- T 0 all "whom it may concern Be it known that we, FRANK B. KEGK and Hnxnr A. LUDwrc, citizens of the United States, residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Riveting- Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.
- Our invention relates to riveting machines, its object being to provide a riveting machine economical of manufacture and efiicient in its operation.
- the illustrated embodiment of our invention comprises a machine specifically adapted to rivet the ends of tubular members such as the inner sleeves of commutators, the abutment members shown being arranged so as to properly receive and operate upon a commutator of standard construction.
- Figure 1 represents a front elevation of a riveting machine embodying our invention, a portion of the abutment member being shown in vertical section, and a commutator constituting the work upon which the riveting operation is being performed being also shown in axial section therein.
- Fig. 2 represents a view similar to that shown in Fig. 1, showing the parts in the position which they occupy while the machine is not in operation.
- Fig. 3 represents a side elevation of the machine showing the parts in the same position in which they are shown in Fig. 2.
- Fig. 4. represents, upon an enlarged scale, an axial section of a commutator showing the parts assembled and in the condition in which they are found prior to the riveting operation.
- Fig. 5 represents a view similar to that of. Fig. 4 showing the parts after the riveting operation is completed.
- Fig. 6 represents a horizontal section taken upon the plane indicated by line IV-IV in Fig. 1,
- the illustrated embodiment ofour invention comprises a base 1 to which are secured three vertical standards, two lateral standards 2, 2, and a rear standard 3. These standards are all parallel with each other, as shown, and with the base constitute the main frame of the machine.
- the upper end of standard 3 is threaded as at 4: and secured thereto by means of nuts 5, 5, is an abutment member 6.
- the said standards 2, 2 have their upper ends threaded which engage the threaded openings 7, 7 of the member 6, and extend upwardly beyond same a short distance, as shown in Fig. 1. Nuts 8, 8, lock this abutment member in position.
- each of which is provided with an upwardly extending cylindrical portion 10, integral with the lower or threaded portion.
- These two portions 10 are threaded at their upper ends at 11.
- Upon the upper or threaded ends 11 of the members 10 are the nuts 15, 15, respectively, and intermediately of each nut and the crosshead 1 is a coil spring 16,'Fig. 1.
- This cross head has secured to it in any suitable manner a pneumatically operated hammer 17 of standard construction, the axis of the hammer being placed vertically, as shown.
- This hammer is provided with the usual controlling member 18 forming part of a controlling valve mechanism for controlling the operation of the hammer, as will be readily understood.
- a cylinder 22 Suitably secured to the frame and having its vertical axis in alinement with the axis of the hammer 17, is a cylinder 22 provided with a suitable piston (not shown) and a piston rod 23.
- the upper end of this piston rod is formed with a teat 2st of an exterior diameter equal to the interior diameter of the sleeve 25 of the commutator, so that the said sleeve may be received by and held against lateral displacement upon the upper end of said piston rod.
- This piston rod therefore acts as a work-holder.
- a guidemember 26 consisting of a suitable plate is provided with apertures 27 through which the side rods 2, 2, and rear rod 3, extend, suitable set screws 28, 28, being provided to secure this guiding-member in place.
- the center of the guidingplate is formed with a suitable bore 29, through which the piston rod 23 extends.
- A. pipe 30 is connected with a suitable source of compressed air supply (not shown) and has its upper end connected with a fourway valve 31.
- This valve is connected with a pipe 32 which in turn is connected with the upper end of the interior of cylinder 22 and hence above the piston.
- Another pipe 33 connects said valve with the lower end of the cylinder and below the piston.
- a third pipe at is connected with the valve and acts as an exhaust pipe.
- a. cylindrical vertical opening 36 formed in the abutment member 6. Passing and projecting through this opening is a riveting tool 37 having its upper end formed with a flange 38 which rests upon the upper surface of an upwardly projecting boss 39 forming part of the said abutment member, when the parts are in their inoperative position, shown in Fig. 2.
- the lower end of this tool is formed with a teat -10 adapted to enter the upper end of the sleeve 25 of the commutator and forming a rounded concave shoulder 41 which constitutes the riveting surface of the tool.
- Surrounding the lower end of the opening 36 is an annular groove 42, Figs. 1 and 2, which is adapted to receive the upper end of the commutator and forms an annular shoulder 43 which is adapted to abut the commutator laterally of the upper end of the sleeve, as shown in Fig. 1.
