'Speci'fieationof Letters Patent Application filed February 15,1913.

Patented Novt25, 1913. Serial No. 748,601.

To all whom it may concern:

Be it known that 'I, FREDERICK MEIsTnR, a citizen of the UnitedSt'ates, residing in Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Floor-Supporting Structures of Theaters and the like, of which the following is such a full, clear, and exact description as will enableany one skilled in the art to which it appertains to make and use the same, reference being had to the -ac companying drawings, forming part of this specification.

My invention relates to the construction of floors for theaters, amphitheaters and the like, and it has reference more particularly to the fioor structures lying above the level of what is ordinarily known as the orchestra or auditorium.

.I have illustrated a type of mycinvention in the accompanying drawings, wherein:

Figure 1 is a central vertical longitudinal sectional viewof a theater'constructed in accordance with my invention. Fig. 2 is a plan View of parts of the structure shown in Fig. 1 with the roof supporting members omitted and with the floor of the balcony removed and part of the balcony broken away to show the mezzanine floor and stairway beneath the same.

Referring to the drawings, in which like numbers of reference designate like parts throughout, 1 is the main or orchestra floor on which the rows :of seats like that indicated at 2 are usually placed.

3 is the proscenium arch which spans the stage, and 4, the ordinary boxes at either side of the stage. Between the rear of "the orchestra and the front wall .5, extends a passage-way or corridor 6.

My improved structure comprises two cantaliver structures arranged upon different levels or planes oneabove the other, the

upper cantaliver structure 7, providing the balcony 8, on which is placed the stepped floor 9, for the rows of seats like that indicated at 10, and back of which is the balcony passage-way or corridor 11. The 'lower cantaliver structure 12, provides a mezzanine floo-r 13, which is located between the outer ends of the two cantaliver structures and each end of the mezzanine floor is in communication with the passage-way or corridor 6, by means of stairs 14.

By the term canta'liver structure I mean any suitable arrangement of beam or mea ,v

berson the cantaliver order, and each cantaliver structure :may 'be made of single beams or built up beams. In the present construction I show the cantaliver structures as made of composite iron work. The sup: porting columnsof the cantalivers may likewise be a single beam or may be a built up structure slike that used in ordinary iron wor'k. In-orderto give the necessary width' or lateral dimension to the balcony and to the mezzanine floor, a series of cantalivers are employed ineach of these parts, each senies having itsown supporting column, and the invention of course includes one such structure or .a series of the same.

In the construction shown the lower cantaliver structure comprises pairs of horizontally arranged

parallel beams

15 and 16,

an ordinary I-beam and union between the same and the respective horizontal beams 15 and T16, is made by means of ordinary angleplates 19 and 20, which are placed between the flanges of a column 17, and the webs of the respective beams 15 "and 16, and are riveted-to each-of these plates in the usual way. The outer end "of each of the horizontal beams 15 and 16., are united with a Vertical beam 21, which is of the -'I-beam type, and which as built into the front wall 5, of the building. This beam 21, and the wall-constitutetheanchorage of the outerend of the lower cantaliver structure and the respective beams 15 and '16 are fastened "to the I-beam 21, [by vmeans of a U-shaped plate 22, the back of which is placed against the flanges 'ofaone oftheI-bea'ms 21, and riveted thereto, and with its free ends riveted to the webs 'of the

respective beams

15 and 16. .At suitable intervals between the

beams

15 and 16, are arranged vertical webs 23, which are channel or U-shaped with the flanges thereof riveted to the webs of the respective beams between which they are interposed.

The columns 17, are arranged on a line between the back of the orchestra and the passageway or corridor 6, and they are placed on an arc corresponding with the curvature of the passage-way and the wall 5. The pair of

horizontal beams

15 and 16, are braced laterally by means of beams or members 24, the ends of which are secured or riveted to the horizontal beams in any well known manner, and these cross-beams extend parallel with each other, the crossbeams 24, at each side of the structure having their outer ends built into the side Wall 5*, of the building. The cross-beams 24, oocupy the space lying substantially between the row of columns 17, and the outer wall 5, and the remainder of the space between the

horizontal beams

15 and 16, are braced by diagonal braces and 26, the ends of which are united to the said horizontal beams of the cantaliver. The outer or free ends of the horizontal members of the cantaliver are secured together by means of a beam 27.

