J. F. KACENA ADJUSTABLE TRESTLE Filed March 18, 1932 Nov. 21, 1933.
In z/eizfof Lfose ii fffacegza Patented Nov. 21, 1933 ADJUSTABLE TRESTLE Joseph F. Kacena, Chicago, Ill.
Application March 18,
2 Claims.
An object of this invention is to provide an adjustable trestle which is durable, easily assembled and disassembled, and which is foldable when not in use to occupy a minimum space.
This and other objects, as will hereinafter appear, are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawing, in which Figure 1 is a perspective View of a trestle show ing the beam in its uppermost position of adjustment;
Fig. 2 is an enlarged vertical section of one end of the trestle taken as indicated by the line 2-2 of Fig. 1, the beam being shown in dotted lines in its various positions of adjustment;
Fig. 3 is an enlarged vertical sectional view taken on the line 33 of Fig. 2; and
Fig. 4 is a fragmentary sectional view taken on line 4 of Fig. 2. The embodiment illustrated comprises a trestle having a beam 10 adapted to be supported in a horizontal position by A-shaped frame members 11 secured to the beam near its ends. Each of the frame members are identical so that it will be necessary to describe but one.
The frame member comprises a pair of legs 12'.
and 13 which may be formed of angle or channel iron, each leg extending outwardly and downwardly, and preferably. terminating in feet It and 15. The legs are held spaced apart by cross bars 18 and 19 which may be riveted or welded to them near the middle. The upper ends of the legs are substantially parallel to form clamping jaws 16, 17 which are spaced apart a distance about equal to the thickness of the beam.
The clamping jaws are provided with spaced holes 20 to receive a bolt 21 extending through both of the jaws. A hand nut 22 is screwed on the bolt and adapted to clamp the jaws tightly against the beam. It will be noted by referring to Fig. 2 that the beam, when placed in lowermost position in the frame, rests upon the cross bar 18, and when placed in any of the elevated positions will rest upon the bolt 21.
To give the trestle stiffness and prevent it from collapsing in a direction lengthwise of the beam,
an angular beam 23 is pivotally mounted on a bracket 24 which is rigidly secured to the bar 19. The free end of the brace is provided with a hook is pivoted to the cross bar so that it may be clamp 25 having a point 26 for engaging the 1932. Serial No. 599,735
swung at any angle, as beam is placed at vario shown in Fig. 2, as
the
us heights.
To assemble the trestle, the bolts 21 are first adjusted for height, and
the beam is then gripped in the desired position between the jaws of one frame which stands substantially at right angles thereto. The brace 23 upper end overlies the hook clamp is turned. to
and tightened by means of the hand nut. other frame member is then applied in the same way.
is then turned until its beam, after which the engage the opposite'side The a trestle frame which is weight to handle, and small space when not in of a convenient size and which can be stored in use.
While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications.
Changes, therefore, in the construction and arrangement'may be made Which do not depart from the spirit and scope of the invention as disclosed in the appended claims.
I claim:
means on its beam. 7
2. In adjustable trest two spaced leg members, idly connected to said 'members 'having'upw'a .outer end for clamping it to the les, a frame comprising transverse members rigleg members, said leg rdly extending parallel portions adapted to receive a beam between them, said parallel portions having pairs of registering openings therein, and a clamping bolt adapted to extend through any pair of said registering openings for clamping said parallel portions to thebeam at different he ights. JOSEPH F. KACENA.
