This invention concerns an improvement in hinges.`

In the use of doors and other swinging objects' where hinges Vhave been employed hitherto, it is `usually necessary to employ door checlrsnof vone kind or another when the motion oft-he swinging element is to be controlled, especially the closing` movement Iota door which would otherwise slam shut under the action of the usual spring hinge.

To thus employ extra appliances adds to the expense ot thevequipment and generally makes an unsightly inartistic arrangement because when one company supplies hinges and another the Idoor checks artistic harmony of design is generally impossible.

It is the object, therefore, of this invention to provide a. simple and eiiicient device `which will serve not'vonly as a hingeV but asfan accurate and regulable door checking means. rhus extra hardware will not -be required. Aand the hinge .members used lcan be designed ot any artistic material to harmonizewith the Aassociated hardware on 'I the dooror other swinging element.

.The invention, stated only 1n general l terms, comprises a hinge member having the usual swing platesadapted to be fastened to a door and a door yamb, or to any two Instead hinge plates by passing through their aligned sleeves,r provide a cylindrical .bar-

rel which acts as the connecting member.

' 'l/vithin the barrelis contained a fluid which acts as a checking or dam eninO medium.

Means within the barrel-.and associated with f lone or both 'oit' thehinge `plates is set into operatic-n by the relative motion of the plates Y to compress the iiuid, and-means related to v.and controlled by-the other .plate and the relative plate positions regulates the degree .of compression and"consequently the dea valve means within the barrel to control the lfluid escape from compression, the 'po'- 192s. semi No. 283.614.

ifi-.i prererred arrangen'ient is to provide a door with two hinges as usual, one ot them, 'for instance, the upper, being a spring hinge upper sleeve 22 andthe lower sleeve 28'are each ,provided with at least three notches, such as 26, into one of winch tongues 27 and Loch nut 1 29r has a bore to receive a squared portion 31 of stem 32 on spring nut 83. The upper end of stem 32 is threaded toreceive cap knob 34. The spring nut 8 is threaded into the upper end of barrel 85 loosely disposed within hinge sleeves 22 and 23, and has an aperture to receive one end ot a spring 36 coiled within the'barrel 35. The other end of spring 36l is received in asimilar aperture in spring nut loosely disposed in the bottom ofbarrel Thisnut has a stein, the outer portion 87 of which is th eaded to receive a cap knob 88 and an intermediate portion'89 is square to lie in a bore in lock nut 30. The tension Vof the spring can be'adjusted as desired by turning the loclrnuts 29 and 30 and then dis-` posing their tongues 27 and 28 in the desired notches 26 in sleevesA 22 and 23. To all appearances this loolrs like an ordinary hinge and can be given any architectural metal in isli'to match adjoiningharclware. l

Y The door and-j amb 24 25 are also provided, pretera-bly ait a lower point, with a hinge-lile door check as shown in Fig. 3 et ses. This comprises, as above, the hinge vplates 2() and 21, with sleeves 22 and 28; also lock nuts 29 Aand-3() with their .tongues 27" and 28-adjustable in one of the notches 26 in vsaid sleeves. `The lock nut 29 in this form however, has a bore to receive a'. squared portion 40 of a spindle 41. The upper end of Y spindle 41 is threaded to receive Cap knob 84 as'before. The spindle 41 extends down through barrelA 35 and isA enlarged at its loweryend 42 to lie in a recess in the lower closed Aend 43 of barrel 85. This barrel'here has. ahead 44to .engage nutjO and a stem V3'? threaded to receive cap lnob 38, with aA 'YPacliing squared portion 37a engaging nut 36.

Beneath nut 29 packing bushing 45 screwed into lthe upper-.end oit barrel 85.

45 and groove in the wall of barrel 85, which prevents y the bushing 48 from turning. This groove extends all the way tothe bottom of barrel V35. The bushing is suppo-rted byrresting on enlarged portion 50 of the spindle 41 lying in a. central bottom opening bore 51'in thev bushing 48. The upper end of the bushing 48 is recessed to Vreceive avalve spring 52 (see Fig. 6), one end yof whichris fastened to the bushing and the other end tothe upper end 53 ot a valve stein54 which extends down along one edge of barrel 35 and seats in a notch therein at its lowerend. The outer edge of this valve stem 54 lies in a groove in wall of barrel corresponding to the groove in which tongue 49 of bushing 48 lies as above described. VIt is evident that the bushing 48 and spring 52 and valve stern 54 can -be moved 180o if desired, since the above-mentioned grooves lie o-pposite eachother. As will be apparent hereafter, this permits the parts to be adjusted Afor a-Kright or left hand door check. i

The valve stem 54 has a valve plate or wing thereon, extending vsubstantially from be-` neath the bushing 48 to the' bottom of barrel This valve plate has an outer bevel edge o. lThus the valve plate 55 is in effect a partition fastened to the barrel 85, only` inot being a fixed" partition or abutment, as is usually the case, it is pivoted for move.- in'fnt in either direction from a neutral posi-` tion, and itsmovement is controlled bothby. cani action and by the force of the contained fluid within the barrel 35. The spindle is provided with a laterallyA extending wing piston 57 Yformed* Vintegral therewith, or otherwise fastened thereto as desired. Fastened to the spindle 41 vnear its middle is a cam plate 58 which, as the spindle turns, is

adapted, under certain conditions, to act on valve piate 55', as will be later described.

die 41 by ineansof a set screw 59. The upper halt or" the spindle 41 is'provided with a bore 60V in which a stem 61 of a needle valve 62 lies. This needle valve 62 controls the flow of iinid through a transverse passage 63 extending through the spindle 41r to oppo-y site sides ofl the wing piston 57. The upper end of the spindle bore is threaded to receive Y threaded portion 64 ofneedle valve stem 61.

