' My invention relates generally to a novel construction of a' phonographic disk record cabinet, record container or ejector'and more particularly to a novel manner of'constructing the ejector skeleton or assembling and securing the upper and lower endsof the partitions, which form the vertical, closely related parallel record holding compartments therein in conjunction withejector levers fulcrumed. in the lower portion of the compartments so as to formthe bottoms thereof,

whereby the records are effectively supported and ejected or stored in said compartments when in housed position.

For the purpose of illustrating my invention, I have shown in the accompanying V drawings one form thereof which isat presentp'referred by me, p v

Figure 1 represents a vertical, sectional view of a phonographic disk record ejector, its record arresting device, and their adjuncts, embodying my I invention, certain parts being'shown in elevation and the section being taken on line 1-1 Figure 2.

, Figure 2 represents a section online 22 Figure 1. i

Figure 3 represents a perspective view of the upper portion of a partition showing the gripping strips therefor and the manner of assembling a single partition between a pair of said strips.

Figure 4 represents on areduced scale a side elevation of a partition employed.

Figure 5 represents a side elevation showing onemannerof constructing the'ejector skeleton.- v 1 Similar numerals of reference indicate corresponding parts in the figures I Referring to the drawings i 1 designates my novel construction of phonographic disk decord cabinet,"the same comprisinga series of vertical parallel, closely related, record holding compartments 2, wherein the records '3 are contained, said compartments being formed between the parallel partitions t, whose front and rear edges-are preferably stripped with paper,

cloth or the like, as indicated at 5,and my' present invention relates 'more particularly to the manner of assembling or gripping'the top and bottom portionsof the partitions in a novel and expeditious manner so as to form the ejector skeleton. I'employ a lurality of wooden strips 6, which are all o one stand ard dimension both as to length, width and thickness, and which same can be cheaply 4 as stated, by-means of the same template I used for the upper holes 8, and I simultaneously bore or punch the holes .10 above the row ofholes 9 through which holes 10 passes the fulcrum rod 11 onwhich the ejector le-- versg12 are pivotally mounted, said.levers forming the bottoms of the record holding compartments 2 and. serving to' support'or eject the recordsS as Figure'l. i

' The ejector levers 12,-are fulcrumed atthewill be understood from rear of their centers of gravity and ma have the beveled front ends 13, and their top and bottom portions are preferably rectilinear for the sake of reducing the expense in inanufacturaand said top is provided with a longitudinal groove 14, the reariend ofthe'lever being provided with akicker 15 which abuts against the periphery of the record to be ejected, the proper rearward position of the records when in stowed or housed position being assured by the abutment or bumper 16.

In theformation of the skeleton comprising'the record holding compartm'entsQ, I

may assemble the partitions vertically or I may lay one of the end'partitions 4 upon a bed or table 17 with the three upper tie rods 18 standing vertically and the three lower tie rods 19 also standing vertically.

The fulcrum rod 11 is also placed in' its proper position standing vertically and the bottom ends of these rods may be temporarily held in position by any suitable means.

Anupper strip 6'and a lower strip 20'and a lever 12 is then dropped or placed in-position'upon the partition, said strips and lever being dropped down over the appropriate tie rods and fulcrum rod respectively. I next place in position another partition 4 and on v. the latter a pair of'strips 6 and 20, and a lever 12fand so on, these'elements being assembled by being droppedvertically upon the vertical tie rods 18, 1 9and' the fulcrumrod 11. After the requisite number of partitions and strips have been assembled to make the desired number of compartments, the upper ends of the 11 per and lower tie rods 18 and '19 and the in crum rod 11 have nuts screwed thereon, or if desired, a washer can be placed in position and the extremities of the tie rods and fulcrum rod riveted or headed over by a han'uner or other implement. The skeleton being now finished and the bottom 21 of the cabinet having been removed, the skeleton can be inserted upwardly from the bottom and is secured from forward movement by the rectangular frame 22, composed of the top 23, the bottom 2 1 and the sides .25. The forward end of the ejector skeleton is held against the franieworl: or strips 2a and 25 by any suitable means, and upon the bottom 21 being placed in the position seen, the skeleton will be rigidly held in the desired position, the nuts on the ends of the upper and lower tie rods 18 and 19 preferably abutting against the panels 36 to prevent side shifting.

it will befurther apparent that a skeleton constructed in accordance with the foregoing will be light, but strong and rigid, and inaddition theexpense of glu'eing, handling and heating the glue and the like is entirely obviated, as is also the expense of groov ing the top and bottom boards heretofore employed, and in addition the gripping action of each pair of the upper and lower strips will in practice have a tendency to prevent the partitions from warping, and further, there is no possibility of an individual partition shifting forwardly or backwardly with respect to any other partition since the provision of the tie'rods 18 and 19 will effectually preventthis and will. cause the front edges of the partitions or the compartments formed thereby to always properly align. H

It will be understood by those skilled in the art that when a record 3 is gently pushed into any one of the compartments 4 that the same will roll rearwardly upon its lever into the stowed or housed position seen in Figure 1, and when it is desired to eject a desired record, it is only necessary to depress the forward or beveled end 18 of an. ejector lever 12.

