DOORCHECK.

Application filed July 11,

To all whom e'tmey concern:

Be it known that I, GEORGE FAUsER, a citizen of the United States, residing at De# troit, in the county of lVayne and State of Michigan, have invented certa-in new and useful Improvementsi in Doorchecks, of which the following is a specification.

This invention relates to door checks and has for its object a door check of simple construction which will effectively check an automobile door and which will be concealed from sight when the door is closed.

In the drawings:

Fig. l is a top plan view of the check applied to an automobile door, showing the door thrown open in dotted lines. I

Figi 2 is an inside elevation of the door with some of parts broken away.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. 4. is a section on the line 4-4 of Fifi'. l.

Fig. 5 is a section on the line 5--5 of Fig. 4.

Fig. bisv a detail of the twoplates used on the end of the check link.

Thisisa door check intended to be used onthe top of the dodi1 on the under side of the header. It is especially designed and adapted for automobile closed bodies. y Doorl checks of this general type are not `broadly new, but the improved door check about to be described has-novelty in the structural arrangements and employs a buffer. or shock absorbing spring which takes the tearing strains and the' shock of the door when being brought up short. j

.The pivotanchor which is an 'angle plate a is secured to the inside of the door header by screws b. This places the entire strain of the door upon the entire cross section of the header, so-that it is practically impossiblewith any ordinary effort to dislocate the plate from the header.

The slotted guide plate c` issecured to the top of the door by screws d. In most checks of kthis type the slotted plate is on the other sidenof the header consequently when the door reaches the limit of its movement the tearing strain'on the slotted plate is crosswise thereof, and calculated tol tear it from the header. By employing an angle plate the strain onthe pivot member is communicated to the entire cross section of the 1924.A serial No. 725368.

header, and, as will appear from the dotted one end, which will permit thc entry of the slide, and the notches may then be slid over the extended edges of the restrictedportion of the slot. This forms a convenient assembly, as when the parts are secured to the door, the slide never reaches the enlarged portion of the slot.

The slide itself is secured by a riveting operation to the end of the link g by means of a screw machine stud j. This forms a Ypivot for the slide on the end ofI the guide. The end ofthe stud is enlarged as at lc, and

`against thisabutsthe smal-l washer m. A

rub platen is pressed up into the slide by the coil spring 0. This rub plate projects out beyond the notches f so as to boar against the edges of the slotted plates which form the track on which the slide travels.

This spring, together with the rub plate,y

therefore takes up all looseness between the slide and the slotted plate and therefore prevents any rattlingy of the slide in its guide--a most desirable feature in connection with automobile body construction, where every rattle must be eliminated.

The arrangement of the slotted plate on the door while the pivot anchor.` is on the header is very importanty in'connection with thev use of the buffing element, nowto be described. A strap p is blanked out of the same Vmaterialthat forms the slotted plate. This forms acentering element, fora coil buffer vspring-g, while a smaller strip ,of metal r, spot-welded to the under side of the plate, is crimped over the last coi'l, as shown in Fig. 4, to securely .anchor this heavy, stro-ng buffer spring to the end of the slot. Now with the arrangement of the slotted plate on the door and with the dQor being This Y slot 1s provided with an enlargement h at checked when it is in a substantially perarranged to straddle lthe inside edges of tha apparent that the entire checking thrust `comes on the coil spring, which is located at the inner end of the slotted plate. The result is that the checking shock isI largely absorbed in the spring Without communicating tearing stralns to the fixtures of the element, 'and without making a disagreeable butter spring when the ,checking element isY reached.

"hat I) claim is:f 1. In a door check, the combination of a header anchor adapted to be securcdto the under side of the header, a slottedsplate adapted to .be secured to the top of the door longitudinally of the door edge, `a check link pivoted to the header anchor and a slide secured in the slotted plate, and a coiled butter cushion spring secured 'in the inner end of the slotted plate for taking substantially all the thrust on the parts when the limit of the door swing is reached.

9.. In a door check, the combination ot' a .header anchor adapted to be secured to .the

under side ofthe headerfa slotted plate adapted to'be secured to the top of the door longitudinally of the door edge, a check link pivoted to the header anchor, a sl1de secured in` the' slotted plate, and a yieldable Vbutter element secured in the inner end ot the slotted plate for taking substantially all the thrust on the parts /when the liit of the door swing is reached.

3. A door check, comprising an anchor plate, a slotted plate, a check 'link pivoted 'to rthe anchor plate, and a slide pivoted to the other end. of the anchor plate and l comprising a stamped plate with turned down sides that are notched, which notches are the slotted plate, the said slotted plate pro.

vided with a struck-out strap portion at one end of the slot, and a coil sping cen- ,t'ered over such strap portion and nchored fthereon, the said coil spring arranged to engage the slide at the end of the checking movement to absorb` the shock.

5. A. door check, comprising an anchor plate, a slotted plate, a check link pivoted to the anchor plate and slidably engaging the slotted plate, thesaid slotted plate provided with a spring centering member at one end of the slot, a coil spring centered over such centering member andi'a'nchored thereon, the said coil springarranged to engage the slide at the end) ofthe checking movement to absorb theshock, and a clip member secured to one end of' the slotted plate and crimped over a coil of the spring to so anchor the coil spring on the plate. i

6. In a. door check, the. combination of a header anchor adapted to\be secured tothe under side of the header, a slotted plate adapted to be seemed to the top of the doo-r longitudinally of the door ledge, said plate having an enlargement of the slot at its outer end, a check link pivoted to the header anchor, a slide comprising a :(plate with turned down sides having notches therein for straddlirrg the edges of the slotted plate on the inside of the plate at the slot, the

said slide being assembled over such edges' through 'the enlargement at the outer end of the slot, a stud for pivoting the slide to the end of the link having an enlarged head, a rub plate engaging anound said stud and arranged to bear against the under side of the slotted plate, and a coil spring engaging .between the abut-ment and said rub'plate.

In testimony whereof I have affixed my signature. y

GEORGE FAU SER.
