DOORSTOP Filed Sept. 10, 1951 2 Sheets-Sheet l Invcnior Patented Aug. 9, 1932 PATEN DANTE BIANoHI n n HARRY DE V'BIEZE, or HAWTHORNE, 'NEw JERSEY Application filed September 10, 1931. Serial No. 562,152.
The present invention relates to a door stop and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying novel construction, combination and arrangement of parts through the medium of which the door may be retained in any desired position.
Other objects of the invention are to provide a door stop of the aforementioned character which will be simple in construction, strong, durable, inconspicuous, eflicient and reliable in operation, and which may be manufactured and installed at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a view in side elevation of a lower portion of a door equipped with a stop in accordance with the present invention.
Figure 2 is a view in edge elevation.
Figure 3 is a view showing portions of the door broken away to show in side elevation, the upper and lower portions of the stop constituting the present invention.
Figure 4: is a view in vertical section taken substantially on the line M of Figure 1.
Figure 5 is a view in vertical section through the lower portion of the device.
Figure 6 is a view in elevation of the lower portion of the device.
Figure 7 is a view through the housing with one side removed.
Referring now to the drawings in detail,
40 it will be seen that the reference numeral 1 designates a lower portion of a door equipped with the usual knobs 2. The device con stituting the present invention comprises a housing 3 which is mounted in a pocket or recess provided therefor in the door 1 adjacent the free vertical edge of said door. The housing 3 has one edge flush with the free vertical edge of the door, and is closed at this point by a plate 4 which is screwed to the housing as at 5, and which is screwed to the door, asat 6.
One side of the housing 3 is closed by a removable plate 7. Plates 9 and 10 are fixed on the faces of the door 1 and are provided with centrally disposed outwardly projecting hub portions 7 and 12, respectively. A polygonal shaft 13 is journaled in the plates 9 and 10 and extends through the door 1 and the housing 3. The shaft 13 extends outwardly beyond the hub portions 11 and 12 and has fixed thereon the knobs 14: and 15.
. The hub portion 12 of the plate 10 and the hub portion of the knob 15 are provided with co-acting teeth 16 for retaining the shaft 13 against rotation. The hub portion of the knob 15 is designated by the reference numeral 17. I v
The hub portion 11 of the plate 9 has extending thereinto from its free end a socket 18 having a reduced extension 19. The socket 18 slidably receives the hub portion 20 of the knob 14;, said hub portion 20 having a socket 21 extending thereinto from its free end. A coil spring 23 encircles the shaft 13 and seats in the sockets 19 and 20 for yieldingly urging the shaft 13 in a direction to engage the teeth 16. A cam 24 is fixed on the shaft'13 for rotation therewith in the housing 3.
Depending from the lower edge of the housing 3 through the stile of the door 1 is an elongated tubular housing 25 having fixed on its lower end portion a depending cylinder 26 which is also disposed in a chamber provided therefor which extends upwardly into the door 1 from the lower edge thereof. At its lower end the. cylinder 26 is provided with outturned apertured flanges 27 for the passage ofsecuring screws for retaining the cylinder in position. 7
The plunger28 is operable vertically in the tubular housing 25 and projects upwardly therefrom into the housing 3 for operative engagement by the cam 24:. The coil spring 29 is disposed in the lower portion of the tubular housing 25 and has one end engaged on the cylinder 26 and the other end engaged with a collar 30 fixed on an intermediate portion of the plunger 28 for yieldingly urging said plunger upwardly.
The plunger 28 extends slidably through the upper end of the cylinder 26 into said cylinder and has threaded thereon a piston which is designated by the reference numeral In use, either of the knobs 11 1 or 15 is grasped and the shaft 13 is shifted longitudinally against the tension of the coil spring 23 to disengage the teeth 16 and permit the rotation of the shaft. Upon rotation of the shaft 13 the cam 24 engages the upper end of the plunger rod 28 and forces the same downwardly against the tension of the coil spring 29 to engage the resilient element 34:
-, with the floor 35. WVhen the knob which has shaft against rotation, said means including co-acting teeth on one of the hub portions and the adjacent knob, and acoil spring encircling the shaft and engaged with the other knob for yieldingly urging said shaft in a direction to engage the co-acting teeth, a collar fixed on an intermediate portion of the plunger rod, and a coil spring encircling said plunger rod and having one end in engagement with the cylinder and its other end engaged with the *collar for yieldingly urging the plunger rod in the opposite direction. In testimony whereof we aflix our signatures.

It is believed that the many advantages of a door stop in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as'illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
