(01. 248-38) This invention relates to holders for Christmas trees and the like andmore particularly to a rotatable support for Christmas trees.

An object of the invention is to provide an improved apparatus having a rotatable turntable for supporting a Christmas tree or the like.

Another object of the invention is to provide an improved electrically operated driving mechanism for the Christmas tree supporting turntable of my improved apparatus.

Another object of the invention is to provide an impoved rotatable support for Christmas trees of the character mentioned, which is simple in construction, and reliable and exact in function under all conditions of service.

The invention also comprises certain new and useful improvements in the construction, arrangement and combination of the several parts of which it is composed, as will be hereinafter more fully described and claimed.

In the accompanying drawings:

Fig. 7 is an enlarged section of a portion of the apparatus showing the electrical connections between the base and the turntable;

Fig. 8 is an enlarged section taken on the line 8-8 of Fig. 6 showing the manner of connecting the contact strips on the underside of the tumtable with the socket or receptacle on top of the turntable; and

Fig. 9 is an enlarged vertical'central section through the turntable and the base, showing the manner of rotatably mounting the turntable on the base.

Referring to the drawings and especially to Figs. 1, 2 and 3, the improved apparatus may comprise a supporting base 11, in the form of a rectangular board formed from plywood or the like. The underside of the base 11 has fastened. thereto a plurality of cross bars 12 adapted to rest on the floor or other suitable support.

The tree, the body of which is indicated at 13, is supported directly in a holder 14 which is mounted on a turntable 15 disposed a suitable distance above the base.

The Christmas tree holder 14 is described and claimed in another application for Letters Patent filed by me even date herewith, Serial Number 690,193.

As shown, the holder 14 comprises a main tubular body portion for receiving the trunk of the tree 13, the tree being secured therein by means of a plurality of winged screws16 (see Figs. 1 and 3). I

The tree holder 14 is formed with a plurality of feet 17 which flare outwardly from the main body portion and are detachably secured to the turntable 15.

For the purpose of fastening the holder 14 to the turntable 15, the top of the turntable is provided with a plurality of metal plates 18 (see Fig. 5) having upstanding threaded stems 19, there being one plate 18 for each of the feet 17. The plates 18 are secured to the turntable by means of screws 20. Interposed between the plates 18 and the feet 17 are washers 21 (see Fig. 3). Winged nuts 22 are mounted on the stems 19 and when these nuts are turned down tightly, the holder 14 is rigidly secured to the turntable 15. The construction is such that the holder 14 can be easily removed from the turntable 15. or mounted thereon when so desired.

For the purpose of rotatably mounting the turntable 15 on the base 11, the base has fixed thereto, as shown in Figs. 2, 3, 7 and 9, a block 23, made in two parts for a purpose to be hereinafter more fully described.

Fastened on top of the block 23 is a plate or disc 24 (see Fig. 9) having an opening 25 in its center.

The turntable 15 consists of a circular block of wood, although any other material can be used.- if so desired.

On the underside of the turntable 15 there is another circular piece of wood 26, somewhat smaller in diameter than the diameter of the main body of the turntable. These two blocks of wood constitute the main body of the tumtable and provide a strong and rigid member for supporting the Christmas tree.

If so desired, an annular groove 27 can be formed in the portion 26 of the turntable, to pro- Yide means for receiving a belt or the like (not shown) which may be applied thereto to either drive the turntable 15 from a suitable source of power, or to be driven by the turntable, when the turntable is rotated by mechanism such as that forming a portion of the present invention and hereinafter described.

The

portions

15 and 26 of the turntable are formed with a vertical central bore 28, as shown in Fla. 9.

Passing through the bore 28 is'a vertical spindle 29, threaded at its upper end as indicated at 30, and threaded at its lower end as indicated at 31.

A suitable ball bearing 32 is mounted on the upper portion of the turntable 15, said bearin including a cone nut 33 threaded on to the threads 30 of the spindle 29, a hub 34 mounted on top of the turntable l5, and balls 35.

