Referring toth'e drawings in" detail, the body portion -which is of tubulaii construction?{coin' prises side membersof -the body portion'beingdndieat'ed bythe'reference character I. r

The reference character 8 indicates the handle of the machine, by means of which the device is gripped, when in use.

Near the forward end of the handle 8 is an opening 9 through which the lever 10 extends, the lever l0 being pivotally supported on the ear II that extends forwardly from the handle, as clearly shown by Fig. 3 of the drawings.

The upper end of the lever 10 is bifurcated as at l2 and accommodates the pin l3 carried by the extension l4 of the actuating lever l5.

Rising from the top of the body portion are spaced plates l6, providing a support for the handle H which has pivotal connection with the plates, at 18. The handle I! is connected with one end of the actuating lever l5, by means of the link l8, the connection between the link I -9 the acru'etmgie er; *1 5,3 is thf' arim 2a which is fdr'm'd with "notch "2' r adapted. to ma e ta theshoulder'lz' forih'd'bjith notch '23 or th {The hammer 2-4 is mounted in the hammer seer-25 immits owren dtperi, t com mi'inicate with the bqdypor'tion "offthe, machinel SlotfZB isffor'm'dfinf'thefwall of the hammer bearer" arid "ac'oiiiihodatesifthe rming wh ch moves therethrough.

Fitted withiifth'ef fo w signs or the i Mi 'ib i iv Sandia bottom 6,3'thetop I8 barrel opening of a block 30 whi, h s, secured'i'n position, by means of the s'crew s iil that ex" 'efid through openings. in thebody riortioifaridarefseatedinithreaded es. dint'gral'with the block 30; is the barf?! that."extendsfiiearwardly within the" Body portion? theffree 'n'd'of the" bar-32; he'- mg ektnded'beyoiidthe"hddf'theBody beams. The block 30 is formed with a barrel opening dispensed vertically of the block, the opening being designed to receive the barrel 33, which rotates therein, between the bottom 6 and top 1.

The inner side of the block 30 is formed with a slot 34 that communicates with the barrel opening, providing a guideway for the tape 35 in which the pins 36 to be set by the machine, are held. The pins 36 are held in spaced relation with respect to each other within the tape, and are so arranged that as the tape is fed through the machine, the pins will be directed into the longitudinal vertical grooves formed in the barrel 33, as shown by Fig. 2 of the drawings.

A horizontal groove 31 is formed in one side of the block 30, and this groove 31 intersects the the block 30. The groove provides a guideway for the spring arm 38 which has a lug 39 formed at its free end, the lug 38 being designed to engage within the grooves of the barrel 33 to move the barrel with each reciprocating movement of the arm 38. The arm 38 is provided with an opening through which the spring finger 40' extends, the spring finger being secured to the arm 38 in such a way that the lug 39 will bev normally urged into engagement with the barrel 33.

Formed on the inner end of the spring arm 38, are spaced flanges 4| and 42 are vertically disposed and adapted by the lower tapered end of the lever I 0. For example, after the handle I! has been operated to set a pin, and the handle is released, the

to be engaged which flanges 4 in the body portion, a lug at one end of the spring arm movable within the grooves rotating the pin barrel with each sliding movement of the spring arm moving a pin held in the pin tape to a position under the hammer for engagement by the hammer, spaced flanges extending laterally from the spring arm, an operating handle, a. lever movable to engage the flanges reciprocating the spring arm, and means operated by they handle for setting the hammer and operating the lever.

2. In a pin setting machine, a body portion, a

vertically movable spring-pressed hammer operhandle I! is moved upwardly to the position as shown by Fig. l of the drawings, whereupon the y lever l0 engages the forward flange 4| as shown by Fig. 2, moving the spring arm 38 forwardly, resetting the arm in position to feed the successive fasteners below the driver upon the next actuation of the lever l7.

Due to the construction of the levers and arms, it will be obvious that when the handle I! is depressed, the lever Ill will engage the flange 42, moving the arm 38 in the direction as indicated by the arrow in Fig. 3 of the drawings. With this movement, it is obvious that the barrel will be rotated to bring a pin directly under the hammer 24.

A setting pin indicated at 43 extends from the hammer 24 and is so located that it will pass through one of the grooves of the barrel 33, forcing the pin held within the groove, from the machine, setting the pm;

In the operation of the device, thehammer 24 is moved upwardly by the upward movement of the forward end of the actuating lever IS. the arm moves to the limit of its upward movement, the arm contacts with the upper end of the slot 26, causing the arm 20 to move to disengage the hammer 24, whereupon the hammer is snapped downwardly, under the action of the spring 28, setting the pin which falls directly under the setting pin 43.

It will of course be understood that the tape in which the pins to be set are held, is fed forwardly by contact with the barrel 33, as the operation of the handle I! is repeated.

What is claimed is:

1. In a pin-setting machine, a body portion, a vertically movable hammer mounted at one end body portion under said ating at one end of the body portion, a pivoted handle mounted on the body portion, a pin magazine within the body portion for holding a pin tape, a rotatable vertical barrel having longitudinal peripheral grooves located at one end of the hammer, said grooves accommodating pins held within the pin tape positioned within the magazine, means for rotating with each under the hammer, including a lever operated by the handle, said lever moving the hammer upwardly against the tension of the spring, andja sliding member within the body portion operated by said lever, the sliding member engaging within the grooves rotating the barrel moving a pin directly under the hammer for driving by said hammer.
