Application filed May 11,

This invention relates to sheet metal cans such as are used as receptacles for ashes and other refuse materials, and also to any other metal receptacle subject to rough handling in connection with heav service.

One of the objects ot the invention is to' provide a can having longitudinal re-enforce-' ments on its sides and an annular re-enforcement at its base, in addition to the bands commonly used. i

It is a further feature to incorporate with the lateral re-enforcements, resilient bars, actin as shock absorbing elements, adapted to reduce the impact of articles brought into forcible contact with the can, thus materially prolonging its usefulness and also minimizing the noise from such concussion.

Another aim is the provision ofan efii cient cushion at the base, metal clad, andcapable of limited movement whereby the shock of dropping the receptacle upon a rigid surface is transmitted only partiallyand indirectl to the rece tacle body, thus minimizing t e effect of t e shock.

-A further object is the provision of an efiicient buffer for attachment to the bottoms of receptacles to absorb the shock' of heavy im act.

ese objects are achieved b the novel construction and combination 0 parts hereinafter described and graphically delineated in the associated drawing, forming a ma: terial part of this disclosure, and in which Figure 1 is. a top lan view of a can made in accordance wit the invention.

Figure 5 is a partial longitudinal sectional view taken through one of the cushioning ribs near the top of the can.

a bottom view showing a further applicat1on of the invention.

Figure 14 is a detail part-1y in section showmg a modified form of the bufier element. he body'of a generally cylindrical sheet metal .can is designated by the numeral 10 having a fixed imperforate bottom 11, handles 12 and upper and lower re-enforcing bands, respectively 13 and 14, riveted to the body in the usual manner.

Fixed at uniformly spaced intervals on the periphery of the can body to extend longitudinally, are a plurality of channel shaped ribs 15, the cross section of which is shown in the detail Fig. 7, or 15', as in Fig. 8, or the modified form 15-',-as in Fig. 9, all of which answer. the same purpose.

The ends of these several ribs are bevelled, a

as at 16, fiat continuing portions 17 extending under the bands 13 and 14'to be firmly held against the walls of the can.

Tightly held in the channels are bars of elastic resilient; material, as 18,318 or 18", of rubber or equivalentsubstance, the outer portions of these bars extending to such distance that a line drawn from one bar to the next'adjacent will be slightly outward beyond the tangential line making contact with the body of the can, as at 19, in Fig. 1.

Thus it will be seen that if the can is broughtinto forcible contact with a flat surface, shock and noise will be efi'ectually absorbed by the cushion rib elements 15.

In the modification illustrated in Figs. 4

' and 5, the walls of the can 10 are indented longitudinally producing recesses 20, having oonvergingly inclined side walls, between which are set resilient bars 21.

The ends of each indentation taper outwardl v from below-the bands 13 and 14 to the full diameter of the can, and receive the ends 22 of the bars 21 as best shown in A plurality of studs or pins 23 having enlarged heads. are riveted into the wall material at the bottoms of the recesses, to pass through corresponding openings inthe bars to retain the same in position.

It will be understood that the side walls of the recesses act efi'ectively as strengtheningor re-enforcing corrugations, and that the rubber or likeinserts are adapted to act as buifers for the can in the manner viously stated.

. ers to a rectangular The lower band 14, in addition to being riveted, together with the annular flange 11 of the bottom 11, is enveloped between the upstanding annular walls 24 and 24' of a bulbous 100 25.

,Enclosed in the loop 25 is a rubber or like f'resilient endless ring 26, in which are set at intervals a plurality of semi-circular metal caps 27, adapted to make contact with the combined edges of the elements 10, 11' and 14 which are normally spaced therefrom, as at 28, in Fig. 6.

These several plates are held in intimate relation by rivets 29 passing through enlarged openings 30 in the several plates, permitting a moderate but limited amount of relative movement between the metal clad cushion ring and body of the can.

In the modification illustrated in Figs. 10 and 11 a receptacle 10", such as is used commerciall for the handling of milk is provided with buffers 25, similar in all respects to the bulbous loop 25, shown in Figs. 2 and 6, except that instead of entirely surrounding the bottom of the can they are comparatively short metal sections spaced apart as le s, each enclosing a resilient element 26 a apted to make contact with the bottom edge of the wall 10" of the can and held in intimate relation by similar rivets 29 passing through enlarged openings 30 in the wall of the receptacle.

The modifications illustrated in Figs. 12 and 13 show the application of similar buiireceptacle 10", right an led buffers 25 beingbused at the corners an straight sections or uifers 25 being used on the straight sides.

Instead of using semi-circular caps 27 with which the sides of the receptacle make contact to prevent wearing a move into the resilient element 26, the stu s 27 may be embedded into the resilient element as best shown in Fig. 14.

Although I have described my improvements with considerable detail and with respect to certain particular forms of my invention, I do not desire to be limited to such details, since many changes and modiiications may well be made without depart ing from the spirit and scope of my invention in its broadest aspect.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is p 1. A sheet metal can having a plurality of longitudinal ribs, said ribs bein essentially of channel shaped cross section havin convergingly inclined side members and bands at tie ends of the can confining the ends of said ribs thereto.

2. As an article of manufacture, a. buffer for the bottom of metal receptacles, comprising a resilient element, a casing for said element, parts of said casing adapted to be attached to the receptacle to permit c ntact between the base edge of the receptacle and the resilient member, metallic wear caps between the resilient member and the base edge of the receptacle, and means permitting limited relative movement between said base ed e and the resilient member.

gigned at New York, in the county of New York and State of New York, this 28th day of April 1925.