- the guide-member 26 is placed in a position such that when the piston is in its lowermost position in the cylinder 22, the upper or workholding end of the piston rod 23 will project some distance above said member 26, as shown in Fig. 2.
- the parts of the commutator are assembled as shown in Fig. i, said parts including the inner sleeve 25 which is provided with the lower flange 25, it being desired now to rivet the upper end of said sleeve so as to secure same permanently in place, as will be readily understood.
- the commutator parts so assembled are now placed upon the upper end of the piston rod or work-holder 23, when the latter is in its lowered position, as shown in Fig. 2, and the handle 31 of the valve 31 turned so as to admit pressure below the piston in the cylinder 22, at the same time admitting, as previously de scribed, the compressed air into the pipe 35.
- the riveting tool 37 follows the commutator until the head 38 is again in contact with the upper surface of boss 39, the hammer 17 and cross-head 14; likewise moving downwardly.
- This causes the controlling valve lever 18 to assume its normal position and cut ofi the supply of air from the hammer, the latter thereby ceasing its operation. WVhen the piston rod reaches its lowermost position, the commutator is re moved, and the above-described operation may then be repeated.
- the abovedescribed device comprises an efficiently operating riveting mechanism in which the valve 31 and the valve controlled by the lever 18 together form means for controlling both the riveting hammer and the movement of the work-holder toward the abutment member, the valve 31 controlling the supply of air pressure to both the hammer and the cylinder 22, the valve mechanism of which the handle 18 forms a part controlling, however, the operation of the hammer alone.
- the means for controlling the operation of the riveting hammer is itself controlled by the yielding movement of the latter, in opposition to the springs 16, the work-support imparting the yielding movement to the hammer.
- a riveting machine the combination of a suitable frame; an abutment-member fixed to and adjustable upon the latter; a work-support relatively movable toward and fro-m said abutment-member; a riveting device mounted upon said frame and cooperating with said work-support; means for operating said riveting device; means for effecting the relative movement of said work-support and abutment-member; and
- a suitable frame a stationary abutment member mounted upon the latter; a worksupport relatively movable toward and from said abutment member; a riveting device cooperating with said work-support and yieldingly mounted upon said frame; means for controlling the said relative movement; and means for controlling the operation of said riveting means and itself controlled by the yielding movement of the latter.

BIVETING-MACHINE.
Specification of Letters Patent. Patented Sept. 12, 1916.
Application filed July 27, 1915. Serial No. 42,200.
T 0 all "whom it may concern Be it known that we, FRANK B. KEGK and Hnxnr A. LUDwrc, citizens of the United States, residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Riveting- Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.
Our invention relates to riveting machines, its object being to provide a riveting machine economical of manufacture and efiicient in its operation.
The said invention consists of means hereinafter fully described and particularly set forth in the claims.
The annexed drawings and the following description, set forth in detail certain means embodying our invention, the disclosed means, however, constituting but one of va rious mechanical forms in which the principle of the invention may be applied.
The illustrated embodiment of our invention comprises a machine specifically adapted to rivet the ends of tubular members such as the inner sleeves of commutators, the abutment members shown being arranged so as to properly receive and operate upon a commutator of standard construction.
In said annexed drawings :Figure 1 represents a front elevation of a riveting machine embodying our invention, a portion of the abutment member being shown in vertical section, and a commutator constituting the work upon which the riveting operation is being performed being also shown in axial section therein. Fig. 2 represents a view similar to that shown in Fig. 1, showing the parts in the position which they occupy while the machine is not in operation. Fig. 3 represents a side elevation of the machine showing the parts in the same position in which they are shown in Fig. 2. Fig. 4. represents, upon an enlarged scale, an axial section of a commutator showing the parts assembled and in the condition in which they are found prior to the riveting operation. Fig. 5 represents a view similar to that of. Fig. 4 showing the parts after the riveting operation is completed. Fig. 6 represents a horizontal section taken upon the plane indicated by line IV-IV in Fig. 1,
The illustrated embodiment ofour invention comprises a base 1 to which are secured three vertical standards, two lateral standards 2, 2, and a rear standard 3. These standards are all parallel with each other, as shown, and with the base constitute the main frame of the machine. The upper end of standard 3 is threaded as at 4: and secured thereto by means of nuts 5, 5, is an abutment member 6. The said standards 2, 2, have their upper ends threaded which engage the threaded openings 7, 7 of the member 6, and extend upwardly beyond same a short distance, as shown in Fig. 1. Nuts 8, 8, lock this abutment member in position.
