GATE.

SPECIFICATION forming part ofV Letters Patent No. 239,077, dated March 22, 1881,

Application filed July 17, 1580, (No model.)

To all whom it may coacemf Be it known that I, ALFRED FRANCIS VRIGHT, of the city of Toronto, in the county `of York, in the Province of Ontario, Canada,

gentleman, have invented certain new and useful Improvements in Gates; and I do hereby declare that the following is a full, clear, and

' exact description of the same.

Myinvention has for its object the construction of a gate which shall be better adapted to the purpose for which it is intended than any of the gates in present use-viz.,that of a gate which will answer both for a villa and a stock gate-such a gate as would be suitable for the entrance-gate to a country residence, and also for an entrance-gate to parks and forgeneral purposes. i

My gate is a six-barred gate, but not limited to any particular number of bars, and can be of any ordinary height and width, ranging from twelve feet in width by four feet in height upward, a suitable size for ordinary purposes being about thirteen feet in width by four feet in height. It is made generally of pine wood. It is cheap and economical, and from the man-` ner in which it is constructed is much more durable than the gates in general use. It can be built from the refuse cuttings around a saw-mill, which are in many mills burned to keep the yard-room clean and free from interruption to the workingof the mill; or it may be made of iron or other suitable material.

My gate is constructed with the instile rising about two feet above the uppermost bar of the gate, and is preserved in its vertical position by a saddle-brace, the angular bars of awhich are secured to the uppermost bar of the gate and to the inner face of the instile, with strengthening-pieces interposed between, and having a tightening-key at the junction of the aforesaid angular bars for keeping the joints close and tight. At the top ofthe instile is a sloping plate, of cast-iron, with curved notches on the upper face, in which a cross-bolt rests. On each end of this bolt a tie-rod is secured, and stretching diagonally to the opposite flower corner of the outstile and lower bar of the gate, which tie-rods or truss prevents the gate from saggingat its outer end, and thereby secures the gate in its original and perfect form.

'below the middle main bar.

ening-pieces.

My gate is also constructed with an upright center brace, which bindsthe longitudinal bars all together by means ot' strengthening-pieces bolted to the bars, and intowhich the upright is mortised and secured by a key abone and A strong bolt passes down through the center of this brace, and binds the structure firmly and solidly together.

In the accompanying drawings, Figure l is a front elevation, and is drawn to a scale of about one-half inch to a foot, showing the form of the gate and the mode of construction thereof, showing, also, the saddle-brace built upon the inner face 'of the instile and the upper bar of the gate, and having interposed strength- Fig. 2 is a vertical section, on an'enlarged scale, showing the inner face of the instile, the section of the bars of the gate, and the bars of saddle-brace. Fig. 3 is also a vertical section, showing the inside face of the outstile of the gate and the section'of the bars of the gate, the upright pieces of the center brace, and the interposed strengthening keys and caps in connection therewith. Fig. 4 is a vertical section, enlarged, through bolt g; and Fig. 5 is a cross-section through line P P of Fig. 4.

a is the instile of the gate, on which is constructed the saddle-brace, composed of the following parts,`viz: upper angular bar, b, the under angular bar, c, the interposed strengthening-pieees d d cl d el', bolts a n a o, and key c. There are also shown the three main bars of the gate, h h It, and the three minor bars i i t', and the outstile t, and the upright center brace, e, composed of the strengthening-pieces lo k, one of which is placed below the upper loar,`

through this center brace, and when tightened up and the keys f' f are driven home the whole structure is made thoroughly strong and IOO secure, the bars of the gate partaking of the character of a girder.

As an additional means' of strength, two truss-rods, l l, stretch from the apex of the instile a diagonally to the lower corner of the gate at a', which prevents the weight of the gate from straining and opening the joints, thereby further assisting in retaining the gate in its perfect form.

From my Inode of construction, as describedfirst, the saddle-brace for strengthening the instile a; second, the center brace for binding together in one compact body the bars of the gate h h h and t' t i; and, third, the truss-rods l l, for taking the strain from the joints thereof-the gate is thoroughly secured from getting 'loose in the joints and out of form.

It will be observed from Fig. 3 that the upright bars ss in center brace, e, are made of two thicknesses, embracing and bolted to the minor bars i t' t', and mortised into the pieces lc 7c andff. The lower angular bar of saddlebrace is also of two pieces. side by side, embracing and bolted to the bar t', and mortised above into the under strengthening-piece, d, and below into the main bar h and the short upright piece d on the face of instile.

The plate on on apex of instile is shown to fall outward from the circle, scribed from under end of truss-rods Z Z, and having curved notches in its upper surface, in one of which the center bolt does rest, and when tightening the trussrods,if necessary, at any future time. the outer end of the gate is slightly raised and supported, and the upper center bolt placed in the next lower notch. The tightening up of said truss-rods may be done by the common pawl and ratchet when so preferred.

I reserve the right to make a future application for Letters Patent for the herein-described braces as applied to bridges and analogous structures.

What I claim as myimprovements in gates is as follows, namely:

1.. The saddle-brace', as constructed on instile a, and top bar, h, of the gate, composed of the following parts: the upper angular brace or bar, b, with upright piece d on face of instile a, the horizontal pieces d d, to Whichthese are secured, the under angular brace or bar, c, and pieces d d', to which it is secured, the key c', the bolts n n n n. truss l, and outstile t, as shown and described.

2. In combination with the horizontal bars, the center brace, e, composed of the parts s s, in two thicknesses, the caps and keysffff, caps k k, and the bolts o 0,19 p, t' r, and g, as shown and described.

3. The combination of the saddle-brace and center brace, as shown and described, with the truss-rods Z l, notched plate m, the instile a, outstile t. and bars h h h and t' t' t', for the purposes set forth.
