.It .is .another object of my inventionto provide such an adjustablescaffoldhorse, which is'comparatively light in weight and may be easily and quickly moved from place to place. Y 1 v Y One. of the importantfeatures of my present improvements resides in the pro-vision of end supports for a horizontal member of vcylindrical form, .each ofy which cjonsists of two-: diverging legs, havingl interlocking parts attheir upper ends, each provided with means for'engagement upon oneside of said cylindrical member and adapted to be adjusted circumferentially thereon, together with means-:for separably .clamping said Ainterlocked members. ,to said cylindrical .member and therebyunaintain the diverging legs in their adjusted positions. -In addition to the means. .just referred to for ,adjustingand positioningthe. diverging supporting! legs. circumferentially of the horizontal cylindrical' member, I also lpreferably provide an adjustablel longitudinal extension for each of said supporting legs, whereby said horizontal member mayl be vertically adjusted and `positioned at any desiredheight above the ground or floor surface.v
It is a: further general object of the invention to provide a scaffold horse'whereinthe several parts maybeeasily and quickly assembled or disassembled, and which, when not'in use, is capableof very. compact arrangement, `so that the device will occupy but little storage space. i.
Vith thevv above and' other-objects in view, the invention consists in the improved scaffold lhorse and in the form, construction and relative arrangement of its several parts,
as will behereinafter more fully described, illustrated 'in the accompanying drawings and subsequently ,incorporated in the subjoinedclaims. i In; the drawings. wherein I have illustrated one simple :and lpractical embodiment oftheinvention and in which similar reference characters designate corresponding parts throughout theseveral views,
Figure -.1. is a side elevation, illustrating a preferred embodiment of my present improvements, i' f vFigure 2 is an end view, Figure 3 is an enlarged detail vertical section taken on the line-3 3 of Figure l,
Figure 4 is asimilar vertical section taken on the line`4-4 of Figure l,
Figure 5 is a-horizontal ysectional view takenion-tlieilineie of Figure 4l,
`Fig'gfures 6; and .7 .arefdetailA elevations of thetwointerlocking clamping members for the horizontal platform supporting rod, and ,FigureB is a detail longitudinal section taken-.on the vline 8 8 of Figure 1.
yInf-the accompanying drawing, for purposes of illustration, I have shown aI practical embodiment of my present improvements, -which Iy have foundvery convenient .and serviceable-:fin vrpractical use, and in which the,horizontalmember ofthe horse uponnwhich thescatfold planksY orbo'ards are laid, is.' inthe .form of a cylindrical rod 5. Preferably,- for the sake of lightness, this rod cofnsists ofa' tube or pipe Iof any desired length, as required in accordance 'with the Width of the scaffold platform to be arrangedfthereon. l i
..The cylindrical rod ,5 is adaptedv to -be Vni'c'uintedor arranged at' its opposite ends in suitable supports. As herein shown, each of the-supports consists of apair of legsG, also preferably oftubular cylindrical form, and of any desired length. One end of each of the supporting legs is Xed in a sleeve 8, formed-upon one'side ofa metal plate 7. If. desired, theglegs 6- may be removably secured'inthe respective sleevesS by a suitable locking key-.or pin extending through coinciding openings inthe sleeve and leg, or', the leg may be permanently fixed in said sleeve.l 'Each vof the plates Tais-provided at one l.of its ends Vwith `atransversely; curved flange 9, whichv is adapted for engagement upon one; sidegl' of the' vtubular memberV 5 as willbefmorefully hereinafter explained. In spaced relat'ionfto thegiianges 9, each-of the plates 7 is provided" upony the inner face- Clt Cil
thereof with a rib, as sho-wn at and 11 respectively. The rib 10 is provided with a lug 12 `for interlocking engagement in a complementary recess 13 formed in the rib 11. Between the ribs 10 and 11 and the Afianges 9, each plate 7 is provided with an opening therein to receive the connecting bolt 14, lsaid plates being provided at their outer sides with the bosses 15, through which said bolt extends. Upon one end of the boltl, a winged nut 16 is threaded to coact with one of the bosses and draw the head 17 on the other end of said bolt into tight engagement with the other boss 15. In this manner, the interloclred plates 7 are detachably connected and the fianges 9 thereof are idrawn into tight clamping engagement against the opposite sides of the tubular member 5.
ln Lthe lower end of each leg 6, an extension member 18 is slidably fitted, said member preferably having a flange 19 at one end for contact with the floor surface, and being provided with longitudinally spaced openings 2O to register with openings in the wall of the legs 6 and receive a locking pin 21. The member 1S is also preferably of tubular form, and it will be understood that by providing this extensible and adjustable member for each of the legs 6, the length of the supporting legs may be increased or decreased within certain limits to position the platform supporting bar 5 at a desired height above the ground surface.
if desired, for purposes of greater security, the diverging legs 6 may be connected intermediate of their ends, by transverse brace bars 22. However, in many cases, and particularly where the scaffold platform will not be required to sustain very heavy loads,
lthese transverse braces may be dispensed with, so that when the device is not in use, the two legs 6 can be entirely separated from each other.
In the use of the device, as above described, it will be understood that the portions of the plates 7 provided with the curved flanges 9 are relatively yieldable in vthe adjustment of the clamping nut 16. Thus, norn'ially, the space between the inner surfaces of these flanges is slightly greater than the diameter of the tubular member 5 so thatv said member may be readily fitted between said curved flanges. After the member 5 has thus been arranged at its opposite ends between the flanges 9 of the spaced supports, the clamping nuts 16 are v:uljusted so as to draw said anges 9 inwardly towards each other and thus tightly clamp the same upon the member 5. It will be noted that the upper edges of these flanges are substantially in tangential relation with the periphery of the. cylindrical member 5, so that the boards of the scaffold platform may be laid upon the upper side of the member 5 throughout the length thereof. By looseningl the nut 16 slightly, the fianges 9 may be moved circumferentially upon the tubular member 5. By reason of such circumferential adjustment'of N the supports, at their upper ends upon the scaffold receiving rod or member 5, the lower ends of the supporting legs may be positioned respectively with relation to the ground surface and upon an obstruction, which otherwise could not be avoided, and thus secure a firm and rigid support for the rod 5, which will prevent any tilting of said rod from its proper position to support the scaffold platform in a horizontal plane. ln other instances, in addition to this Circumfereutial adjustment of the supports relative to the rod 5, it may be necessary to also use the adjustable extension members 18, whereby one leg can be lengthened relative to the other. It of course will also be apparent that the supports can be readily adjusted longitudinally along the rod 5 and spaced at any desired distance from each other. With a series of such scaffold horses arranged in spaced relation, a scaffold platform of any desiree. length can be readily erected. A scaffold horse of this construction, as will be apparent from the foregoing description, provides a very firm and rigid support for the platform so that it will not collapse under heayy loads. At the same time, it will be noted that the device is of such construction that it will be comparatively light in weight and can be easily and quickly transported from place to place. This may be done by merely resting the tubular rod 5 at its approximate center upon the shoulder and owing to the fact that the surface of this rod is cylindrical, it will not cut into the shoulder, or cause appreciable discomfort.
From the foregoing description, considered in connection with the accompanying drawings, the construction and manner of use of my improved scaffold horse will be clearly understood. lt will be seen that the device, owing to its simple construction may be produced at relatively small cost and by interlocking the supporting legs in each pair with each other, and rigidly clamping the same at their upperends upon the platform receiving rod, a very rigid supporting structure is produced. Vhen the device is not in use, the clamping nuts 16 can be readily loosened and the cylindrical rod 5 removed. The two supports with this rod can then be very compactly arranged and stored away in a relatively small space.
l have herein illustrated an embodiment of my present improvement, which is very efficient and serviceable in use, but nevertheless it will be understood that the purposes thereof might possibly be attained by other alternative constructions and I therefore reserve the privilege of adopting all .such legitimate changes in the form, construction and relative arrangement of the several parts as may be fairly embodied Within the spirit and scope of thelinvention as claimed.
I claim l. A scaffold horse comprising a cylindrical scaffold sustaining member, a pair of supporting plates for said member, each plate provided at its upper end With a curved fiange adapted to bear against the side of the sustaining member, interlocking means on the lower ends of said plates whereby they interlockingly engage and are disposed in a divergent relation, said plates being apertured between the interlocking means and the flanges and a clamping bolt adapted to extend through said apertures to hold the plates in propel' relation to each other and with the flanges against the sustaining member.
2. A scaffold horse which includes a supporting plate, the upper end of which is provided with a circumferentially curved flange, the lower portion of which, on its inner face is provided With an interlocking rib adapted to interlock with a similar plate, and an apertured boss on the plate intermediate the flange and the rib to receive a clamping bolt.
3. A scaffold horse which includes a pair of supporting plates having their upper ends provided with circumferentially curved flanges and their lower ends provided on the inner faces thereof with interlocking ribs, apertured bosses on the plates between the flanges and the ribs to receive a removable clamping bolt, said bolt adapted when adjusted, to cause the interlocking action of the ribs, and to hold the flanges against the opposite sides of the scaffold sustaining member.
In testimony that l claim the foregoing as my invention, and have signed my name hereto.
