AUTOMATICALLY-ADJUSTABLE BASE.

Application. filed February 20, 1923. Serial No. 620,145.

This invention is. especially adapted for use as a base for supporting paint buckets,

and the like, to keep thesame level on i11 clined surfacessuch asv roofs and the like and on convex and concave surfacessuch for instance as on the outside or inside "round ing surface of a large pipe, drumouglobe.

An object of this invention ,,is to facilitate the use of paint bucketsandother open top containers on roofsand other non-level surfaces; and the invention is broadly new,

basic'and pioneer in that I provide avessel holder with a loosely jointed toggle like supthe same is supported by hand independently of any other support, and adapted to conform by ts own weight to such surface as it may be lowered onto, and to retain the position at whichthe vessel holder is brought to rest, irrespective as to whether it bethe side or the peak of a roof or in avalley 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 against accidental displacement. or tilting on the base, and which is constructed to prevent any slipping of saldb'asje on the surface on which it may be placeda Another object is to provide forinclined 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 each placing of said pail.

Another object is to provide for pails and other receptacles, a baseto which the receptacle may quickly" and easily be attached and as quickly and easily detachedpwhen de' sired.

the pail and base may be lifted bythe hail of the pail and carried from place to place without disengaging the pail from the base.

An advantage is that the base is antislipping so that its use enables the work men to leave the surface from which 1t has been removed, free from nail holes.

The invention is adapted to be used by other mechanics and builderS;,, being suitable for use by shinglers to hold their shingles or to sit on, or by tinnersto supporttheir fire pots; and by brick layers to hold brick or An object is to make provision whereby casion.

Theplatform orrigid seat l 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 afdjusted.

b'ects advanta es and features of The accompanying drawing illustrates the" pail being brokencomprising 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 pivot ed to the mm 4, 4 and the braces 5, 5 being pivoted to the ears 5,5." The limbs 6, 7, ofthe ties are each approximately equal in length to the spacebetweeii centers of their pivots 8, 9 that connect them with the ears 4', 5 that are secured to the platform 1 or seat bythe rigid strips 10 and 11 so that the seat is 'rigidand the pivotal axes at 4 and 5" are held' in parallelism.

The long limbsfi, 7 are connected together by 'a lost motion pivotal connection at 12, and are "also pivoted at 13,1410 the short limbs 4, 5 and to therigid 'base'bars 15,

16 which are'tiirned up at the ends to form ears which base bars and their pivotal axes 13,: 14 'a'iidthe pivotal avis 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 ofinsuring the toggles against collapse. Spurs IQ-are provided onthe underside of the seat to engage the roof'in case the base is placed on theinclinled surface of such roof. Said spurs are "preferably formed of the down-turned ends ofa strip or bar'2Qof metal, applied directly beneath the jstrip 11; said ,endsbeing pointed to form the'spurs 19. l Rivets 21are used to attach both the strips 11 and 20 to the seat 1.. Said spurs 19 m of a length to merely catchjin'to the roof snfiiciently to retain the base on the slanting 'surface of the .roo'flas shown in Fig. 5 when' si eh roof is composed of shingles or any penetrable material not likelyto be injured by the sp'urs. 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 cases where the use of spurs mi ht prove inju'riousas on roofing or the like, such provision being 'a strip 22 of rubber attached. to the underside of'theseat 1"at theedge opposite to that near which, the spurs 19 are placed; said strip 22 extending flush with or 'a trifle beyondjthe edge 23 of. the platform. Fig. 8 shows in dot and dash lines'the positionof the base in such en gagement Thusifthe base may be turned at pleasiire to engage, at either edge with the roofa'spccasion requires. It is seen that in a balanced.:position as shown in Figs.

- 3 or 6th efretain ersf19 and, 22are not .re

quired and are out of the'wayj 2. 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'se'chwith a rectangular receptacle.

Said jaws 0r 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 slidcways 30 while the other ends of the slides 25 are pivotally connected by the links 26 to the lever 27; said lever being pivoted at 31 to the platform 1 and 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 are arranged in pairs, as the stay legs 4, 4 and 5, 5; the tie limbs 6, 6 and 7, 7; and the base bars 15, 16 are pivoted together by the limbs 6, 7 and pairs of pivots12, 13, 14 to constitute a togformed 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 0X- tended respectivelytoward opposite ends of one or the other of the ties. The slols12 allow the lost motion joint of the ties to pass the alined position shown in Fig. 3 so as to conform to the comb of a roof as shown in Fig. 6, or to the side of a roof as in Fig.

The jaws 24 are shown spaced apart from the seat 23 suiiieiently 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 is 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 adaptedto 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 at rest on the surface to which .it is to corn form.

I claim:
