Letters Patent No. 112,904, dated March 21, 1871.
IMPROVEMENT IN GATES.
The Schedule referred to in these Letters Patent and making parl:A of the same.
To all whom 'it ina/y concern Be it known that I, PETER S: CRAWFORD, of Union, in the county of McHenry and State of Illinois, have invented an Improved Gate; and I d hereby declare that the following is a full and clear description thereof, which will enable those skilled in the artto make and use the same, reference being had to the accompanying drawing and letters marked thereon making a part of this description, in which- Figure l is a longitudinal elevation of my improved gate in position as when open.
Figui-e2, a longitudinal elevation of the gate when shut.
Figure 3, a transverse sectional elevation of the gate.l
Figure 4 shows a modification of theframe for supporting the levers.
The present invention relates to an improvement in that class of gates which is arranged to be opened without alighting from a'horse or vehicle, and which may be opened by a person on the ground; and
Its novelty consists in the peculiar construction and combination ofthe parts whereby the above operations are conveniently performed, as the whole is hereinafter fully described.
M M represent two posts, which are secured to a transversel sili, M', such a distance apart as will readily lallow a gate, N', to slidel back and forth between them.
The gate N consists of a frame, slats, braces, 85e., pnt together in the ordinary manner of making farmgates.
The only7 difference consists in extending the center rail I back far enough to reach two rollers, J, placed such a distance back from the posts as the gate is to more longitudinally, and in attaching an inverted double-inclined plane, Gr, to the under side of the top rail of gate, so that the latter, when so moved as to bring the apex of theplanes onto a friction-roller, H, the gate will open orshut, as the case may be, by its .own gravity.
In order to make the bar I as light as possible and yet strong, it is braced by thin strips of boards K; and in order to prevent the rollers J from wearing the fence-post L, a plate, J', of iron, is bolted to it, as
shown in figs. 1 and 2, the bearings of the rollers extending throngh the plate for better support.
'The means for operating the gate consist of arms D, Abrace G, levers A, and cords E and E. The arms D are rigidly attached tothe opposite sides of posts M, and are supported at their top ends by means of a curved brace, C, the object of curving it being to give room for the operation of the levers A when the gate is being opened. 'g
The levers A are jointed to the top ends of the braces D, and are connected to gate at F by means of cords E, so that when either lever is brought down with Aa quick movement, and forward in the opposite direction to which the gate is to move, the apex of the double-inclined plane G will be thrown past the roller H. The gate will then open or close, as the case may be, without the application of further power.
-IVhen a simple construction in the parts for snpporting the levers A is desired, diagonal arms and a horizontal brace-(in iig. 4) or tie may be used instead of 'parts D O, shown in g. 3.
vThe vadvantage gained in attaching the braces D to the posts M consists in their always being in the same position relative to the gate to'be moved. This is not the case when the levers are supported by posts pnt in the ground, Vinasmuch as the action of frost frequently upsets such posts and renders the levers in operative. j
A gate thus constructed and.- arranged is found to be very simple-cheap, and convenient, being readily operated by any person of ordinary strength, while, at the same time, it can be made by any farmer accustomed to build fences and ordinary swing-gates.
Having thus described my invention,
What I claim, and desire to secure by Letters Patent of the United States, is
4'lhe arms D attached to the posts M, in combination with the brace C, levers A, cords E, gate N', incline G, center piece I, rollers J H, and braces K, as set forth.
