MACHINE FOR DRIVING SCREW-EYES.

SPECIFICATION forming part of Letters Patent N 0. 670,361, dated March 19, 1901.

Application filed August 9, 1900. Serial No. 26,389. (No model.)

T at whom it may concern:

Be it known that I, EDMUND SATHER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn,

eyes shall be held in a magazine in quantities,

which magazine forms a portion of the tool, and means whereby the screw-eyes can be successively fed to an end of the tool and held firmly in position to enter an object and the screw-eye quickly and conveniently released from the toolafter the screw-eye is fixed in position. v

Another purpose of the invention is to so construct the tool that it can be operated by one hand in order that it may be used by awning makers and hangers to especial advantage, permitting them to quickly and conveniently place screw-eyes in position in places which have heretofore been reached with difficulty.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part .of-this specification, in which similar characters 'of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improved tool, illustrating a screw-eyev that has been driven into a support and in engagement with the tool, the tool being just about to be released from the screw-eye and a portion of the side of the tool being broken away to show the magazine, in which a number of screweyes are stored to be consecutively used. Fig. 2 is a longitudinal central section through the improved device 'on the line 2 2 in Fig. 1, showing the screw-eyes in the magazine in side elevation and one screw-eye in position to be entered into an object. Fig. 3 is a side elevation of the tool opposite that shown in Fig. 2, a screw-eye being shown in position to enter an object. Fig. 4 is a transverse section taken practically on the line 4 4 in Fig. 2. Fig. 5 is a transverse section taken practically on the line 5 5 in Fig. 2; and Fig. 6 is a detail perspective view of the carrier, which is arranged to slide in the tool and to receive and carry a screw-eye toa position for use.

The body A of the tool is usually madein two sections 10 and 11. The body may be given any cross-sectional shape; but preferably the forward end of the body is reduced in size and is circular in order that the two parts may be tied together'at this point by a ferrule 12, secured to the body by screws 13 or their equivalents. At the inner end of the body the two parts are shownattached together through the medium of a single screw 14, as is shown in Fig. 2.

r In the upper surface of the body a magazine-15 is produced in the section 10 at a point near the front end of said body. This magazine is of such shape and capacity that it willaccommodate'a number of screw-eyes B, placed one upon the other. Therefore the magazine 15 is provided with a rectangular section a, which extends longitudinally of the body, and a rear circular section a, as is shown in Figs. 1 and 2. The magazine extends to the inner face of the section 10, and a longitudinal channel is made in said inner face, the upper wall of which channel has a metal plate 17 secured thereto, usually by means'of screws 17 as shown in Figs. 2, 4, and 5. -In this plate 17, which may be termed a wear-plate, an opening 16 is made, conforming to the shape of the magazine 15, the opening 16 being in registry with the inner end of said magazine, so that the lowermost screw-eye that is placed in the magazine 15 will occupy such a position in the opening 16 in the said wear-plate 17 as is shown in Fig. 2. A longitudinal channel is also formed in the inner face of the section 11 of the body, as shown in Figs. 2, 4, and 5, anda wear-plate 19 is secured by screws 19 to the bottom wall of this channel, and as the channels in the inner faces of the sections 10 and 11 are in registry they jointly form a space 18 between the wear-plates of said sections, and this space extends to the outer or forward end of the body, as is illustrated in Fig. 2.

At one side of the bodyA the side walls of the space 18 are cut away, and at this pointa plate 20 is secured upon the outer side face of the body, as illustrated in Figs. 3 and 4,

the said plate having a longitudinal slot 21 made therein. A latch 22 in the form of a lever is pivoted at a point between its ends by a suitable pin 23 to the under or inner face of the slotted plate 20, as illustrated particularly in Fig. 3, and this latch-lever is adjacent to a longitudinal wall of the slot 21 in the plate 20, and said lever near its forward end is provided with an inclined projection 24, which normally extends across the slot 21 in the plate 20, and the forward end of the latch-lever 22 terminates in an inclined head 25, which normally extends entirely across the aforesaid slot 21 in the plate 20, as is also shown in Fig. 3. The latch-lever 22 is normally held in the position above mentioned by a spring 26, which has bearing against the head 25.

Preferably metal guards 27 are placed at the side portions of the parts defining the space 18, near the outer end of said space, as illustrated in dotted lines in Fig. 3 and in positive lines in Fig. 5. These guards are adapted to prevent wear of the parts defining the space 13, since acarrier28 is held to slide in said space between the wear-plates l7 and 19. This carrier, which is shown in detail in Fig. 6, is of metal and consists of a flat body, at the outer end of which a longitudinal slot 30 is made, which leads to a circular opening 29, the circular opening 29 being adapted to receive the circular portion of the screw-eye to be set, and the slot 230 permits the threaded shank of the eye to extend beyond the forward end of the carrier. At its rear end the body-plate of the carrier is preferably provided with an arm 31, which is shown at a right angle to the body-plate, and this arm extends out through the slot 21 in the plate 20 a sufficient distance to be readily engaged by a finger, as shown in Figs. 1 and a.

