of a 4portion of the hoisting mechanism and the hangers which limit the upward movement of the sheave blocks and wings; and Fig. 6 is a detail sectional plan of the hoisting mechanism on the line 6;-6 in Fig. 1.

The protectors illustrated in the drawings have the same general characteristics as those Shown in my former patent alluded to, each protector comprising base plates 10, vertical posts 1l erected on the base plates and provided with braces l2, and oppositely swinging arms 13 pivoted near the tops of the posts and adapted to swing vertically', wings 14 secured to the arms and formed of overlapping boards, the cap 15 to'cover the joint between the opposing wings, and the inwardly and downwardly extending links 16, which connect opposite arms 13 and which are pivotally connected together at their lower ends and are also pivoted to the sliding sheaves as hereinafter described.

The above construction is substantially like that shown in my former patent and is notv claimed as a part of this invention.

The wings`14 have at Vtheirlower and outer edges, gutters 17, which are carried by the arms 13 and which receive and carry off the water which iows from the wings. To guard against any leakage between the adjacent and parallel protectors, the gutters 17-which come together, as shown in Fig. 3, are covered kby anv inverted gutter or shield 13 which is'supp'orted by hangers 19, they latter being carried by cross braces 2O extending from one cap 15 to the opposite one." Extending longitudinally through each shed; that is, be`

neath each cap 15, is a brace or reach pole 21 to which at intervals are secured depending hangers 22, and the hoisting-rope of each protector extends longitudinally through slots in the posts 1l and over guide pulleys 2i in said slots, and also 'between the hangers 22.

The hoisting rope 23 extends over guide pulleys 25in the hangers'22, thence downward around sheave pulleys 26 in the sheave blocks 27, and the ropes are then extended upward and secured, as shown at 2S, to the hangers.

There is avropeffor each sheave block 27 and, as the sheave blocks are pivotally connected with the links 16 of the swinging wings, it will be seen that when the ropes 23 are pulled in one direction, the'Y sheave blocks will beV raised and the wings also raised,while if the ropes are pulled in the opposite direction the blocks and wings will be lowered. The ropes 23 are at one end made fast to a pulley block 29, which is arranged near one of the ends posts 11, aud extending around the pulley in this block is a rope 30 which extends outward and downward over a pul- IOO ley 31 in the post, and is made fast toa crank windlass 3la which is provided with a suitable pawl 32 and ratchet wheel 32 to prevent it from turning in the wrong direction. Any suitable Windlass may, however, be used for operating the rope. The opposite member of the rope 30 passes outward and downward over a pulley 33 in the post, and thence downward beneath the base plate 10 and is secured to a cable 34 held to move in a guide or conduit 34 which extends at right angles to the protector. The rope 30 of each protector or shed is connected with the rope 34 and with the windlass in the manner specified and as illustrated in Figs. 1 and 2, and the cable 34 is adapted to be operated by a suitable engine. It will be seen then that if one pairof wings 14 is to be raised, it may be done by simply turning the windlass 31, as the winding of the rope 30 on said windlass pulls the block 29 toward the end post 11 and the ropes 23 are thus pulled so as to lift the sheave blocks 27, the links 16, and the wings 14. If, however, a whole series of wings are to be raised, the rope or cable 34 is wound by the engine so that the ropes 30 are simultaneously pulled and all the wings raised in the manner described.

lVhen the `wings are to be collapsed, the pawls 32 are released and the ropes 23 pulled in the opposite direction by means of ropes 35 which are secured to the ropes 23 and which extend outward through slots 35a in the post 11, at one end of the shed or protector, although as a general thing the wings will drop of their own weight.

It is customary in a brick yard to arrange the protectors or sheds in groups or series, and in Fig. 1 I have shown two such groups, the alley between which is covered by the roof 36 which is supported upon a framework consisting of rafters 3G and cross timbers 36h, the cross timbers being supported on the caps l5 of the opposite protectors.

From the foregoing description it will be readily seen that any one of said protectors may be operated to either raise or lower the wings, that ifA desired the entire series may be simultaneously operated, and that the whole yard may be completely covered and the water carried away so that the bricks beneath the protectors are kept from injury.

It will be seen that the water, which is discharged by the roof 36, is caught by the adjacent wings 14 and by them discharged into the gutters. It will be further observed that when either pair of wings is raised or all are simultaneously raised, the sheave blocks 27 will rise and their upward movements will be limited by the hangers 22 against which the sheave blocks strike, so that the upward movement of the wings is thus limited and the apparatus is prevented from being broken.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with the protector sup ports, the swinging wings pivoted on the supports, and the vertically movable sheaves pivotally connected with the wings,.of stops or hangers arranged to limit the upward movements of the sheave blocks and consequently of the wings, substantially as described.

2. In a brick protector, the combination with the series of protectors or sheds, each protector comprising supporting posts, oppositely arranged and vertically swinging wings, vertically movable sheave blocks, and links pivoted to the sheave blocks and to the wings, of horizontally movable pulley blocks arranged near the ends of the protectors, hoisting ropes connecting the pulley blocks .with the sheave blocks so as to operate the same, awindlass arranged at each protector,a winding cable extending adjacent to the protectors, and operating ropes secured to each wind lass and to the cable extending around the pulleys of the pulley blocks, substantially as described.

3. The combination with the parallel protectors having vertically swinging wings, of gutters secured to the free edges of adjacent wings, and a shield supported over the adjacent edges ot` the gutters, substantially as described.

4. The combination with the series of protectors comprising vertical posts and wings pivoted thereon, said protectors being arranged in groups, so as to leave an alley between each two groups of a removable roof extending from one group of lprotectors to the other over the said alley and arranged ,to discharge upon the protector wings, substantially as described.

NILS OLSON.
