Application filed May 20, 1914. Serial No. 839,851. 1

To all whom it may concern:

Be it known that I, JAMns Born, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Screws, of which the following is a specification.

This invent-ion relates to screws and in particular to those commonly known as stage screws. The primary object being to provide a device of this character which consists of a body for permanent use and means for securing an ordinary wood screw thereto, in order that the screw may be replaced when worn or broken without 113V".

ing to discard the body of the screw.

A further object of the invention is to provide a screw of this class whose body portion is constructed in such a manner that it may be used as a cork screw, a screw driver, a wrench, and in various other capacities.

The invention consists in the features of construction, combination, and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which:

Figure 1 is a side elevation of the body of the device, showing anordinary wood screw connectedtherewith; Fig. 2 is a longitudinal sectional view on line 22 of Fig. 1; Fig. 3 is a transverse sectional view on-line 83 of Fig. 2; Fig. 4 is a side elevation of a cork-screw adapted to be applied to the body; Fig. 5 is a similar view of a screwdriver which isadapted for the same use; Fig. 6 is alongitudinal sectional view through a portion of a modified form of screw body; and, Fig. 7 is a longitudinal sectional view on line 77 of Fig. 6.

In the drawings, the numeral 1 designates the body portion of the device, which is provided at itsupper end with oppositely extending, lateral wings 2 which permit the body to be grasped securely when operating.

the same. The body is provided medially with a longitudinal slot 3 opening through the opposite side faces thereof. A longitudinal opening 41 is provided in the lower end of the body in communication with the slot for the reception of the shank of an ordinary wood screw, such as is indicated by the numeral 5. The threaded portion 6 of the screw is adapted to project outwardly from the body, whereas its head 7 is countersunk within the inner end of the body opening 4.

gagem'ent within the head kerf of the screw -5, whereby the latter will be held against rotation in its connection with the body. An

operating screw 12 is rota tably mounted within the body opening v ith its head 13 disposed .eXteriorly thereof and with its innerend engaged within a socket 14 which is provided in the upper end of the securing member. The screw 12 extends through a threaded nut 15, which is mounted within the upper end of the body slot 8 and is held against rotation owing to its snug fit within the socket. Instead of providing the nut 15, the screw body may be modified, as shown particularly in Fig. 6. by providing a threaded opening in the upper end of the body in communication with the slot for the reception of the screw.

The body slot 3 is constructed of such length as to permit the introduction of the replaceable wood screw into the same when mounting the screw within the opening 4;. When it is desired to remove the securing member for the purpose of repair or to clean the same, the operating screw is withdrawn, whereupon the securing member may be removed through the body opening 13 and the extensions of the grooves 8.

In order that the body of the screw may be used also as a wrench for turning certain kinds of tools, non-circular openings 16 are provided inits wings. A screw driver extension 17 also is formed upon the outer end of one wing, and a tack-pulling extension 18 is formed upon the opposite wing, in order that the body may be used in the further capacities of screw. driver and tack puller. In Fig. 4, a cork-screw is shown constructed for use in the body of the device, and in Fig. 5 a screw driver is shown constructed for like use.

From the foregoing description, taken in connection with the accompanying drawings, it'should be apparent that I have provided a stage screw which is adapted to be used for a long period of time, it being necessary merely to replace the wood-screws, used in connection therewlth, as they become worn or otherwlse damaged. The

body of the deviceis also constructed so, that it may be used for several difierent purposes in stage work.

--What is claimed is:

1. In a device of the class described, the combination with a rotatable element having a head, of a body having an opening therein for the reception of the said element, a securing member mounted movably within the body and having one edge adapted for engagement with the head to secure the element against movement within the body, the said securing member being longitudinally notable with respect to the said element, and an operating screw adjustably mounted within the body in axial aiinement with the securing member for engagement with the end thereof opposite to the edge engaged with the said element.

In a device of the class described, the

combination with a rotatable element having a head, of a body provided with an elongated slot and with an opening therein in registration with one end of the slot for the reception of the said element, the side walls of the said slot being provided with longitudinal grooves, and a securing member mounted within the body slot with its side edges slidably engaged within the grooves, one end of the securing member being adapted for engagement with the head of the said element to secure the same against movement within the body, the body being provided further with an opening in communication with the opposite end of the said slot for passage of the securing member therethrough.

In testimony whereof I afiix my signature in presence of two witnesses.
