To all whom it me concern:
Be it known that I, ARTHUR J. MCQUAIDE, of Canton, Stark county, Ohio, have invented a new, and useful Button-Set for Pneumatic Hammers, of which the following isa full, clear, and exact description, reference being had to the accom anying drawings,
forming part of this spec cation, in which- Figure 1 is a side elevation of the lower portion of a pneumatic hammer, showing one embodiment of my improved button set par tially in section; attac ed thereto; Fig. 2 is a similar view showing the end of the neumatic hammer in section and slight y inclined. Y
My invention has relation to a two piece button set, and is designed to provide a sim- 'ple, cheap, durable and eflicient set, which can be properly tempered to meet the requirements of a tool 0 this character.
The precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that changes may be made in the details of construction, and general form, without departing from my invention as described inthe specification, and illustrated in the drawings. In the drawings, the numeral 2 designates the lower portion of the cylinder of a pneumatic or any fluid actuated hammer, 3 1s theend of the piston or an intermediate striking piece interposed between the piston and the tool to be struck. Inserted into the end of the cylinder 2 and capable of movement therein is a stem 4 the lower end of which is reduced in diameter as shown at 5 and is rovided with the convex end 6, this stem orming one portion of myim roved button set the other portion being ibrmed by the member 7 having an orifice '8 with a concaved bottom 9 of substantially; the same radius as the radius of the converted end-of the stem 4. As will be seen by reference to the drawings the diameter of the orifice 8 is greater than the diameter of the end 5 of. the stem 4 in order to incline the hammer and the stem 4 and still retain the proper contact between the members 4 and 7. The member 7- is also provided with an annular boss orshoulder 10 at the upper end thereof, and
from the hammer when raised from the work. The lower end of the member 7 is provided with a concavity 12 of the proper size and she to form the rivet head.
\ he advantages of my invention result from a two piece button set or tool,-in which. each member can be tempered to meet the requirements of the work to which it is subjected. In the one piece button set the shank and the riveting end must be tempered to-the proper degree of hardness to meet the requirements for riveting, which temper is too hard for the shank or striking and of the tool which would spall under the continuous blows of the hammer. This is overcome by first tempering the tool to the required hardness and then drawing the satisfactory as it requires great skill to sufficiently reduce the hardness of the shank without drawing the temper from the workmg end of the tool. v Another objection to the one piece set isthe danger of cracking at the junction of the shank and the head of the tool which is caused b the unequal strain set up by the unequal odies of metal when plunged into the cooling bath. Also the cost of the tool, if made of a high grade of steel due to the amount of material required for each tool. With-my two iece set all of these objections are overcome y making the shank of a lower grade of steel and tempermg it to meet its requirements and makin the head of a high grade of steel and givin it. its required temper. The difference in t e diameter of the endof the shank and the opening in the head insures a proper contact between the end of the shank and the button set, and it also allows a canting of the hammer and shank with relation to the set without destroying their contact. The retaining springs in combination with the looseness between the shank and the head provide a means for readily applyin a new button set to the hammer, an 1t a so materially reduces the cost as the shank-can be used for any number of button sets or tools to be operated by' a fluid actuated hammer.
I claim: f I
1. A tool for fluid actuated hammers comprising a tool end havingan opening with a concaved bottom, and a shan of lessarea than the opening and havi a convexed head to seat in said bottom 0 the opening; substantially asdescribed. 2. A tool for fluid actuated'hammers comprising a tool end having a circular opening, with a concaved bottom, and a shank of smaller diameter than the opening and having a conveXed head to seat in said bottom of the opening; substantially 'as described.
3. A tool for fluid acfiiated hammers comprising a tool end havm'g an 0 ening with a. concaved bottom, a shank of ess area than the opening and having a convexed head to seat in said bottom of the openin and means to retain the tool on the end oft e hammer; substantially as described.
4. A button or rivet set for fiuidaetuate'dhammers, formed in two pieces a stem or my hand.
