' TRES TLE. I
Specification of Letters Patent.
Application filed April 17, 1906. Serial No. 312,093.
Patented Jan. 22,1907.
To all. whom, it may concern:
Be it known that I, DENISON P. CHEsEBRo, a citizen of the United States, and a resident of New York, in State of New York, (with post-office address Sixty-fourth street, corner of First avenue,) certain new and useful Imhave invented provements in Trestles, of which. the following is a specification.
This invention relates to trestles for builders or other miscellaneous use, the object being to construct a trestle of a fewer number of parts than those at present in use and at the same time retain the necessary rigidity and strength.
A further object is to construct a trestle whlch is capable of being readily taken apart and which When so for convenience in shipping, storage, &c., knocked down will re quire a minimum amount of space.
The device consists of a main frame provided with the usual cross-beam for supporting planks or for any other desired use. To one end of this frame is attached a pair of inbeing perpendicular to frame and preferably removable therefrom.
The upper part of the legs form a seat for the cross-beam of the main frame, the lower part being held to the frame by means of a cleat or any other suitable means, thereby keeping the main frame in a vertical position. I,
however, do not limit myself to this manner of assembling the trestle, as the same might be varied in many ways without departing from my invention, which consists, broadly,
in a knockdown trestle composed of but two parts and having but one bracing member for the main frame or cross-beam.
In the accompanying drawings, Figure 1 is a perspective view of my invention. Fig. I 2 is a side elevation of a part of the same and shows the manner in which the crossbeam is supported at its'one end.
The cross-beam A is suitably supported by the standards B and C, secured thereto and properly braced.
D represents a pair of legs formed into an nverted V and are removably attached to me end of the beam B in the following man- 1 the plane of the main the county of New York and 1 verted-V-shaped legs, the plane of the legs ner: As shown in Fig 2, the upper part of the legs D are formed to receive the beam A, so that they, with the brace E, form a seat for the said beam A. The standard C is provided with a cleat G, adapted to receive the lower brace F of the legs D. The parts are assembled in an obvious manner by first inserting the brace F in the cleat G, thelegs D swinging up and receiving the beam A.
A pin K passes through a hole in the beam A and prevents the legs D being displaced while in use.
As'will be obvious, the standards B and C support the main weight which the trestle might be supporting, the legs D being pro vided as a brace and to keep the trestle in a vertical position. When taken apart, the parts of the trestle being fiat can very easily be transported from place to place, and a great number of them can be stored in much less space than would be taken up by the trestles as at present constructed.
It is preferable to construct the cross-bar A with two standards in order to have that part of the device thoroughly braced when the trestle is knocked down, but it is obvious that the standard C might be dispensed with, the legs D taking its place and also maintaining the trestle vertical.
What I claim as my invention is 1. A knockdown trestle consisting of a main frame comprising a horizontal beam and permanently attached and braced perpendicular supporting-posts for the same, and a removable transverse leg-frame located at one end of said beam.
2. In a trestle, the combination of a main frame comprising a horizontal beam, and permanently attached and braced perpendic- ,ular supporting-posts at each end of said beam, a transverse leg-frame at one end of said beam and a socket in said transverse legframe in which one end of said beam rests.
Signed at New York, in the county of New York and State of New York, this 12th day of April, A. D. 1906.
