HENRY P. KOCHSMEIER AND GEORGE M. XVALDORF, OF FREEPORT, ILL.
GPBCIFECATIQN forming part of Letters Patent No. 340,790, dated April 27, 1886,
Application filed March i, 1896. Serial No. 193,744. (Model) To all whom it may concern:
Be it known that we, HENRYP. KooHsMErER and GEORGE M. WALDOR'F, both residents of Freeport, in the county of Stephenson and State of Illinois,have invented certain new and useful Improvements in Spring-Hinges; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which-- Figure 1 is a perspective view of our improved spring-hinge, showing it attached. Fig.2 is an axial sectional view of the same. Fig. 3 is a detail view of the spindle with the springs and buttons; and Fig. 4 is a similar View ofthe spindle, a spring, and one of the buttons.
Similar letters of reference indicate corresponding parts in all the figures.
Our invention has relation to thatclass of springhinges in which the leaves ofthe hinges are provided with projecting lips pivoted together, and in which two springsupon aseparate spindle, placed between the pivoted lips, have their ends secured to the leaves of the hinge; and it consists in theimproved construction and combination of parts of the same, as hereinafter more fully described and claimed.
In theaccompanying drawings, the letters A A indicate the two leaves of the hinges, which are formed with the projecting lips or cars B, which are pivoted together, having pintles O, fitting in perforations D in the opposite ears and turning in the same. The middles of the inner edges of the leaves are formed with perforated ears or bails E, bent slightly outward from the planes of the leaves.
The spindle F is preferably formed with a narrow flange, G, at its middle, and has two transverse notches, H, at its ends, and two small studs, I I, project from the side of the spindle, each stud at a distance from the flange at the middle.
Two sleeves, J J, fit upon the spindle,bearing with their inner ends against the central flange, and each sleeve is formed with a longitudinal groove, K, in its bore, which groove may slide over the stud upon the spindle, which stud will bear against the outer end of the sleeve after the sleeve has been slipped upon the spindle and turned so as to bring the groove away from the stud, the stud thus retaining the sleeve upon the spindle. Each of these sleeves is provided at its inner end with a flange, L,which is formed with an outwardlyprojecting lug having a flatl1ook,M,at its end, which hook projects inward at one end, so as to project over a portion .of the other half of the spindle, and the flange is provided with a notch, N, in its outer face to the rear of the hook.
An annular button, 0, fits upon each end ofthe spindle,and is formed with an outwardlyprojccting flange at its outer end,which flange is lettered P, and this flange has in one side a notch, Q, which extends into the central bore of the annular but-ton.
A spiral spring, R, is placed upon each half of the spindle, fitting with its inner end upon the reduced outer end of the sleeve, and has its 'i nner end fitting in the notch in the flange of the sleeve, while the outer portion of the spring fits upon the inner reduced portion of the button and the outer end of the springflts in the end of the spindle.
, The wide hooks of the sleeves are hooked into thebails or ears at the middles of the inner edges of the hinge-leaves; and it will be seen that when the leaves are swung at an angle the leaves will turnthe sleeves upon the spindle against the springs, which are held at the outer ends by the notches in the spindle, so that the tension of the springs will tend to close the leaves back into "their original position.-
After the leaves in opening have passed over the position in which they stand at right angles to each other, the spindle with the springs will be forced out from a line with the pintles of the hinge-ears, and the tension of the spring drawing upon the bails or ears of the leaves will tend to draw the leaves to stand in a position parallel with eachother, so that after a door has been opened beyond a certain distance it will be drawn open by the springs and held open by the springs.
It will be seen that the sleeves having the Lal hooks will be held firmly in place without any danger of their slipping off of the spindle by means of the studs upon the spindle, and the buttons at the ends of the spindle will be prevented from slipping off from the said ends by the inwardly-bent ends of the springs, which secure them to the spindle by passing into the notches of the spindle, preventing the buttons from coming 0E in any other way than by sliding the entire spring off the spindle.
Having thus described our invention, we claim and desire to secure by Letters Patent of the United States 1. In a spring-hinge, the combination of the spindle provided with a central flange and two studs at equal distances from the central flange, with the hook-bearing sleeves fitting upon the v spindle at both sides of the central flange, bearing with their outer ends against the studs and having longitudinal grooves in their bores for sliding over the said studs, as and for the purpose shown and set forth.
2. In a spring-hinge, the combination of the spindle formed with transverse notches in its ends, the buttons fitting upon the ends of the spindle and having reduced inner ends, and having a notch in the outer faces extending into the central bore, and the springs fitting upon the spindle and having their outer ends bent inward, and fitting in the notches of the buttons and ends of the spindle, as and for the purpose shown and set forth.
3. Ina spring-hinge, the combination of a spindle having a central flange and transverse notches in its, ends, and provided with studs at equal distances from the central flange,l1ookbearing sleeves fitting, upon the spindle and having flanges at their inner ends formed with a notch each in the outer faces and bearing with their outer ends against the studs upon the spindle, and having grooves in their bores for sliding over the studs, buttons having reduced inner portions and fitting upon the ends of the spindle, having each a notch in the outer face extending into the bore, and springs having their inner portions fitting upon the sleeves, with the inner ends resting in the notches of the flanges of the sleeves,and having their outer portions fitting upon the reduced inner portions of the buttons and their outer ends bent inward and placed into the notches of the buttons and ends of the spindle, as and for the purpose shown and set forth.
4. In a spring-hinge, the combination of hinge-leaves having outwardly'proj ecting ears at their inner'ends, pivoted together and provided with perforated ears or bails upon the middles of their inner edges, a spindle, sleeves turning upon the center of the spindle and having wide hooks projecting from them engaging the ears or bails upon the inner edges of the leaves, and springs coiled around the ends of the spindle and secured to the sleeves and to the outer ends of the spindle, as and for the purpose shown and set forth.
5. In a spring-hinge, the combination of two hinge-leaves having obliquely-projecting ears pivoted together by pintles, and having perforated ears or bails at the middles of their inner edges, a spindle having a central flange, and having notches in its ends and studs at equal distances from the flange, sleeves having longitudinal grooves in their bores for sliding over the studs of the spindle, and bearing with their outer ends against the studs, and having flanges at their inner ends provided with notches in the outer faces and hooks for engaging the bails of the leaves, buttons fitting on the ends of the spindle having notches in their outer flanged faces extending into the central bores, and springs fitting upon the sleeves, with their inner portions having their inner ends engaging the notches in the flanges, and having their outer portions fitting upon the reduced portions of the buttons, and having their outer ends inserted through the notches of the buttons and of the ends of the spindle, as and for the purpose shown and set forth.
In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
