SPECIFICATION forming part of Ltterslatent 'No. 734,447, dated July 21, 1903. Application filed Novemberlfl. -1902.- Serial lilo-131,823. (Remodel) To all whom it may concern:

Be it known that I, HARRY J .VALENTINE, a citizen of the United States of America, anda resident of Cleveland, Ouyahoga county, in the State of Ohio, have-invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification.

This invention relates tospring-hinges of the class, whether single or double, which are applied to the door and door-frame unset, but which are so constructed that after screwing them in position their springs may be tightened up and placed under tension. Y

The objects of the present invention. are, first, to so construct thetubularpintle'on which the hinge-knuckles turn that the opcrating-spring may be readily and conveniently set from an intermediate point on the hinge; second, to provide ample and smooth antifriction-bearings for the knuckles, and,"

,third, to provide the hinge with a checking hinge which will be efflcient in action and which overcomes some of the defects of those now on the market.

My invention consists of certain features of construction and combinations of parts, to be hereinafter described in detail and then pointed out in the claims.-

In the accompanying drawings, Figurel' is a side elevation ofa hinge made in accord ance with the present invention, the leaves being shown closed. Fig.'2 is a plan view with the leaves closed and the upper tip 'or knob and its rivet removed. Fig. 3 is a detail of the npperpart of the hinge, partly broken away to disclose the parts inside the tip and tubular pintle. Fig. 4 is a transverse section through the base of the tip and intorior parts with the leaves in plan and opened out fully. Fig. 5 is a longitudi-nal section of the central portions of'the-hinge, the leaves Fig. 6 is a detail perspective view of the cup or disk to which the upper end of the operatingspring is applied. Fig. 7 is a detailperspective view of the cup or disk to which the upper end of the check-spring is applied. Fig.

.8 is'a detail'perspective View of the upper sec tionof the tubular pintle, and Fig. 9 is a detail perspective view of one of the-Washers between the knuckles.

While in the drawings the invention is ,shownas applied to a single hinge, it is to be understood that the invention is equally applicable to a double hinge.

The'hinge-leaves AB are provided with knuckles ab, respectively, through which the tubular pintle composed of sections 0 0' passes. Preferably the lower section 0 is provided with a capstan-ring D, slipped over it and secured on it by a set-screw d and located between the'two middle knuckles of the hinge shown, which knuckles hear at their adjacent edges upon the said ring. ring has a suitable number of holes 01 for receivinga locking-pin 61 which is inserted in position in one of them and is engaged by the leaf B in opening the hinge for straining the main or operating spring to be described. The upper section 0 of the tubular pintle is secured to upper knuckle a of leaf A by a set screw or screws 0, and the lower section 0 is free to be adjusted in the lower knuckles. Set-screw 0 screws also into the flange of a cup or flanged disk E, which is located in the upper end of tubular section 0. An axial opening e, for the purpose to be stated later, is formed in the cup E, and a holee is located in the disk at one sidethereof to receive the This 'upwardlybent upper endf of the helical main or operating spring F, the diameter of which is nearly that of the inside of the tubular pintle. A downturned lower end f on the spring F is engaged in a side hole g, lo- .cated in an inverted cup or flanged disk G, secured in the lower end of the tubular section 0 by set screw or screws 0. The spring F simply engages in the holes '6 g at: both ends and requires no other fastening; To tighten the spring, a short lever or nail i'sinserted into one of; the holes in the capstanring D and the locking-pin (1 set behind leaf B, the lever being reinserted, the ring being turned, and the locking-pin reset until a sufficient tension is placed on the spring. The method of doing this is well known.

The lower knob or tip H is secured to the pintle-section C by the described set-screw c, and the upper knob II is placed onto the upper end of the upper pintle-section C, it being secured in position in the manner to be described later.

Between the knuckles a b of the hingeleaves are suitable bearings formed by preferably dished collars or washers I I, which are only slightly larger in internal diameter than the tubular pintle and which are arranged in pairs, placed with their concaved faces together, preferably to form raceways for antifriction-balls j. These collars I I are provided with outturned key-lugs or projections 1;, which interlock with corresponding recesses 71 in the knuckles, so that one of the collars of one pair between adjacent knuckles is locked or anchored to one knuckle and the other collar is fixed to the other knuckle. The outer contact edges I of the collars preferably bear upon each other and take up more or less wear. In this event they are made of case-hardened steel to serve as wearcollars, the use of the autifrictiomballs then being a matter of choice only. The balls bear on the outer surface of the tubular pintle, so that rolling antifriction-stnfaces are not only provided between the knuckles, but also between the knuckles and pintle.

