2 Claims.
Thepresent invention relates to new and useful improvements in horses or trestles of a type commonly used by carpenters or other persons employed in building construction and has for its object to providemeans for collapsing the legs of the I trestle into a compact form when the trestle ls not in use. I
v 'A. further object 01' the invention is to provide a deviceoi thischaracter of simple and practical construction which is strong and durable, relatively; inexpensive tomanuiacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details oiconstruction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to lik parts throughout, and in' which- Figure 1' is a side elevational view,
Figure 2is an end elevational view,
Figure 3 is a fragmentary bottom plan view,
Figure 4 is a perspective view of one of the plates secured to the leg of the trestle provided with the locking tongue,
Figure 5 is a similar view of the plate attached to the under side of the beam of the trestle and to which the legs are pivotally attached,
7 Figure 6 is a fragmentary sectional view through the locking tongue with the plate engaged thereby,
Figure 7 is a perspective view of one of the pivted brace members, and Figure 8 is a perspective view of one of the lower brace members for the leg.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the board or beam of the horse supported at each end upon a pair of legs 6.
wood or any other suitable material and the manner of connecting the legs at each end of the cent its end, is an inverted U-shaped plate member 1 secured in position by screws 8 or the like,
the plate including downwardly extending wingportions '1' provided with an opening 9 through which a rivet or the like I0 is inserted for piv-.-
ot-ally attaching the respective legs tosaid wings in a manner more fully hereinafter explained.
The beam and the legs may be constructed of I shown to advantage in Figures 2. and'3 oi the drawings.
The vertical edge of each of the wings I, adjacent the outer ends of the'beamlisuprovided with a flange ll against which the legs' 8 areadapted to abut when the legs are in their open position. 'Adjacent the lower ends 01' the flanges H is an opening I2 adapted to receive a pin l3 for pivotally attaching a sectional latch l4. The latch I4 is composed oia pair of duplicate sections shown in detail in Fi ure?! ,ofthe drawings, each of the sections comprising a plate member I! at one comer of which is the opening I for pivotally mounting on the pin-i3 and ad- Jacent the end edge provided with the opening I6 is a slotted opening I! adaptedior locking engagement 'w'ith'a pin l8 projecting outwardly from the leg 6. The sections of the latch l4 extend inwardly toward each other-from the opposite legs as shown to advantage in Figure 2 of the drawings, and the adjacentends of the latch sections are disposed in overlapping relation and are pivotally connected bymeans of a pin ll working in'a slotted opening 29 formed in the f overlapping end of the section: l5 otthe'latch". Secured to the inside of eachof the legs is a U-shaped plate 2| having flanges 22 at each edge thereof disposed in abuttingrelation against the opposite edges of the legs and s'ecured thereto by screws or the like 23. -An' upstanding tongue 24 is struck from the central portion of the plate. 2!, the tongue being adapted to receive one of the wings I in frictional engagement therewith when the legs are disposed in their upright or open ,position. One of the flanges 22 of the platev is of reduced length and the ad- Jacent upper corner of the plate is inclined as shown at 26 to. permit the pivotal folding movement of the legs inwardly against the under side v of the beam 6 in the direction. as shown by the arrow in Figure 1 of the drawings.
The inner ends of the wings'l are curved as .On one of the flanges 22 is formed a boss 28 s preferably by pressing the material of the flange outwardly and in. which an opening 29 is provided for receiving the pin l-8,'the boss serving The legs are positioned outwardly'of the wings as 55 to space the latch i4 outwardly from the flange 22. The pin I8 is also provided with a head ill tofrictionally bind the pin in the slot 11.
The lower portion of each pair of legs are also connected with a brace 3| of angle-iron, the brace being pivoted at one end as at 32 to one leg and is provided at its other end with a keyhole slot 33 adapted to receive a headed pin 34 on the other leg. One flange of the brace is shortened as shown in Figure 8 so that the ends of the shortened flange will abut and brace the inner sides of the legs as shown in Figure 3.
It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.
' Having thus described the invention, what 1 claim is- 1. A trestle of the class described comprising a beam, a plate secured to the under side of the beam adjacent each end thereof, downwardly extending wings on the plate, a leg pivoted to each wing for swinging into and out of position under the beam, a plate carried by each leg, a tongue on said last named plate slidably engaging an and pins carried by the legs and engageable by the respective sections of the latch to secure the legs against swinging movement in an upright position. I
2 A trestle of the class described comprising a beam, a plate secured to the under side of the beam adjacent each end thereof, downwardly extending wings on the plate, a leg pivoted'to each wing for swinging into and out or position under the beam, a plate carried by each leg, a tongue on said last named plate slidably engaging an adjacent wing to maintain the wing in close engagement with the leg and a sectional latch including a pair'oi' plates pivoted at one end to each other, the other ends of the latch plates being pivoted to the respective wings, said latch plates having notches therein and pins carried by the legs engaged in the notches for securing the legs against folding movement.
