Application September 28, 1946, Serial No. 699,??7

3 claims, (c1. 2201-36) This invention relates to receptacle .closures and particularly to pedal mechanism foroperating such closures.

Metal receptacles of the kind familiarly employed domestically in kitchens and the like for reception of garbage and other waste materials are conventionally provided with hinged cover elements or lids and have pedal means whereby the cover maybe raised and lowered by foot operation. Devices of this kind in the prior art usually operate in such manner that foot pres.1 sure raises the cover or lid and removalogf foot pressure permits Ithe lid to close. In prior art devices of this class no provision is made for retaining the lid in an 4open position and this can be done only by manually grasping the open lid or by maintaining foot pressure on the operating pedal.

According to the present invention, means are provided whereby foot pedal depression opens the lid and the lid remains in open position when foot pedal pressure is removed. Further, arrangement is such that a subsequent depression of the pedal with the lid `in `open position causes the lid to be closed. In this way the lid may, whenever desired, Abe `maintained in open `position without any special manipulation Vaniwith- `out the necessity vfor retaining foot pedalpressure.

Whenever the `two-stage `pedal .operation is not desired, the pedal maybe used toloperate the lid in conventional manner without retaining the cover inopen position by merely restraining the degree oi pedal `depression to a less vamount than that required to .move ,the cover to opened retained position.

Conventional receptacles of the class hereunder considerationare cylindrical and therefore lid operating pedal `:mechanisms must adapt themselves to such constructions. In anyeve'nt, space limitations are such `that `preferred.pedal mechanisms comprise a lever extending"from front to rear ofthe device beneath the usable receptacle space, with an operating pedalat `the front end of the lever and avertically disposed link extending from the rear end of the lever tothe lid hinge structure. By disposingsuch single vertical link exteriorly of the confines of the receptacle, a simple and practical construc-` tion is achieved.

Several novel mechanisms for accomplishing the aims of the present invention are set forth in the following specification and are illustrated in the accompanying drawings by way of example, but it is to be understood that `the scope of the present invention is not limited thereto or otherwise than as dened Vin the appended claims. Various mechanical modifications and adaptations of 4the'illustrated mechanisms will occur to those skilled in the art, within the scope of the present invention.

Lid .I6 hasnxedrto `its rear .portion ahinge elementi() 4as.rbyimeans `of `aflange .3i :formed on the hinge elementgand weldedA or otherwise fixed to the interior of-lid I6, aszappears clearly from Fig. 2. Hinge element 30 further comprises an inverted U-shaped portion 33 and an end 1 flange 34 Which terminates in a semi-circular curl 35.

A cooperating hinge element 40 is iixed to the outside of casing l and includes a pair of spaced parallel flanges 4I and 42. The anges 4| and 42 are provided with inwardly formed

bosses

43 and 44 upon which the curl 35 bears concentrically. The outer edges of flanges 4| and 42 are arcuate concentrically with the axis of

bosses

43 and 44 and curl 35 and lthe inner surface of the web of channel portion 33 of the movable hinge element rides against the arcuate portions of flanges 4| and 42, thus :cooperating with curl 35 and confining hinge velement 30 and lid I6 to purely pivotal movement in all normal operating positions of the mechanism.

The manner in which hinge elements 30 and 3| are assembled is of no' concern here and forms the subject of my co-pending application of even date herewith.

A pair of flanges 5| and=52 may be struck from the web of channel portion 33 of movable hinge element 3|] and a cotter pin 53 or other convenient means for providing a pivot fulcrum extends through flanges 5| and 52. The upper end oi link 24 is enlarged to provide a rounded nose portion as at 55 and provided With a slot 56 through which cotter -pin 53 passes. VSlot 56 appears best in Fig. 3. At a point somewhat below slot 55 link 24 is provided with a xed laterally projecting pin 58. The numeral 60 designates a cam plate which is disposed adjacent the upper end of link 24 and has upper and lower slots 6| and 62, the former engaging over cotter pin 53 and the latter for receiving pin 58 of link 24; When the lid I6 is closed as in Fig. 2, cotter'pin 53 rests inthe upper end of slot 6| of cam plate 60, `iust as it does in Figs. 3 and 4.

Beginning with theparts in the position illustrated in Fig. 2, depression of the treadle 2| by a user causes lid I5 to open by pivotal movement about the

bosses

43 and 44. This movement is produced by engagement of the upper end of link 24 against the under side of the web of channel portion 33 of hinge element 30. vsure and con-sequent upward movement of'link 24 moves lid I6 randits hinge element 36 to the position illustrated in Fig.` 3. During this movement, cam plate 60 moves upwardly bu-t to a lesser 4degree than the upward movement` of link 24,

cam plate 60 being moved upwardly only by engagement of cotter pin 53 against the upper end of slot 6|.