The invention further resides in means for checking or retarding the action of the operating-spring just before the door closes, thereby preventing slamming of the door. To this end a helical check-spring K is preferably located in the pintle within and inclosed by the operating-spring F, and as it is somewhat less in diameter and the springs are suitably fixed apart the springs do not interfere by rubbing on each other. The lower end of the checkspring K is bent downwardly at k and is engaged in a hole g in the lower cup or disk Gr, while the upper coils of the check-spring pass through the enlarged central opening e in cup or disk E. The upwardly-bent upper end of the check-spring is engaged in a hole Z in an inverted cup or flanged disk L, which is located in the upper end of the pintle-section C and may turn therein. The rim of the cup or flange of disk L is presented downwardly to abut against and turn on the upwardlypresented rim of the cup or flange of the disk E. A series of holes Z is formed in the flange of cup or disk L, and opposite these holes the pintle-section O has a short transverse slot 8, which is also located opposite a series of holes m in the rim of the upper knob H, the said holes Z registering with the holes m, so that a check or tension pin on may be inserted in the same. This pin m puts tension on the check-spring reverse to the tension of the operating-spring, to which end it is adapted to be impinged on by the inner side of the leaf B. The tension on the check-spring is obtained upon tightening the same up by insorting a lever or nail in the holes Z m and turning the knob H and cup or disk L until a light tension is imparted to the said spring,

when the check-pinm is inserted in other of said holes and abuts against that end of the slot m adjacent the leaf B when the leaves A B are opened. The initial tension is such that when the leaves are fully opened the pin m will be brought, preferably, to position shown in Fig. 4:, and when the leaf B closes toward and abuts on said pin the latter acts as a check to the quick action of the operating-spring and prevents slamming of the door, acting contrariwise to the operating-spring.

For holding the knob H and the cup or disk L in place against accidental separation from the hinge the same are preferably connected by a pin or rivet 1', which passes through a transverse slots at that side of pintle-section O which is opposite the slots. The pin or rivet 1* preferably forms a stop to limit the tension placed on the check-spring.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In aspring-hinge, the combination of the leaves and knuckles, a tubular pintle inserted through the knuckles, and composed of sections, one of which is attached to one leaf and the other of which is rotatable relatively thereto, a capstan-ring secured on the rotary section and located approximately midway of the hinge, the division between the two sections being located to one side of the said ring, and means for setting the rotary section in adjusted position against one of the leaves, and an operating-spring in and attached to said rotary section to close the leaves, substantially as described.

2. In a spring-hinge, the combination of the leaves and knuckles, a-tubnlar pintle inserted through the knuckles, and an operatingspring and paired collars arranged between adjacent knuckles of the respective leaves for taking up wear by the contact of their faces with each other, one collar of each pair being secured to one adjacent knuckle and the other of the pair being secured to the other adjacent knuckle, substantially as set forth.

3. In a spring-hinge, the combination of the leaves and recessed knuckles, a tubular pintle inserted through the knuckles, an operating-sprin g, and collars between the knuckles, one provided with a lug inserted in the re cess of one adjacent knuckle and the other with a lug inserted in the recess of the other adjacent knuckle, substantially as set forth.

4. Inaspring-hinge, the combination of the leaves, an operating or main spring, and a check-sprin g opposing the action of the operating-spring, substantially as set forth.

5. In a spring-hinge, the combination of the leaves, an operating-spring, and a checkspring of less diameter than'and located within the operating-spring, said check-spring serving to check the closing actionof the operating-spring when the leaves are about to close, substantially as set forth.

6. In aspring-hinge, the combination of the leaves, the operating-spring, a check-spring inclosed within the operating-spring, one end of each spring being fast at one end of the hinge and the other end of each spring being adapted for being tightened, means for tightening up the operating-spring, and means for tightening up'the check spring, said check- -spring acting against the operating-spring pintle at each end, said pintle being sectioned between the disks, and an operating-spring attached at one end to one disk and at the other end to the other disk, a check-spring secured to the fixing-disk of the operatingspring at one end, the other end of the checkspring passing through an openingtin the other disk, and means for tightening up or adj usting, the tension of the check-spring, substantially as set forth.

9. In a spring-hinge, the combination of the leaves,the operating-spring, and a check-pin arranged between the leaves so as -to be out of contact with the leaves when the hinge is opened and to contact with the closing leaf when the same is closing, tocheck the action of the operating-spring, substantially asset forth.

10. In a spring-hinge, the combination of the leaves, the operating'spring, a checkspring, a pin for acting on the spring and against which one of the leaves abuts, and means for limiting the movement of the pin to a portion of the extent of movement of the abutting leaf.