A head 65 on the endroi;l stein v61 beneath cap knob 84 'perinitsadjustment of needle" valve te control'the iiuid flow. Elaniinnig'l? ig. 8 it 1s observed that. the

Adoor is halt open but moving to close.V The wing piston 57 ismoving counter yclockwise andiorcing the Afluid ahead of it.'v The valve plate 5in this movement of the hinge is held by'spring 52 against the cam 58.` Therefore an openingvr is "formed betweenthe edge ot valve plate 'and the spindle 41, which howand the door motion is very slow, depending on the opening of the needle valve 62.

Examining Fig. 11, it will be seen that the door isabout to open. The wing piston 57 moves clockwise and the valve plate 55, `for this movement, is moved into the position shown, not only` by the action of the cam 58 but also by the force of the fluid as it is impelled in front of the wing piston 57 and this position is assumed against the action of the spring 52 which tends to hold the valve plate 55 in a normal position. This assumed position permits the opening between the valve plate or movable partition and the wing piston to be as large as possible, whereby practically no fluid resistance is offered to the opening of the door. As soon as the door is wide open, as shown in Fig. 13, and starts back, then the force of the fluid in the opposite direction forces the valve plate 55 against the cam 58 and the closing cycle of operations is repeated,

In the form shown in Fig. 14 and the diagrams of Figs. 15 to 18, the spring hinge and rdoor check are containedA in one hingecasing.

f In this form the hinge plates 66 and 67 have sleeves 68 and 69 embracing the barrel 70. These sleeves, as before, have notches to receive tongues 71 and 72 on lock sleeves or nuts 73 and 7 4. Nut 73 is fastened to barrel 70 by set-screw 7 5. A cap knob 76 is threaded on to barrel 70. The spindle 77 at its lower end is 'a support for a valve cam plug 78 held on by lock nuts 79 and 80. The upper end of this plug carries a cam 81 movable with spindle 77 to vary the position in barrel 70 of valve plate 82 carried by valve 'stem 83 supported between 'the bottom of the barrel and bottom Vspring end plug 84. This valve stem 83 lies 1n a groove 83a in wall'ofjbarrel l70, as'seen in Figs. 14-18 inclusive. Spindle 77 is provided along its lower end with a piston wing 85. Plug 84 is supported on enlargement 86 on spindle 77, and receives the lower end of spring 87, the upper end of which is seated in plug 88 having a slotted upper end 89 to receive a key 90. This key also lies in a slot in lock nut 74. The spindle 77 is pinned to this key. A nut or plug 91 is screwed into the upper end of barrel 70. The upper stem of spindle 77 is threaded to receive cap knob 92l held thereon by set screw 93.

In Fig. 15 the door is closed and the valve plate 8,2 lies close to spindle 77. As the door swings open the cam 81 engages the lower end 94 of the valve plate 82 and gradually direction.

moves it away from the spindle 77. Int-he full open position shown in Fig. 16,the fluid in the barrel has free flow and is not re-V stricted. In Fig. 17 the door is'not quite open 'p and the valve is partly closed. In Fig. 18`

the door is commencing to close and the cam 81 is permitting the valve plate 82 to lie closer to the spindle 77. This is augmented by the pressure of the fluid against, the valve plate 82 as it flows in the direction ofthe arrows in Fig. 18. Y Y

In Fig. 19 I show a diagramwherein doui ble-swing door 95 is hingedly supported above and belowrby double hinges 96, 97, and 98, 99.

Hinge 96 is a spring hinge and 97 is a door 1 check forone direction of swing. Hinge 98 is a spring hinge and 99 is a door check for the opposite direction of swing.

lVhile the operation of the device will probably be apparent from the above detailed dei' cription, it should be noted'that as one hinge plate is moved' relative to the other, the piston i will tend to force the uid in front of it and at the same time the cam associated withfth'e n piston will engage the wing valve to vary/its position with respect to thespindle, so that the opening therebetween will change and the flow of the fluid correspondingly altered. By adjusting the relative position of 'the cam on the spindle'with regardto the relative position of the plates at any instant, the progressive checking of the door can be varied at will. The provision of a manually set njeedle valve in the spindle controlling a passag`e therethrough to opposite sides of the piston will insure that the flow of fluid .will not vbe completely shut off and the door arrested before it is closed, although of course if-it should be desired to stop the door before ity is completely closed, it is merely necessaryv to close' the needle valve entirely. This provides one Vway of maintaining the'door open without using any auxiliary door stops.

It is also apparent that by moving the i and door check, and when associated. as shown in Fig. 19, with spring hinges, is adapted for elficient use in connection with double swing y doors.
