JOHN WOD'IWABD, 0F LEETONIA, OHIO.
uvm-camine moor..
To alZ 'whom it may concern:
Be it known that I JOHN WooDwAnn, a citizen of the UnitedV tetes, and a resident of Leetonia, in the county of Columbiana and State of Ohio, have invented a new and Improved Rivet-CalkingTool, of which/the f ollowing is a full, clear, and exact description.
. The object of the invention is to provide a new and improved -rivet calking tool, which is simple and durable in construction, to permit a ready change in of the tool on different forms of rivet or boltheads, with 'a view to calk or tighten the rivetor bolt.
For the purpose mentloned, use is madeof a casing, calking hammers pivoted in the said casing, and guide arms on the casing for engagement with the sides of the rivet or bolt head.
A practical embodiment of the invention is re resented in the accompanying drawings orming a part of this speclfication, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is an edge view of the rivet calking tool, part being in section; Fig. 2 is a sectional side elevation of the same; Fig. 3 is a sectional plan view of the same on the line 3-3 of Fi 2; Fig. 4 is a perspective view of the i e sleeve and arms; Fig. 5 is a'. side elevation of the upper end of the casing with a modified form of cap, shown in section; Fi 6 is a side elevation of the rivet calking too in upside down position for use .When'calking or tightening overhead rivets or bolts; Fi 7 is a sectional plan view of a modified orm of the tool provided with three hammers; and Fig. 8 is a similar view of. another modified form of the tool provided with four hammers.
Thecasing A of the rivet calkin tool is preferably made tubular, and provi ed'near lts lower end with a slot A for the passage of calking hammers B, B, mounted to turn on bushings C held in the flattened sides B2 formin the terminals of the casing A. Bolts pass through the bushings C and the flattened sides A2 of the casing, to hold lthe bushings inA place. The hammer heads B of the calking hammers B, B project beyond the lower terminal of the casing A to engage the base of a rivet or bolt head E at diametrically opposite points, as will be readily understood by reference to Figs. 1

and 2. .The hammers B, B are provided with upwardly-extending tails B2 havingl their upper edges curved, as s'hown in Fig. 2, for engagement by the rounded-off head F of a piston F, extendin within the upper end of the casing A an mounted to slide in a cap G screwing in the upper threaded terminal As yof the casing A. The piston F is provided adjacent the head F with an enlarged portion F2 for stiening and increasirg the weight of the piston to .insure an e ective blow of the hammers on the rivet. or bolt head. Now by screwing the cap G out-ward or inward on the casing A the upper end of the piston projects more or less eyond the cap for receivin blow, by a motor or pneumatic hammer H. The cap G also serves as a rest for the motor or pneumatic hammer H to enable the operator to hold the alking tool firmlyv in lproper position on the work. The cap G 1s adapted to be locked in the adjusted position by suitable means, such, for instance, as springs G secured to the casing A and engaginglengthwise-extending slots G2 formed exteriorl on the cap G. If desired, the springs may be dispensed with and other means employed; for instance, the screw thread A4l on the upper end of the casing A may be made square, as shown in Fig. 5, for engagement with corresponding screw threads on the cap G. When the tool is used upside down for calking or tightening the heads of overhead rivets or bolts, as shown in l6, then use is preferably made of a spring I coiled around the piston F and resting with its lower end on the cap G and pressing with its upper end on the shoulder F2, so as to normally hold the piston F in its proper position to allow the motor or calking hammer to operate continuously.
In order to guide the hammer heads B relative to the rivet or bolt heads E. use is made of guide arms J located opposite each other Aand at right angles to the hammer heads B, and the said guide arms J depend from a sleeve J tit-ting exteriorly on the lower terminal A2 of the casing A. The bolts D previously mentioned engage the opposite sides of the sleeve J so as to securely hold the sleeve J in position on the terminal A2. In order to keep the hammer heads B normally in open position, use is made of K attached to theopposite sides of the sleeve J and pressing with their free ends on the tails B2 of the hammers B.
When it is desired 'to change the hammers B for use on different oforms df rlvets or, bolts, then it is only necessary to remove the bolts' D, sleeve J and bushings C forplacing a differentset of calking hammers 1n osition, together with a sleeve J having guide arms J corresponding to the new set of hammers tobe used. The parts `can then be readily replaced on the casing Aand the tool is ,ready for use on a diii'erent orniof rivet `or bolt head.
It is understood that for cone-head rivets, steeple head rivets and the heads of crown bolts and stay bolts, hammers B having d1fferently shaped hammer heads B are used, to correspond to the shape of the said heads, and consequently dierent forms of guide arms J are also necessary to bring the hammer heads B in proper position relative to the bases of the rivet or bolt heads.
It is understood that the guide arms J engage the sides of the bolt'or rivet head, while the hammer heads B act on the bases of the rivet orbolt heads, as will be readily understood by reference to Figs. 1 and 2.
The sleeve J carrying the arms J is preferably provided with elongated openings J 2 for the bolts D, so as to allow vertical adjustment of the sleeve J to pro erly adjust the guide arms J relative to the orm of rivet or bolt head to be acted on by the tool.
The rivet calking tool shown and described is very simple and durable in construction, and is composed of comparatively few parts, not liable easily to get out of order. y
As. shown in Figs. 2, 3 and 6 two calking hammers B are employed, but three or tour such hammers may be mounted on t-he casing A and actuated by a piston F, as will be readily understood by reference to Figs. 7 an 8. Having thus described my invention, l claim as new and desire to secure by Letters Pat-ent:
1. A rivet calking tool having a casing open at its lower end, calking hammers pivoted in the casing and projecting outwardly of the openend thereof, and guiding memhammers are out of contact with said bolt head.
2. A rivet calking tool, comprising a cas-4 ing having a slotted end, calking hammers extending in the slot of thesaid casing and having their heads end of the casing, olts extending transversely through the casing at the slotted end projecting beyond the for the said hammers'to turnon, guide arms rigidly attached to the slotted end of the casing by the said bolts and adapted to engage the rivet head whereby to prevent accidental displacement of the tool during its operation, and means for simult'aneously actuating the said calking hammers.
3. A. rivet calking tool, comprising a casing having a slotted end, calking hammers extendinglm the slot of the said casing and having t eir heads projecting beyond the end of the casing, bolts extending transversely through the casing at the slotted end for t-he said hammers to turn on, aguide comprising guide arms adapted to engage the head of a rivet, and a sleeve carrying the said guide arms, the'sleeve fitting exteriorly on the slotted end of the casing and being provided with slots through which the said bolts pass to adjustably secure the same, and means for simultaneously actuating the said calking hammers.
4. A rivet calking tool, comprising a cas'- ing, calking hammers pivoted in the said casing, an operat-ing piston for the said calliing hammers, a cap adjustably threaded on the outer end ofthe casing and-through 1 which extends the said piston, and means whereby to .lock said cap in a 4selected position of adjustment.
in testlmony whereof l have signed my name to this specication in the presence of two subscribing witnesses.
