CLARENCE R. MCCOLLUM, OI OAKLAND, CALIFORNIA, ASSIGNOR OF ONE-HALF TO FRANK R. IBOYSEN, OF OAKLAND,
CALIFORNIA.
CLOSURE-OPERATING DEVICE.
Application filed March 2,
To all whom it may concern Be it known that I, CLARENCE R. MoCoL- United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Im rovements in Closure-Operating Devices, 0 which the following is a specification.
The present invention relates to improvements in apparatus for automatically holding or propping a hinged or pivoted closure in open position when the closure is raised or opened and for automatically releasing the closure when the latter is moved up wardly past its propped-open position, whereby the closure will gravitate or may be moved freely into closed position.
The device of this invention is especially adapted for usein connection with hinged lids or covers of phonographs but may be used in connection with bin closures or for any other purpose to which it is suited.
An object of the invention is to provide a simply constructed and inexpensive device of the character described which may be more readily and easily attached to phonographs, bins or other devices having hinged or pivoted closures, without necessitating any changes in the construction of said phonographs, bins or other devices, and which will operate in a more reliable manner and not be subject to becoming readily deranged or broken.
Another object of the invention is to provide a device of the character described which will operate smoothly and noiselessly, prevent slamming of the closure, and be so disposed as not to interfere with the operation or use of the device to which it is attached.
A further object of the invention is to provide a device of the characterdescribed which is of such construct-ion that it may be 7 more readily and easily assembled and disassembled, and repaired than the devices of a similar nature now in use, and which will be superior to said devices by reason of its simplicity and durability of construction and its certainty and reliability of operation.
The invention possesses other advantages and features some of which, with the fore- Specification of Letters Patent.
Patented Feb. 14, 1922.
1921. Serial No. 448,997.
going'will be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings I have shown one form of the construction of my invention, but it is to be understood that I do not limit myself to such form since the invention as expressed in the claims may be embodied in a plurality of forms.
Referring to the drawing:
Figure 1 is a sectional view of a device or body such as a phonograph cabinet and closure therefor showing the invention attached thereto and in side elevation, the closure being closed.
Figure 2 is a view similar to Figure 1 showing the device as it would appear when the closure is raised or opened.
Figure 8 is a fragmentary plan view of the device as it would appear when the lid or closure is raised or opened.
Figure 4 is a top plan view of one of the details of the device.
Referring to the preferred form of the invention, as shown in the accompanying drawings, there is provided a propping member or supporting arm 1 pivoted as at 2 at one end to the lid, cover or closure 3, of a box, cabinet, or other device 4, the closure being hinged as at 5. The member or supporting arm 1 has a longitudinal slot 6 therein extending close to the other end thereof and a stud or projection 7 fixed to the body 1, to a side piece 8 thereof, extends into said slot. plate 9 held by screws or other fastenings 1.0 to the piece 8, and projects inwardly horizontally therefrom, having a head 12 of The stud 7 is carried by av the stud may The'pivot 2 is mounted on a plate 14 fastened by screws 15 to the inner side of the lid 3 preferably at a point on the side of the lid spaced outwardly from but near the hinges. The stud 7 is disposed above the body of the device sufficiently to provide for proper clearance of the arm 1 in operation. These points of mounting the parts may be varied as desired to suit the particular closure and device to which the invention is attached.
Means is provided for automatically causing, the supporting arm to be moved so as to bring the notch into engagement with the stud when the lid has been raised its full extent and is then allowed to gravitate or is pushed a slight distance downwardly, whereby the arm will be prevented from sliding relative to the stud and will be locked in raised or opened position. This means also acts. to automatically disengage and hold disengaged the notch and stud when the lid is raised slightly from its proposed open position, whereby the lid may then be closed by being allowed to gravitate or by being pushed into closed position.
