IMPROVEMENT IN SNOW-GATE.

@its rlgimli feierten tuin tigre etters rztin mit making part' nf tte sante,

TO, ALL WHOM IT MAY OONCERN:

Be it-kn'own that I, A. B. MURRAY, of Henderson, in the county of Mercer, and State pf Pennsylvania, have invented a' new and improved Sncw-Gateg and I do hereby declare the following to bea full, clear, and Vexact desbription of the same, reference being had to theaccompanying drawings, making part ot" this specilication, in which- Figure 1 is a side elevation o f the gate when closed.

Figure 2 is a representation of a horizontal section en thelinex ce.

Figure 3 is a view ofthe swinging frame B detached,y i

' Figure 4 is an end view of a hatten, showing arrangement of friction-rollers.

The nature of my invention relates to a farm-gate, especially adapted to use in case of snow-fall, being I constructed and supplied with suitable devices, by means of which it may be raised to any Adesired height above vthe snow, and in' such position allowed to swing to either side without obstruction. i

In the accompanying drawings- A represents the main post, to which the gate is attached, andwhicb is embedded in the ground or secured r in a suitable sill or frame. i

B represents a swinging frame, in which the gate slides up .and down.

This frame is composed of a square piece, of suitable dimensions, with ajournal at each end, having their bearings in two brackets, a, secured to the post A by mortisel and key, or in 'any suitable manner: l

The gate is composed of the horizontal railsb and the two vertical end-pieces C C, and is furtherstrengthened by the diagonal brace D. 4 i These end-pieces are secured to the horizontal rails by mortise, as is likewise the additional hatten E@ The swinging frame B has o. long vertical slot, G, as seen in fig. 3Min which the gate slides, being secured l in position by the battens C and E.

H and H are double friction-rollers, the former securedin slots in the top of betten E,and the latter working in similar slotsin the bottom of batten C.

Iis a bar, pivoted to the second rail of the gate, and also to theV lever K, which in turn is pivotd at one end to the bottom of thenswingingA frameB. I Y

y The diagonal brace D has holes m, in which isplaced the pin it for adjusting the height of the gate.

P is a. short stake or post, secured to the sill or placed in the ground a short distance from the end-piece Cf, and has a notch or slot,|p, in which the gate rests when closed, as shown in fig. 1.

It will be seen that, by elevatingthe forward end of the lever K, the gate is raised to any desired height, sliding inthe slot'G, and assisted by the friction-rollers H.H rolling on each side of'said slot, where it may be held'by the pin n, and allowed to swing freely to either side.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The friction-rollers H H', substantially as and for the purpose described. l

2. YThe combination and arrangement of the leverK, bar I, diagonal 4brace D, with holes m and pin n,

substantially as and for the purpose'set forth. 1

3. The construction Yand arrangement of the battons C and E, substantially in the manner and for the purpose'speciiied.

4. T-he short stake P, with notch p, for holding the gate when closed,

A. B. MURRAY.
