INSU LATED RIVET.
SPECIFICATION forming part of Letters Patent No. 483,806, dated October 4, 1892.
Application filed May 2, 1892. s ial No, 431,402. (No model.)
To all whom it may concern:
Be itknown that I, WILLIAM S. HULL, a citizen of the United States, residing at Sheffield, in the county of Colbert, State of Alabama, have invented certain new and useful Improvements in Insulated Rivets, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention has relation to rivets and analogous devices which are intended for the connection of plates or plies of material which are electrically conducted; and the object of the invention is to provide such articles with a non-conducting sleeve, jacket, or covering, whereby the device itself will be electrically separated from the plies or plates which it serves to connect with each other as a mechanical structure.
In the construction of jails, vaults, safes, and other structures formed of different plies or layers of plates or bars and requiring the connection in some instances of single bars or plates with each other, wherein electrical alarms or safety devices are employed, it is essential in many instances that the plies, bars, or plates which are mechanically connected shall be electrically separated or iii-' sulated from each other. To comply with this requirement by the 01d method of the application of insulating material within the bolt-openings and rivet-holes of portions to be connected mechanically, and in case of the connection of more than two plies to separate an intermediate ply from contact with the rivet or bolt by an enlargement of the hole in that ply as compared with the holes in the outer plies, a great saving in time and labor expended in constructing the before-mew tioned class of structures is accomplished by my present invention, which consists in the provision of rivets and analogous devices with a covering, sleeve, or jacket of paper, parch' ment, or any other suitable insulating material, which is secured in any suitable manner to prevent an undesigned separation therefrom.
I have illustrated several of the many forms of the invention which may be adopted to suit the particular place of use, requirements, or shape of rivet required. The sleeve, jacket, or covering is to be limited in its extent in ac cordance with the necessities of each case, and in case the rivets are to be heated when applied asbestus or any other non-combustible material can be employed, as the material of the sleeve, jacket, or covering. As to the1nannor of attachment it may be varied in accord ance with the material employed and rely upon frictional contact, adhesion, or insetting, either partially or wholly. In some instances the insulating sleeve, jacket, or covering may extend beyond the head or the upset-point of the rivet, or the mere interposition between these parts of the rivet of the insulatingjacket will suffice when it prevents contact of the rivet with the parts which it joins.
Other objects and advantages of the inven tion will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.
Some of the forms of the invention are illus trated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a longitudinal section through a rivet of one form. Fig. 2 is a like view of another form. Fig. 3 is a side elevation of still another form. Fig. 4 is a like view of another form. Fig. 5 is alongitudinal section with the insulating material inset. Fig. 6 shows another form with the jacket inset. Fig. 7 is a cross-section through any of the rivets.
Like letters of reference indicate like parts throughout the several views where they occur.
The rivet A may assume any form required by the nature of its use. Theinsulating jacket, sleeve, or covering B may extend for the entire length or only a portion of the length thereof. This will be determined by the char actor of the work in which the rivet is to be employed. This jacket or sleeve may be held to the rivet by frictional contact, adhesion, a cement, or any way desirable. The covering will be of a material dependent upon the na ture of the use of the rivet. In work where the rivet is to be heated the covering should be of asbestos or some analogous non-combustible material. In Figs. 3 and 4 the jacket or sleeve is held around the body of the rivet 2 eeasos and does not extend quite to the end thereof, so that when the end of the rivet is upset the metal Will be prevented from contact with the metal of the plate or bar by the said covering. In Fig. 3 the metallic head is conical and the covering prevented from moving toward the head by the tapered wall of the rivet. In Fig. i this movenientis prevented by the shoulder a of the head. In Fig. l the sleeve or jacket is shown as extended upon the taper of the head. In Fig. 2 it is shown as flanged at the head end of the rivet, as seen at b, the flange lying against the shoulder a of the head and may extend beyond the same, as indicated by dotted lines in said Fig. 2,to avoid any possibility of the metal of the head coming in contact with the plate or bar with which it is used.
The jacket or covering may be set into a WTLLIAM S. HULL.
