SPECIFICATION forming part of Letters Patent No. 660,705, dated October so, 1900.
Application filed ()c'tohr 27, 1899. Serial No. 7345936. (No model.)
T0 at whom it may concern:
Be it known that I, HENRY JAMES KIMMAN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Portable Pneumatic Tools, of which the following is a specification.
The invention relates principally to that class of portable pneumatic tools known as riveting-machines, in which there is a holder provided with clamping mechanism for holding the tool in place and a direct-acting engine to operate upon the heading-tool, all of which will more fully hereinafter appear.
The principal object of the invention is to provide a simple, economical, and efficient portable pneumatic tool adapted to head rivets in the construction of machinery and buildings; and the invention consists in the features, combinations, and details of construct-ion hereinafter described and claimed.
Figure 1 is an elevation of a tool constructed in accordance with my improvements, shown partly in section; Fig. 2, a detail View of a portion of the clamping mechanism; and Fig. 3, an enlarged sectional detail of the main throttle-valve, hereinafter more fully described.
In the art of heading rivets in boiler-making or other constructions it is well known that the usual way to head such rivets is to do the principal part of the operations by handthat is, one operator is supposed to hold a heavy counterweight against the head of the rivet while another operator uses a heading-tool and sledge or heavy hammer to head the other end of the rivet. This method of heading rivets is not only laborious, but takes up a great deal of time and involves considerable expense. It is highly desirable, therefore, in order to economize both time and expense, to provide a machine or tool which can clamp the tool firmly in place against the rivet, or both ends thereof, while a reciprocating hammer is moved with great rapidity so as to contact the heading-tool and quickly head the rivet. To attain this result is the principal object of my invention.
In constructing a tool in accordance with my improvements I provide a bifurcated or C-shaped frame portion A of the desired size and strength to hold the operative and other parts in position. One end of this frame por tion is provided with a fluid-pressure chain: ber B, having a reciprocating plunger B movably mounted therein, so that a motive fluid may be used to move the plunger up ward and against the headed end of a rivet. This plunger, with its motive fluid, acts in a dual capacity-first as a clamp and second as a counterweightas will more fully hereinafter appear. The other end of the C- shaped frame is provided with a clamp portion 0, split at c and provided with a clamping-bolt O. In the cylindrical opening 0 of this clamp portion I insert a pneumatic hammer D of any of the usual forms of construction, which is provided at its front end with a heading-tool d, adapted to contact the other end of the rivet. This pneumatic hammer D, as above suggested, may be of any of the usual forms of construction-that is,the usual form which is provided with a fluid-pressure cylinder having a reciprocating piston-hammer in the interior thereof adapted to be operated or reciprocated by a motive fluid such as compressed air and during its reciproca tions to contact the heading-tool and operate it so as to effectually and efficiently head a heated rivet.
To provide means by which the clamping plunger B may be operated, a pipe or tube E is provided, connected with a passage 6 in the frame portion, which in turn connects with the fluid-chamber at or near its rear end and behind the head of the' plunger, so thatwhen fluid under pressure is admitted to this chamber the plunger is moved forward against the tension of a helical spring b. When the supply of motive fluid is shut off, this helical spring 1) acts to return the clamping-plunger to its normal position'and out of engagement with the rivet.
It is highly desirable that a main supply or throttle valve be provided, in combination with other mechanisms, by which asupply of motive fluid may be furnished simultaneously to the clamping-plunger and the pneumatic hammer and enable the operator to use one hand for the purpose of guiding the tool in position and the other hand for the purpose of operating the pneumatic hammer. In order to accomplish this result, the frame portion is provided with a main inlet-chamber I G, which is connected with the inlet g, and
which in turn may be connected in any suitable manner with the source of motive fluid, such as compressed air. Arranged in this inlet is a main throttle-valve H, which is normally held in its seat by means of a helical spring h. (Shown particularly in Fig. 3.) A throttle-lever H is provided and pivotally secured at h to the handle portion in the desired position, so that it may contact a loose pin h which in turn contacts the main throttle-valve and is held in contact against the throttle-valve by meansof the helical spring h, which operates the main throttle-valve in one direction.
In operation the main throttle lever is pressed inwardly against the handle, which action opensthe main throttle-valve and admits a supply of motive fluid to the inletchamberG. This main inlet-chamber is con nected with the fluid-pressure chamber of the clamping-plunger by means of the pipe E, above described, and is also connected with the pressure-chamber of the pneumatic hammer by means of the pipe I, as shown particularly in Fig. l, which being of the usual construction and provided with its own throttle-valve and throttle-lever 2' (shown in Fig. 1 of the drawings) enables the operator to use one hand for operating the main throttle and guiding the tool and the other for controlling the hammer.
In operating the tool as a single machine for the purpose of riveting, the toolis grasped,
in the usual manner by passing the fingers of the hand through the opening H so that the operator can guide it to bring the clamping-plunger to one end ofthe rivet--namely,
the headed portionand the heading-tool of the pneumatic hammer opposite the unfinished end. The main throttle-valve is then operated, which admits a supply of fluid underpressure into the clamping-plunger pressure-chamber, which action forces the plunger outwardly and clamps both ends of the rivet between such plunger and the headingtool. The operator can then use his other hand to open the throttle-valve of the pneumatic hammer as and when he desires. The action of the pneumatic hammer therefore can be used efficiently and quicklyto head the unfinished end of the rivet.
One of the principal advantages obtained by the use of a tool provided with my improvements is that any size of pneumatic hammer can be used in connection with the tool. For instance, in small boilers or tanks small rivets only are used. Consequently it is desirable to use a tool capable of delivering a great number of light strokes per minute. In large structures, however, large rivets are used, and asaconsequence it is desirable to use a heavy operating-hammer, all of which can be obtained by the use of my improvements.
I claim 1. In a tool of the class described, the combination of a bifurcated frame portion provided at one end with a movable clampingplunger to contact the head of a rivet and the other end with means to receive and removably hold a portable pneumatic hammer, sub stantially as described.
2. In a tool of the class described, the combination of a bifurcated frame portion provided at one end with a movable clampingplunger adapted .to contactone end of a rivet and at the other end with a clamping portion adapted to receive a pneumatic hammer, substantially as described.
3. In a tool of the class described, the combination of a bifurcated frame portion pro vided at one end with a pressure-chamber having a movable clamping-plunger therein to contact the head of a rivet and at the other end with a pneumatic hammer and a main supply-chamber adapted to contain a supply of motive fluid and connected with the clam ping-plunger chamber and with the pneumatic hammer, and a main throttle-valve in the inlet of such main supply-chamber adapted to open and close the inlet of such supply-chamber, substantially as described.
4. In a tool ofv the class described, a substantially C--shaped frame portion provided at one end with a pressure-chamber having a clamping counter-balancing reciprocating plunger therein and at the other end with a clamp adapted to removably hold a portable pneumatic hammer, a main inlet-chamber G connected with the pressure-chamber of the heading-plunger and arranged to be connected with the portable pneumatic harnmeigand a main throttle-valve to control the supply of motive fluid to such inlet-chamber, substantially as described.
