IMPROVEMENT IN GATES.

TO ALL WHOM IT MAY OONOERN:
Be it known that 1,'JOHN J. PnLLETT, of Oconomowoc, in the county of Waukesha, and State'of Wisconsin, have invented a new and improved Gate; andvI do hereby declare that the following is a full,.clear, and exact description of the construction and operation ot' the same', reference being had to the annexed drawings, making a part of this speciiication, in which- Figure 1 is a side elevation.
Figure 2 is a cross-section.
This invention relates to the class of farm-gates which are expanded and contracted longitudinally in order to close or open them, by means of the device known as Jacobs Ladder, and consists in enclosing said ladder between the bars of a sliding frame, by which the gate is greatly strengthened, and at the saine time rendered 'l more beautiful in appearance.
In the drawings, ct a represent the Jacobs ladder; B, the post against which the gate closes; C, the post to which it is hung; D D, guide-posts, of any suitable height; E E, posts that support the shaft by which the gate is opened or closed; F, the shaft referred to, having a pulley, G, and an arm, H, attached to it, and I a cord, passing once or more around the pulley or wheel G, to one point on the rim of which it is fastened ,to prevent slipping, and having its ends attached to the extremities of the gate. By turning the crank in one direction, the cord I draws the gate to the right, as seen in fig. I, and leaves the way open; and by turning the crank in the opposite direction, the gate is forced tothe left and closed. The arms HH are conneted together by a rod, 7L, and are attached to the shaft by a loose joint, which permits them to be roclied to the right or-left, as seen by the blackand red lines in g. 2. By this means the gate may be securely locked whenl closed, it being only necessary to bring one of the arms H H behind and in contact with a pin or projection, h', fixedto one of the posts E E. The projection t may be in the form of a hook, if desired, whereby it will more securely hold the arn1,'and the side opposite to the concave may be bevelled or inclined to facilitate the locking of the device. It will only be necessary to provide one locking-pin or hook, as the arms can both be operated from either side of the gate by means of the connecting-rod 71,. .y
The bar a, which. at its lower end is pivoted to the postv C, is attached at said pivot by a xed hinge, c. The bar in connection with it, that is pivoted at its top to thesame post, is hinged to said post by means of a pivoted arm, m, one end of which is attached to the post, and the other to the bar n, as seen in tig. l. As the Jacobs ladder is expanded or contracted in length, the position of the two bars connected to post O will be changed, sometimes being more and sometimesless vertical, and the arm m will rise and fall, accommodating itself to this change of position.
The main feature of the invention, however, consists in providing an enclosing-frame, composed of the upright standards S- S', the latter outside of the post C, and the fermer inside of the post- B, united together by longitudinal rails T 'I1 T2, which extend from standard to standard, on both sides of the ladder,henclosing it betweenthem. A pin, T, passes through the middle rail T1, and the two bars a a, that stand adjacent to theA standard S, that being the only point at which the ladder is connected with the enclosing-frame. The ends of the cord I are attached to the standards S S, and slide the enclosing-frame back and forth, the ladder inside of the frame contracting or expandingin proportion to the movement of the frame.
I am aware that gates havefor many years been constructed on the Jacobs ladder principle, but without the enclosing-frame. They have therefore been weak and easily racked out of position, besides being liable to get out of repair. By the use of the frame, however, the gate is greatly strengthened and supported, besides being rendered more agreeable to the eye. I do not broadly claim theuse of such ladder, but
What I do claim as my invention, and-desire to secure by Letters Patent, is-
I. The combination of the pivoted bars a a with the enelosingframe S S T 'lL T1, when operating substantially as and for the purpose set forth.
2. The combination of the arms H H, connecting-rod il., and locking-pin it', when used in connection with a sliding gate, asabove described, and with the wheel and cord for opening und shut-ting it, as a device for securely locking said gate, in the manner described.
To the above speciiication of my improvement, I have signed my hand, this eighteenth day of February, i868.
JOHN J. IELLETT.