In practice, in devices of this character, the record as it is ejected or rolled gently forwardly is grasped between the thumb and forefinger of the operators hand which actuates the ejector lever. In case, however, of inattention or carelessness on the part of the operator, the record might roll out and drop upon the floor and thus be injured or damaged, and in order to effectually prevent this contingency, I employ my novel record arresting device comprising a flat inclined plate 26 which is hinged or pivotally attached atthe point 27 to the top of the finishing strip or its equivalent 28, said plate when dropped outwardly and downwardly being held at the limit of its downward movement at an angle of about fifteen to nineteen degrees from the llOllZOIlllfllO]? in substantially the position seen in Flgure 1 by means mete /o of the link connection 28 or its equivalent comprising the two members 29 and 30, which are. pivoted together at the point 31, the downward end of said link 29 being pivotally secured to the record arresting device 26, while the upper end of the link 30 is se cured to the vertical strip 25 or some s'imi lar point.

The talking machine disk records commonly in vogue rangefrom eight to'twelve inches, and in practice 1 position my novel record arresting device 26 and arrest its down ward movement so that it will be arrested at about the angle stated preferably about 17 to the ejector devices so as to provide proper clearance for a twelve inch record, as indicated in dotted lines in Figure 1, it being apparent that the record arresting device 26, the ejector levers 12 and the front edges of the partitionse are so collocated,

that when a maximum sized record, as a' twelve inch record assumes the position seen in dotted lines in Figure 1, its upper periphery 33 will readily clear the overhanging top portion 3% of the cabinet, while its rear orleft band edge as indicated at. the dotted are 32 will be temporarily contained and retained upright within the forward portion ofthe compartment 2, or within the front edges of a pair of partitions 4c.

. If desired, I may employ in addition to the bumper or abutment 16 a second bumper or abutment 35 located at about the point indicated in Figure 1 for arresting the rearward movement of the larger sized records,

both of said bumpers or ab-utments havingv their ends secured to the side panels 36 of the cabinet in any suitable manner.

While I have described the spacing strips 6 as being preferably of wood, it is evident thatthey may be of other materials, as card board, paste-board, vulcanized fibre or any other material, and by tightening the nuts on the fulcrum rod 11, the oscillatory action of the ejector levers'can be controlled to the desired extent. The fulcrum of each of the,

, of vertical partitions, which hangfreely from upper rods whose ends are dropped in grooves in horizontal upper bars. The lower ends of the Gullman partitions have no bottom spacing strips corresponding to my strips 20 and there are no clamping means or other fastening devices for causing the upper and lower ends of the Ciilhnan partitions to be tightly, rigidly and immovably gripped be- 1,701,479 I V e 3 tween the upper and lower spacing strips, and as Culhnan lacks the lower spacing strips, which Iemploy, it is obvious that the lower ends of his partitions are not tightly gripped or rigidly held at all. Cullman also lacks the rear kicker l5 which-I employ and which gives an instantaneous forward impulse to the ejected record. Where the kicker- -15 is omitted, the effect of the depression of,

the outer end of the ejector lever is to cause the record initially to hop or bounce up and down, whereas in my devicetherecord is smoothly and instantaneously ejected instantly on the. depression of the outer end of a lever.

It will now be apparent th at I have devised a novel and useful construction ofa skeleton for a disk record ejector and record arresting means therefor, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which will givein practice satisfactory and reliable results, it is to be understood that'the same is susceptible of modification in various particulars witho record holding compartments composed of vertical parallel partitions, horizontally dis-o posed upper and lower parallel spacing strips of one standard width at the upper and I lower endsof said partitions, the latter being tightly gripped at their upper and lower ends between'said spacing strips, a plurality of upper and lower transverse tie rods passing through said upper and lower spacing strips, clamping devices on the outer ends of said upper and lower tie rods for causing the ,upper and lower terminals of said partitions to be in rigid and immovable engagement with said upper and lower spacing strips, substantially horizontally disposed ejector levers fulcrumed in the lower portion of said compartments and forming both the bottoms thereof. and a support for records-when housed or ejected, a transverse lever supporting rod pass ng through the lower portion of sald partitions and through said levers at a point in the rear of the center of gravity of I said levers, whereby the front end of a lever vwhen unloaded automatically 7 gravitates downwardly, clamping devices on the outer ends of said lever supporting rod for caus- 1 ing the levers and partitions to be held in contact, and an upwardly extending kicker projectin to, facilitate the noiseless ejection of a record, the latter when in housed position being supabove' the rear portion of each lever portedon its lever at a point intermediate its'fulcrum and said kicker and against the latter.
