in. mensa? the city,T oi Louisville, county oi Jeiierson',
State of Kentucky, have invented a Handle' Lock for Pneumatic Tools, of which the iollowing is a specification.
iev.
SI the common type'of pneumatic hammers, the cylinderl or barrel has a screwthreadcd 'connection with theliandle portion; and, howevertight this connection may he: originally, the continual jarring oi the toolin'practical-use is liable to, affect the threadsl so este produce fa loosene'ss even when the parte are securely locked against rotation. l h f The principal object of my invention is to preventsuch lo'oseness. y
.The invention consistsdn the construction 'hereinafter described and claimed. 'f 1-In thefaccompanying drawings, which form part of this. specification, and. 'wherein like symbols refer to like parte wherever f @Ourthe of a s ecial tool for disengaging the cou ling f A illutifated ber?) is a strong piece of resilient stee whose.,
thy'occur, Figure 1 is a side view oi aneuinatic riveting hammer ecfluippcd'wit my coupling device; Fig, 2 is a ragmentary View a'rtly4 inelevation and partly in section; ig..-3 is a .detai1l pers ective view4 or" the '.uember; and, ig. 4 is a detail .viewv terloclrey. l
n Vp:eefumatic hammers of the ty e illustrated inthedrawing, .the rear'en 'of the mem er from the member with Whichit inbarrel bis reduced in diameter ,and screwthreaded so as .to ht inthe screw-threaded socketothe handle ortion 2: By arrangement, auann har shoulder ,is formed on the barrel opposite the end of the socket portionof lthe handle.' v According to my invention", the vlocking member 3 adapted for,- engagement fboth with` said shoulder and withfthe en d of said socket portion is interposed between them.
Fig. v3, the lookin memhody portion is of helical form with an in-' 'ternal diameterv suiiicient to .let it passt'oyer -thereduced end of the barrel.
y A Une, end of this helicall piece is bent transversely I to 'the toothjfformed thereon. -'lhiehent end off-the hiking-mem?) .ff-atherefo er yits in a; mortise provided theendo the Wall oi the'handle Patented March 23, 1909.
ermanently secured to said handle portion. '`l"1e ratohet.tooth at thel other end of said l locking' member is adapted to cooperate with ratchet teeth 6 provided thereior on the shoulder of the barrelf.
in practice, the helical member is firmly' secured to the end of the socket member, the valve block and valve are positioned in the socket, and then the threaded reduced end 'of the barrel is inserted into ,the threaded portion of said socket `and turned therein. During theturningof the barrel, the ratchet tooth 'on the end of the locking member rides over the ratchet teeth on the shoulder in the usual manner, and the helical spring is com- 'pressedtransversely Eventuali the end oi the barrel jams the valve b ook firmly against the bottom oi the socket, whereupon the several members act as a solid piece. In this osition, the tooth of the resilient 4locking evice automatically engages one of the teeth on the shoulder. oi the barrel and thus automatically locks the barrel against occasioned by a change' in the threads rcsultf ing from continuous jarring, -In order to guard against such looseness, the locking device is expanded peripherally until `its ratchet tooth rides over one or moreof the 'cooperating ratchet teeth on` the barrel.4
The engagement of the ratchet tooth of the lookin device thus expanded beynnditsf.l
norma diameter maintains a continuous Eeripheral pressure tending to @ern the arrel relative to the handle in the'proper direction to take up any looseness that may occur during the use of the tool. The qeripheral expansion of the locking metri erl may vhe conveniently' effected by means of an ordinary Spanner-wrench.
from the barrel, the toolillustrated n Fig. 4 isV especiallyl convenient, as it can e easily applied to t e tool and disengaged therefrom. .This toolcompr'ises a yoke 7, one end 8 of In order to d isengage the helicl spring which -is shaped to enter' the trisingular space between the helical member 'randzthe beveled surface of a tooth on the shoulder of they ,l'iarrel.
The other-end'o the yoke has le screw-threaded hole therein through which.;
extends a threaded bolt ,9. ln practice, the;
roby said' locking me'mloer.,v is
triangularend of theyole inserted .under licalsprng en [the othereiid-of the yoke is placed over the rear end of the socket portion of the handle with the bolt in alinement therewith. The bolt is then screwed inwardly with the result that, as the-inner end of the bolt bears against a fixed abutment, the power applied thereto is transferred directly to the helical member and drawsor pulls it backwardly away from the shoulder of the barrel. The tool will hold the helical spring thus disengaged as long, as desired, and thus the operation of screwing and-,unscrewinor the parts together are simplified and facilitated.
Obviously, the construction hereinbeorc described admits of considerablel variation without departing from my invention. For instance, the ratchet tooth may be formed on the end of the handle portion instead of on the barrel, in which case the .locking member could be permanently fixed to the So, too, the locking member may the ratchet teeth may be formed on 'the peripheral face of one o the members to be secured.
l'Vhat I claim is:
1. In a pneumatic tool, the combination with a handle member having a threaded socketv therein and a barrel member having areduced end portion threaded to enter said socket, of a resilient helical locking member interposed between said members, l the shoulder of said barrel member having l 'teeth formed thereon and said locking memberbeing fixed at onc end to said handlej member and being peripherally expanded l beyond its normal diameter n ,l other end adapted to co erate with said teeth the body portion of t ie locking menu l ber being clear of the handle member.
2. In a pneumatic tool, a handle piece having a socket, a barrel having a reduced end portion engaging said socket and ratchet l teeth on the shoulder formed by said re-- l duced end, and a helical member having x one end fixed to said handle and having its bother end adapted to interlock with said teeth said helical member being narrower than `the distance between the handle `mem ber and-said shoulder and being resilient peri )herally 'and transversely and being expan( ed beyond .its normal diameter.
3. The combination with the handle'member and the barrel member of a pneumatic tool of a resilient curved locking member i interposed between and adapted to engage l said members, and a yoke having one end i adapted to secure a purchase on the forward l face of said locking member and whoseother end comprises a movable part adapted to secure a purchase on the rear portlon of the handle.
