AUTOMATIC ALLY-ADJUSTABLE BASE.: Application, filed February 20, 1923. Serial No'.. 680,145.
This invention is. especially adapted for
use" as a base for supporting paint buckets,
and the like, to keep: the same level oh in
clined surfaces such :as. roofs and the like
5 and on convex and concave surf aces such for
instance as on the outside or inside round-.
ing surface of a large pipe, drum or :globe.
An object of this invention \is to^ facili
tate the use of paint buckets and,,other open
10 top containers on roofs and other non-level surfaces; and the invention is broadly new, basic and pioneer in that I provide a vessel holder with a loosely jointed toggle like support adapted to swing below the holder when"
10 the same is supported by hand independently of any other support, and adapted to conform by its own weight to such surface as it may be lowered onto, and to retain the position at which the vessel holder is brought
20 to rest, irrespective as to whether it be -the side or the peak of a roof or in a valley or gutter; and which will retain the holder in the position it is in when the parts come 'to rest, and hold such pail or other receptacle,
25 against accidental displacement, or tilting on the base, and which is constructed to pre-; vent any slipping of said base on the surface. on which it may be- placed., Another object is to provide for inclined"
so surfaces, a base for pails and the like which may quickly and easily be .moved frOm place to place as the work progresses, thus to avoid the necessity of fixing a bracket, a framework, or cleats to or on the roof at
35 each placing of said pail.
Another object is to provide for pails and other receptacles, a base: to which the .receptacle may quickly and easily be attached and as quickly and easily detached when de
40 sired. • .. , . '- .'.'..'
An object is to make provision whereby the pail and base may be lifted by the bail of the pail and carried from place to place without disengaging the pail from the base.
An advantage is that the -base is anti
slipping so that its use enables the workmen. to leave the surface from which it has been removed, free from nail holes.
The invention is adapted to be used by
50 other mechanics and builders ;.. being suitable
for use by shinglers to hold their shingles, or
to sit on; or by tinners to 'support their fire
pots; and by brick layers to hold brick or
mortar etc., and the device may be made of different sizes and .materials to suit the oc- 55 casion. . ' • '•'[••'' •' • ;:' ';:'" , '•; .'
The invention includes, a seat supporting jointed frame comprising two swinging stay legs pivoted oh" axes that are in fixed rela-; tipn to the seat, and two tie legs that :are pivot ally connected* together by a lost iiiotion connection, and respectively ^pivoted, to the stay legs, the ties being adapted to, linear adjustment to hold the stays rigidly aslant at reversed angles relative to the seat and to each other and also adapted to angular adjustment to hold the stays rigidly extended toward the opposite ends of one or the other of the tie's. , , •
Other objects, advantages and features of invention may appear from the accompany-. ing drawing, the subjoined detail description and the appended claims.
The accompanying drawing illustrates the invention. ;.. ', .

The platform or rigid seat; T is adapted to hold a pail or receptacle 2 and is ;pivoted to a jointed -frame that is adjustable to '.various surfaces, such as, horizontal, concave, convex or slanting, while the seat 1 is horizontal, and that will support the seat and its, load when the .frame is thus adjusted. . . '" •,.. /•'. . '' '..." .•;' :,"' :;,.-/ /'
The frame is composed of a pair of toggles 3 pivoted to ears 4', 5' that are arranged in pairs spaced apart at opposite edges of the platform 1 and that extend down from
c said platform.
Each toggle is composed of four limbs comprising a pair of braces 4, 5 and a pair of ties 6, 7. The braces are pivoted at one end to said ears; the braces 4, 4 being pivo't
10 ed to the ears 4', 4' and the braces 5, 5 being pivoted to the ears 5', 5'.' The limbs 6, 7, of the ties are each approximately equal .in length to the space between centers of their pivots 8, 9 that connect them with the ears
15 4', 5' that are secured to the platform. 1 or seat by the rigid strips 10 and 11 so that the seat is rigid and the pivotal axes at 4' and 5'are held in parallelism.
The long limbs'6, 7 are connected together
20 by a lost motion pivotal connection at 12, and are also pivoted at 13, 14 to the short limbs 4, 5 and to the rigid base bars 15, 16 which are turned up at the ends to form ears arid which base bars and their pivotal
25 axes 13,! 14 and. .the pivotal axis 12 are held in parallelism- with each, other.
