'HENRY THOMAS G-ENTRY, OF. KALISPELL, MONTANA SCREW DRIVER;
. Application filed. September 30, 1929. Serial No. 396,154. g
The present invention relates to a screw driver and more particularly to a device for holdingsc'rews orj'bolts firmly to the screw driver so that the maybe screwed into mate rial with case an i not be liable tobe dropped or to soar the surface of the material and for inserting screws and boltsin hazardous and inaccessible places'as'well as in plain open work. .7
Another very important object of the invention resides in the provision of a device of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable easy to manipulate, compact and convenient in its arrangement of parts, thoroughly efiicient and reliable in use, and otherwise well adapted to the PHI? pose for which it is designed.
With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will y, be hereinafter more fully described and v claimed.
In the drawings:
Figure 1 is a side elevation of a screw driver showing my attachment mounted thereon.
Figure 2 is a longitudinal section of the device as applied to the shank of the screw driver; the shank being in elevation.
Figure 3 is a perspective view of the barrel. I Figure 4: is a cross sectional view taken sub- 5 stantially on the line 44: of Figure 1.
Figure 5 represents a cross sectional view taken substantially on the line 55 of Fig-.
substantially on line 66 of Figure 1 with the screw omitted. V
Figure 7 is a perspective view of the trigger device.
Referring to the drawings in detail it will be seen that the numeral 5 denotes a screw driver shank terminating at one end in the usual blade 6 and having on the other end the usual handle 7. An external sleeve 8 is formed on the shank 5 adjacent the blade 6 This sleeve is externally threaded and held in place by means ofapin9.- i
"A. sleeve 10' is internally threaded and threadeolly engages withthe sleeve 8-. The
By-pulling the barrel 11 down as far as it will go so that the stop lugs 12 abut the upper end of the sleeve lOand then unscrewing the sleeve 8 upwardly out ofthe sleeve 10'itwil1 be seen thatthe bladefi may be moved Sllf". 76 ficiently up-into the barrel so that 'a'screw head may be inserted through the opening 16 with'the' shank of the screw in the slot 15 and then the shank 5 may-bemoved downwardly causing the slidingof'the sleeve 10 11135116 barrel 11 until the blade is engaged 'in the'kerfof the'screw head and thus the screw is securely mounted in the device and may be driven home in the materialuntil the bottom ll abuts the material; 7
When this has occurred then the shank'5 may be moved'upwardly slidingthe sleeve 10 in the barrel 11 todisengage the blade 6 from' the kerf ofthefhead and then .the barrel will he slid transversely of the screw to free the bottom 14 aswill be quite ap- Parent. I
Then the shank 5 maybe moved downwardly to bring the-sleeve 10 to the bottom ll-and if necessary the shank may be turned 96 to thread the sleeve 8'into the sleeve 10. until the blade Gissuflicient-Iy projected downwardly throughthe slot-15 to be used as an ordinary screwdriver. "In order to permit the release of the screw driver from kerfof screw when operated, a latch such as is generally referred to by numeral" 17 is employed. The barrel 11 has an extension 18 to which the trigger 19v is v connected by means of apin 20. The pin 100 passing through the trigger rockably supports the trigger, so that the spring 21 supported by the extension 18 and bearing against the upper portion 22 of the trigger will swing the said trigger so that the enlarged end portion 23 will be urged against the barrel 11 so that its laterally disposed tooth 24 will engage through the opening 25 in the barrel in the manner clearly shown in Figure 2. The screw driver is operated in the following manner: Release latch 17 and push barrel 11 down (Fig. 2) as far as it will go in order to space the screw support 14: from the edge of the blade 6 so that the blade will not interfere with the insertion of the screw. If this movement is insuflicient to permit the insertion of the screw the shank may be further advanced by rotating it with respect to sleeve 10 which latter is held against rotation and upward movement by frictional contact with the studs 12. Now insert the screw through the slot 15. With the latch still released move barrel 11 up until blade engages the kerf of the screw. Rotate shank 5 so as to separate the two sleeves 8 and 10 until sleeve 10 reaches the position shown in Fig. 2. Per mit the latch to engage sleeve 10. The screw is now locked against displacement between the support 14 and the edge of the blade.
It can thus be seen that the screw driver will be released from the kerf of the screw when the said latch is operated.
It is thought that the construction, operation, utility and advantages of this invention will now be, quite apparent to those skilled in this art without a more detailed description thereof. v
The present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumeratedas desirable in the statement of the invention and the above description.
It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is:
1. In combination, a screw driver shank provided with a blade, a sleeve fixed on the shank and externally threaded, a sleeve internally threaded and engaged with the first mentioned sleeve, a barrel slidable over the second mentioned sleeve and having inturned lug stops to engage one edge of the. internally threaded sleeve and formed with a bottom having a slot therein and said barrel having an opening merging into the slot, and latch means on the barrel for engagement with the said second-mentioned sleeve to prevent outward movement thereof with respect to the barrel during the operation of the screw driver, said means being releasable to permit such outward movement for disengaging the screw driver from the kerf of a screw.
2. in combination, a screw driver shank provided with a blade, a sleeve fixed on the shank and externally threaded, a sleeve inof the trigger, said proi'lection being adapted for disposition throug an opening in the barrel to act as a stop for the second mentioned sleeve, and a spring engaged with the said trigger for maintaining the trigger and the projection in engagement with the said sleeve.
In testimony whereof he alfixes his signature.
HENRY THOMAS GENTR-Y.
