MAX WEBER, OF CLEVELAND, OHIO.

HINGE CONTRIVANCE.

Application filed October 7, 1915.

To all whom it may conccm:

Be it known that .1, MAX lVnnnn, a citizen of the United States. residing at 1201 Starkweather avenue, in the city of Cleveland and State of Ohio, have invented a new and useful Improvement in Hinge Contrivances, of which the following is a specification, the principle of the invention being herein eX- plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention in hinge contrivances relates more particularly to that type of structure commonly adapted to support a screen door which it is desired normally to have closed with some positive assurance other than a spring control for the assumption of such position. As such my invention in volves a pair of pivotconnections so arranged as to bring about a gravitational return of the door-to its closed position.

I am aware that the broad idea of having a door become tilted upwardly upon its pivots when the same is moved through an arc of ninety degrees is known to the art, and further that such result was accomplished by having the lower part of the door forced away from the casing when the door was swung into a plane at an angle to the latter.

Accordingly this invention in hinge contrivances especially features a number of improving structural details in association with such old )rinci ale in tiltin' or 'ravithinges. My object, besides feasibility, simplicity, durability and economy of manufacture, has been to supply the advantages of accentuation, reversibility, reinforced light ness and a slight locking action, all of which, in the way of attainment, are to be herein after explained.

Vi ith the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but itis to be understood that changes, variations and. modifications can be resorted to which come within the scope of the claims hereunto appended.

Adverting to the drawings:

Figure 1 is an elevation of a door casing and a door movably supported thereon through the agency of invention.

Specification of Letters Patent.

Patented May 15, 1917-.

Serial No. 54,519.

Fig. 2 is an elevation on a line of vision at ninety degrees to that of Fig. 1 showing the door in its full open position.

Fig. 3 is an enlarged top plan of the upper of two pair of coacting members, the same being purposely reversed from that shown in Figs. 1 and 2 in order to emphasize the feasibility of so doing.

Fig. 4 is an enlarged view of the parts shown in Fig. 8 seen at an angle of ninety degrees toward the inside and with the parts in their separated position.

Fig. 5 is an enlarged bottom plan of the lower pair of coacting members likewise reversed from that shown in Figs. 1 and Fig. 6 is an enlarged view of the parts shown in Fig. 5 seen at an angle of ninety degrees toward the inside and with the parts in their separated position nd also one such part wholly sectioned and the other sectioned in part.

A door casing 1 surmounted in a door 2 includes a side upright 3 having an invmrdly disposed edge 4 in proximity to which a screen door 5 is shown fitted as si'ipported by a pair of hinge contrivances en'ibodying my invention in their operative relation to *ach other.

What 1 term the upper supporting member 6 as shown in 2 and involves a downwardly projected arm 8, the former being intended to be secured near the top of the upright 3 and the latter accordingly e:; tending a given distance therefrom. An in tegral of stif ening webs 9 are also provided across the junction of the opposite side edges of the arms 7 and 8. The arm 7 is fastened with three openings 10 under which the necessary fastening screws pass. The arm 8 is provided with a circular opening 11 of given size as appears in Fig. 3 and outwardly with respect thereto with an upwardly connected arcuatc rib 12, the locking purpose of which will in due time be explained.

. T he other of the upper coacting members is Hat and designated with the numeral 13 and as also appears in Figs. 3 and 1 it comprises along one edge a pair of substantially transverse ears 14 which are intended to abut that edge surface of the door 5 which is opposed to the edge 4: of the casing. The portion 13 is in fact intended to be fixed near the top of the screen door by means of screws (not shown) passing through a series of openings 15 therein. The spacing of the portion 13 from the top of the door should be assumed as properly selected with reference to the distance that the member 6 is spaced from the top of the casing 1. Extending a given distance from the part 13 is an integral tubular arm 16 provided with a T shaped tubular extremity 17, the diameter of which is purposely less than the diameter of the opening 11 whereby either end of the portion 17 may be loosely pivoted in such opening. A stiffening bar 18 is fitted within the arm 16 and may or may not project a slight distance into the portion 17. This bar is seen in Fig. 3. Then one of the ends of the portion 17 is inserted through the opening 11 it is obvious that the arm 16 may rest upon and when moved ride over the rib 12 and furthermore, because of the termination of the ends of the latter at the points shown, may slip off the same to cause a slight looking beyond each of such ends when the door is in either one of its two extreme positions. The other or lower supporting member 19 is with one eX- ception of similar formation as the member 6 to comprise a downwardly projected arm 20 and a horizontally projected arm 21 reinforced by corner webs 22. Likewise, the arm 20 is fashioned with a plurality of openings for the insertion of securing screws. It should be particularly noted that the arm 21 of the lower supporting member is longer than the corresponding arm 8 of the upper of the two supporting members such that its pivoting opening 2 1 may be disposed outwardly a greater distance from the casing 3 than is the opening 11. An arcuate rib 25 similar in every respect to the arcuate rib 12 is fashioned on the upper surface of the arm 21 outwardly adjacent to the opening 24.

A correspondingly flat shaped portion 26 of the coiiperating member of the lower hinge contrivance similarly has a pair of ears 27 and screw openings 28. It also has integrally projected therefrom a tubular arm 29 with a corresponding T shaped 1101- low end 30. A reinforcing rod 31 is seen fitted within the arm 29 which latter is moreover purposely longer than the arm 16. It should be understood asFig. 5 discloses that either one of the ends of the portion 30 has a loose pivot fit in the opening 24 and it is furthermore manifest that by reason of the greater length of the arms 21 and 29 a double accentuation is effected in the way of upward tilting of the door upon its pivots when these two assume a common direction of projection. The loosening of both pivots readily permits such upward tilting thereabout without any likelihood of occasioning a binding effect. The avoidance of a binding efiect at the pivots is made the less likely by the thinness of the arms 8 and 21.

In operation the different distances that the supporting members 6 and 19 arespaced from the edge 4 allows the door to assume a true fit with the casing of the door when closed, whereas when the door is drawn open the portion 26 which is attached to the lower part of the door is shoved outwardly and this in turn so tilts the door upwardly as to insure its gravitational return to closed position.

As a manufacturing incident, the stiffening rods 18 and 81 serve a very important additional purpose of compelling a neater and stronger joint at the junctions of the arms 16 and 29 with the T shaped ends 17 and 30 respectively, owing to a reduction in the width of the spaces therebetween. This ensues because the presence of the rods 18 and 31 prevents a complete alinement of the opposed edges of the ends 17 and 30. As a further direct consequence the middle portions of those edges which are continuous become arched. each around its respective rod to project a slight distance in the direction of the parts 13 and 26 and thus more nearly close the gap which the formation by means of dies would otherwise cause to remain.

.I claim: 7

1. A hinge contrivance comprising in combination with a door and easing, a pair of brackets secured to the casing and having vertically alined projecting portions, the latter formed with openings out of vertical alinement spaced different distances from the casing, to form bearings, and a pair of arms of different length secured equal distances from the attached edge of the door and spaced apart the same distance as said brackets, the ends of said arms formed with studs adapted to have universal movement in said bearings respectively.

2. A hinge contrivance comprising two pairs of cooperating members, one of said members of one pair being provided with a socket and, an arcuate rib thereabout, the other pair of said members each including a hollow L shaped part, one extension of each of said parts adapted loosely to pivot in said sockets respectively, and stiffening bars fitted within the other extension of said parts, one of saidlast mentioned extensions adapted to ride upon said rib, one of the members of one cooperating pair being furthermore longer than the corresponding member of the other pair such that the pivot centers are alined at an angle to the perpendicular.

MAX WEBER.