The top of the magazine 15 is closed by a hinged cover 31, which is provided with a keeper 32 upon its under face, and this keeper is engaged by a spring-controlled bolt 33, held to slide in a suitable recess in the upper portion of the section 10 of the body, beneath a plate 3a, in which a slot 36 is made, and the handle 35 of the bolt 33 passes out through this slot.

In the operation of the device the magazine is filled with screw-eyes B, and when the carrier or slide 28 is in its normal position within the body the opening 29 and slot 30 in the carrier will occupy such a position relative to the bottom portion of the magazine 15 that the lowermost screw-eye will gravitate into the said circular opening and slot. At this time the arm 31. of the carrier will be at the rear end of the slot 21 in the plate 20. When the screw-eye is to be placed in position in an object, the arm 31 of the carrier is forced toward the front end of the body until the said arm shall have passed the projection 24 of the latch-lever and bears against the forward At this time the front end of the slide or carrier 28 will have been carried to the front of the body, and the shank of the screw-eye will project beyond the forward end of the body, as shown in Figs. 2 and 3. The tool may now be directed as desired and the eye screwed into places which would otherwise be exceedingly difficult of access. After the screw-eye has been fastened in its support the body is drawn from the screw-eye, taking the slide or carrier a sufficient distance beyond the front end of the body to expose the eye portion of said screw-eye. Now by simply turning the body to one side the slide or carrier may be disengaged from the screw-eye. The slide or carrier is then drawn back into the body to receive another screw-eye for a subsequent operation.

When a screw-eye is to be introduced into a wall or other surface, the head of the screweye is within the casing, as shown in Fig. 2, and the arm 31 is in front of the projection 24, as is shown in Fig. 3, so that the necessary pressure to be exerted on the screw portion of the eye will not move the arm 31. After the eye has been screwed into the surface adapted to receive it the arm 31 is carried forward, forcing the head 25 to one side against the pressure of the spring 26, and the carrier for the screw-eye is correspondingly forced outward to the position shown in Fig. 1, whereupon by turning the body of the device to one side the head of the screw-eye is disconnected from the carrier of the slide. When the arm 31 is carried as far forward as possible and the slide is in position to release the screw-eye, the spring 26 will have been passed to an inactive position by reason of the curved portion of the head riding on the spring in direction of its free end. Therefore when the carrier or slide is to be drawn in to receive another screw-eye and the arm 31 is drawn toward the inner end of the body of the device the arm will pass over the projection 24-, which is then below the lower wall of the slot 21, and as the arm 31 is carried rearward it engages with the heel portion of the latchlever 2 and presses the said heel portion of the latch-lever down, thus bringing the forward portion of the latch-lever upward across the slot 21 and again restoring the spring to active position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A tool for driving screw-eyes, having a magazine in its body adapted to contain screweyes, a carrier having sliding movement beneath the magazine and provided with an opening adapted to receive the body and a portion of the shank of a screw-eye, the body of the device being provided with a passage for the carrier, having one dimension less than the greater cross dimension of a screweye, and a locking device for the carrier, substantially as described.

2. In a machine for driving screw-eyes, a body having a reservoir for screw-eyes formed therein, a carrier mounted to slide beneath the said magazine, said carrier having an opening therein adapted to receive the lowermost screw-eye in the magazine, the said opening being at an end of the carrier, the body of the device being provided with a passage for the carrier having one dimension less than the greater cross dimension of a screweye, an arm projected from the carrier and extending out through the slot in the body, and a latch-lever located at the said. slot, adapted to be engaged by the arm of the carrier.

3. In a machine for driving screw-eyes, a body which serves as a handle,having a magazine therein adapted to contain screw-eyes, the bottom of the magazine being open, a cover for the outer end of the magazine, a carrier held to slide in the said body beneath the magazine, said carrier having an opening at its end of a shape to receive the head and shank of a screw-eye, which opening is in registry with the bottom of the magazine when the slide is in its inner or normal position,

the body of the devicebeing provided with a passage for the carrier having one dimension less than the greater cross dimension of a screw-eye, a projection from the said slide, which is passed out through the slot in the said body, a latch-lever pivoted adjacent to the said slot, the latch-lever having an inclined head and an offset, both of which are adapted to be engaged by the arm of the slide, the said slide when carried outward to one position engaging with the projection from the latch-lever, causing the shank of the screw-eye to extend beyond an end of the body, the second outward position of said slide being such as to expose the entire screw- I eye carried thereby, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDMUND SATHER.
