Tall whom t may concern.'
Be it'known that I, CALVIN Kiiiirna citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and use-l the size and lessen the cost cfa combined spring actuated hinge and door check.
A further purposeof the invention is to provide-simple, compact means whereby a door may be easily and quickly placed in position or removed therefromV without the use of tools, thedoor being set at any desired position with relation toits frame.
The invention further contemplates actuating and supporting means whereby when the door is removed to any of its various positions, except at ninety degrees to its predetermined closed position, it will be automatically returned to its closed position. The actuating and checking mechanisms are provided with suitable means to permit of their adjustment without removing the door from its operative position, and all ofthe parts are protected from dirt, dust and weather. `The weight of the door is borne by a part of the hinge engaging floor plate, or by the resilient member supported abo-ve said part of the hinge, while oil or Y other suitable liquid is used in the casing both as a liquid check and as a lubricant.

Fig. 13 is a detail kview of lthe binding nut which coperates with tatable valve of Fig. 10, and-Fig. 15 Vis an enlarged detail view of the lower cam block.
In the embodiment of the invention illustrated in the accompanying drawings, there is shown a floor plate 1 which may be provided with a tapered rectangular opening-2 such as shown in Fig. 9, or may be provided with a depending tapered lug engaging member 3, such as is illustrated in Figs. 1 and 8. This ioor plate is adapted to'be secured to the stationary base or ioor in any suitable manner.
A casing for the spring actuated mechanism is secured to and partially concealed within the door, in which the door `plate 4 is shown connected with a tubular casing 5.
VThis casing is shown providedwith a longitudinal lug 6 within which vmay -be placed a plurality of adjustingmembers to'be here` inafter referred to.
Within the casingis vprovided a plurality of cam blocks 7, 8,` each provided with a spiral engaging surface 9 and a flattened apex 10, so that the engaging 'ends of these oppositely positioned cam blocks 7, 8 appear as bifurcated members, as will be understood from an inspection of Fig. 15. vWhen the cam blocks are at their rest position, as shown in Fig. 1, the flattened apeX 10 of one block, is adapted to rest in the slot 11 of the other member. The lower cam block 8 is provided with a shoulder 12 adapted to engage the lower plate, such as 4 of the tubu- Yso ythe'packing at the base of thecasing. Fig. 1 14 is a detail perspective view of the rowell centrally disposed, indicated at 22,v
the door plate 4 and the lower surface ofV the door, as will be understood from Fig. 1, and to be engaged by a supporting clamp 14.
The clamp 14 is shown more clearly in Figs. 4, 5 and 6, wherein the supporting member 14 is provided with a central'aperture 15 and a plurality of oppositely positioned arms 16 adapted to be moved by an adjusting member or screw 17, to cause the member 14 to frictionally engage the post 13 and thereby Aprevent movement 0f the post.
The lower face of this supporting clamp is shown provided with the tapered depending -lug 18.7.which is adapted to fit within the rectangular opening 2 of the floor plate 1, or the depending angular retaining member 3 of the `floor plate illustrated in Figs. 1 and 8. rlfhe cam block 8 maybe provided with a piston .ring 19, if desired, and a suitable packing 20 may be employed around the post 13, which packing is retained in position by abinding nut 21. As shown in Fig. 9,the member 8 may be provided also with a which is 'adapted to receive the sediment which may be deposited within the casing from the liquid rchecking and lubricating casing.
*the device. Y
substance which is adapted to be usedY with The upper cam block 7 is provided with an elongated stem shown bifurcated'to `providethe arms 23 which are adapted to `be held together by an adjusting screw 24, this cam block being prevented from rotative movement by means of a key 25 positioned in a slot Yformed between the members 23. The key 25 is secured to the easing in any suitable manner, andV permitsof reciprocating movement of the block 7 within` said At the bifurcated end of the cam blockr7 there may be positioned a suitable resilient element such asa helical spring 26, to exert energy against the cam block and force it to the positionshown in Fig. 1. The
'upper end of the casing is internally threaded for a considerable distance, and adapted to be closed by a plug 27which serves also as means to increase the tension Vofthe resilient element 26. lIt is desired torhavevthe cam blocks 7 and 8,fit`the casing' comparatively snugly, the upper block 7 acting as a piston to'act upon a liquid check to bel containedV in the casing. The liquid, such as lubricating oil, may be lpoured into the casing, after the parts shallhave been assem? bled by removing a feed screw 28 which is shown positioned within the tension inclosing end 27. f
The cam block 7 may be provided with the central opening 29 (Fig. 9), which opening is ofsuilicient diameter to permit the liquid checking substance to pass from the reservoir portion 30 of the casing, through the cam' block 7, to the-space 31 which will be formed between the meeting faces of the cam blocks 7 and 8 when moved to the position illustrated in Figs. 9 and 11, filling such space. On the outer surface of the cam block 7 there may be provided an elongated channel 32 toy permit the liquid checking substance to be forced from the space 31 through said channel, back to the reservoir 30 when the coacting cam blocks 7 and 8 are returned to the position illustrated in Fig. 1. It will be understood that the liquid substance will be prevented from returning through the passage 29 by a suitable valve, such as a bail valve 33.
