nrvnrmc AND cnmrrne MACHINE.
- Tocll whom it may concern:
Be it known that I, CLARK J. SMITH, re siding atOttumwa, in the county of Wapello and State of Iowa, have invented a 'new and. Improved Riveting and Calking Machine, of which the following is a specification.
My invention is an improved machine that is particularly designed for use in riveting and calking boiler plates and the like, and which generically includes a supporting frame composed of an arm that may be "projected into the boiler and carries an anvil die and its holder; a second armthat is connected to the, first arm to lie parallel thereto, the second arm carrying a retaining hammer casing of frusto-conical form to, which the riveting hammer en ine projects, a clamp provided for holding the ing the rivetupsetting operation, -which clamp may be moved to release the engine *so it may be given a gyratory movement in the casing to cause the rivet set or die to be griven to eflect a tight calking of the rivet ead. In its more subordinate nature, the in- .vention includes those novel details of construction, combination and arrangement of imparts, all of which will be first fully described, then be specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:
Figure 1, is a perspective view of my invention.v Fig. 2, is an enlarged central vertical longitudinal section of the same in use, parts being broken'away. Fig. 3, is a similar view, the clamp being released and the hammer engine being swung away to its calking position. Fig. 1, is a top plan view of the machine, the parts being shown in the position shown in Fig. 2. Fig. '5', is a view similar to Fig. 4, the parts being in the position shown in Fig. 3. Fig, 6, is a detail perspective view ofthe retainer that holds the rivet set-or die in place on the engine. Fig. 7, is a detail sectiontshowing one of the pivots for the clamping device.
Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the figures, 11 designates a pair of plates which are bolted together by two sets of bolts 2 and between which the lower and upper pipes 3-.4 respectively are clamped.
Specification of Letters Patent.
. Applioation-filedOctobcr 19, 1940.-- Serial Il'o. 587,888.
engine centrally in the retaining casing dur-.
5 designates a tubular casing \i'w in which a block 9 is mounted for longitudinal movement under. the influence of pneumatic pressure, or its equivalent, the casing'or cup 5 having an extension 6 to enter one end of the pipe 3 and it is riveted .to' such pipe by rivets 7 as'shown in the drawings.
8 designates the inlet to the cup 5' through which the working agent that forces the block upwardly, is admitted.
The block 9 forms a die holder and is apertured at 10 to receive the'shank of the die 11 whose head is cupped at 12 to conform to the'contour of the head of the rivet R which joins the plates of the boiler-B.
13 designates a retaining hammer casing of frusto-conical form, the end of lesser diameter being at the bottom and provided with .a concaved seat 16. The casing 13- also has a tubular-extension 14 to enter the pipe 4 towhich it is pinned at15, asindica-ted. .The casing 13 at its upper end has a bracketlike extension 17 to receive the pivot bolts Patented Sept. 12, 1911.
18 on which the clamp sections 19 are mounted.
The clamp which serves to retain the engine 24 in its central position during the upsetting action on the rivet, is composed of a pair of half clamp members 19 each having a body 20 apertured to receive the pivots 18, the body 20 where the pivots 18 pass through being rounded and provided with toothed portions 21 to intermesh with one another so that the movement of one of the sections 19by its handle extension 22 will effect a similar movement in the other section 19 to open or close the clamping device according as the handle 22 is movedin one direction, or the other.
The clamping device has its portion 19 upwardly projected and provided with a coniform seat 23 that cooperates with the correspondingly formed shoulder 35 of the hammer engine casing. 7
The hammer engine 24 may be of any approved construction, preferably, however, that shown in the drawings, and the easing of the engine is provided at its lower end with a spherical'segment 25 that engages the concaved seat 16, the curvature of the seat 16 and the corresponding face of the segment 25 being struck from the center of curvature R of the upset head of the rivet R, or in other words, being curved on the same center as is the cup 33 of the die 30 that forms said rivet head. The casing of the hammer engine is also provided at its lower end with an extension'26 having an annular groove 27 to receive the upper fingers of the gripper 28 whose lower fingers 29 enter the groove 31 on the head of the die 30. The die 30 has a shank 32 to project into the engine 24 and be impacted by its hammer piston, as clearly shown in the drawings, and as is usual in the art. The die 30 has its end face surrounding the cup portion 33, of coniform or beveled formation as at 34 for a purpose'hereinafter more clearly understood.
The engine casing 24 is adapted to swing on the center R when the clamp 19 is released to lie in engagement with the inner wall of the casing 13, as shown in Fig. 3 of the drawings, so that the casing maybe rotated on the center Bf in agyratory manner to eflect the 'calking action, as will be better understoodlater. The casing 24 is adapted to be moved by a handle 36 secured in itsupper end.
The device is adapted to be suspended from an overhead crane, not shown, through the medium of an adjustable clamp 37 on the pipe 4, the clamp 37 being shift-able along the pipe to the center of balance of the device as a whole, so as to maintain the pipes 3-4 as nearly horizontal'as practicable. a
The working agent, which may be compressed air, steam or other suitable motive fluid, is admitted to the engine 24 through a feed pipe 38, as clearly shown in the drawings.
Inoperation the pipe 3 with its carried parts is projected into the boiler to engage the head of the rivet R, as shown in Fig. 2, while the die 30 is brought into engagement with the end of the rivet R to be upset, it being understood that the plunger block 9 permits bringing the parts in position, and it is itself held in place by the working agent that enters through the pipe 39.
The clamp sections 19 are closed onto the casing 24 and when working agentis admitted to-the pipe 38 the hammer 40 is set into reciprocation in the usual manner to impact the'fdie member 30 and cause it to upset the end of the rivet R until the parts assume the position shown in Fig. 2 of the drawings, after which the clamp 19 is released, the casing 24 is turned until it lies in contact with the "inner wall of the casing after which a rotary motion is imparted to the engine 24 while it lies in contact with the casing 13, as shown in Fig. 3 of the drawings, thereby calking the rivet and insuring a tight joint.
From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will bereadily understood by those skilled in the art to which the invention appertains.
