STOP HINGE.

Application filed March 29, 1923. Serial No. 628,627.

To all whom it may concern.

Be it known that I, JAMES P. WALKER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Stop Hinges, of which the following is a specification.

This invention relates to receptacles and particularly to a stop hinge construction for connecting the cover to the body of a waste receptacle.

The purpose of the invention is to provide a simple inexpensive construction which uides itself, is not likely to become fouled y the contents of the can, and permits removal of the cover from the can for shipment or repair with the minimum difficulty.

The invention has particular utility as applied to the type of selfclosing receptacle described and claimed in the patent to Ed wards, No. 1,238,993 and is illustrated as so applied in the accompanying drawings, in which Fig. 1 is a perspective view of the upper portion of such a can, with the cover swung open to permit the receptacle to be emptied, and hence illustrating the position assumed by the stop in the open position of the cover.

Fig. 2 is a fragmentary elevation showing the stop in the position assumed when the cover is closed.

Fig. 3 is a fragmentary section transverse to the axis of the cover hinges showing the parts in closed position.

Fig. 4 is a similar view showing the parts in open position.

In the drawings, 6 represents the body of the receptacle reinforced at its open top by a band or strip 7. A pair of alined hinges 8, whose axis is offset so as to lie outside the receptacle and below the upper margin thereof connect the receptacle 6 and its cover 9.

This cover 9 is of the gable form, characteristic of the Edwards type of can and is pressed up from sheet metal. Its lower margin, which overhangs the upper margin of the receptacle 6, is reinforced. by folding the sheet metal back upon itself as shown at 10, and then inward to form a flange 11 which stifi'ens the margin of the cover and also serves as a seating flange which rests on the top of the receptacle 6 and supports the cover. The hinge pins 12 of the hinges 8 are cotter pins so as to be capable of easy withdrawal. It will be observed that the hinges 8 are connected to reinforced portions of the receptacle and cover. These connections, as well as the connections of the reinforcing band? to the receptacle 6 are made by spot welding, a construction which leads to easy assembly and good structural strength.

A bracket 13 is spot welded to the body of the can 6 and carries pivoted thereto, by

' means of a hinge pin 14, a stop arm 15.

The pin 14 is so located that when the arm 15 is arrested by collision with the reinforcing band 7 it lies in face'contact with the band. Absolute accuracy in this action is not essential but it is desirable to approximate the result as clearl as commercial manufacture permits, as this tends to reduce bending stresses exerted on the arm and band.

An angular bracket 16 is spot welded to the cover 9 in the angle between the cover and the flange 11. It thus serves in some degree to stay the flange 11 and derives some support therefrom. Just beyond the margin of the flange 11 the bracket 16 is formed to receive a hinge pin 17. The pin 17 serves as a connection between the bracket 16 and the link 18, whose other end is pivoted by the cotter pin 19 to the free end of the stop arm 15.

The cover 9 is formed with an opening which is closed by a pendant gravitating closure 20 pivoted at the ridge of the gable as shown at 21. This closure has two inclined surfaces conforming to the sloping surfaces of the gable, and is tipped bodily in either direction from its normal position when material is to be deposited in the can.

The stop structure is thus simple, strong and, selfguiding. In the closed position of the cover it swings down rather close to the side of the can so as to be out of the path of refuse delivered into the can. Furthermore, this type of stop has no tendency to become entangled with the bag (not shown) which commonly is suspended within cans of this type to receive the refuse.

What is claimed is 1. The combination of a receptacle, a cover hinged thereto on an axis outside the receptacle and below the upper margin thereof; a stop arm pivotally mounted within said receptacle below the upper margin thereof; and a link pivoted to said stop arm and pivotally connected with said cover on an axis spaced from said hin e axis, the arts being so arranged that t e sto arm is arrested by collision with a portion of the receptacle, as the cover reaches open position.

2. The combination of a receptacle having a reinforced upper margin; a coyer hinged to said rece tacle onan axis. outside the receptacle and elow the upper margin thereof, said cover having an inward pro jectin flange arran ed. to seat on the reinforce margin of t e receptacle when the cover is closed a stop arm ivotall mounted within said receptacle elow t e upper margin thereof and arranged to be arrested by collision with the reinforced marginal portion of'the receptacle; and a link pivotally connected with said am and pivotally connected with said cover on an axle spaced from said hinge and adjacent the margin of said flange. I

3. The combination of areceptacle having a reinforced marginal portion; a cover of sheet material having a reinforced overhanging marginal portion formed by folding the material back upon itself and then inward to forma flange which in the'closed position of the cover seats upon the reinforced marginal portion of the can; a bin mounted on the outer side of the reinforced margin of the can and on the under side of t e reinforced marginal portion of said cover and serving to hinge the cover to the receptacle; a stop arm pivoted to the receptacle within the same and adapted to be arrested by collision with the reinforced portion thereof; a bracket connected with said flange and with the cover; and a link pivoted to said bracket adjacent the margin of said flange and also ivoted to said arm.

In testimony whereo I have signed my name to this specification.
