The novel features of my invention are hereinafter fully described and claimed.
In the accompanying drawing, whi h illustrates the preferred embodiment of my invention j Fig. 1 is aside elevation of my improved attachment shown mounted on a screw driver and engaged with a screw.
Fig. 2 is a view similar to Fig. 1,"'but viewed from another side.

Fig. 5 is a bottom end. viewof the attache mentwith the parts disposed as in Fig. 3.
Similar reference characters designate similar parts in the different views.
The attachment is provided with two resilient arms 1 and 2 which are respectively attached to and supported by two clamping members 3 and 4 adapted to releasably receive and to be clamped on the shank 5 of a screw driver of usual type having a handle rag-.1. seri l No. mama y i For normally forcingthe members 3 and 4 to the clamp ng posit lonpa coil spring 11 ay e lw e P fle Q an a e ts end respectively bear ng; againstthe outer sides a j of the members 31% 4. j
Forholdmg the screw, the arms 1 'and2, atthelr lower or outer ends are respective ther and'a ag n t9 S pp r h r aner or upper s des the. head 9 of thescrew with the blade 7 inpthe slot S ofthe screw. as hown in Fig. 1. ,The jaws 12 and 13ers Pmv de wil We inwardly er endin J va 12 and 1 W hraem V r e pe t ve Pro ded n hei inn d e i with registering recesses 14 and15 adapted to wer w en t #1 v ar in the. closed position shown in solr lines in 1, the hank m t the ew Th a ms l n 2 in e med e f t e mem er 3 nd 4. a d he iaw a d 13 r respectively fulc t med qnthe the screw driver. or t purpose, the arms and 2 re P vi d res e t e w h wa inwardly extending pro ections 17. and .18. which form respectively tulcra for the arms.
n t e aperat en eft a i wip oa; he a chmen havin halit mm. as 3 e s hared 0a and sleeping the s haekfi at he screw drlver, the arms 1 an are compressed intermediate of the fulcra pro'ec tions 17 and 18 and the members 3 an 4, thus spreading apart the lower portions of the arms to the open position shown in dotted lines in Fig. 1. s j
The jaws 12 and 13 are then permitted to receive in their recesses 14 and 15 the shank 16 of this screw, the head 9 of the latter resting on the upper sides of the jaws 12 and 13. i
The screw driver is then adjusted in the members 3 and 4 so that the blade 7 enters the slot 8, as shown in Fig. 1. The screw will now be firmly and securely held so that the screw driver may be operated in the .usual manner to screw the screw into the position it is to occupy.
After the screw has been properly started, the arms 1 and 2 above the fulcra projections 17 and 18 may be pressed toward each other, whereby the jaws 12 and 13 will move apart so as to be disengaged from the screw.
The members 3 and 4 may then he slid upwardly on the shank 5 to remove the jaws ,from a position in which they would interfete with the screwing of the screw to itS head in the object in which it is mounted.
To engage another screw, the members 3 and 4 are then slid downwardly on the shank 5 until the jaws 12 and 13 are again beyond the lower end of the blade 7. lhe operation, already described, of engaging another screw with the jaws is repeated.
Whenit is desired to utilize the attachment in the removal of screws from positions which they may occupy in an object, the members 3 and a are slipped on the shank 5 toward the handle to a position in which the jaws 12 and 13 will be at the innner side of the end of the blade 7. The screw driver blade is then inserted into the slot 8 of the screw which is to beremoved, and then turned to unscrew the screw to a position in which jaws.12 and 13 may be dis- The screw driver is then turned so as to remove the screw from the object, after which the jaws 12 and 13 will support the screw until it is removed therefrom by hand. I do not limit my nvention to the struc ture shown and descrlbed, as many moonlications within the scope of the appended claims, may be made without departing from the spirit of my invention.
lVhat I claim is: v
1. A screw driver attachment comprising two resilient arms having respectively two jaws arranged to releasably embrace a screw with its slot receiving the blade of a screw driver, and means supporting said arms adapted to slidably engage and releasably clamp the shank of the screw-driver, said arms intermediate of their jaws and said supporting means being-adapted, when so supported, to bear directlyon and be fulcrumed against opposite sides of the screw driver shank, and arranged when compressed between the tulcra and said supporting means to swing said aws from their normal screw engaging positions.
2. A screw driver attachment comprising two resilient arms hating respectively two jaws arranged to releasably embrace a screw with its slot receiving the blade of a screw driver, and means supporting said arms adapted to slidably engage and releasably clamp the shank of the screw driver, said (iii arms intermediate of their jaws and said supporting means having respectively two inwardly extending. projections adapted to bear directly on and befiilcrumed against opposite sides of the screw driver shank, said arms being arranged when compressed between said projections and said supporting means to swing said jaws from their normal screw engaging positions.
In testimony whereof name to this specification. V r NUNLEY H. STONE.
