THOMAS P. STRAUP AND LOUIS MORGEN STERN OF EASTON, PENNSYLVANIA; SAID MORGENSTERN ASSIGNOR TO SAID STRAUP.
SPECIFICATIQN forming part of Letters Patent No. 294,746, dated March 4, 188,1, Application filed October 13, 1883. (Model.)
To @ZZ whom t may concer-1t:
Be it known that we, THOMAS P. Sra-mr and Louis MoReENsTERN, citizens of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Hinges, of which the following is a specililock the rod Ein position.
cation, reference being had therein to the ao` companying drawings.
Our invention relates to hinges; and it consists in the parts which will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure l represents a face view of our device, a part of the cylindrical casingbein g broken away, showing the spiral spring encircling a rod. Fig. 2 is atop plan view ofthe device. Fig. 3 is a face view with the casing and its flange in section. In this view the engaging teeth on the casing differ somewhat in the structure from the teeth shown in l. Fig. 4 is a perspective view of one of the wings provided with the toothed' cylindrical socket-section. Fig. 5 is 'a perspective view of the disk, its plug, and a fragment of the rod which receives the spiral spring. The parts shown in this figure are inverted, to better illustrate the circular depression on the under side of the disk, and y the small slots therein adapted to receive and secure the upper end of the locking-rod.
Like letters indicate like parts throughout the several views.
A represents one of the wings, provided with screw-openings A.
Bis a cylinder, rigidly united to wing A. Said cylinder is open at both ends.
C is a lip formed at the intersection of the wing A and cylinder B, and O' is a similar lip at the upperl end of said intersection.
O2 O2 are openings in said lips for the reception of the locking-rod'E.
D is a lug formed on the outer lower surface of the cylinder. This lug is adapted to Said rod is provided with two lugs, E', between which the cylinder-lug D lies when the hinge is locked, as shown in Fig. 3, and thus kept from dropping down and unlocking the hinge. By partly revolving the locking-rod E from its .position shown in Fig. 3, and in dotted lines of Fig. 1,
its lugs E' are removed and disengaged from the cylinder-lug D. Then, by lowering the rod E to `the position shown in full lines, Fig.
.1, the upper end of said rod is disengaged from F3 is a socket-plug iixed on the upper side u of the disk F.
F* is a small opening in the cylinder B, adapted to engage and secure the vlower end of the spiral spring, though it may be secured in any other suitable manner.
F5 is a rod xed to the under side of the disk. The spiral spring Gis coiled around this rod. The lower end of said spring is fixed to the cylinder, and its upper end is fixed to the under side of the disk F.
Fi is the threaded end of the rod F5, and G is the bevel-nut thereon.
F7 are clutching-teeth fixed on the upper side of disk F 4at the intersection of the plug F3.
H is one ofthe hinge-wings, having screwopenings H'.
K is a cup or socket-piece formed integral with the wing H. Y
J is a lip integral with the hinge H and cup K. Said lip is provided with an opening, J',
'adapted to engage the upper end of the lock-l ing-rod when it is desired to secure the hinge in afolded position, in which case thelockingrod is passed through one of the disk-slots F2, and thence into the opening J', whereby the wings A H are locked.
Vv'hen the lugs E' D are engaged in the manner shown in Fig. 3, the upper end ofthe lock` ing-rod E only engages the slots F2, and does not pass wholly through the disk; but said rod may, however, by further insertion upward, be placed in the opening J', and thereby secure the wings in a folded position, as
indicated. Then', by turning the locking-rod so thatthe upper of its lugs E' rests upon the lug D, it is secured and prevented from falling down and unlocking the hinge.
Our hinge is so constructed that paint can- ICO ` and will hold the shutter wide open.
not get into any of the working parts and there hardening hold them fast or prcventthe free working ofthe several parts. The hinge can be used for shutters or for doors. In the latter case the hinge must be reversed, as it is the purpose, generally, to hold doors shut and shutters open.
The hinge is easily taken apart and the tension readily adjusted without removing the shutter. f his is done by putting upper or shutter part on with shutter wide open, so that the teeth engage; then by closing the shutter and pushing the locking-rod up into one of the slots, F2, in the rim; then by disengaging the teeth, by lifting the shutter alittle, then opening wide, then engaging the teethand letting the pin drop out of slot, so that the tension is then on, If more tension is desired, it is only necessary to repeat the operation. By reversing the process the tension may be lessened or entirely taken off.
The opening J on shutter part of hinge is to engage the locking-rod and hold the shutter partly closed or L"bowedi The slots F2 are made wider at top than at the bottoni, to facilitate casting.
XVe prefer the form of teeth shown in Figs.
l and 4, for the reasons hereinafter given; but as this forni involves practical diiiiculties in manufacturing the hinges, we regard the form shown in Fig. 3 as almost as good and amply secure. rlhe tension of the spring causes sufiicient friction between the teeth to prevent the shutter from being lifted ofithe hinges by wind or other accidental causes, 'and it is just' that much more secure in this respect than the hinges usually used on shutters known as loose butts.77
The teeth. when made as in Fig. 1, lock, and thus it is impossible to lift shutter vcrtically oft` the hinges, which is a great advantage in sudden gusts of wind.
Our hinge being provided with means for holding t-he shutter in any desired position, it is,therefore, notnecessary to employ catches holdbacks, or other devices to hold the shutters back or open.
Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a hinge, a cylinder having open ends, said cylinder being provided with a wing, and a disk provided on its upper side with a socketplug and clutching-teeth, in combination with a socket-clutching cup and a wing formed integral therewith, a rod fixed to the underside of said disk, and a spring having one end secured to the disk and the other end secured to the cylinder, substantially as described, and for the purpose set forth.
2. In a hinge, a cylinder having a wing projecting therefrom, said cylinder being provided with guide-lips and a locking-lug on the cylinder, a locking-rod provided with lugs adapted torengagethe said locking-lug, as specified, a disk providedwith slots around its outer edge, and having on its upper side a socket-plug andclutching-teeth, and arod on its under side provided with a spiral spring wound thereon, the lower end of the spring being connected to thecylinder Land the upper end thereof xed to the disk, in combination with a wing and a socket-clutching cup, substantially as described, andL for the purpose set forth.
3. In a hinge, a cylinder having a wing connected thereto, said cylinder having lug e D and lips C O, provided with openings at the intersection of said wing and cylinder, a locking-rod, E, provided with lugs E,-a disk` provided with a recess for the reception of the upper endof the cylinder, said disk having slots around its outer edge, and provided on its upper side with a socket-plug, F, and clutching-teetl1,and arodon its under side provided with a spiral spring wound thereon, the upper end of the spring being fixed to the disk and t-he lowerk endrthereof secured to the cylinder, in combination with a wing and a socket-clutching cup formed integra-l, substantially described, `and forthe purposes set i'orth.
4. In a hinge, a cylinder having a wing Vfixed thereto, said cylinder havingv lng D` and lips C C', provided with openings at the intersectionof said wing and cylinder, a locking-rod, E, provided with lugs E', a disk provided with a recess for the reception ot' the upper end of the cylinder, said disk having slots around its outer edge, and provided on its upper side with a socket-plug, F3, and clutching-teeth, and a rod on its under side provided with a spiral spring wound thereon, the upper end of the spring being fixed to the disk and the lower end thereof secured to the cylinder, in combination with a wing and a socket-clutching cup and a lip, J, having opening J at the intersection of said cup and wing, substantially as described, and for the purposes set forth.
In testimony whereof we aiiix our signatures in presence of two witnesses.
