R. H. RICH. INSULATED, BINDING POST.
No. 498,407. Patented May 30,1893.
Uri 25 525 UNITED STATES PATENT OFFICE.
RICHARD H. RICH, OF BEVERLY, MASSACHUSETTS.
INSULATED BlNDlNG-POST.
SPECIFICATION forming part of Letters Patent No. 498,407, dated May 30, 1893.
Application filed July 15, 1892. Serial No. 440,133. (No model.)
To all whom it may concern.-
Be it known that I, RICHARD 1I.R1oH,a citizen of the United States, and a resident of Beverly, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Insulated Binder-Posts, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to improvements in insulated binder posts for electrical purposes and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a front elevation of the invention. Fig. 2 representsa top plan view showing the head of the binder screw removed; and Fig. 3 represents a central longitudinal section on the line 3-3 shown in Fig. 1.
Similar letters refer to similar parts wherever they occur on the different parts of the drawings.
A represents a suitable plate of a dynamo, electric motor or other machine or device to which the binder post is to be secured in an insulated manner.
The improved binder post consists of a block 0 made of insulating material such as for instance hard rubber, porcelain, &c., said block having a vertical perforation C adapted to receive the binder screw D having a knob or head d at its upper end as shown. In practice I prefer to secure within the upper end of the, cavity 0 an internally screw threaded sleeve 0" in which the screw D is working. The lowerend of the screw D is provided with a cup or washer E made of rubber or other suitable non-conducting material.
C is a lateral recess or perforation in the block 0 in which one end of the electric wire F is inserted as shown in Fig. 3.
G is a metal screw secured to the lower part of the block 0 and having its upper end adapted to serve as a metallic support for the wire F which is clamped in position between the insulated cup or washer E and the upper end of the metal screw G as shown in Fig. 3, thus establishing a metallic connection between said wire and the screw G, and insulating the binder screw D from the said wire F, thus enabling the screw D to be manipulated and adjusted without danger of giving shocks to the operator.
The screw G is preferably secured to the plate A by means of a suitable nut g and insulated from said plate by means of a flanged sleeve H made of rubber or other insulating material as shown in Figs. 1 and 3.
I is the circuit wire secured in a suitable manner to the lower projecting end of the screw G as shown in Fig. 3.
After the binder post has been secured to the plate A and the wire I attached to the screw G, I may prefer to inclose the lower end of the screw G, where it is united to the wire I, in a mass of soft cementor equivalent material K as shown in dotted lines in Fig.
By making the block 0 of insulating material and having the lower end of the binder screw D provided with an insulating material E, the said screw may be adjusted for securing or releasing a wire Without any danger whatever to the operator.
The screw G, as stated, is properly insulated from the plate or support A and it will thus be seen that a circuit between the wires F and G can instantaneously be established simply by inserting the wire E into the cavity 0 of the non-conducting block C and forcing it by means of the insulated binder screw D against the upper end of the metal shank or screw G as fully shown in Fig. 3.
The device is useful for all electrical purposes where a high tension circuitor power is employed.
Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- The herein described insulated binder post consisting of an insulating body 0 having an adjustable binder screw with insulating pressure cup or washer, a side recess adapted to receive one end of the wire and a metallic shank or screw for establishing electrical connection between the wire terminals, substantially as herein set forth and described.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 7th dayot' July, A. D. 1892.
RICHARD H. RICH.
