JOHN MLN'ES, JR., OF PORT RICHMOND, NEW YORK.

BUTLDERS HORSE R TRESTLE.

Application filed April 9, 1919.

To all whom it may concern.'

Be it known that I, JOHN MILNEs, Jr., a citizen of the United States, residing at Port Richmond, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Builders Horses or Trestles, of which the following is a specification.

This invention relates to horses or trestles of the Lype commonly used by carpenters, contractors or other persons engaged in building constructions, and an object of the invention is to provide a horse or trcstle of this nature which may be easily collapsed or folded to form a compact structure thereby 'facilitating the transportation, and also facilitating its storage, in that the collapsed trestle or horse will occupy a much smaller space than occupied by the ordinary type of wooden horse or trestle commonly used by carpenters or contractors. i

Another object of the invention is to provide a trestle or horse as specified, in which the supporting parts are formed of metaln and which supporting parts are' in turn pivotally connected to saddle members so that they may be folded to lie in substantially parallel relation with each other and with a wooden seat carried by the saddle members, allowing the horse or trestle to he folded into a relatively compact sruf'ture.

A still further object of the invention is to provide a builders horse. or trestle as specified, wherein all of the parts are constructed of metal with the exception of the beams thereof, the said beams constructed of wood to permit the nailing thereto of scaffolding or platform boards or to permit the nailing of the beams of one trestle to the bottom of a second trestle when using the trestles in superposed relation for providing .the scaffolding. Y

Other objects of the invention will appear in the follovvin detailed description taken in connection with the accompanying drawings, forming a part of this specification7 and in which drawings:

Figure 1 is a side elevation of the improved trestle. i

Fig. 2 is an end elevation of the'trestle.

Fig. 3 is a side elevation of the trestle or horse showing the same in Afflded position.

Fig. 4 is a section on the line 4.--4 of Fig. 1.

Serial No. 288,717,

Fig. 5 -is a section on Athe line 5--5 of eferring more particularly to the drawings, 1 and 2 indicate the supporting leg structures of the builders horse or trestle structure, each of which comprise a pair of angle hars 3 and 4 converging toward their upper ends, and connected at their upper ends by the transversely extending angle irons 5. The converging supporting legs 3 and 4 are also braced and connected intermediate their ends by transverse angle irons 6. The legs?, and 4 of each of the` supporting leg structures 1 and 2 have horizontal feet or extensions 7 formed thereon and extending outwardly therefrom, through which openin s 8 extend, the said openings being provi ed to receive therethrough screws, nails or analogous fastening devices to fix the trestle or horse in any predetermined desired position.

The supporting leg structure 1 -is pivotally connected by means of a pin 9 to a substantially U-shaped saddle structure 1() while the supporting leg structure 2 is connected by means of links 11, to which the legs 3 and 4 thereof are pivotally connected, to a saddle structure 12, which is also substantially U- shaped in cross section and alines with the saddle structure 10. These substantially U- shaped saddle structures 10 and 12 support the beam 13 of the horse or trestle structure which is constructed of wood so as to permit scaffolding boards, platform boards or work to be nailed or otherwise suitably attached thereto, and also to permit of the nailing or fastening of an extension 7 of one trestle to the beams 13 of other trestles when the trestles are employed for .forming supports for seaifolding. As clearly shown inl Fig. 3 of the drawings, the link structures 11 permit the folding of the leg structures 2 into substantially parallel relation to the leg structure 14 and beams 123, When the said leg structures l and 2 are folded to renderthe trestle or horse structure compact for shipment or storage.`

The intermediate bracing angle irons 6 of each of the supporting leg structures 1 and 2 have bracing bars 14 pivotally connected thereto through the medium of angled plates 15 and these oars 14 have their ,inner ends provided with a plurality of spaced openings 16 adapted to receive bolts 17 therethrough for connecting 'the ends of the said 'operative position.

bra'ee,` members to securely brace the supportmg leg structures 1 and 2 m a folded and The outward pivotal movement of the supporting leg sections l and 2 is limited by the engagement of the angled bra'ees 5 against the under surfaces ot' the saddle members l() and l2 as clearly shown in Fig. l ot the drawings, the said saddle members forming firm supporting connections between sup-v porting legs l and 2 when the latter are in an operative supporting position, relieving the pivot pins ot' the legs of much of the strain of supportingvthe work or material placedupon the beams 13.

A chain or analogous fiexible member 1S is attached to the beam 13 and the same beam also carries a hook 19. The chain or analogous flexible member 1S is provided for engaging about the supporting leg structures l and 2 when the structure is collapsed, to connect them to the said beam and hold them against accidental untolding movement.

Changes in details may be made without l departing from the spirit of this invention,

but;

I claim: l. In a builders horse or trestle, the comfbination ol"v4 substantially U-shaped saddle members, supporting legs pivotally connected to sald saddle members, a Wood beam vdisposed Within said saddle members, and

angle irons carried by said supporting legs and adapted for engagement against the under surfaces ot' said saddle members to limit the outward pivotal movement of the legs with respect to the saddle members.

2. In a builders horse or trestle, the combination of substantially U-shaped saddle .meinbers, supporting legs pivotally eon neeted to said saddle members, a Wood beam disposed within said saddle members, angle irons carried by said supporting legs and adapted for engagement against the under surfaces ot said saddle members to limit the outward pivotal movement ot' the legs with respect to the saddle members, brace rods pivotally connected to the supporting legs,

and means for connecting the meeting endsbination of substantially U-shaped saddle members, supporting leg struetures,- each comprising a pair ot' upwardly converging legs, angle braces'connecting the upper ends ot' said legs, one of said supporting leg structures being pivoted Vdirectly to one of Said saddles, links pivotally eonneeted to the other leg structure and the other of the saddle members, whereby said leg structures may be folded in substantially parallel renecting said saddle members, said angled braces adapted for engagement against the under surfaees of said U-sliaped saddles to limit out\ Yard pivotal movement of the supporting leg structures.
