COLLAPSIBLE TURN-TABLE.

To all whom it may concern:

Be it known that I, I JOHN P. HILL, a citizen of the United States, residing at Pulaski, in the county of Pulaski and State of Virginia, have invented a new and useful Collapsible Turn-Table, of which the fol.- lowing is a specification. 7

- The device forming the subject matter of this application is'a turntable adapted to be employed by section foremen and others for manipulating handor motor cars.

The invention aims toprovide a turntable which, may be folded into collapsed form and be carried readily upon a hand or motor car. 7 V v a The invention aims to improve the frame or track portion of the turntable, and to provide novel means for supporting the turntable for swinging movement;

- It is within the province of the disclosure I to improve generally and-to enhance the utility of devices of that typeto whichkthe present invention appertainsn .VVith the above and other objectsimview which will appear as the descriptionpros .ceeds, the invention resides in the combination and arrangement ofparts andlinthe details of construction hereinafter described and claimed, it being understood' that changes in the precise embodiment of the invention herein disclosed; can be made within the scope of what is claimed,:without departing-from the spirit of the invention.

Fig. 9 is a transverse section of the structure shown in Fig. 7; Fig. 10 is-a top planshowing the turntable of Fig; 7 in folded condition; Fig. 11 is a cross section taken approximately 1 on the line 11 11 of F igJ-lO. Fig. 12 is a side elevation'of' the structure shown in Fig. 6, parts being in section.

In" the accompanying drawings, the numeral 1 indicates the rails of a track, the supporting ties appearing at 2. V i I In carrying out the present invention there is provided a turntable comprising a collapsible frame embodying side 1 members or tracks 3 each carrying at one end an abutment 100.. The -tracks 3 may be anglemembers and when this constructure is resorted to, eachtrack- 3 comprises a base flange 4 and aside flange-5, 'the' sidefiangese ofthe respective tracks 3being disposedadjacent to each otherfso as to cooperate with the i'nneredges of the rails lina manner to be pointedout hereinafter. 'Mounted upon the outer faces of the side flanges 5 of the tracks 3 are sockets G-adapte'd to "receive rectangular fingers 7 formed atthe-ehds of the cross membersS which'preferably are in the formof' barsi r Y It' will now be understood that the frame i portion'of the turntable'maybe extended so as to cooperate with therailsl, as'clearly l-shown in Fig. 1, or, if' desired, and when the occasion" for the use ofjthesturntablexis passed, the frame of they turntable may be collapsed to the compact form shown in Fig.

3. A. means'is provided for holding the tracks-3 of the turntable frame inspaced;

relation to each otheras shown inFig; 1. of

thedrawings, and-with this endlin' view-,fa

hook 9 is pivoted as shown at"10]to one of I the side flanges 5 of the tracks 3. 7

The bill ofthe hook isdenoted by the na- 'meral'11-" and is adapted to :be" received iii an opening-'12' formed in'one ofthe terminal cross members 8'. The hook 9, therefore,'co-

acts'with' the said cross 'memberB and with the tracks to hold the frame in the eX,

tended position shown in Fig l and in such the'rails; 1

condition that it may; coacf with of the railroad trackfproper.

1 1 receiving for rotation a standard 15 provided at its upper end with an eye'16. The

standard 15 includes a reduced stem17 ex- Y tended downwardly through the base 22 and 15 carryingsuperposed nuts 18 which coact with the base to hold the. standard on the base against vertical displacement, without,

however, interfering with the rotation of the standard 15. Mounted to rock in the eye 16 of the standard 15 is a loop-shaped brace 20 which is fixed to and depends from the centraljcross member .8. I

Inpractical. operation, the base 22 ofthe supporting member is placed on one of the ties 2 as shown in Fig. 1, the tracks 3 extending longitudinally of the rails 1. Owing to the fact that the brace 20on the intermediate crossmember'8q. of the turntable frame is journaled for rockingmovement in the eye l6', the turntable frame may be inclined with respect to the horizontal, 'as shown in Fig. In this connection-it is to benoted that, as; indicated at 23,;the side flanges 5 of the tracks ,3 of theturntable frame engage with theinner edges of the rails l and thus the tracks of the turntableframe are alined vertically with the rails When the parts are positioned as above described, referring particularly to Fig. 2, the car which is to be manipulated istrundled onto the inclined turntable'tracks 3 until the car lies'above the supporting meinberand is balanced.

Then the turntable frame is rotated until it stands approximately at. right angles to the rails l as clearly shown in Fig. at, whereupon one end of the frame may be depressed and the'carmay be trundled off the turntable, to one side of the rails 1. In orderto return the car to'the rails, the operation above described is reversed. g I

, \Vhen the occasionifor the useof the turn-. table haspassed, the'billll of thehook 9 is withdrawn from the opening 12 in one of the criossmembers 8. upon loses its rigidity and the tracks 3 may be brought into close relation to each other asclearly shown in Fig. 3,.the fingers 7 of the cross members 8 rotating inthe sockets 6., The turntable now is in suchashape that it may be hung ,up readily on. the car or be otherwise supported thereon, the structure taking up'a minimum amount of room.

/ "In that formof the invention which is disclosed in Figs. 7, 8, 9, lO'and 11, a pair of side members or tracks are shown, the

The turntable theree same being provided, each, at one end with upstanding stops 62. The tracks 50 preferably are in the'form of angle members, each track comprising a vertical flange 51 and a horizontal flange 52. Sockets 53 are attached to the inner faces of the vertical flanges 51 of the tracks, and in the sockets 53 are mountedpivotally, the upturned ends I i 54 of a single cross member 55 reinforced by a depending, loop-shaped brace 56 mounted to rotatein an eye 57 constituting 'a part of a standard which is journaled in abase 58, after the manner in Fig. 7-

Bearings 59.are secured to the inner faces of the vertical flanges 51 of the tracks, and in the bearings are journaled the ends of loop-shaped brackets 60 havingseats 61 which receive the cross member 55.

When the seatsof the braces 60 are ,engagedwith the cross member 55, the tracks ing the braces 60, so that the seats 61 no longer engage with the cross member 55, the side members or tracks 50 maybe swung together as shown in Fig. 10. When the parts are thus arranged, a resilient latch 63 onqthe horizontal flange of one track cooperates with the horizontal fiange of the v 50 will be held in parallel relation. By lift- I other track, as shown in Fig. 11, to hold the tracks in nested parallelrelation.

.Having thus described the invention, what is claimed is v 1. Inaturntable, a cross member; tracks pivotedtothe ends of the cross member for movement toward and away from each other; and a supporting structure on which the cross member is mounted to rock vertically and to swing horizontally. in

2. In a turntable, a cross member; tracks pivoted to the ends of the cross member for movement toward and away from each other; means for holding-thetracks inparallel relation; and a support on which the cross member is mounted for'vertical'rock ing movement andfor horizontal swinging movement.
