Letters Patent No. 91,865, dated June 29, 1869.

IMPROVEMENT IN COMBINED LATCH AND LOCK.

The Schedule referred to in these Letters Patent and making pari: of the same.

Be it known that I, HERMAN G. Para, of the city and county of Peoria, in the Stateof Illinois, have invented a new and useful Gate-Latch and Lock; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, the same letters referring to thc same parts, in. which- Figure l is a perspective View.

Figure 2, the caseJ Figure 3, the coveix Figure 4, latch.

Figure 5, vertical bolt.

Figure 6, hook. l

This is a combination of latch and lock, and is designed for either a right or left-hand fastening.

i A is the case, of atriangular shape, having an opening in the longest side, or edge toward the gate, for the admission of the gate-hook C.

Another opening at the top of the case, is for the passage upward of the arm c, and thumb-piece d, of

. the latch D. v

The latter is a lever, having a hook at the end over the recess a, in the upper surface of the hook C.

The remoter end of the latch is pivoted by projectf ing pins c, in the opposite sides of the case.

Midway between the ends of the latch is an arm, c, projecting throngh'the opening in the upper surface of the case, and terminating in the thumb-piece d.

I The button F, attached to the revolving plate j; prevents the arm c from A rising when it is deemed expedient to keep the latch fastened.

A spring of wire, g, presses on thc upper surface of the latch, and after passing onc'e or twice round the pin e of the latch, is secured to the pin behind the latch. (See pin in iig. 2.)

The `hooli C is fastened to and projects at a right angle from the plane of the gate, and isn of a proportionate size with the latch D, and other parts of the case, as shown in the drawing.

The incline of the hook from the point upward, is about twenty degrees.

At thesummit of thc incline occurs the recess a,

A spring, o, retains the bolt on the angle q, when the gateis locked.

In lig. 5 is seen the bolt E, in profile, and at fr, isa recess, which receives the projecting angle j ust meutioned, when the bolt is upin the recess b of the hook C. I

The operation of this latch and lock is as follows:

On lthe entrance of the hook C into the opening in the side of the lock, the incline. of the hook is forced under the hook of the latch D, and for temporarily fastening the gate, thebutton F may be turned, which prevents the arm .c of the latch D.

The hook is further secured by means of the bolt E, rising vertically into the'slot b of the hook, operated by means of the key and the lugs or dogs a n, on the side of the bolt E.

NVhat- I claim as'my invent-ion, and desire to secure by Letters Patent, is-

The combination and arrangement of the hook C, latch D, bolt E, and revolving button F, substantially in the manner and for the purpose as herein shown and set forth.

. HERMAN G. PEIN.
