TANK.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed April 22,19074 Serial No. 369,609.

walls thereof with a terminal circumferential tube or bead which not only increases the rigidity of said walls but also forms a smooth bearing surface for the upper orfree edge of the tank.

A still further object of the invention is to generally improve this class of devices so as to. increase their utility, durability and elliciency.

Further objects and advantages willappear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accomjuinying drawings forming a part of this specification: l41 igure l is a vertical sectional .view ofy a. tank constructed in accordance with my invention. Fig. l is a side elevation partly in section of a portion of the upper part of the tank.

Similar numerals of reference indicate corresponding parts in all of the iigurcs of the drawings.

The improved tank forming the subject matter of the resent invention is preferably cylindricalin sliap'c and formed of sheet metal or other suitable material, said tank having an in'ipen'foratc bottoni 5 and verticallyT disposed sidewalls (i connected with the bott-oni 5 by a lap joint 7.

Secured Ato the upper or free edge of the vertical walls 6 is a circumferential rcinforc ing tube or bead 8 having a recess 9 formed in the bottom thereof andY adapted to receivethe adj acont edge of the tank thereby to reinforce and strengthen the walls of the tank and. also form ajsmooth bearing surface at the upper edge of the latter.

Disposed within the tu be S at the meeting ends l() is a sleeve or collar 11 also provided with a slot 12 for vthe rece )tion of the upper edge of the tank, said sleeve or coupling member being so arranged as to overlap the ends l0 of the tube 8 andA thus form a rigid como ection between the saine.

Embracing the exteriorwalls of the tube 8 at the meeting ends 10 thereof is aclamping member 12 prefcrabl formed of a single piece of metal the lower longitudinal edges of which are bent inwardly to forrnattaching lianges 13 which bear against the interior and exterior faces of the adjacent vertical walls 6 and are secured thereto in any suitable manner as l'by bolts, rivets or similar fastening devices 14.

The clamping member 12 is further secured in position on the split tube 8 by means of transverse bolts or rivets 15 whichl extend through the clamping m'ember 12/ and coupling member 11 and also ierce the adjacent portion of the vertical wa l 6, there being similar bolts or fastening devices. 16 disposed at spaced intervals around the split tube and extending transversely through the same and through the walls of the tank thereby to securely fasten the split tube in position on the top of the tank.

Soldered, riveted or otherwise rigidly secured to the lower portion of the tank is a reinforcing band or hoop 17 rovided with-a lateral offset portion 1S whic i forms a casing or housing for the connection between `-the bottom and side walls of the tank so as to prevent injury to the latter. One edge of the band or hoop bent in engagement with the side walls of the tank to produce an.

inclined shoulder 16 while the opposite edge thereof is extended laterally beneath the bottom of the tank to form a reinforcing ring 19 which also serves to receive and sustain the weight of the tank and prevent undue wear on the bottom thereof.

Having thus described the invention what is claimed is:

1. A tank having its upper edge reinforced by a split tube, 'a cou )ling member engaging the interior walls of tile tube at the abutting ends thereof, and a clamping member embracing the exterior walls of 'the tube and l having its opposite longitudinal edges spaced apart and secured to the interior and exterior walls of the tank.

.2. A tank having its upper edge reinforced by a split tube, a cou )ling member engaging the interior walls of the tube at the abutting ends thereof, a clamping member embracing the exterior of the tube and having its adjacent ends bent laterally to forni attachin fianges for engagement With the interior an exteriorvwalls of the tank, res ectively, and

'fastening devices piercing said flanges..

3. A tank having its upper ed e reinforced .by a split tube, a tubular cou ing member engaging the interior walls of t le tube at the abuttin ends thereof and provided with a. iongitu inal slot for the reception of the `Vertical Wellof the tank, a clamping member clamping and couplinvmembers and piercing 10 the vertlcal well of t e tank.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
