Application filed June 25, 1313. Serial No. 775,828.
To all whom it may concern I Be it known that I, STEPHEN A. SLAUSON, a citizen of the United'States,resid ng at Cedar Rapids, 1n the county of Linn and State of Iowa, have invented certain new 7 and useful Improvements in Gate-Latches,
of which the followlng 1s a specification, reference being had therein to the accom-v panying drawing.
This invention relates to improvements in gate latchesand in particular to a latch for engagingtheswinging post of a folding swing gate. i
' The latch may be swung open in either direction and when pushed into closed position automatically engages the lat-ch which, looks it in closed position. Latches of this general but I havedevised mine in such a way that there is no possibil- 3 ity, of the latch failing to engage whenthe awaythat when the free endof the gate gate is in elosed' posit1on and permit the gate to swmg by.
'A further advantage is the position ng of he engaging forks on the latch in such is swung or folded to a position in which the latch end of the gate 1s the same dis-- t ance from the ground, its operation is not interfered with. v My improved latch is simple in construction, the post engaging forks being duplicates and the entire latch being rea ily assembled and mounted in position.
In the drawings, Figure l shows a side elevation of my improved latch as mounted on afence postand engaging the tubular gate post. Fig. 2 is a view'simila'r to Fig. 1 showing the latchend of the gate elevated or'folded to a position above the ground. Fig; 3 is a front view of my improved latch, parts of the center being broken away. Fig. 4; is a plan view of the latch when in normal locked. position. Fig. 5 is a view similar to Fig. a showing a latch swung to permit the opening of, the gate; Fig. 6 is a plan view f e f t ga e e g ging r detac from the latch I hanism. Fig. 7 is a side elevation ofthe fork shown in Fig. 6." Fig.
8 is a vertical fragmentary sectional view is constructed sothat the gate stated, the opening 'in back to a horizontal plane,
' order to raise thela'tch end above the ground as is oftentlmes desirable in order to permitsmall livestock to pass through the gate Without permitting the passage of larger animals. A coil spring 1, one end of which is connected tothe upper corner of the gate adjacent the pivotal endconnected to a wire lower diagonally opposite, corner of the gate. Th's causes the front or latchend of the gate to normally have a tendency to raise, and in order to control this'movement and permit the elevation of the front only when desired, a tension or lock wire 3' extends midway of the lower portion of the'gate upward to the corner of the gate opposite to that to'which the swing end i'sconneeted and there engages a series ofnotches The gate'engaging members of the latch comprisetwo forked'pieees ,5 provided with upward extending collars; 6. A rectangle opening 7 is formed in eachpf the collars 6 te ing dow hro gh t ffork anda ug v s fo d on it upp nt d A vertical fiat bar 8 is slid through the opening 7 on two' of the forks and fits loosely therein so asto permit longitudinal movement of the bar within the forks. Secured ameter somewhat greater than that of the collars 6. These, shoulders 10 provide pivotal supports for theforks 5. As previously the shoulder 10 is of a diameter somewhat greater than that of the collars 6, and as theshoulder 10 is of comparatively thin metal, the collar 6 with its lug 11 can, by tipping the fork 5, be in serted through the opening and when swung the lug 11 will extend over the edge of the shoulder 10 and hold the fork in position. The forks are in this manner pivotally mounted in the brackets.
A latch member 12 is secured by the rivet l3 to'theupp'er end of the rod 8 and is r0 vided witha rearward projection l4 w ich normally rests in the opening formed between the two vertical walls 15 extending upward from the bracket 9. Handles 16 extend outward from the latch member 12 at each side at the post. A Spring 17 is post D, has its other 2 extending to theing bracket, a fork having a positioned over the lower end of the rod 8 and its upper end held tightly against the lower fork 5 by means of a cotter pin 18 and washer 19 carried at the lower end of the ro v ,The spring 17- normally holds the rod 8 down and secures the latch member '14 between the Walls'15 of the upper bracket 9. In order to open the gate one of the handles 16 is grasped and moved upward carrying with it the'rod 8 and the latch member 12. When the-latch member is raised to a po sition so that the extension 14, is above the tops of the walls 15, the rod, latch member, handles, and all may be swung in either direction carrying with them the gate engaging forks 5 thus permitting the gate-to be swung open. The latch is then left in this position. When the gate is swung closed, the post engages with the two forks 5, swinging them into the normal central'position whereupon thev spring 17 draws the rod 8 down, carrying-the extension 14 into the socket between thebracket walls 15. The gateis thus locked in its closed position and it 'is impossible for the gate'to swing by and ,openon the other side-as is frequently the case with forms of latches now in use. The forks are spaced a considerable distance apart on the rod 8 so as to permit the gate to be lifted, as in Fig. 2, and stillp'ermit the engagement of jthe forks "withthe post. This is of a particula-radvantage in foldingv gates of the'type illustrated... i
I do not hereincla'im' any of the novel features of structure .which. characterize the gate, the claims herein being limited to matters incident to the latch; having filed another application SerialNo. 775,827, on June 25,-"1913, wherein are presented claims pertaining to the gate.
What-I claim is i 1; A gate-fastener comprising a supportpivoted for swinging post 'of a gate, a rod ortion of non-circular cross sectionslida le through an a erature in the said fork, a latch carried y the rod and connection with the cally 2. In a gate fastener comprising a fork i pivoted for swinging connection with the post of a .gate, a bracket in which the said fork is pivotally mounted, a rod having a portion of non-circular cross section vertislidable through an aperture in the fork, a latch member :mounted on the upper end of the rod and adapted to rest normally within a notch formed'in the bracket. and a spring engaging the rod to normally hold it in the position with the latch in the notch.
'33. A gate fastener comprising a fork pivoted for swinging connection with the post of a gate, abracket within which said fork is pivoted, a rod having a portion of non circular cross section keyed to the fork but vertically slidable in a corresponding noncircular aperture therein, a latch member secured on the up er end of the rod and adapted to normally rest within a notch formed ,in the bracket, a spring positioned on the rod to normally hold it in the position with the latch in the notch, and latch operating handles diverging from each side of the said latclrmember.
4. A gate fastener comprising two forks pivoted for swinging connection with the post of agate and spaced vertically one from theother, brackets within which each of the forks are pivotally mounted. a rod having a portion of non-circular cross-section verti ca 1y slidable through apertures in the said forks and brackets, a latch member secured on the said rod and normally resting within a notch formed in. one of the brackets, and a spring positioned on the rod to normally hold it in the positionwith the latch in the notch. i
In testimony whereof I aflix my signature, in presence of two witnesses.
