- HERBERT E. SCI-ILESINGER, F YPSILAN-TI, MICHIGA l i ADJUSTABLE HANGER FOR BEAMS AND JOISTS Application led September 18, 1929. Serial No, 393,362.

It is well known in the building tradeV lift thatlumber is marketed in lengths of an evenv number of feet, and that there is usually a considerable. loss through ,wastage on beams and joists.l For example if oists 8 6 are required for a Certain buildingconstruc- 72,0, tion, it is necessary to buy 10 0 lengths and cut them down to 8 6,

The primary object therefore of the presf ent invention is to provide an adjustable hanger which While providing a better support lfor joists is also adapted to retain the j oists in an upright position without nailing or cross-bridging;the eXtensible feature of the hanger permitting the use of joists of various lengths of sp an. Thus in a span 8 6", and 8 0 j oist could be used with the present hanger instead ofl a l0 ft. piece as vformerly required, thereby resulting in the saving of in lumber alone. Y 1

In temporary rbuilding construction, such as centering floors, 4this device has particular advantages.` j,

In this class of construction, it is necessary to erect and remove the j oists as readilyV 40 and quickly as possible ;-the lumber being t i frequently Vusedagain and again on different floors during the erection of a high building.' Therefore by the employment of this device, it is possibleto use the joists vmany times over various spans, without. cutting or splicing,resulting f in a large saving in time, lumber and material'.

A very considerable advantage gained by the use of this invention in the class of construction just referred' to, is that the joist im may be held in an upright position without other securing or bracing means, and by its use the ends of the joists are less liable to crack or split, as the member is handled and brought into use againl and again through-l out the job.

A further object of the invention is to provide a device whichis simple and ineXpensive to .construct and one practicallyA indestructible.

A further object of the invention is to pro-` 6o vide a device which is not only adapted for wooden beams or joists, but is equally fit for use with steel beams or other likebuilding material. V-

With the foregoing and other objectsfin Off;

View which will appear as the description proceeds, the invention further resides in the` combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that 7,0 changes may be made in the precise vembodii ment of the invention herein disclosed without departing from the spirit of the same.

In the drawings accompanying this speci-1 fication: f

Figure l is a perspective View of the hang-v er attached to the end of a joists-a, fragment of the latter being shown. Figure 2is a fragmentary perspectiveview ofthe hangerA with parts broken away to more clearly disclose lits construction ;--as viwed'from the end opposite that presented in Figure 1.

Figure 3 is a'fragm'entary side elevation of a joist, the ends' of which aresecured in hangers resting on the wall of a building.

Figure is a cross-sectional view taken on or about line 4-4 of Figure 1. 1

Figure is a perspective view of a modii- 90 cation of the hanger showing the fragmentary end of a joist supported thereby. Figure 6 isa cross-sectional view through the device taken onor about'y line 6-6' of Figure 5. j Figure 7 is a perspective view of'another modification of the hanger, showing the joist supporting members constructed of opposingl channel members in place ofthe vangle-iron lo shown in Figurel.

Referring now to the letters of reference placed upon the drawings:

A, A are two parallel L-shap-ed members of suitable length maintained in spaced relation by plates B, B, spot welded to the upper horizontal flanges of said members.

C, Care L-shaped members secured in cori respondingly spaced relation by plates D, D, D1, preferably spot-welded thereto. The members C, however are bent at an angle (C1) midway of their length, whereby the major portion of the members C are spaced a relatively greater distance from the members A to receive the ends;v ofa joist E, than at the opposite end of the hanger,-which forms a foot portion adapted to rest upon the building wall F. f

G G are bolts located on opposite sides of the joist extending through the horizontal flanges of the members A and C whichA upon the adjustment of the nuts G1 draw together themembers-A and C, thereby securely clamping the j'oist between the plates B and D..

In the modification shown in Figures 5- and 6,' the lower angle members C', C, and their connecting plates D have been dispensed with, and in place of the'bolts G, shown in Fig'- ure I, U-shaped bolts supported in the horizontal flanges of the upper angle iron A are employed,-with a plate J, located between the joist and the loop of the bolt--see Figures 5 and 6.

To assist in maintaining the vertical wal-ls of the L-shaped members in proper spaced relation, U-shaped clip plates K are welded tothe flanges of the L-shaped `members-see Fi re- 5.

"-nF-igure 7 another modification is shown in' which opposing channel members L, L are held at one end in spaced relation by bolts M,M, extending through cross strips N, N attached to the channel members and to the brackets O, O,- attaehed to the other member;

v` the flanges of the channel members being preferably welded together, as at L? at the opposite end.

P indicates a foot plate welded to the underside of the lower channel member to provide a relatively broad support for the device on the wall of a building.

Having indicated the several parts by refer-` ence letters, the construction and method of employing the device will be readily underinserted in the hangers, the latter being adjusted in relation to the ends of the joists to provide a beam of the required longitudinal length ;-the nuts are then tightened, securing the joists in the hangers.

To admit of nailing a floor or other horizontal member to the joist, slots Q are provided in the upper supporting` member of the hanger for the passage of nails into the joist-see Figure 7 Having thus described my invention, what I claim is: Y y l.

l. A structural unit adapted to be adjustably mounted ona joist', whereby the span of the joist may be varied, said structural unit comprising a sleeve-like portion, adaptedto receive the joist, and also a bearing'portion,i of the! affording support above the plane lower edge of the joist. 1

2. A structural unit for supporting transiverse loads, comprising a truss-like 'portion telescopically engaged upon a beam portion,4 said truss-lilre portion having top and bot-- tom chord members, adapted to embrace Ysaid beam portion;l and means for securing-said edge of the joist is below the plane of the.

bearing portion; and means for engaging the' upper and lower members of the hanger to draw them toward each otherv to gripthe Joist. t. A structure as specified in claim 3 in combinationwith a plurality of transverse plates attached to the upper and lower members of the hanger.v

5. A structure as specified in. claim 3 in. combination with a transverse plate attached to the underside of the footing, to .provide a relatively broad supporting surface.

6. A .'oist supporting hanger adapted tofbe adjustably mounted upon the ends of a joist to lengthen the latter to lit spans of various: size, said joist supporting hanger compris# ing an upper pair and a lower pair of oppasing longitudinal members spacedv apart lat-v erally to embrace opposite sides of the joist, said upper and lower pairs oopposi'ngmembers being also spaced apart vertically in par, allel relation at one end to receive the ends of a joist, the. opposite end portion of. the lowerpair of longitudinal members being bent toward. the upper pair of members adjacent; said end portion, the immediateadjacent end,

portions being parallel lto the upper members to provide a bearing for the joist, adapted to rest upon a support, a plurality of transverse plates attached to, and overlapping respectively the walls of the. upper and lower members; and bolts tted with nuts eX- tending through the walls of the opposing members, whereby upon adjusting the nuts, said members may be drawn toward each other to grip and;i adjustably secure said hanger to the end of the joist.

7. A supporting hanger adapted to be adjustably mounted on the ends of a joist to lengthen the joist to `fit spans of varying size ;-said hanger comprising upper and lower opposing members spaced apart at one end to receive the end of the joistg-the opposite end of the lower member extending upwardly in relatively closer relation to the upper opposing member to form a bearing portion for the joist, adapted to rest upon a support, whereby the lower edge of the jost is below the plane of the bearing portion; and means for engaging the upper and lower members of the hanger to grip the joist.

In testimony whereof I sign this specification.

HERBERT E. SCHLESINGER.
