WILLIAM J. TIBBITT, OF PHILADELPHIA, PENNSYLVANIA. f RIVET-SE ZT-RE'TAINING DEVICE.-
Specification o f Letters Patent.
Patented Dec. 5, 1905.
Application filed February 7, 1905. Serial No. 244,538.
To all whom it may concern-1 Be it known that I, WILLIAM J. TIBBITT, a citizen of vthe United States, residing in. the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Rivet-Set-Retaining Device, of which the following is a specification.
.My invention consists of a novel construction of a r1vet-set-retainingdevice adapted for use in a pneumatic, electric, or other'riv-' eting-cy'linder-whereby the rivet-set is prevented from being driven or forced out of the cylinder of the riveting-tool during the act of riveting.
It also consists of novel features of construction whereby the rivet-set may be read ily and easily inserted and removed from the riveting. tool or machine.
'It also consists of a novel construction of a rivet-sethaving a t-hreador threads thereon adapted to 'coact when inuse with'a contiguous :part of the riveter-cylinder.
'It further consists of novel featuresofcon-i;
struction, all as will be hereinafter fully set forth. p
Figure 1 represents a longitudinal view,- partly in section, of a rivet-set-retaining device embodying my invention. Fig. 2' .represents a longitudinal view, partly in section, similar to Fig. 1, but showing a rivet-set in a different relation to the'coacting cylinder. Fig. 3 represents a side elevation of, the rivetset removed from the tool. Fig. 4 repre:
, se'nts a longitudinal view, partly in section, of
another embodiment of my invention.
Similar numerals of reference indicatecorresponding parts in the figures.
Referring to the'drawin'gs, 1 designates the cylinder or casing'of a riveting-machine,hav-
ing an internal bore 2, within which a piston 3- is adapted to reciprocate and to impact against the end 4 of a rivet-set 5, the head 6 of'which I have shown in the present instance as being hollowed or cupped out, as at 7, adapting the same to form a button-head on' the finished rivet; but it is evident that the-head may be of any desired shape and cupped in any of the Ways well known in the art adaptingthe same to drive flush, button-head, or steeplechase rivetsor to shape the head' of-the rivet corresponding to the thread 9 on the rivet-set .13 designates the internal diameter of the cylinder at the rear of the chamber 12, which is slightly larger than the diameter of the shank 8 and is of such length that 'the ri-vet- V 'setwill have a sufficient amount of play andstill have the shank near its end within the internal diameter or bore 13, which will pre vent motive fluid escaping at this point and also serve to keep the rivet-set indirect alimement with the piston 2.
"In the embodiment shown in Fig. 4,- 14 designatesthe casing'or cylinder, within which. api'ston'lo is adapted to impact against the rivet-set 16, the latter having. a shank 17,
which near its end l8 is adapted to closely fit the internal bore 19 of the cylinder and having suitably located upon its shank 1-7 a thread 20. -21 designates a chamber located beyond-the bore 19, near the end. of the-tool, which latter has the-internal thread 22, adapt ed to receive the thread 20. In this embodiment (shown in Fig. 1) I have only shown-one right thread, while in Figs. 1, 2, and 3 I have shown two left threads in the cylinder and r two left threads on the rivet-set, it being evi dent that either a rightor left thread may be employed without departing from thespiritof myinvention and also that one. or more threads may be used in the cylinder or on the rivet-set or.with both rivet-set and cylinder. 'Lhave not-shown the ports and passages in the cylinder for the motive fluid, as the same per se forms'no part of my present invention.
The operation is as follows:' The rivet-set is inserted in the end of the cylinder by turning said set, the thread thereon engaging with the internal thread of. the cylinder, the enlarged chamber to the rear of the thread being of such length that the set may reciprocate therein without said rivet-set thread striking against the internal thread of thecylinder.
. The end of the rivet-set shank willbe within the bore 13 or 19. The nose ll of the cylin der may be reinforced or have a ring 23 secured thereon if necessary to increase the strength of the cylinder, as I have shown in dotted lines in Fig. 1, this ring being omitor tool than there is in the construction here- 7 tofore employed.
Heretofore in the art it has been common to employ a spring or clip which fits in a groove on the head of the rivet-set and a corresponding groove .on the end of the cylinder; but owing to the heating of the rivet-set during the riveting operation and the consequent heating of the spring it has been found impossible to retain the temper in the latter, which becomes useless in a very short time.
My device does not increase the number of parts and. can be very cheaply manufactured, at the same time being very durable and brings about the desired resultnamely, a rivet-set easily inserted and removed from the riveter-cylinder and during the riveting operation retained therein and prevented from being accidentally driven out of the cylinder.
While I have shown my device as being applicable to riveting-hammers, it is evident that the same'may be employed in any machine, such as a chipping, calking, flue-beading, or other impact tool wherein a reciprocating piston impacts against the shank of a working tool. As is well-known to those skilled in the art, in the practical use of riveters on bridgework and structural-steel work and shipwork great annoyance and inconvenience result from the accidental loss of pistons and rivetsets by their being driven out of the tool-cylinder, whereas by the use of my invention all such loss is avoided.
It will be evident that various changes may be made by those skilled in the art which may come within the scope of my invention, and I do not, therefore, desire to be limited in every each side of said threads being a plain cylindrical surface.
2, In a device of the character described, a rivet-set or other working tool having a thread on the shank intermediate the ends thereof, a casing provided with means at its outer end for engaging said thread, and a chamber within said casing for permitting the reciprocation of said working tool.
3. In a device of the character described, a casing having an internal thread at the outer end thereof, a chamber contiguous to said thread and a rivet-set having a thread thereon intermediate its ends adapted to engage with the cylinder-thread.
4. In a device of the character described, a cylinder having a thread in the outer end thereof, a chamber adjoining said thread, a rivet-set having a shank therefor, and means on the shank between its ends adapted to engage the cylinder-thread whereby said set may be inserted in said cylinder and retained therein during the riveting operation.
5. In a device of the character described, a cylinder provided with an internal thread at the outer end thereof, and a chamber contiguous to said internal thread, a rivet-set provided with a thread on the shank thereof intermediate its ends, the diameter of said chamber being greater than a cross-section of said rivet-set taken through said rivet-set thread, and a bearing beyond said chamber in which the shank of said rivet-set fits.
6. The combination of a cylinder having its forward end internally threaded at its outer portion 10 and a chamber 12 at the rear of said threads, said chamber terminating in the bore 13 of reduced diameter, with a working tool, having a shank, said shank having a thread thereon intermediate its ends.