In Fig. 11 the passage 29 is shown of different diameters to accommodate the bail 33, and-serve as a stop or valve to the 'upward passage of theliquid, the ball being retained in position by a suitable device such as a pin 34.y Y
In another embodiment of the invention illustrated in Figs. 10, 12 and 14, there is shown a substantially rectangular groove 36 in lieu of the Vshaped groove of Fig. 9, and with this groove 36 coperates a rotatable member shown in Figs. 10 and 14 as having a stem 37, a groove engaging end 38 having a iattened tapered point, and a peripheral shoulder 39. rFhis rotatable valve member 37 may be provided with a suitable packing 40, and retained in position by a 'binding nut 41, whereby the liquid checking substance may be prevented from leaking aroundrthe adjusting element. Moreover, this adjusting element 37 maybe turned a quarter turn to permit the full passage of fluid through the channel 36, or a quarter cut off the passage of fluid through said channel, while a slight movementin eitherr of the othery directions will permit of the desired passage of iiuid to control the move ment of thel door. Y Y y The packing 20 at the lower end of the casing is designed to prevent the leakage of the checking lubricant from'the casing past the post 13, this packing being retained wedged against the post by the tapered seat 42 of the binding nut 21 at the lower end of the casing. p
vIt may be found desirable also, to cut away a portion of the retaining key 25, as atf43, to permit the cam block to move to yAie its lowest position with relation tothe cam block 8. After the device has been in operation, the key 25 may not snugly fit the space between the arms 23 of the cam block 7, whereupon, access may be had to the casing through the aperture 44 in the longitudinal lug 6, by removing the plug from said aperture, whereupon the screw 24 may be rotated to draw the arms 23 closer together into contact with the key 25.
ln operation, a door provided with the check may be moved to a position so that the tapered lug of the clamping member 14 will register with the ta )ered o Jenin@ 2 of the e l l e {ioor plate 1, whereupon the door may be moved to its vertical position and locked in such position by any suitable means at the top thereof such as a bolt 46 engaging with the keeper in the door frame. The door will therefore, be pivotally mounted by the clamp 14 and post 13, whereupon the door may be moved to the position in which it ris desired to have it returned afterr having been opened. lThe binding element or screw 17 may now be rotated to'tighten the arm 16 into frictional engagement with the post 13 and prevent movement of the cam block. In this position it will be understood that the casing 5 will rotate around the cam block S, while the peculiar formation of the engaging surfaces 9 of the cam blocks will operate to reciprocate the vupper camblock 7 in the casing, the key 25 preventing rotative movement of the upper 'block 7. On the upward movement of the camblock 7, the resilient elementrQ will be placed under compression, and the liquid substance, such as lubricating oil indicated at 47, will be permitted to pass down through the channel 29, past the valve 33 to the space 31 between the cani blocks 7 and 8. 1f the door is moved to a position substantially ninety degrees from that to which it has been set to return, the cam blocks will. assume the position illustrated in Fig. 9, and hold the doorin its opened position. By moving the door slightly so `that the ends 10 of the cam blocks 7 and 8 are out of the abutting engagement, illustrated in Fig. 11, the spiral engaging faces 9 will ride upon each other under the impulse of the resilient element 26, to return the cam block 7 to the position shown in Fig. 1, in engagement with thecam block 8. As .the liquid checking and lubricating substance has been permitted to vflow into tlie space 31 between said cam blocks, it will be displaced from said Vspace,
through the groove 32 or 36. to be returned to the reservoir 30 in the casing,` this return of the fluid to the reservoir can be controlled by the elements 35 or 37 operating in the grooves 32 or 36, and the adjustment of the elements 35 or 37 in the grooves will regulate the closing movement of the door.
An important feature of this construction l resides in the fact that the door may be quickly returned from its opened. to its closed position by manual effort, without disarranging the checking mechanism, the liquid checking and lubricating substance Flowing normally through the channels 32- 36 after the door shall have been pushed to its closed position. -f
The adjustment of the checking substance, orthe arms 23 of the upper cam block, may be effected without removing the casing 5 from the door, by simply rotating the door on its pivots 13 and 46 until the adjusting means 35-45 are exposed to view.
