PATENTED JUNE 4, 1907.

ful Screw-Eye Driver, of which the following ILBERT RHOADS, OF CHESTER, PENNSYLVANIA.

SCREW-EYE DRn/En.

Specification of Letters Patent.

Patented June 4i, 1907.

Application filed July 14,1906. Serial No. 326,293.

T a/Z whom, t may concern.

Beit known that I, HrLBEar C. RnoADs, a

citizen of the United States, residing at Chester, in the county of Delaware'and State of Pennsylvania, have invented a new and useis a specification.

This invention relates to a device for setting screw eyes, screw-hooks and the like, and has for its object to provide a device of this character that may be quickly engaged and disengaged with the article to beset.

A further object of the invention is to so construct the device that it can be operated by one hand in order that it may be used by awning makers and hangers to special advantage, permitting them to quickly and conveniently set screw-eyes and the like in places which have been heretofore reached with diculty.

In the drawings, in which the preferred form of construction is shown, Figure 1 is a perspective view, and Fig. 2 is a vertical longitudinal section thereof, a screw-eye being shown between the jaws in both views. Fig. 3 is a side elevation of a modified form of construction.

Similar reference numerals designate corresponding parts in the figures of the drawings.

Referring now to the drawings, 1 designates a handle having arecess or socket to receive a shank 3, said shank being enlarged and terminating in a rigid jaw 4, and provided at an intermediate point with a transverse shoulder 6. Associated with the jaw 4, is a movable jaw '7, having its inner end bearing against the shoulder 6 to prevent longitudinal Vdisplacement thereof. A flat spring V8 has one end fastened to the shank 3, and its free end resting upon the jaw 7 in advance of the shoulder 6. This spring normally holds the jaws closed so that a screw-eye, or the like, can be placed between the jaws and held firmly. Each jaw is cut out on its inner s'ide to form seats for the head of the screweye and prevent it from passing back too far. The jaws areprovided with registering openings 10, 10, adapted to receive a bolt 11, said bolt vhaving a cam lever 12 pivoted at one end and being screw-threaded for a portion of its length at the other end to receivean adjustinCr nut 13. 'The cam lever 12 is preferably b' rcated, as shown at 14, and adapted to straddle the bolt 1l, beingA pivoted thereto vby a transverse pin 15. This cam lever has i 1 a thumb hold 16 at the outer end., which forms a smooth and unobstructed surface for the thumb of the operator when compressing the jaws.

It will be noted that the jaw 7 is bowed as at 18, thus imparting a certain amount of resiliency or elasticity thereto, which will perniit the jaws to be drawn together after the nut 13 has been adjusted and the cam operated, thereby firmly clamping the screw-eye or hook in position to be set.

in operation, the tool is grasped in one hand, the jaws are then spread and a screw eye, or the like, is placed in the seats. The spring 8 will hold the jaws yieldingly together, so that a screweeye or the like, of any size can be placed tliereinand held rmly, thus leaving the operators hand free to ad just the nut and. force the cam lever back, and firmly clamping the article t-o be set. in other words, the spring 8 provides a light pressure to temporarily .hold the screw eye in the seats of the jaws, but when it is desired to set the screweye, it is necessary to operate the clamping means comprising the cam lever, bolt and nut to compress the jaws around the head of the screw-eye.

` Any suitable-type of handle -may be ernployed in connection with the mechanism, for instance in Fig. 3, the said mechanism is shown connected with a spiral actuating handle la.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A screw gripping and driving tool, coniprising a pair of jaws, an adjustable clamping' device operating in conjunction with said jaws to lock the jaws firmly in position, and separate means for holding the jaws together by a yielding pressure.

2. A screw gripping and driving tool, corn prising a pair of clamping jaws having their clamping ends held yieldingly together, an adjusting boltl carried by said jaws, and a clamping lever mounted on said bolt and adapted to hold. the clamping jaws rigid when operated.

3. A screw gripping and driving tool, comprising a pair of jaws having seats at their clamping ends, a spring bearing on one of the said jaws to normally hold them closed, an adjusting bolt connecting said jaws, and means for clamping the jaws together, said means being mounted on the bolt.

'4. A screw gripping and driving device IIO comprising the rigid jew having a sent in its outer end, the resilient jaw having e. corresponding seat' in its outer end, mea-ns for holding)r the resilient jaw against the rigid law hy a yielding pressure to admit of the temporary holdin@ ol" an article in the seats o1u the jaws, and c aniping Ineens 'for looking the jews together whilethe article is so held.

5. A screw gripping and drivi g tool, e0inprsing e, rigid jaw having' si hhlndle et one end and n shoulder intermediate of its ends, a llexil'ile i:wwhowed outwardly from the rigid having one end sea-ted ageinst the sl'iouhler ol' the other1 jew, the outer endg of both jaws having corresponding seats, a, spring yieldingly holding the jaws in engagement, and clamping Ineens including a bolt passed through both jaws, a nut adjustable on one end of the bolt and engaging the ilexible jew, and a cam mounted on the opposite end ofthe bolt and enguoing the other aw.

In testimony, that l. claim the foregoing as my own, I have hereto affixed my signature in thepresenee of two Witnesses.