" YThis relative movement causes pin 58 of link 24 to ride upwardly in slot 62 of cam plate 60 to the position illustrated in Fig. 3, and the arcuate movement of cotter pin 53 about the axis of bosses 43v and v44 during this phase of the operation moves an upper nose portion 65 of cam plate 6|] over hinge curl as shown in Fig. 3. At this point, lid |6 and its hinge element 30 are approaching their upper dead-center position. At this time lever 8 has reached its limit of counterclockwise movement, and the operator will naturally remove his foot from treadle 2| whereupon spring 26 urges the treadle2| to raised position and moves link 24 downward.

Cam plate 60 cannot accompany link 24 in this downward movement .by reason of the engagement of nose 65 thereof over. hingefcurl 35. Be-

This pedal pres-y cause ofthe relative angulari-ty'ofy slots 6| and 62 of ncam plate 60,.downward movement of link 24 from the position of Fig. 3, with cam plate 6D I held against accompanying downward movement,

causes cam plate 60 to be pivoted in a clockwise direction, such pivotal movement being generally Vabout hinge curl 35-as a pivot axis, which projects nose 65 of cam plate 60 against the inner face of the web of channel portion 33 of hinge element 3|) and moves lid |6 over center to fully opened position as shown in Fig. 4. This pivotal movement causes pin58 of link 24 to enter a lateral extension 'I0 of slot 62 of cam plate 6|), as shown clearly in Fig. 4. This engagement of pin 58 in the extension 10 of slot 62 locks lid VI6 in open position. A A

When it is desiredto again close lid I6, a second depression of operating pedal 2| again raises link 24, cam plate 60 being now raised therewith by reason of the engagement of pin 58 in slot extension 1U. During this movement a cam surface 12 formed on cam plate 60 abuts hinge curl 35 and causes the upper end of link 24 and cam plate to move to the left as a unit,-as viewed in Fig. 4. This Yexerts a counterclockwise pull upon cotter pin 53 which pivots lid 6 toward closed portion. Fig. 5 sho-ws the position of the parts when treadle 2 I is again fully depressed, and at this point the operator will naturally remove his foot from the pedal which permits the cover to fully close.

VAs pedal 2| raises during this phase of the operationl and link 24 lowers, the parts move from the position of Fig. 5 to the position of Fig. 2. Toward the end of this movement, the lower lefthand corner o-fV cam plate 68, as viewed in Figs. 2 through 5 engages against the side wall of casing I5, which pivots cam plate 60 sufficiently to free pin 58 from engagement in lateral extension 10 of slot 62, whereupon the mechanism is again in the position illustrated in Fig. 2 for a subsequent lid opening operation.

Fig. 7 shows a modification of the upper end of link 24 which comprises a substantial downward extension 15 of a nose 'I6 which otherwise corresponds in function to the nose vof link 24.

Having in mind that the construction of Fig. 7 includes an identical cam plate and identical hinge elements 38 andu4, the only difference being in the presence of downward extension 15, when the rapidly moving cover is thrown to its fully open position with pressure removed from pedal 2|, the downward extension 'I5 engages securely over hinge curl 3'5 and lock-s the cover more securely in open position.

The modiiicaton illustrated in Figs. 8 through 12 will now be described. The general operation of the mechanism of Figs. 8 through l2 is similar to that of the rst-described embodiment. This embodiment comprises a hollow cylindrical casing and a lid or cover element 8|, the former having fixed thereto a hinge element 82 and the latter having fixed thereto a cooperating hinge element 83. The

hinge elements

82 and 83 maybe identical with the

hinge elements

40 and 30, respectively, of the first-described embodiment.

Referring to Fig. 8, a rigid cross bar 35 xed in casing 80 supports an operating lever 86 which includes a pedal portion 81 at one end and a pivotal .connection with an operating link 88 at its opposite end. In this form, the force of gravity acting upon the parts sufficiently biases the mechanism to pedal-raised position without the need for spring means.

The upper end of link 88 has an arcuate slot 90 which terminates at its upper end in a downward extension 9|. Like hinge element 30 of the first-described embodiment, hinge element 83 has a pair of down-turned ears 95 which form bearings for a pivot pin 96 which may be in the form of a cotter pin as previously described. The upper end of link 88 is disposed between the ears 95, and the slot 90 therein receives pivot pin 96. Below slot 9|) link 88 is provided with a cam surface |00 which is engageable against a hinge curl |0|, similar to the hinge curl 35 of the preceding embodiment, in a manner which will appear from a description of the operation.