The means aforementioned comprises a plurality of elements one of which is a rocker or trip member 16 preferably formed of a single strand of wire or the like bent to provide an eye or bearing 17 at one end and so as to provide divergent arms 18 and i 19', which arms at their pin juncture are loosely surrounds twisted to provide a laterally extending projection 20 having an eye 21 at its outer end. Thi projection 20 is disposed under so as to engage and support the arm 1. The outer end of the arm 18 has the eye 17 therein which eye is rotatable on one of the screws 10. The other arm 19 has a right angularly bent end forming a trip or stop member 22 which is disposed above the stud to one side thereof but so as to engage in the slot 6. The stud is notched as at 23 so as to receive said trip 22 when the trip is in one of its positions whereby the trip, will not interfere with the engagement of the stud in the notch 18.
Mounted in a bracket 24 secured to the body 4; rearwardly of the stud 7 is a weight member 25. A pivot pin 26 is supported in the bracket and is inserted through the weighthorizontally near one end thereof so that the weight may have a swinging movement forwardly and rearwardly on said pivot. The end of the weight, below the pivot, is bifurcated as at 27 and a pin 28 is inserted through the weight so as to extend across the slot provided by said bifurcation. A link 29 is pivoted at its lower end to the pin 28, extends upwardly through the eye 21 and is bent right angularly at 30. The stop extends over the side of the eye and presents accidental withdrawal of said link. A helical expansion spring 31 the link 29 and at its lower end rests upon a lateral extension 32 ofsaid link while its upper end engages said eye 21 so as to place the spring under its upper end to provide a stop When the lid or closure is down or shut the arm 1 lies in a position slightly inclined to the horizontal and depresses the projection 20 so as to compress the spring 31, the weight of the lid overcoming the tension or action of the spring. The weight lies in balanced position, forwardly in clined against the spring, which spring serves as a stop for said weight. The trip 22 engages in the slot in the arm 1 along the upper edge of saidslot, being placed under tension by the action of the spring 31 and the depression of the arm 19.
l l hen the lid is raised the pressure on the spring 31 is released and the weight is given a slight rearward movement as the arm 1 lifts clear of the projection 20 and the'spring expands. This brings the weight into nearly vertical position. When the lug reaches the lower end of the slot 6, the trip 22 passes the rear edge of the notch 13 trip, being thus removed, the trip snaps upwardly into the uppermost rear corner of said notch. At this time, the stud is forward of andbelow the notch. The operator releases hold upon the; lid and the lid will by its own weight move forwardly and downwardly as in closing. The front edge of the notch 13 is beveled so that as the lid lowers the lug will engage in the notch and prevents more than a very slight downward movement of the lid. As the lid lowers so as to bring the lug into the notch the downward pressure on the trip 22 rocks the member 16 so that the link 29 is lifted'upwardly. This communicates a pull to thelower end of theweight 25 and causes the weight to be thrown into a rearwardly inclined position, shown in full lines in Figure 2. Thus simultaneously with the movement of the arm 1 to cause the lug to engage in the notch, the weight is shifted and causes the projection 20 to be pushed upwardly and maintained in such position as to engage the under side of the arm 1.
and the downward pressure on the j The weight pushes upwardly on the lateral 7 extension 32 and the link 29. and through the spring 31, this pushing action is trans.- mitted to the eye 21, with which eye the upper end of the spring engages. Thus, when theweight is thrown over, the spring acts as a. stop and cushions the fall of the weight preventing disengagement whereby any noise which would otherwise be made, is
eliminated. The weight of the lid when notv held up by the operator rests slightly onthe member 20 and spring so as to prevent the spring from pushing the arm 1 upwardly and disengaging the lug 7 from the notch 18.
To lower the lid, it is lifted upwardly slightly. This disengages the lug 7 from the notch 13 and the weight 25 swings further rearwardly as shown in dotted lines in F igure 2 and lifts the link 29 and member 20 upwardly. This lifts the arm 1 so that the lug, though forward of the notch is below said notch and will not engage therein when the arm 1 slides forwardly. As the lid is lowered the arm 1 slides on the projection and lug 7. WVhen the lid is nearly closed the arm 1 depresses the member 20 which pushes downwardly on the spring 31 and lower end of the weight. This moves the weight back into forwardly inclined position, shown in Figure 1 and the device is set for another operation.