Secured on to the upper ends of-the standards 2, respectively, are two members 9, 9,
each of which is provided with an upwardly extending cylindrical portion 10, integral with the lower or threaded portion. These two portions 10 are threaded at their upper ends at 11. Resting upon the shoulder 12 formed upon the members 9, respectively, are two loose tubes 13, 13, and resting upon the upper ends of these-tubes is a crosshead 14, through suitable openings in which the portions 10, 10, of members 9 extend. Upon the upper or threaded ends 11 of the members 10 are the nuts 15, 15, respectively, and intermediately of each nut and the crosshead 1 is a coil spring 16,'Fig. 1. This cross head has secured to it in any suitable manner a pneumatically operated hammer 17 of standard construction, the axis of the hammer being placed vertically, as shown. This hammer is provided with the usual controlling member 18 forming part of a controlling valve mechanism for controlling the operation of the hammer, as will be readily understood.
It will be seen from the above construction that normally the cross-head 14: rests upon the upper ends of the tubes 13 and that by means of a force suitably applied from below, the, cross-head and hammer carried thereby may be caused to yield upwardly, thereby giving the controlling valve lever 18 a yielding movement in such upward direction, in addition to the yielding movement which it possesses in its direct actuation, as will be readily understood.
Secured in any suitable manner, so as to be fixed with relation to the frame, is an. upwardly projecting strap 19, Figs. 1 and 3. This strap is shown secured to the upper surface of the abutment member 6, and extends upwardly beyond the lever 18 of the hammer, its extreme upper portion 20 being provided with an adjustable screw member 21, the lower end of which lies in the path of yielding movement of the said lever, when such movement is imparted to the hammer and said lever, as will be hereinafter described.
Suitably secured to the frame and having its vertical axis in alinement with the axis of the hammer 17, is a cylinder 22 provided with a suitable piston (not shown) and a piston rod 23. The upper end of this piston rod is formed with a teat 2st of an exterior diameter equal to the interior diameter of the sleeve 25 of the commutator, so that the said sleeve may be received by and held against lateral displacement upon the upper end of said piston rod. This piston rod therefore acts as a work-holder.
A guidemember 26 consisting of a suitable plate is provided with apertures 27 through which the side rods 2, 2, and rear rod 3, extend, suitable set screws 28, 28, being provided to secure this guiding-member in place. The center of the guidingplate is formed with a suitable bore 29, through which the piston rod 23 extends.
A. pipe 30 is connected with a suitable source of compressed air supply (not shown) and has its upper end connected with a fourway valve 31. This valve is connected with a pipe 32 which in turn is connected with the upper end of the interior of cylinder 22 and hence above the piston. Another pipe 33 connects said valve with the lower end of the cylinder and below the piston. A third pipe at is connected with the valve and acts as an exhaust pipe. This valve construction is old and well-known and constitutes no part of our invention. By turning the valve into the position shown in Fig. 6, compressed air is admitted above the piston in the cylinder and if such piston is in its elevated position, will cause it to move downwardly and the upper end of the piston rod 23 or work-holder, to recede from the abutment member 6. At the same time any air below the piston will be expelled through the valve and out through the exhaust pipe 34, as will be readily understood. By throwing the valve into the position shown in dotted lines in Fig. 6, the piston and work-holder may be elevated, as will be also readily understood. Connected with the pipe 33 is a flexible pipe 35 which is connected with the pneumatic hammer 17 at 36, in the usual manner, to supply the necessary fluid pressure to such hammer. It will therefore be seen that when the valve 31 is turned to supply pressure to the pipe 33, similar pressure will be supplied to the pipe 35 and hence to the hammer.
