Application February 4, 1949, Seri'ai No. 7%516 1 Claim. 1
My invention relates to screw drivers and more particularly to a type of screw driver that will retain contact with the screw.
An object of my invention is to construct a screw driver that will provide frictional resistance with the vertical walls of the slot in a screw head, thereby permitting the operator to place the screw on the screw driver and in position in hard to get at places.
Another object of my invention is to construct the head of a screw driver in a manner to provide resiliency at all times so that the contact points or blades are urged apart from one another.
Still another object of my invention is to construct a screw driver head in which the contact blades may be easily inserted into the slot or grooves of a screw head.
A still further object of my invention is to construct a device of the character described that is practical, economical to manufacture and is efficient for the purpose for which it is inended.
It is manifest to anyone familiar with the art of using screw drivers that it is sometimes difficult to place a small screw or bolt in position, and it is therefore advantageous to support the screw by means of a screw driver when placing the screw into a remote corner or position in a congested assembly. With the device as de scribed it is a simple task to insert the blades of the screw driver head into a slot of a screw and retain the screw in position on the screw driver head by means of frictional contact of the blades with the vertical walls of the slot, thereby eliminating the necessity of any mechanical accessories on the screw driver for retaining the screw onto the head.
Other and further objects of my invention more apparent as the description proceeds and when taken in conjunction with the drawings in which Figure l is a perspective side View of the assembled screw driver.
Figure 2 is a side view or" the head of the screw driver as shown in Figure 1.
Figure 3 is a front View of the head or" a screw driver as shown in Figure 2.
Figure 4 is a fragmentary perspective View of a screw driver head and screw, illustrating the manner employed to insert the blades into the slot of a screw, and
Figure 5 is a fragmentary view of the blades of the screw driver head inserted into the slot of the screw.
Similar characters of reference indicate corresponding parts throughout the several views, andreferring now to the same, the character I!) shows a screw driver stem provided with a conventional type of handle H fastened in any serviceable manner.
The depending end of the stem Ii] terminates into a head which consists of an annular portion 2 having an aperture [3 extending through its entire cross-section. The lower end of the annular portion l2 extends outward to form two blades shown as I4 and I4 and shown separated from one another by means of a slot or space l5 extending from the extreme outer end of the blade I4 to the aperture 13. The outer peripheral surface of the annular portion I2 terminates into an arcuate contour shown as 15 at the junction with the blades l4 and I l, thereby providing resiliency for the blades.
Obviously, the length of the blades or their cross-section, or the diameter of the slot l5 may vary to suit the particular type of screw driver and the purpose for which it is intended.
The slot l5 provides a space between the blades M and I l and the arcuate construction of the head supporting the blade provides a means of urging the blades away from one another to a distance equivalent to the width of the slot.
When the tips or extreme ends of the blades are inserted into a slot I! in the screw shown as iii in Figures 4 and 5, the outside diameter of the spread blades being greater than the width of the slot I? will cause the blades l4 and M to be forced toward one another, thereby narrowing the diameter of the slot or space l5 between the blades and causing the outer surface of the blades to frictionally engage the vertical walls of the slot I! in the screw.
The arcuate contour and construction of the head provides resiliency to cause the spreading inclination of the blades.
In Figure 4 I illustrate the manner employed for engaging the blades H!- and I4 into the slot li. By forcing the blade M against the shoulder of the slot i! in the screw, it will cause the space :5 to narrow, thereby permitting the other blade !4 to enter the slot ll when the screw driver head is brought into alignment with the screw shown as l8.
In the chosen embodiments of my invention there are present many features not heretofore disclosed in the prior art, and although I have shown a specific construction and specific contour and arrangement, I am fully cognizant or" the fact that many changes may be made with- 3 out afiecting their operativeness, and without departing from the spirit of my invention or the scope of the appended claim.
Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States is:
A device of the character described, said device being fabricated of a single piece of material shaped to define an elongated cylindrical stem, one end of said stem including a head, said head being flattened and enlarged and being provided with a centrally disposed aperture, said head having a pair of outwardly extending, resilient blades spaced parallel to each other and spaced apart from one another defining a slot extending from said aperture to the ends of said blades, said slot being arranged in alignment with the longitudinal axis of said stem, said blades being mounted for movement toward and away from each other, the outer periphery of said head extending outwardly and arcuately so that there is provided a gradual diminishing of the cross-sectional area of the head terminating 4 in said blades. the distance from the aperture to the outer edges of the head being greater than the thickness of the major portions of the blades, the longitudinal axis of said aperture being arranged at right angles to the longitudinal axis of said slot.