The force of gravity normally biases the upper end of link 88 to the right as viewed in Figs. 8 through 12, so that pin 96 is normally above the downward extension 9| of slot 90 when the parts are in the lid-closed position illustrated in Fig. 9, wherein pedal 87 is fully raised. When foot pressure is applied to pedal 8'|, link 88 raises and the slot extension 9| engages pivot pin 96 and raises lid 8| to the position illustrated in Fig. 10 when further continuous pedal depression is arrested by engagement of cam surface |00 against hinge curl |0I. The natural tendency, since further depression is not possible, is to remove pressure from the pedal 81. When the parts have reached the position of Fig. l0, lid 8| and hinge 83 thereof have passed their dead-center position so that release of pedal pressure, which permits link 88 to drop and thus release pivot pin 96 from slot extension 9|, permits lid 8| to fall to a more open position as illustrated in Fig. l1.

It will be noted that in this movement from the position of Fig. 10 to the position of Fig. 11, link 88 lowers only momentarily until pivot pin 96 is in the upper end of slot 90, whereupon the further opening movement of lid 8| actually again raises link 88 until further raised movement is arrested by a second engagement of cani surface |00 against hinge curl |0| as shown in Fig. 11. At this time lid 8| is in its fully opened position. However, since pivot pin 96 is now freed from slot extension 9 I, it is now possible to apply additional pedal pressure and further raise link 88, to thus effect closing of lid 8 When such closing pedal pressure is applied, cam surface |00, during raising movement of link 88 cams against hinge curl |0| and thus forces the upper end of link 88 to the left and, by reason of the engagement between pivot pin 96 and slot 90, rotates the lid in a counter-clockwise direction toward closed position. When the pedal has reached its fully depressed position, the hinge parts and link 88 will have reached the position illustrated in Fig. 12, wherein link 8| has returned back past dead-center and will be fully closed by gravity upon release of pedal 81. the parts automatically returning to the position illustrated in Fig. 9.

What is claimed is:

l. A receptacle and a cover therefor, each having zzo-operating hinge formations adjacent an edge of said cover, said cover having pivot means eccentric with respect to said hinge formations and inwardly thereof relative to said cover, an upright link having a slot adjacent its upper end for engagement with said pivot means, said link being operable by upward movement thereof to move said cover to gravity-retained fullopen position, said link having cam means projecting outwardly from one side thereof carried thereby and engageable against one of said hinge formations when the cover is in raised position, whereby a subsequent upward movement of said link cams the upper end thereof laterally whereby its slot acts against said eccentric pivot means to cause the cover to be swung toward closed position.

2. A receptacle and a cover therefor, each having a cooperating hinge formation adjacent an edge of said cover for pivotal movement of said cover between open and closed positions,

`cover operating means comprising a vertically movable link, said cover means having an eccentric pin and said link having a pair of connecting downwardly diverging slots for receiving said pin, the slot nearest the receptacle being positioned to engage said pin and raise said cover upon upward movement of said link, said cover being arranged to fall over center to full-open position upon release of said link and thereby move the eccentric pin into the other of said slots, said link having an inclined cam formation engageable against a relatively fixed portion of the hinge structure when the eccentric pin is in said other slot whereby subsequent raising of said link causes the cam formation to move the link laterally toward the receptacle and thereby cause said other slot to act laterally against said pin and move said cover toward closed position.

A receptacle and a cover therefor, each having a cooperating hinge formation adjacent an edge of said cover for pivotal movement of said cover between open and closed positions, a pin on said cover disposed inwardly of said hinge connection when the cover is closed, cover operating means lcomprising a vertically movable link having a slot engaging said cover pin, a cam plate likewise having a slot connection engaging said cover pin, the slots in said link and said cam plate being generally upright to provide a vertical play connection therebetween, a second pin and slot connection between said link and said cam plate spaced from the beforementioned pin and slot connections, the slot of said second pin and slot connection being disposed to cause relative lateral movement of the cam plate upon downward movement of the link relative to the cam plate, said cam plate having an outwardly projecting cam surface for engagement against one of said hinge formations upon said lateral movement of the cam plate, means on the cam plate and engageable with the hinge formations for retaining the cam plate in elevated position when the cover is raised and the link moves downwardly, whereby an initial upward movement of said link Lopens said cover by abutment thereagainst of said link and said cam plate and a subsequent upward movement of said link closes said cover by engagement of said cam surface against said hinge formation.