The upper cantaliver structure which provides the balcony and its corridor, comprises one or more beams or members 28, the main part of which is inclined downwardly in a manner suitable for the contour of the floor of the balcony, while the inner and free end is made horizontal for a short distance, and the outer end is also made horizontal as indicated at 29, and for a suliicient distance to provide the necessary width for the balcony corridor. The outer ends of each of the in- I clined beams 28, of the upper cantaliver are united with the vertical beam 21, by means of ordinary angle-plates 30, so as to anchor the outer ends of these members. The columns 17, extend upwardly above the lower cantaliver structure, and the upper ends are sccured'to the under side of the respective inclined beams 28 by means of suitable brackets 31. The inclined beam 28, is shown as being a built up structure, though it may be a single member and it is interposed between the outer ends of the subj acent

horizontal beams

15 and 16, respectively, and these parts are united by means of a short I-beam member 32, which is passed horizontally through the webs of the inclined beam 28, and has its respective ends securely united with the webs of the

beams

15 and 16, by means of suitable angle-plates and

rivets

33 and 34, respectively. The inclined beam 28, of the upper cantaliver are laterally braced by means of horizontally arranged cross-beams 35, which are arranged in parallelism and have their respective ends securely united with the sides of the respective inclined beams 28.

The two cantaliver structures thus described are arranged on difierent levels or on different planes, and between their outer ends where they are anchored and the verticalcolumns 17 which support them, ample space is provided for the mezzanine floor 13, the floor of which may be placed directly across the

horizontal beams

15 and 16, in any. suitable manner, and each end of the mezzanine is provided with a stair-way 14, which leads directly to the passage-way or corridor 6, on the level of the main floor. While the double cantaliver structure thus described, makes a special provision for the mezzanine floor, it will also be noted that it dispenses with the use of any supporting columns in the orchestra and gives a clear and unobstructed space throughout the part of the orchestra lying beneath the balcony. I also provide a special aisle or passage-way 36, which leads from the mezzanine floor to the stepped aisle 37, of the balcony, the floor 38, of the aisle being preferably inclined upwardly from the mezzanine to the stepped aisle 37. This gives ready access between the lower rows of seats in the balcony and the mezzanine which may be used for any special purpose desired in places of this kind.

The roof indicated at 39, is suitably supported by trusses 40, reaching from the proscenium arch or wall 3, to the supporting columns 41, the lower ends of which rest upon and are secured to the inclined beams 28, of the upper cantaliver structure.

I wish to be understood as not limiting my invention to the specific forms of the structures herein shown, as it is evident that various modifications may be made in the different parts of the structure without, however, departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a structure of the class described, the combination of a lower load-supporting member anchored at its outer end, a support for said lower member intermediate its ends, an upper load-supporting member anchored at its outer end and inclined downwardly toward said lower member and supported by said lower member on the side of said support away from which said member is anchored, and a balcony located upon said upper member, substantially as described.

2. In a structure of the class described, the combination of a lower load-supporting member anchored at its outer end, a support for said lower member intermediate its ends, an upper load-supporting member anchored at its outer end and inclined downwardly toward said lower member and supported by said lower member on the side of said support away from which said member is anchored, a support for said upper member intermediate its anchorage and its point of support on said lower member, and a balcony located upon said upper member, substantially as described.

3. In a structure of the class described, the combination of a lower load-supporting member anchored at its outer end, a support for said lower member intermediate its ends, an upper load-supporting member anchored at its outer end and inclined downwardly toward said lower member and supported by said lower member on the side of said support away from which said member is anchored, a mezzanine floor located between the outer ends of said upper and lower member, and a balcony located upon said upper member, substantially as described.

4. In a structure of the class described, the combination of a lower load-supporting member anchored at its outer end, a support for said member intermediate its ends, an upper load-supporting member anchored at its outer end and inclined downwardly toward said lower member and supported by said lower member on the side of said support away from which said member is anchored, a mezzanine floor located between the outer ends of said upper and lower member, a balcony located upon said upper member, and an aisle extending from the level of the mezzanine floor to the incline of said balcony, substantially as described.

5. In a structure of the class described, the combination of an upper and a lower loadsupporting member arranged one above the other and anchored at their outer ends, a column supporting both of said members intermediate their ends, the said upper member being inclined downwardly toward the lower one and being supported thereby on the side of the column away from which said members are anchored, and a balcony disposed upon and supported by said upper member, substantially as described.

6. In a structure of the class described, the combination of an upper and a lower loadsupporting member anchored at their outer ends and each having a support intermediate its ends, the said upper member extending horizontally for a short distance from its point" of anchorage and then inclined downwardly and to a point beyond the inner end of said lower member and supported by said lower member on the side of said support away from which said member is anchored and a balcony following the incline of said upper member, substantially as described.

In witness whereof, I have hereunto set my hand in the presence of the two subscribing witnesses.

FREDERICK MEISTER.
