Application filed. October 16, 1926. Serial No. 141,909 7 relates to devices for redoors to receptacles, and

The invtuition movabl i' secin'in whit-lithe door is subjected to impact, such, t'or example, as the doors to tumbling 1eceptacles.

'lfhe object of the invention is to provide an improved dew-closure "for a receptacle of this type which, is readily operable to secure or release the door, is adapted to force the door and the receptacle together, and is adapted to reinforce the door when 1t closed so that it will be securely held aginst ale-torn won by impact of the material in the revolving receptacle. 7

other object ot the invention is to proa closure of this character which is simple in construction, permits the door to be readily and completely removed and rephnked and is cilicient in operation The invention consists in t ne several novel 'ieaturcs hereinafter set forth and more particularly (it-dined by Claims at the conclusion hereof.

in the drawings: Fig. l is a section of a cylindrical ieceptacle equipped with the invention. Fig. 2 is a plan. Fig. 3 is a section taken on line il-2% of Fig. 2. Fig. 8 is a detail perspective of one of the toggle-links. Fig. 3 a perspective of one of the lugs t'or pivotally holding a toggle-link on the receptacle. Fi 4 is a plan of the invention applied to a rectangular receptacle. l f; is is, View partly in section and partly in side elevation of the closure shown in (5 is an end view of the con- 1- iown in .ln lfiigs. i to 3 the invention is rem-pli- .ied with :1 tumbling receptacle or drum A which has a cylindrical body A. which is iovided with an opening a through which w nmterial and the articles to be treated ire-red into and discharged troin cle. An arcuote door B is pro said inpcning and comprises ate wall Z lilting in the openn outer liner Z) having its mard to lap the wall of the receptaat the margins of said opening. to the inner face of the i -hoily, at the margins of the opencrve as stops for the inner face of wall i3 and reinforce the receptaat said margins.

Each closing device con'lprises a pair of alignal transversely extending adjustably connected complementary members or bars in which are removable with the door and a pair of togglelinks l) pivoted to the outer ends oi? the members respectively and adapted for detachable connection to circumierentially aligned brackets C on the rece iitacle-body. Each bracket O has a base 0 riveted or otherwise suitably secured to the outer periphery of the receptacle-body A adjacent the margins of the door, and a pair of integral outwardly opening hooks with a space between them. Each link i.) has its distal or outer end adapted to lit into said space and an opening a in the base 0 of one bracket- Chand has oppositely projecting integral studsor lugs (Z adapted respectiveh to enter and seat in the hooks a on one oi the brackets C. The other end oi each linlt D is piv-otally eonnectedby a pin (Z to the outer end of one of the cross-members E. .lach member E cornprises a transversely curved or arcuate basewall (1 extended at e to abut against the central portion of the door and at e to abut against the marginal portion of the door over the opening and over the portion of the door which laps the receptacle-body; pivot-lugs at its outer end in which pin held and between which the toggle is confined longitudinally oi? the receptacle; side-walls 6*; and an inner end-wall e having an opening a therein; all of the ele ments of the member being integrally formed. Each member E is held in connet-ted and transversely slidable relation to the door by a stud e which is riveted to the door and extends through an elongated slot e in base-wall e, anda nut a threaded to the outer end of the stud. A sleeve 6 around the stud and confined bet-ween the liner Z) of the door, and a washer e on the stud limit the nut so the member will be free to slide around and on the outer face oi the door. The adjustable connection between each complementary pair ot men'ibers E consists of a bolt/l with a shankj' eX- teinliug through the openings e in the inner end-walls of said members, a head f" on one end of the bolt engaging the end-wall of one member, and a nut f threaded to the other end of the bolt. By turning the bolt relatively to the nut f the members maybe drawn together by bolt-head f and nut F.

A wusherorclip f is; non-rotatably confined the relative movement between the nienr hers so the bolt cannot be turned to subject the door to excessive inward stresses.

Several of these closing; devices are ueual- 1y applied to hold a door, the number acipendingnpon its lengtln but since they are alike in construction, only one has been ehown and described. The receptacle is provided with trunnions 7.2 on its ends which are jonrnalled in suitable Stationary bearings (not shown) so the receptacle will he rotatable on its longitudinal axis.

Bolt f will then he turned so its head j and nut 7" will draw the inner ends of the members E together, This will cause the togglelinlts to pivot in their seats in hooks 0 their other ends and pivot-pins (P will Iswiug inwardly nnd towards the wall ot thereccptnele and door. The slots o perinit the members to slide im *ardly around thedoo as the bolt is ti glitened, and use result, the ributinents o oi the members will force the lapping portions of the nnirginsot' the door inwardly against the lapped portions of the receptnclwbmiv so that the lapped portions olthe door and reeeptaelo will be firmly jammed togetlior to form a tight closure. Sinndtaneously, the inner ends oi? abutments and fllltllll'lltfltfi a will he drown against the outer periphery of the door to reinforce it against internal impact intermediate and at its ends. d hen the door is thue secured. the rlosure-dwires will Secure it so it will be retained 11:43]! integral part out the receptacle, and will be Well adapted to Withstand the import stresses to which it is suhjected when the receptneleis rotatedin the tuiuliilingr operw tion. I v

In the modified "form of the invention shown in Figs. i, :3 and (3, the improved elosure is applied to areotangnhir rereptacio comprising a body with sidewalls (/9 and having one side o 'ien. The door 13 is fltltt]'.)tedto oloee the open side and to lap the edges otthe side- Walls o Angle-iron hnrs o are secured to thesides o and are formed with irotehes o to receive the etuds d oi togglehnks D; the studs being adapted to extend under the horizontal flanges of the bars so that they will he held in hooked. engagement with the receptaelehody. Pins (Z20 pivotnlly connect the links to the outer ends ot' the members E respectively. .llaeh member is provided adjacent its outer end with an nbutlnente to bear against the outer inee oi oneniargin of door l3 and an nbutnient a? at its inner end to boa r against the intermediate port-ion of the door. Each member E also comprises a base-Wall C1227 sides 0 and an inner end-wall 0 A bolt I similar-in construction to the bolt I? 0." tends through holes in owl-walls t and pro *ided with :1 head I and a looked not 7" adapted to drain the members It together. Studs 6 which are riveted to the door ll extend through eloti; (9? in the nienihern E respectively and are provided with nuts e" and sleeve 6 forming sliding conned tions between the members and the door It. When the bolt F is turned in. one direction. to draw the inner ends thereof together; the pivots (Z of to l links I) will i-xwinn; inwardly about studs (6, thus causing the abutment 0" to force the outer end: oi' the members against the edges ol the side? o'" of the receptarle, and sinmlteneoiealy, the idiotinents i1 will be forced inwardly no that. the inner ends of the illtlll'llletti will brace-e or reintorce the central portion of the door.

In either of the terms oi the inrentimi shown, when it is desired to obtain new i to the receptaole, it is only neeossnrv to turn the bolts to permit the inonihers to spread until the toggle-links D can he sorting out of engagement with thehoolm on tho rwelutarle body.
