RIVETING MA'CHILNE VOR HAMMER.
SPECIFICATION forming part of Letters Patent No. 466,476, dated January 5, 1892. Application tiled July 20,1889. Serial No. 318,174. (No model.)
To aZZ whom it may concern:
Be it known that I, WILLIAM R. WEBSTER, of the city and county of Philadelphia, State of Pennsylvania, have invented a new and usefulRiveting Machine or Hammer, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.
- My invention relates to the construction of the riveting-machines in which the riveting is accomplished by repeated rapid blows of a steam or compressed-air hammer.
The object of my invention is to provide a riveter which shall be free from the objections Vfound to those machines in which the hammer-piston acts directly upon the rivet, and generally to improve the construction of riveting-machines of the above description. n
The novel features of'my invention will be best understood. after a descripton'ot' the drawings in which it is illustrated, and they will be hereinafter speciically pointed out in the claims, reference being now had to the drawings which illustrate my invention, and` y in which- Figure l is a longitudinal cross -section through my improved riveter; Figs. 2 to 7, inclusive, views of an improved valve used in connection with my apparatus in the way hereinafter described.
A is a casing, in which are formed a cylinder A for the hammer-piston and a larger cylinder A2 for the clamping or holding piston.
B is the ham mer-piston, and B the hammer connected with said piston.
C is the clamping or holding piston, which .I prefer to make with a large steam-surface etingtool D, entirely unconnected with the hammer B', is adjusted in the lower portion ofthe opening C2, as shown. Passages cs c3 are formed in the lower part of the clampingcylinder, so as to permit the escape of air from the opening C2.
The riveting-tool B may be of any convenient construction, having its end CZ formed so as to properly grip the end of the rivet and its upper end made smaller than the opening C?, in which it is secured, a ring of Babbitt metal or any other convenient packing N being provided to hold the riveting-tool properly centered in the clamping-cylinder. As shown in the drawings, the clamping-cylinder acts directly on the riveting-tool D, pushing it against the end of the rivet. A spring M is shown extending from the clamping-cylinder around the riveting-tool and forming a'clip to hold the plates H together; or, if desired, any of the usual constructions by which the clamping-cylinder acts upon the plate may be substituted, this part of the apparatus forming no feature of my invention, yand it being immaterial to the said invention whether the clamping-cylinder acts onl the riveting-tool alone, on the plates alone, or on both together, as shown. l
G is the rivet, the head of which rests in a hollow f of the anvil F', which anvil is, as shown, connected with the head of the casing A by means of an arm F, the arrangement shown being a convenient one for a portable riveter.
't t" are steam-ports leading to the two ends of the hammer-cylinder from the actuatingvalve I, steam beingled into the valve-charn- ,p
ber through the port 7a2.
K indicates the main supply-passage for the steam. From this passage a port la leads beneath the small steam-surface c4 ot'V the clamping-cylinder and another port 7c leads 'to the distributing-valve cock L, from the seat of which extends the port k2 to k3 and the exhaust-port 7a4, the port 104 being, as shown in Figs. 2 to 7, on a lower level than the ports k, k3, and k2, all of which are formed in the same plane. The cock-valve L is formed with passages or ports Z and Z, the passage Z being deeper than the passage L, so as to connect with the ports 104 when turned into the position shown in Figs. 2 and 3,
IOO
which figures represent the position of the cock-valve when turned so as to connect the ports 7c3 and k2 with the exhaust-port 7a4 and closes the supply-port 7s.
Figs. 4 and 5 represent the position of the cock-valve when it is turned so as to connect the supply-passage 7c with the passage k3, leading to the large steam-surfaces c', and closes the ports 7a2 and 7a3, and Figs. 6 and 7 represent the position of the cock-valve when turned so as to connect the supply-port 7c with the passages k3 and 7a2, so as to aetuate the hammer-piston, while at the same ti meholding the clamping-cylinder down by the pressure on its large steam-surface c'.
The operation of myimproved riveter is as follows: ln the irst place, steam being always admit-ted through the supply-passage 7c and the passage k to the small steam-surface cl of the clamping-cylinder C, there is always a pressure on said surface c4 tending to elevate the clamping-cylinder. Plates Il and rivet G beingarranged in position to be operated upon, the cock L is turned into the position indicated in Figs. 4 and 5, admitting steam through port k3 to the large steam-surface c', and causing the clamping-cylinder to move down, so as to clamp the plates and bring the rivetingtool B in contact with the end of the rivet, or one or both of these operations, as before noted. The cock-valve is then turned into the position shown in Figs. 6 and 7, in which position the steam is still admitted through ports 7.13, but also allowed to passinto the port 7a2, and thence to the valve-chamber, from which, by means of the valve l, it is made to actuate the hammer-piston B, the hammer B acting on the end of the supported riveting-tool l5, which always rests in contact with the end of the rivet. I have found that by using this su pported riveting-tool the tendency to bend or act unevenly upon the rivet is overcome, and much more effective and regular riveting can be accomplished than in cases where the hammer acts directly on the end of the rivet. When the riveting is accomplished,'
the cock-valve L is turned to the position ica/ive shown in Figs. 2 and 3 in the drawings, closing the supply-port and allowing the steam to escape to ports 7c3 and k2 to the exhaust 7a4. The small steam-surface c4 being then no longer eounteracted, the clamping cylinder moves upward and the apparatus is ready for the adj ustment of a new rivet.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a riveting-machine, the combination of a hammer cylinder and piston, a clampingeylinder, a riveting-tool unconnected with the hammer-piston and having bearings in the elampingcylinder, and a casing connecting the ham mer-cylinder and the bearings for the clamping-cylindel,so as to insure the alignment of the parts, all substantially as and for the purpose specified.
2. In a riveting-machine, the combination of the casingA, containing a clamping-piston C and hammer-piston B, the clamping-piston being arranged within the cylinder ol the hammer-piston and having the large and small steam-surfaces c c, substantially as and for l the purpose specified.
In a riveting-machine, the combination i of a casing A, containing a clamping-piston` C and hammer -piston B, said clamping-piston having a steam-surface c4 exposed to the pose specified.
4. In a rivetlng-machine, the combination of a casing A, containing a clamping-piston C, having a steam-surface c and a hammerpiston B, a valvel for actuating the hammerpiston, ports 7c, 7a2, k, and 701, meeting in a cock-seat, said ports k and 7a4 being on dillerent levels and ports k3 7a2 0n the same level, and a cock-valve L, having ports ZZ', said port Z being deeper than port l, all substantially as and for the purpose specified.
