DOOR-SPRING.

srncrrrcnrron forming part of Letters Patent No. 622,567, dated April 4, 1899.

Application-filed September 8, 1898- Serial No. 690,523. (No model.)

To all whom it may concern.-

Be it known that I, WARREN M. THOMAS, a citizen of the United States, residing at North English, in the county of Iowa and State of Iowa, have invented a new and useful Spring for Gates and the Like, of which the following is a specification.

This invention relates to springs for gates, doors, shutters, and the like; and the object thereof is to provide a spring composed of two members and a link connecting the members, whereby each spring is greatly relieved of strain, thereby giving longer life thereto.

Further objects and advantages of a gatespring constructed in accordance with the present invention will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a gate having my invention applied thereto. Fig. 2 is a sectional plan view of the gate in open position. Fig. 3 is adetail perspective view of the spring.

Like numerals of reference designate corresponding parts in all the figures of the draws Referring to the accompanying drawings, 1 designates any common or ordinary gate hinged to the usual gate-post 2.

Any form of latch may be used to lock the gate, but I prefer to use that shown in the tially the same form.

drawings, comprising the end picket 3, pivoted 'to the lower rail, the upper end thereof working through a slot 4- in the upper rail. A spring 5 is secured to the next picket and bears against the latch to force it outward to engage a suitable stop 6 upon the other gatepost 7.

r The spring for closing the gate is composed of two spring members 8 and 9 of substan- They are each formed from a single length of spring-wire twisted intermediate its ends and near one end into a spring-coil 10. The short end 11 of the wire forms a means of attachment, while the other end extends in approximately the opposite direction, forming a long spring-arm 12, which of, by means of the short attaching end 11, and the other is attached to the hinge gatepost on the opposite side of the gate and in the same horizontal plane, with the long arms extending toward each other. A link 14 connects the ends of the arms 12 by means of the eyes 13. This link, it will be observed, passes between two of the pickets and causes a strain upon each of the spring members as the gate is opened.

Fig. 1 shows the gate in closed position, with the spring in its normal position and exerting no strain. In this position the spring-arm 12 of the gate member extends outward from the gate and the post member is appronimately parallel therewith; but when thrown open, as indicated in Fig. 2, the link 14 holds the ends of the springs in the same normal position, which draws the gate member along side the gate and the post member across in front of the post, which brings a tension upon the members with a tendency to close the gate.

I have shown and described my invention as applied to a gate, but it is obvious that it may be applied to a door, shutter, or other hinged object.

The spring is preferably attached to about the center of the gate, which disposes the same so as to act evenly upon the gate and not twist it to any degree.

Changes in the form, proportion, and minor details may be made without departing from the spirit and scope or sacrificing any of the advantges of the invention, and therefore I do not wish to be understood as limiting myself to the precise construction and arrangement as herein set forth.

Having thus described the invention, what is claimed isv 1. A spring for gates and the like, compris-= ing two spring members having their opposite ends rigidly connected, respectively, to the gate and to the hinge gate-post, and a link connecting the adjacent ends of the springs and extending transversely therebe= tween, substantially as shown and described.

2. A spring for gates and the like comprising two spring members, one being attached to the gate and the other to the gate-post and on the opposite side of the gate, and a link connecting the spring members and extend 7 ing through the gate from front to rear, substantially as shown and described.

3. A spring for gates and the like comprising two duplicate spring members, each being formed from a single length of spring-wire twisted intermediate its ends into a springcoil and adapted to be attached respectively to the gate and to the gate-post, upon opposite sides of the gate, and a link connecting the spring members and extending through the gate from front to rear, substantially as described.

4. A spring for gates and the like comprising two duplicate spring members, each being formed from a single length of spring-wire twisted intermediate its ends into a spring- WARRENM. THOMAS.
