PUTTYING DEVICE.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed December 3, 1912. Serial No. 734,728.

To all whom it may concern Be it known that I, WILLIAM E. GLovnR, a citizen of the United States, residing at Maryville, in the county of Nodaway and State of Missouri, have invented new and useful Improvements in Puttying Devices, of which the following is a specification.

This invention is an improved put-tying device embodying a magazine to receive the putty, a nozzle forming a discharge for the magazine, a knife for applying the putty to the work and mean to force the putty from the magazine through the nozzle for manipulation by the knife so as to greatly facilitate and expedite the operation of put-- tying, as when glazing sash, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :F igure 1 is partly a side elevation and partly a longitudinal central sectional view of a puttying device constructed in accordance with my invention. Fig. 2 is a transverse sectional view of the same on the plane indi cated by the line aa of Fig. 4. Fig. 3 is a similar view on the plane indicated by the line b?) of Fig. 1. Fig. 1 is a plan of the same. Fig. 5 is a transverse sectional view on the plane indicated by the line 00 of Fig. 1.

The magazine 1 of my improved puttying device is tubular in form and is provided at its inner end with a closure block 2. A plunger 3 is arranged for operation in the magazine and has a rod 1 which extends through a central opening in the closure block and is provided with a series of notches 5 on one side. At the exposed end of the plunger rod is a button or knob 6. A coiled extensile spring 7 is arranged in the magazine, around the plunger rod and bears at one end against the closure block 2 and at the other end against the plunger, it being the office of this spring to move the plunger outwardly in the magazine, so as to eject putty from the latter. A casing 8, which is here shown as cylindrical, incloses the magazine and is provided in its ends with caps 91O through which the ends of the magazine extend. The casing is secured to the cap 10 by means of screws 11 certain of which also extend through one end of the magazine and enter the closure block and, hence, secure the latter in place in the inner end of the magazine. The cap 9 is secured to the outer end of the casing by screws 12 and i also secured to the inner end of a discharge nozzle 13, the latter being threaded to the cap as at 14. The outer end of the magazine enters the inner end of the nozzle at 15.

A plunger 16 is arranged to move in the casing and has a central openin through which the magazine extends. 1 pair of rods 17 are connected to the said plunger and operate in openings in the cap 10 and to the exposed ends of these rods is attached a handle at 18. A coiled extensile spring 19 which is stronger than the spring 7 is arranged in the casing 8 and around the magazine and bears at one end against the cap 10 and at the other end against the plunger 16. The handle member has guide openings through which the plunger rod 4 extends and on the handle member is a pivoted dog 20 which, by the action of a spring 21 may be caused to engage any one of the notches 5 of the plunger rod to lock the handle member and, hence, also the rods 17 and the plunger 16 to the rod of the plunger 3. I also provide a trip 22 which may be engaged with the dog to lock the latter in disengaged position, this trip being provided with a weak spring 23 which, when the dog lever is pressed against the tension of the spring 21, causes the trip to draw back to disengage the dog so that the spring 21 will then engage the dog with one of the notches 5 and thereby lock the handle member to the plunger rod 4.

hen the plunger rod is not engaged by the dog it is free to move longitudinally and independently of the spring pressed plunger 16 either against the tension of the spring 7 or by the action of said spring, in which latter event, the spring 7 will actuate the plunger 3 to cause the latter to force putty out of the magazine and through the discharge nozzle. When the dog 20 is engaged with one of the notches 5 of the plunger rod 4, the spring 19 as well as the spring 7 will exert their tension to force the plunger 3 outwardly so as to increase the pressure of the plunger 3 against the putty in the magazine and, hence, discharge the putty from the magazine through the nozzle at a more rapid rate and under a greater degree of compression than when the dog 20 is tripped and the plunger 3 is actuated solely by the spring 7. Hence, the degree of spring pressure on the ejecting plunger of the device may be varied at will. I also provide a bolt 2st to lock the plunger rod 4- and, hence, prevent movement of the plunger 3 in the magazine when this is desired. This locking bolt operates in an opening in one side of the closure block 2 and is provided with a guide yoke 25 the arms of which are slotted as at 26 and operate in guide grooves :27 in opposite sides of said closure block 2, screws 28 being employed to connect the arms of the guide yoke to the said block, the said screws operating in the slots 26. A spring 29 is arranged on the bolt 2%, one end of the said sgring bearing on the block 2 and the other end bearing against the inner side of the yoke, said spring acting to normally more the bolt out of engagement with the plunger rod t. When, however, the springs 7 and 19, or either of them, are under tension and the plunger 3 in withdrawn position, the bolt 241: may be engaged with a notch of the plunger rod l to lock the plunger 3 in such withdrawn position, the triction of the plunger rod against the bolt 2 L owing to the power of the springs 719 or either of them as the case may be, preventing the spring 29 from releasing said bolt 24-.

A putty knife blade 30 is arranged at one side of the discharge end of the nozzle 13 and is connected thereto by rings 81 formed with said knife or blade and through which the outer end of the nozzle extends.

W'hile I have herein shown and described a preferred form oi the invention, 1 would have it understood that changes may be made in the form, proportion and construction of the several parts without de parting from the spirit of the invention and within the scope of the appended claim.

I claim A puttying device comprising a magazine having a discharge nozzle, means including a primarily acting spring to force the putty from the magazine, a secondarily acting spring, and means to connect the secondarily acting spring also to the putty ejecting plunger to apply the power of the secondarily acting spring as well as that of the primarily acting spring, and a putty ejecting plunger.

In testimony whereof I :l'l'llX my signature in presence of two witnesses.