Co-axial with the piston rod 23 and hammer 17, is a. cylindrical vertical opening 36, formed in the abutment member 6. Passing and projecting through this opening is a riveting tool 37 having its upper end formed with a flange 38 which rests upon the upper surface of an upwardly projecting boss 39 forming part of the said abutment member, when the parts are in their inoperative position, shown in Fig. 2. The lower end of this tool is formed with a teat -10 adapted to enter the upper end of the sleeve 25 of the commutator and forming a rounded concave shoulder 41 which constitutes the riveting surface of the tool. Surrounding the lower end of the opening 36 is an annular groove 42, Figs. 1 and 2, which is adapted to receive the upper end of the commutator and forms an annular shoulder 43 which is adapted to abut the commutator laterally of the upper end of the sleeve, as shown in Fig. 1.
When the parts are in their normal or inoperative position, shown in Fig. 2, the lower end of the tool 37 projects some distance beyond the lower end of the shoulder 43, as shown in Fig. 2.
The guide-member 26 is placed in a position such that when the piston is in its lowermost position in the cylinder 22, the upper or workholding end of the piston rod 23 will project some distance above said member 26, as shown in Fig. 2.
The positions of the cross-head 1a and abutment member 7 are such that the lower end or head 4:4: of the hammer 17, will rest normally upon the upper end or head of the riveting tool 37. In this position, the lower end of the adjustable screw 21 is out of contact with the lever 18 of the controlling valve of the hammer.
We will now describe the operation of the above-described device.
The parts of the commutator are assembled as shown in Fig. i, said parts including the inner sleeve 25 which is provided with the lower flange 25, it being desired now to rivet the upper end of said sleeve so as to secure same permanently in place, as will be readily understood. The commutator parts so assembled are now placed upon the upper end of the piston rod or work-holder 23, when the latter is in its lowered position, as shown in Fig. 2, and the handle 31 of the valve 31 turned so as to admit pressure below the piston in the cylinder 22, at the same time admitting, as previously de scribed, the compressed air into the pipe 35. From this latter pipe the air may be admitted to the hammer so as to operate same, by the downward pressure of the lever 18 of the controlling valvethereof, as will be readily understood. lVhen the air is so admitted to cylinder 22, the piston rod 23 is carried upwardly, thus carrying the assembled parts of the commutator upwardly in a like manner. Such upward movement finally causes the upper end of the com mutator to engage the lower end of the riveting tool, the teat 40 entering the upper end of the bore of the sleeve 25. This upward movement continues .and the riveting tool 37 is raised, thus raising the hammer 17 and the cross-head 14 against the action of the springs 16. This upward movement continues until the shoulder 43 engages the surface 25 of the commutator, such surface being shown clearly in Fig. 4. The screw 21, however, is of a length such and is adjusted so that as soon as this engagement takes place, the lower end of said screw will have depressed the lever 18 so as to admit the pressure to the interior mechanism of the hammer and operate same. The hammer, therefore, delivers successive blows to the upper end of the loosely mounted riveting tool 37, and the riveting action takes place. This action is continued until the riveting operation is complete, whereupon the handle 31 is turned so as to admit pressure above the piston and permit the air below same to be exhausted. In the initial portion of the downward movement of the piston rod, the riveting tool 37 follows the commutator until the head 38 is again in contact with the upper surface of boss 39, the hammer 17 and cross-head 14; likewise moving downwardly. This causes the controlling valve lever 18 to assume its normal position and cut ofi the supply of air from the hammer, the latter thereby ceasing its operation. WVhen the piston rod reaches its lowermost position, the commutator is re moved, and the above-described operation may then be repeated.
It will therefore be seen that the abovedescribed device comprises an efficiently operating riveting mechanism in which the valve 31 and the valve controlled by the lever 18 together form means for controlling both the riveting hammer and the movement of the work-holder toward the abutment member, the valve 31 controlling the supply of air pressure to both the hammer and the cylinder 22, the valve mechanism of which the handle 18 forms a part controlling, however, the operation of the hammer alone. In this mechanism, the means for controlling the operation of the riveting hammer is itself controlled by the yielding movement of the latter, in opposition to the springs 16, the work-support imparting the yielding movement to the hammer.
Having fully described our invention, what we claim and desire to secure by Letters Patent is 1. In a riveting machine, the combination of a suitable frame; an abutment-member mounted upon the latter; a work-support relatively movable toward and from said abutment-member; a riveting device cooperating with said work-support; means for operating said riveting device; means for actuating said work-support; and means for controlling the operation of said riveting device and the actuation of said work-support.
