Specification of Letters Patent.
Patented Mar. 5, 1918.
Application filed August 2, 1915. Serial No. 13,105.
To (ZZZ whom it may concern:
Be it known that I, LAROY S. STARRETT, citizen of the United States, residing at Athol, county of Worcester, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Hammers, of which the following is a specification.
This invention relates to hammers and the like and particularly to a nail placing attachment therefor.
My present invention is in the nature of an improvement on my former patent, dated December 1, 1903, No. 745,973, and is designed to remedy certain difficulties in the use of said former hammer by doing away with the slot back of the nail head which was liable to get battered and close up, thereby interfering with the action of the spring.
The present invention contemplates a nail placer which will positively hold the nail (before starting) and will permit instant release of the nail after the starting blow is strufik by a simple movement of the hammer itse The construction and operation of my device will be more fully described in the specification which follows. In the drawings accompanying that specification, I have shown two forms of my invention which not only clearly illustrate the principles involved, but are in themselves constructions found satisfactory and well adapted to the requirements of manufacture. Throughout specification and drawings like reference numerals are employed correspondingly, and in these drawings:
Figure 1 is a plan section on the line 11 of Fig. 2, of a hammer equipped with one form of my nail placing attachment,
Fig. 2 is an elevation of the hammer head,
Fig. 3 is an end view thereof,
Fig. 1 is a detail section on the line 44. of Fig. 3,
Fig. 5 is a detail view of the spring tensioned pivot for the nail placer,
Fig. 6 is a perspective view of the operating device for the nail placer,
Fig. 7 is a view corresponding to Fig. 2 of a moulded form of nail placer,
Fig. 8 is an end view of Fig. 7,
Fig. 9 is a detail section on the line 9-9 of Fig. 10, and
Fig. 10 is a detail section on the line 1010 of Fig. 8.
In the form of my invention shown in Figs. 1 to 6, inclusive, the poll 1 of the hammer head 2 is provided along its top face with a shallow groove 3 in which the shank of a nail 4 is received with the head 5 of the nail received in a transverse recess 6 across the poll behind the groove 3. Beyond the recess 6 the poll is formed as an enlarged bearing 7 having a vertical driving wall 7 against which the head of the nail abuts. The bearing 7 has a transverse bore 8 and a longitudinal groove 9 across its top face connecting with said bore 8.
Protatably mounted in the bore 8 is a spring wrappedpivot pin 10. The pin "10 'is reduced between its ends and has a coil spring 11 wrapped about its reduced portion. One end of the spring 11 is received in a groove formed in the body of the pin and the other end of the spring is received in a groove formed in the bearing 7 Fastened to the pin 10 between its ends in any suitable manner is a nail holder 12. The nail holder 12 is received in the groove 9 formed in the bearing 7 with its free end normally lying in the groove 3 at the free end of the poll. The groove 9 and nail holder 12 therefore prevent lateral displacement of the pin 10 in its bore 8. The free end of the member 12 may be concaved slightly as indicated at 12 to conform to the shank of the nail.
Let diagonally through the poll 1 from the underside thereof is a bore 13 terminating at its lower end in an enlarged recess 14. Reciprocable in the bore 13 is a release pin 15 having a head 16 disposed to engage the under face of the member 12 and terminating at its opposite end in an enlarged head 17 exposed bevond'the recess 14 as an operating end and received in said recess 14: when pushed upwardly.
In using this form of my invention, the nail holder 12 is raised to permit the nail 4 to be placed in the groove 8 of the poll 1 with its head 5 received in the cross groove 6. The nail holder 12 may be raised by applying the thumb to the exposed end 17 of the operating device 15 and pushing said device upwardly. This lifts the member 12 and effects a partial rotation of the pivot pin 10 against the action of the spring 11. As soon as the pressure on the member 15 is lifted the spring returns the member 12 to frictionally clamp the nail, thereby moving the plunger 15 back to original position.
With the nail thus in position, a blow is struck with the hammer. The bearing of the nail head 5 against the vertical wall 7 of the bearing 7 drives the nail forward. The nail may then be removed from the hammer by simply drawing the hammer downward, the member 12 yielding to permit the nail to be disengaged. The nail is now started and may be driven in the usual manner.
In the form of my invention shown in Figs. 7 to 10 inclusive, the poll 1 is grooved along its under face as indicated at 18 and beyond its longitudinal groove has an enlarged cross groove 19 to receive the head 5 of the nail. The purpose of the under cut groove 18 is to receive a rail which is slightly bent between its ends. The rear side of the groove 19 extends as a vertical wall '20 against which the head of the nail bears and which wall delivers he impact to the nail in starting. Pivoted to the wall 20 between its ends at 21 is a finger lever The free end 22 of the lever 22 engages the nail and holds it in place against the under face of the poll. The opposite end of the lever 22 extends downwardly adjacent the hammer handle 2 as a thumb operating portion Fastened to the portion 23 is a blade spring 2a which is bent to conform to the portion 23 and has its free end in contact with the handle 2 of the hammer.
In using the nail placer of this form of my invention, the finger lever is pressed inwardly toward the hammer hand to cause its nail engaging portion 22 to rock downwardly away from the poll. The nail a is then placed in position against the under face of the poll 1 with its head 5 received in the groove 19. The finger lever is then released and the spring 2% throws the nail engaging portion 22 thereof up against the nail to frictionally clamp it in position. The nail is started by a blow with the hammer, the wall 20 driving the nail. The nail is released by moving the hammer away from the nail, the member 22 yielding slightly to permit this disengagement. The nail is then driven home in the usual manner.
lVhile I have shown and described my nail placer in its application to a hammer it will be understood that the device may be adapted to other tools without departing from the spirit of my invention.
Various other modifications in the form and construction of my device may obviously be resorted to without departing from the spirit of my invention if within the limits of the appended claims.
lVhat I therefore claim and desire to secure by Letters Patent is:
