To all whQm it may concern:

Be it known that 1;"Fnnn hjDin rINsoN, a citizen of the Dom nion of Canada, reslding lat l-lydro,inthe eoun'ty of Blaine and State ofjMontana, 'have'invented certain new and nseful Improvements in Collapsible Churn- .TFrames, :of

which theffollowing is a specification. I k

This invention relates .to supporting frames, and more particularly to collapsible framesfor su porting churns and similar vessels.

' The object offtheinvention is to provide ,a] si mply constructed and strong frame jof this character which may be quickly and easily set upand collapsed without theuse of tools. 7

Another .object is to provide a frame of this-character, the braces of which when in :open operative position securelyand reliably hold the frame inupright position against .collapsejand canlonly beffolded after the locking bar constituting a art of the frame is; released.

t-view,,.,\ vhich will appearas the description ?With the [foregoing and other objects in proceeds, theinyention resides in the combination; and arrangement of parts and inthe deta ls of. constructlon hereinafter descr bed and cla med, t be ng understood, that ,c flng nin-the pr i embodiment Ofth invention herein disclosed be niacie within the scope of what is cla med ,wlthout departing from; the. spirit of .thejinvention.

In thelacco npany'ing draw 1ngs:- Figure 1 represents an end vlewojf a frame constructed in accordance with this f invention withthe churn in the form of a barrel shown suspended therein in dotted lines, and frame shown collapsed in dotted lines,

Fig. 2 is aside .elevationthereof. shown in open-position ,in full lines and in partially collapsedposition indOtted lines, the churn .being shown supported in said frame in .dots and dashesfand ,F i g. 3 represents :a detail perspective iew .of onetof the bearings which supports the churn with the partsthereof arranged in jnxtaeposition readyafor assembling.

In the embodiment illustrated, the frame constituting thiSziIlVBHfiQIl is p efe ably. constructed pf; angle iron and comprisesitwo A- shaped end members .1 and 2, the crossbar ,8 ofwhichis composedoftwo sections 4. and

"'5 pivotally connected as shownat 6 anti with their outer ends pivotally connectedto the s debars S and 9 of the frames 1 and 2.

flIhe pivotally connected ends of these sectlons 4 ando are arranged 1n lapplng relation with the horizontally disposed flange of one section cut awayat its pivoted end as shown at 7,1the edgeof said cut away portlon be ng overlapped by thefiange'? on the other section so that when these sections are arranged in longitudinal alinement as shown in Fig. '1', 'theoverlapplngflange 7" will operate to hold the sections rigidly against furtherfldownward movement and yet permit the sections to open npwardlyinto folded position when the frame isto be collapsecb The sidebars 8 and'9 of these A shaped frames areprovided at their lower ends with laterally extending surface engaging plates J10 and at their upper ends which are piv otajlly connected with pint le receiving'bearugs 11 which are made n the form of sections 12 and 18 onecarried by one side-bar and the .otheriby the other side bar and each having complementary hinge knuckles 14E fer hingedly connectingbars 8 and'9 and .also the bearing sectionsrl2 and '13. These bearing se tions are secured'to the side bars 8 and f9 byriveting orin any other' suitable manner and are provided at'th'eir upper ends V with re istering semicircular grooves 17 1 which formwhen t hese sections are brought together, a bore 718 to receive one of 'jthe pintles 19 of the churn or other vessel O to be suspended withinthe frame.

It is to beunderstood that thesej A shaped send membersare constructed esactlylalike and hence one'only has been described. in d al The end members, 1,.and2 of each frame are connected by diagonally disposed braces 20 and 21 which are'preferably composed of angle iron, each haymg a laterally extending flange. along one, side edge'thereof as is shown clearly, at 22 in Fig. 2. Each of these'braces is pivotally connected at its opposite ends with .one of the sidebars of; each end member 1 and '2 and one of said braceshas'its .endsdisposed on the outer face of saidb ars while the other is disposed 011 their inner faces asis' shownclearly in ,Fig.' 2 withthe flanges 22 ofsaid'braces, one extending out- Qwardlyandthe other inwardly so that the tflansm oth "f e .ofthesebrace il b dis I and 15 through which thepintle'16 ispas sed posed adjacent each other and avoid unnecessary spacing thereof. As shown in Fig. 2, brace is pivotally connected at its lower end with the inner face of the side bar 9 of the end member 1 and at its upper end .is pivotally connected with the inner face of the side bar 9 of the other end member 2' while brace 21 is pivotally connected at its lower end with the outer face of the side bar 9 of member 2 and at its upper end with the outer face of the side bar 9 of member 1, said upper brace ends being'arranged adjacent the upper ends of said side bars so that when the frame is in expanded opera tive position it will be firmly braced throughout its height.