"Stops 17, 18 are provided on the limbs 4, 5 to bear against the limbs 6, 7 for the purpose of. insuring the toggles against col
30 lapse. Spurs 19 are provided on the underside of the seat to engage the roof in case the base is placed on the inclined surface of such" roof. Said spurs' are preferably formed of the down-turned ends of a strip
35 or bar 20 of metal applied directly beneath the. strip 11; said . ends being pointed to form the spurs 19.
Rivets 21 are used to attach both the strips 11 and 20 to the seat 1. Said spurs 19 are
40 of a length to merely catch, into the roof sufficiently to retain 'the base on the slanting 'surface of the roof .as shown in Fig. 5 when' such roof is composed of shingles or any penetrable material riot likely to be in
45 jui'ed by the spurs. In this position the stops 17 will engage against the stay legs 6 to rigidly support the outer end of the platform 1. Provision is made to prevent slipping in
so cases where the use of spurs might prove injurious 'as on roofing or the .Tike, such provision being a strip 22 of rubber attached to the underside, of the seat 1 at the edge opposite to that near which the spurs 19
5-> are 'placed; said strip 22 .extending flush with or a trifle beyond the edge 23 of the platform. Fig. 8 shows in dot arid, dash lines the position of the base in such engagement. 'Thus the base may be turned at,
co pleasure to engage at either'edge with tl}e roof, as " occasion requires. It is seen that in a balanced, position as shown in Figs. - 3 or 6, the 'retainers 19 and. 22. are hot'.required and are out of the way. «
"5 Means for clamping a pail or receptacle 2
on the platform 1 are shown in Figs. 1 to 7 inclusive. The clamping means may be in the form of curved jaws 24 adapted for use with a circular pail or with straight and parallel jaws 24' as shown in Fig. 7 to be u's'ed~wifli a rectangular receptacle.
Said jaws or clamps 24,24' are operated as shown in Fig. 2 by means of slides 25, links 26, lever 27, spring 28 and pull rod 29. The slides 25 are attached at one end to the clamps 24 and operate in slideways 30 while the other ends of the slides 25 are pivotally connected by the links 2G to the' lever 27; said lever being pivoted at 31 to the platform 1 arid operated by pull rod 29 against the tension of the spring 28 which connects the outer end of the lever 27 with the platform 1.
The clamping means may be omitted if desired as shown in Fig. 8.
The parts of the frame' arc arranged in pairs, as the stay legs 4, 4 and 5, 5; the tic limbs 6, 6 and 7, 7; and the base bars if), 16 are pivoted together by the limbs 6, 7 and paii's of pivots 12, 13, 14 to constitute a toggle joint frame pivoted to the seat 1 by the pivots 8, 9; and the limbs 4, 5 constitute swinging stay legs pivoted on the axes 8 and 9 that are in fixed relation to the seat, and two tie legs 6, 7 that are pivotally connected together by a lost motion joint or connection formed by the pivots 12 in the limbs 6 and the slots 12' in the limbs 7, and respccr tively pivoted to the stay legs 4, 5; the tie formed by the limbs 6, 7 being adapted to linear adjustment as shown in Fig. 3 when the pivots 12, 13 and 14 are in a common plane to hold the stays rigidly aslant at reversed angles relative to the seat and to each other; and are also adapted to angular adjustment to hold the stays 4, 5 rigidly extended respectively toward opposite ends of one or the other of the ties. The slots 12' allow the lost motion joint of the ties to pass the alined position shown in Fig. 3 Ko as to conform to the comb of a roof as shown in Fig. 6, or to the side of a roof as in Fig. 5.
The jaws 24 arc shown spaced apart from the seat 23 sufficiently to allow the bottom flange 32 of the pail to be inserted between the jaws 24 and the seat as indicated in Figs. 3, 4 and 5, so that when the pail i.s lifted by the bail 33 the seat and the jointed frame will be lifted also.
The slots 12' allow the tie limbs 6, 7 to pass the plane in which the pivots 13, 14 lie so that the frame may be brought into the different positions required for supporting the seat in a level position above various surfaces.
It is thus seen that the seat is provided with a swinging jointed frame adapted, to hang from the seat whenever the seat is uplifted and that is automatically adjustable to level, to slanting, to convex, and to concave
surfaces, alternatively according to the relative positions imposed upon such frame By gravity assisted by pressure of the hand upon the seat when the toggle joint frame is n at rest on the surface to which it is to conform.
