Patented Mar. 13, 1928.
UNITED STATES 1,662,7tiii FRANK P. DYER, OF ST. LOUIS, IEISSOURI.
TRESTLE.
Application filed February 7, 1927. Serial No.1G6,5' 61.
This invention relates to trestlcs and its primary object is to provide a trestle of the foldable and knock-down type, for use by mechanics such as carpenters, paper hange. and the like, that can be expeditiously set up to provide a strong, sturdy and substantial supporting structure Olt' any size and height within the limits of the structure, and can be easily and quickly reduced when not in use to occupy minimum space in storage and to render the same easily transport able in great numbers.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.
In describing my invention in detail, retercnce will be had to the accompany drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a perspective view of the trestle forming the subject matter ot the present invention and showing the same assembled.
Figure 2 is a fragmentary side elevation and illustrating the supporting legs and brace means therefor.
Figure 3 is a sectional view taken on line of Figure 2.
Figure 4L is a detail view showing an extension for one of the legs.
Referring to the drawings in detail t] e standards or legs are arranged in cooperating pairs and each pair includes uprights l. and 2 pivotally secured "for cooperation adjacent the upper ends by spacedparallel strips 3. Cross braces 4- are also provided for the uprights and these braces are longitudinally slotted as at 5 to receive bolts 6 having thumb nuts 7 associated therewith as best shown in Figure 1 of the drawings.
The upper ends of the uprights 1 and 2 are recessed. as at 8 for providing shoulders 9 and to accommodate the cross beam 10 which may be of various sizes and lengths and yet be adequately and substantially supported by the standards as will be readily a parent. Converging brace rods are provided for the cross beam 10 and include angle bent lower ends 11 having openings adapted to receive the bolts 6 as clearly shown in Figure 2 of the drawings. The converging rods have bent tapered upper ends providing penetrating points adapted to be embedded in the beams in the manner as best shown in Figure 2', and thereby adequately support the central portion of the beam as will be readily apparent.
I have also provided sleeves 18 adapted to telescopically receive the uprights 1 and 2 and these sleeves have arranged therein thumb bolts 1 1 whereby they can be adjusted on the uprights 1 and 2 to also change the height of the trestle as desired.
From the above description and disclosure of the drawings, it will be obvious that l have provided a trestle formed with legs which include uprights mounted for ad'j 11st ment with respect to each other so that the space between the recessed ends can be varied to accommodate beams 10 of various widths and which also will enable the trestle to be adjusted to various heights by the movement of the legs toward and away from each other.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily appz'u'ent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes tall within the scope of the appended claim.
lVhat I claim is:
A trestle of the character described comprising a pair of upwardly converging legs spaced at their upper ends, a pair of? spaced oppositely disposed cross members pivotally connected to said legs adjacent their upper ends, a cross beam received between said upper ends and supported by said cross members, a longitudinally slotted cross member and bolts and wing nuts for adjustably connecting said slotted cross member to said legs at intermediz-ite points of said legs, said bolts being slidably extended through said slot brace members pivotally connected to said legs by said bolts and converging upwardly toward the center of said cross beam, said brace members having penetrating points formed thereon and arranged at angles thereto and embedded in said cross beam substantially as described.
In testimony whereof I affix mysi nature.
' FRANK P. DYER.