Each of these braces 20 and 21 is cornposed of two pivotallyconnected sections as 23 and 24, the connected endsrof which are arranged in overlapping relation in the same manner thatthe section ends of the cross bars 3 are connected, the flange 22 at the inner end of one section being cut away and that of the adjacent end overlapping the cut away portion so thatwhen the brace sections are in longitudinal alinement, this overlapping flange will operate to hold the braces against further downward movement.

It will thus be seen that when the braces 20 and 21 are in open operative position as shown in Fig. 2, and the sidebars 8 and 9 have been expanded and held in open position by the cross bars 3 as shown in full lines in Fig. 1, the frame is in position for supporting the churn barrel C- or any other vessel to be supported thereby. In order that this churn may be mounted in said frame, the bearing sections 12 and 13 are separated to receive the pintles 19 of the churn by first breaking the joints of the cross bars 3 and moving the side bars 8 and 9 of the two A-shaped members toward each other a sufficient distance to cause the bearings to open at their upper ends as shown in dotted lines in Fig.1 and when in this position the pintles may be lowered into said bearings and the end members opened up into the position shown in full lines in Fig. 1 whereby the bearing sections 12 and 13are closed around said pintles and afford a firm support for the churn.

After these members have been so positioned they are locked against collapse by means of a cross bar 25 which is pivotally connected at one end with the lower end of one of the side bars of the A-shaped member 2 and has detachable engagement at its other end with the corresponding side bar of the A-shaped member 1 as is shown clearly in Fig. 2. In this figure the cross bar-25 has its free end inturned to form a hook 26 which is engaged with a slot 27 formed in said bar 9 of member 1 and when this bar 25 is so positioned, the frame is held against collapse and can only be folded after lifted from said frame and deposited at any suitable point. The further collapse of the frame is accomplished by bringing the lower ends of said bars 8' and 9 of thetwo sections into contact with each other and then breaking the joints in the sections ofthe'bra'ces 20 and 21 and folding said braces upwardly as shown in dottedlines in Fig. 2, the folding being continued'until said braces are in completely folded position and when in this position, the braces 20 will be housed within the bars of the end members while the braces '21 will be disposed on theouter face of said bars and lie in close proximity thereto. It will thus be seen that the frame when so c0llapsed willcoccupy a very small space and may be conveniently stored or shipped.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is'mere'ly illustrative and that such changes may be made as are within the scope of the claimed invention.

I claim y '1. collapsible frame including foldable end members, foldable bracebars connecting said members, and a cross bar pivotally connected at one end with one end member "and detachably engaged at its other end with the other end member whereby the frame is heldoted to fold in one direction, means for locking said sections against pivoting in the opposite direction, folding'brac'es connecting said end members, and means for locking said braces in open position;

3. A collapsible frame including 'A-shaped' end members, each composed of pivotally connected side bars with a cross bar conneotmgthem and composed of sections pivoted to fold upwardly, cooperating means on said sections for locking them in 1ongitudinal alinement against downward folding, upwardly folding braces connecting said end members, means for locking said braces against downward folding, and a cross bar detachably connecting said end members to hold the frame in operative position.

4. In a frame of the class described, a pair of A-shaped end members, the side bars of which are pivotally connected at their meeting ends and the cross bars composed of pivotally connected sections and pivotally copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

connected with said side bars near their lower diverging ends, said cross bars being foldable inwardly and held against outward folding, foldable braces connecting said end members, and means for locking said braces against folding. y

In testimony whereof I aifix my signature in presence of two witnesses.
