Be it known that I; Gnomes A Burnt; a

citizen 'o'f'ihe United States, residing Springfield; in the county of Sangamon and State Illinois have invented a new and useful VVrought-ldetal Socket for L egsor Standards or the like, of whichithe following is a-specificationQ p, y)

The invention relates to sockets such as are used on structures such as trestles', cars, trucks, etc, to connect legs or standards, or the like, with; the several structures.

The purposes'of the invention are pro;

vide a socket, preferably of wrought netah combination lightness and rigidity and p l q ek nd. e sy F ee n 2 t e structure on which itis sed to admit of n ng. l ss or s andard la ally outward relative to the structure, andfalso inclining them outwardly inflthe direction of the lengthof the structure to pre'vide a socket of such; form that to forma number of sockets may be punched, andcut u s n from *1 sin le, meta 9.3 a plate of predetermined ,wiplth and indeiinite e h, with ry smal te 0t Ineteriab thereby minimizing the cost of construction; and to provide improved structural details as will hereinafter appear.

N IN, I n he biv slbyit s mean lll n trated in the accompanying drawing ,in which F u I s a de elev tipnef a typical structureg in the present i stan'ce: a carpentersv trestle, equippe'd with metal sockets embodying my invention; Fig Z is an enL rged view of one detached socketembodying inventiop yiewed tro m below and ei pv rcl' iiite ier sl s Fig. 3 is vertical section through the same socket, takenon the line 3 of Fig 2;

Fig. 4 is a vertical section through the same socket on the liners- 4: ogf ig; 2;

Fig. 5 is a vertical section taken on the line 5-5 of Fig. 1; I

Fig. 6 is a diagram showing a top View of a metal plate or bar from which two blanks, each suitable for forming a socket,

have been cut; and

Fig. 7 is a vertical section through one blank taken on the line 7-7 of Fig. 6.

Similar numerals refer to similar parts throughout all the views.

The sockets will preferably be made from a fiat metal plate or bar A of any convenient length and of width corresponding to the length of the sockets which are to be made,

se'ach other.

andof suitable thickness, varying according to the required rigidity and strengthof the sockets. I havelfound by experiment thata bar of No. 12 gauge is suflicient for sturdy trestles, such as are commonly used by plasterers and bricklayers, and thinner metal may be used for sockets on ordinary carpenters trestles. v A In laying out tie work transversely oblique lineso a, indicated in Fig, 6, will bedrawn on the bar to divide itsjentire length into a series of spaces,the extreme length of each space being equal to-the e treme length of the socket which is to be i A m't; The centers .of a series of central gauge holes 9, and the centers of a series or bolt 110168 .1 w a l he e a edin es -m gh med an 111116 e ending the u lengt of the bar, and the bar will; then be cut along thfe line pa n, to divide it intoa series' ofi blanks 12. The holes 9 and lO wil l preferably be punched simultaneously with the cutting ii,

o t p iv ban i, he bl s a eal alike. b Each has a cen tral gauge hole 9, c nd two bolts holes 10, all in line with r 0 m 3 3 1 :ll ti l; Q Q hQ nk will be bentdownward along the dotted lines. 3 PW? s ang he ot d' i e n a d alo e h dot-t d li 15, d ou w r a one the dotted line I6. Here it to be noted t as enem tween-a e. l n 316 and as edge 1 of the blank is considerably greater than t an l t it e e, lat tet edge' l?" of the blank The purpose of this angular d e e ce .wi 'r e esc ater-M In case the sockets are used on atrlestle;

it: is usual to spread the legstlaterally as how in gand i s oft n es r b e tie inverted and used with equal advantage to connect upwardly-extending spreading standards on a car, a truck frame, or a platform or other stationary structure.

Referring to Figs. 2, 3 and 4 it will be seen that the outer wall of the central part, which I call the box, the end walls 21 and 21, the wings 22 and 23, the stop member 18 ofi set from the wing 22, and the stop member 19 offset from the wing 23; are all formed from a single blank, and the structure is symmetrical except that the stop 19 is longer than the stop 18, and is offset from the edge 25 of the end wall 21, a greater distance than the stop 18 is offset from the edge 2% of the end wall 21.

The sockets placed on the trestle beam 26 are in pairs, right and left; the pair of right hand sockets incline downwardly towards the left to cause the legs held in the respective boxes to incline towards the right, in the direction of the length of the beam; and the pair of left hand sockets to incline downwardly towards the right to cause the legs held in the respective boxes to incline downwardly towards the left, in the direction of the length of the beam.

The boxes are tapered in order that when the tapered parts of the legs are in the boxes and their inclined faces are in contact with the sides of the beam 26, the legs will be inclined downwardly and laterally, right and left as shown in Fig. 5.

From the foregoing it is clear that the disposal of the stops in different planes one above the other adapts them for the described inclination of the sockets relative to the horiontal underside of the beam 26; it is also clear that by reason of extending the bend in the direction of the length of the wing 23, the necessary increased length of the stop is attained without increasing the width of the blank from which the socket is formed. This expedient simplifies the construction, increases the strength of the stop 19, and results in a considerable saving of material.

The bevel of the boxes of the sockets may obviously be varied to suit difierent structures, without departure from my invention.

The blanks for light sockets may be sheared from thin metal sheets of suitable width, and may be formed by hand on suitable blocks held in a vice. Heavier sockets may be formed by power presses equipped with shears, punches and suitable dies. Means for forming the sockets are not part of the present invention, and, therefore, are not shown or described.

To attach a pair of sockets on the beam 26 of a trestle, the sockets will be placed one on each side of the beam, and the stops 18 and 19 of each beam will be held firmly against the underside of the beam and centers corresponding to the respective holes 10 will be marked on both sides of the beam; bolt holes will then be bored or drilled at the respective marked centers; bolts 28 will then be inserted in the holes through both sockets and the holes through the beam, and the nuts 29 will be screwed on the bolts to connect the parts securely.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A wrought metal socket-member for legs, or standards or the like, comprising a tapered box having end walls parallel to each other, Wings integral with an ex tending outwardly from the respective end walls, and stops of unequal length integral with the respective Wings, and formed by bending one'terminal part of each wing at an angle relative to the wing and adapted to hold the socket-member in inclined relation to the structure with which it is connected.

2. A wrought metal socket-member of the class described, formed from a fiat blank having two edges parallel to each other and two inclined edges converging towards each other, and bent to form a tapered box having end walls parallel to each other; wings extending outwardly from said re spective end walls and stops of unequal length at one terminal. of the respective wings and adapted to hold the socket-member in inclined relation to a structure with 9 which it is connected.

In witness whereof I have hereunto signed my name at Springfield, Illinois, this 20th day of February, A. D. 1925.

GEORGE A. BRYAN.
