Application ala sepmr'ib'ery 25,1923. serial-N. 665,315;

` To all, whom it may concern:

kBe it known that` FRANK M. EDGAR,

citizen 'of the United States, residing at Detroit, in the county of Wayne and State of Micl'iigan, has invented certain new and useful Improvements in-Handle Assemblies,

of which the following is aspecication.

l'hisinvention relates to. door handle assemblies and has for its object a door handle assembly which gives a universal mounting for the door handle spindle and at the same vtime is provided with means for yieldingly Way of eliminating rattles which used to be so common with Windows. About the only yplace left Where rattles occur is 'in the lock. Locks often rattle due tolost motion between the roll-back, the stop and the bolt.

In the better class 'of automobile body construction it has been found necessary to use a` door handle Which has a spherical or ball-andsocket seat upon the-` escutcheon f plate. 'This is necessary in order to make up for variations in the positions of the looky and escutcheon plate on the surfaces of the door. Such ball-and-socket handle assemblies are already tobe found in the patented art, but these are open to several objections. Thosethat are not subjected to spring pressure very often rattle dueto the Wearing of the parts,[or'an improper` tit; those that are subjected Ito springs are usuall so designed thatl the one Who opens .the oor can pull the handle out against the resistance of the spring and very often thespring is not strong enough to 'force the handle back into its proper place. On the other hand, ifv-theylimit of its outward movement'.

in the handle assembly exercises a tortional efl'orton the spindle so as to take up 'any l slack or lost motion about' the rollsba'ck' in the lock.

Referring to the drawings:

Fig. 1 is aside elevation of an automobilev door lock.

Fig. 2 is a vertical section taken o-n the -line 2 2 of Fig. 1.

Fig. 3 isa section taken on the line 3 3 of, Fig. 2..V

Fig. 4 is a details of the escutcheon plate showing how the same may be rotated from 'the dotted line position to the full line position to place the spring under tort-ional stress for the' purpose of taking up the lost motion about the rollfback..

ais the front plateof the lock, b the cover plate; o thelever handle, Which is adapted to engage with the tail e of the roll-back f. This roll-back f is provided with a squared 'aperture L through which engages the spindle g of the handle. This roll-back ordinarily abuts up against the inside of the face plate 'y' of the lock casing; at least it abuts up against this when the latch bolt c is thrust clearA out by the spiral spring k. However, `when the beveled latch head sinks into the striker plate socket it may be stopped before the latch is projected to the In this event, the roll-back 'f is not jammed up against the inside ofthe face plalte j and consequently can chatter Ihack and forth, unlessy a spring is a'orded to drive4 it back In my improved construction, the door handle spindle' y vis a part ofthe, die casting which lincludes'also'the grip m which will preferably be coated with a vulcanized rubber or some suitable air-drying lacquer such as some of the pyroxylin compounds. The squared spindlev and thegri come together to form the shoulder n. ecured-.on the spindle at this point b v.means of ank oo against thefstop or inside Aof the face' plate.

upset or by the impression o a pointed tool,

is a collar o which has a sphericalouter surface. handle spindle, the escutcheon plate p is threaded over the s indle. Hence, when the collar is tied onto t e spindle the escutcheon plate'which is provided with a stamped concave, part spherical interior surface fits over the s herical collar. A combine tortional an compression spring r is .thenl Before the collar is secured to the threaded overthespindle g with one' end in a depression ofthe collar. An escutcheon back plate s is then threaded over the spindle and the flange t of the outer escutcheon l platej is peened or .turned over therim of the back escutcheon plate to lock the two together. The other end of the spring is anchored in the back escutcheon plate at the point u.

This spring serves to eizert pressure onA the spherical collar so as to hold the former against the spherical interior surface of the hub of the escutcheon plate. This holds the partstogether under sufficient yielding pressure so as-to `prevent rattling and take-up any wear.`

Now, in order to cause the spring 1 to take up the slack in the lock 'parts which may exist between the latch bolt, the inside of the face plate and the roll-back, it is necessary to put the spindle under a slight tortional stress when the escutcheon is assembledonto the door. This is simple enough. With the assembly referred to, when the front and back escutcheon plates are lockedltogether, the spring, spherical collar 4and the escutcheon plates. all forma eompleteunit. When the lock setter applies the handleto the door he lirst inserts the squared spindleI g through the drilled opening in the door and into the squared aperture in the hubjof the roll-back. He then gives'the escutcheon.

plate a turn of, say a quarter or a half turn; this puts the spring fr under a tortlonal strain and consequently forces the roll-back against its stop or the inside of thev face late. Y

Still a further advantage in this construe-- y tion is that. it provides an independent means for returning the door handle to its normal yposition when the grip is released. Very often the door handle will stick on an automobile body, the bolt spring. not having sufieient power to shoot both bolt and door handle back to their positions. This very often occurs when the door handle orsome ofthe lock parts need oil or unduly bind.

This often requires the occu ant ofthe car `to reach outside and turn .t e door handle before he can`- get his door toriatch. This difficulty .is very' much less liable to happen with the resent construction, forl the tortional spring 1" is in itself ordinarily suii cient to turnthe door handle to its initial position.

What I claim is: 1`. In a door handle assembly, the combi-V nation of an escutcheon provided with a front plateand a back plate, 'a handle spindle passing through theI plates and provided with a collar located between the plates, and

a spring bearing a ainst the back plate and thrusting `against t e collar for the purpose specified.

2. In a door handle assembly, the combi-- nation of an escutcheon plate comprising a front and a rear plate-spaced apart, a handle spindle passing through the plates 'and `provided with a collar, and a coil spring around the spindle having one end anchored in the collar and the; other end anchored in'the rear escutcheon plate and Ithrusting the collar against the inside of the fronta escutcheon plate.

3. In a door handle assembly, the combination of an escutcheon plate made up of a front and rear plate spaced a art,Ja handle spindle passing through thep ates and provided with a collar whlch has a surface. upon which the front escutcheon plate may rock, and a coil spring abutting against the inside of the rear escutcheon plate and thrustfing against the said collar.

4. In a door handle assembly, the 4combination of an escutcheon plate provided with 'front and'rear late members s aced a art,:

a handle spindle passinf throng the plates the front plate provided with a hub portion having a spherical interior concaved surface, the'handle spindle'being provided with a collar having a complementary spherical surface for engaging the concaved interior surface of the hub of the front escutcheon plate, and a spring coiled about the spindle and abutting against the inside ofthe rear.
