EDVARD GRANDY, OF EVERETT, MASSACHUSETTS.
HAND TACK-DRIVING MACHINE.
SPECIFICATION forming part of Letters Patent No. 609,426, dated August 23, 1898.
Application filed March 30,1896. Renewed January 22, 1898. Serial No. 667,661. (No model.)
T0 a/ZZ whom. it mja/y concern:
Be it known that I, EDWARD F. GRANDY, a citizen of the United States, residing at EV- erett, in the county of Middlesex and State of Massachusetts, have invented certainxnew and useful Improvements in I-Iand Tack- Driving Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in hand-operated tack-driving machines which materially assist in their manipulation.
This invention is shown in combination with the tack-drivin g machine patented June 27, 1893, by Crisp and J unkins and numbered 500,225, to which reference is hereby made.
In the drawings, Figure lis a side'elevation of a tack-driving machine, showing the driving-hammer mounted thereon in operative position. Fig. 2 is the same side elevation, partly in section, showing the manner of connecting the ham mer to the plunger of the tackdriving machine.
This improved machine is constructed as follows:
The shell A of the maohinehereinbefore referred to is iitted to receive an outer shell l, adapted to be grasped by the hand of the operator. The upper end of the plunger B is also fitted to the interior of the shell l, where it is secured to the shell 1 by the capscrew 2, as shown in Fig. 2 of the drawings.
The raising-spring B2 may be-dispensed with, if desired, as the Weight otthe parts connected to the shell A is sufficient to cause said shell to assume the position shown by the drawings, when the shell l is grasped by the hand of the operator and the machine held vertically, in which position the machine is ready to drive a tack, which I consider an equivalent construction.
The operation of. this machine is as follows: With the machine heldin the hand of the operator by the sleeve l the operator places the tack-delivery nozzle Fupon the work. at the place it is desired to drive a tack and by a downward motionof the hand on thesleeve ldrives the tack. The weight of the `sleeve 1 acting upon the plunger B as a hammer and the velocity given it by the operator governs at will the depth the tack is driven. The act of removing the machine from the work causes the parts to assume their normal position ready to drive another tack.
The advantages of the above-described invention are that it leaves one hand of the operator free for any desired manipulation, and at the same time does not materially increase the weight of the machine, and yet increases the facility with which it can be grasped and operated.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
In a hand tack-driving machine, a sleeve mounted to reciprocate over the part of the machine usually grasped by the hand of the operator, and rigidly fixed to the hollow drivingplunger,in combination with said plunger having a spring inclosed therein and a rigid nose, substantially as set forth.`
EDWARD F. GRANDY.
