Svpecicaton of Letters Patent.

Application led February 21, 1914i Serial No. 820,095.

To all rwhom it may concern Be it known that I, CLEMENT L. F LYNN, a citizen of the United States, residing at Bellingham, in the county of Whatcom and devices hereinafter described and defined in the claims. 'A

The silo embodied in the several features of niy invention is illustrated in the accompanying drawings wherein like characters indicate likeparts throughout the several views. y

' Referring to the drawings: Figure 1 is a front elevation showing a portion of the improved silo but with the outer. panel-boards removed; Fig. 2 is a vertical section taken on the line x2 :v2 o-n Fig. 1, showing the Aouter panel-boards in position; Fig. 3 is a horizontal section taken on the line w3 x3 o n Fig. 1 and then the outer panels; Fig. 4 1s a fragmentary perspective of one of the posts or uprights; Fig. 5 is a perspective View of the preferred form ofpanel-board; and F ig.-6 is a complete horizontal section of the silo..

Referring to the drawings, 10 represents a foundation of concrete or other suitable material and is provided with a ledge or sill 11 upon which the silo-wall is supported. This wall is of a polygonal form in horizontal section and is provided with a frame comprised of upright members or posts 12 which are positioned at the respective angles of the wall, and horizontally disposed tiemembers or rods 18 which connect the adjacent posts with each other.

The posts or upright are constructed, each of a piece of timber having in each of its sides 13 and adjacent to its inner face 14, a recess 15 formed to the arc of a circle and extending the entire length of the post. Said recesses serve to house the ends 16 of horizontally disposed panel-boards 17, said ends being formed to the same curvatureas that of the recesses whereby close fitsr'nay be had between the post's and 'the panelboards when the latter are`arranged in various angular relations with respect to the posts, as indicated, for example, by the full- Y ton line positions, or by broken linesfA in Fig. 3, as may be required for different diameters of silos. These boards may -be made of uniform Widths or of what is conventionally known as random widths and are formed with matching top and bottom edges 17 and 17 2 which, by preference, are respectively of convex and concave forms, as shown in Fig. 5.

The adjacent posts of the wall, as above mentioned, are connected by coupling rods or bolts 18 which extend through holes 181 provided in the respective posts and are secured thereto against lateral displacement by means of nuts 19 and 20 engaging screw:v threads provided on the bolt-ends and in' juxtaposition with washers 191' andl 201 which, in turn, bearagainst the opposite sides ofthe posts. Said bolts are disposed in-seriesor groups which are designed to extend entirely around the wall.

Adjacent their outer faces, the posts 13 are provided with 'rabbets 21 to receive the ends of horizontally arranged boards 22 having tongue-and-groove connections with each other.

It is highly importantto note, that in this improved silo, the rods or bolts 18, 'with their double sets of nuts 19 and 20, applied as shown and described, not only serve'to hold the luprights 14 against separating movements in respect to each other, but also against approaching movements, in respect to each other. Otherwise stated, the doublenutted rods are, in fact, combined coupling and spacing rods which cooperate with the uprights 14 to make a self-sustaining skelefor an approximately circular silo, wherein all pairs of adjacentv uprights are coupled, together and spaced apart from each other to any desired predetermined distance, independently of all other pairsy of uprights in the entire series; and at thesame time, these combined coupling and spacing rods, taken collectively,v serve to tie or couple together all-the uprights of the entire series, and to space the same apart from Y arcs of a common circle.

The uprights are grooved, as described, on

l each other approximately on the chords fof'.y

their vertical' faces, thereby adapting the i pairs ofadjacent uprights to receive and seat the straight panel-boards 17 with freedom for a limited variation in the angular relation of the boards to the uprights; and

when" the panel-boards are thus in position, the elements above named complete a S110 which is approximatelyrof circular form..

. large importance yfor simplicity' of construction, shipment, and facility of erection. Any `pair of uprights can be placed proper working position and tied or coupled together and spaced apart to the desired predetermined distance, before the erection of any additional uprights, if so desired, and the panel-boards can be applied between the single pair of uprights, then additional uprights may be added and additional coupling and spacing rods be applied and panel-boards placed between the next adj acent pair, until the silo is completed; or additional pairs of uprights can be placed anywhere else around the commoncenter, asby different workmen, and the panel-boards be applied between the saine, thus enabling several sets of workmen to carry on the erection, simultaneously, from different points.

A These are matters of large importance in the building of silos. The said self-sustaining skeleton and the panel-boards 17, of course, constitute the silo proper, and after this is completed, the boards 22 are applied to their rabbeted seats 2l in the outwardly projecting portions of the posts 12,- and fsecured` thereto by screws or nails 26, thus affording an outer wall to the main silo withany air jacket space between the two.

What I claim is:

LA self-sustaining skeleton for an ap; l

proximately circular silo,.which3 skeleton comprisesa seriesof `uprights and a series of horizontally disposed combined-coupling and spacing rods serving to couple or tie together and to spacelapart all pairs of ad-l jacent uprights independently-of any other palr of the entire series of uprights, and also to couple together and space apartl all the l upriglits of the entire series approximately on the chords of arcs of la common:l circle,

substantially as described.`