Another ball bearing 36 is mounted on the under side of the block 26, said bearing including a cone nut 3'1 threaded on to the threads 31 of the spindle 29, a hub 38 fastened to the block 36, and balls 39.

The lower end of the spindle 29 passes downwardly through the opening 25 in the plate or disc 24. When the parts are being assembled on the turntable and the turntable is being assembled on the base 11. a nut 40 and washer 41 areparts, the two parts of the block 23 are not united until after the nut 40 has been applied to the spindle 29. After which the two parts of the block 23 can be secured together by means of screws 43, indicated by dotted lines in Fig. 9. The whole can then be secured to the base 11 by screws 44.

As shown in Figs. 1, 3 and 4, the driving mechanism for rotating the turntable 15 may comprise a roller 45 mounted on a shaft 46 journalled in a frame comprising a pair of spaced rectangular plates 4'1 and 48.

The

plates

47 and 48 are held spaced apart by means of tubular members 49.

The plates '47 and 48 are secured together by bolts 50, passed through the tubular members 49, nuts 51 being applied to the lower ends of the bolts so as to firmly clamp the parts together.

Mounted on the shaft 46 anddisposed between the plates 4'1 and 48, is a gear 52 which is in meshing relationship with a pinion 53 on the shaft 54 of an electric motor 55.

The driving mechanism, including the motor 55, the gears and the roller 45, is supported on a suitable frame 56, which is, in the present instance,

shown as comprising a Z-shaped member.

As shown in Fig. 3, the supporting frame 56 consists of an upper horizontal portion 5'1, a lower horizontal portion 58 and a substantially vertical portion 59 joined to the upper portion 5'1 and to the lower portion 58.

The portion 58 of the frame 56 is fastened to the base 11 by means of screws 60, and interposed between the portion 58 and the base 11 is a pad 61, which may be formed from rubber or any other suitable material.

The portion 5'7 of the frame 56 is fastened to the plate 48 heretofore referred to by welding, soldering, or in any other suitable manner.

For the purpose of supplying electric current to the motor and for illuminating lamps on the Christmas tree (not shown), a double-socket receptacle 62 is used. The receptacle 62 can be of the common type which can be purchased in many stores or commercial establishments, said receptacle having provision for receiving two

removable plugs

63 and 64 connected to conductors or electric light wires.

The conductor 65 connected to plug 63 may lead from a suitable source of electric current (not shown).

Conductor 66 leading from plug 64 is connected to the electric motor 55. In this way no switch will be required to control the operation of the motor 55.

In the several views of the drawings, plug 64 is shown in place on the receptacle 62, and with plug 63 also in place on said receptacle, electric current will be supplied to the motor 55 and consequently said motor will operate to drive the pinion 53 and gear 52 and roller 45.

Roller 45 is maintained in frictional engagement with the peripheral edge of the turntable 15 by the weight of the driving mechanism on the portion 5'1 of the frame 56. The roller 45 is adapted to rotate the turntable 15 at a considerable reduction in speed than the speed of said roller.

When either of the

plugs

63 or 64 are withdrawn or detached from the receptacle 62, no electric current will be supplied to the electric motor 55 and consequently the turntable 15 will not be rotated.

In order to supply electric current for lighting lamps which may be placed on the Christmas tree, a socket or single plug receptacle 6'1 is mounted on top of the turntable 15 at a.point adjacent to the tree holder 14.

As shown in Fig. 8, mounted on the underside of the lower portion 26 of the turntable 15 is a pair of

annular contact plates

68 and 69. The

plates

68 and 69 are concentrically disposed, the plate 68 being adjacent the periphery of the portion 26 of the turntable.

The

plates

66 and 69 are electrically connected to the socket or single plug receptacle 67, plate 68 being connected to one terminal of said receptacle by means of a rod '10 and plate 69 is connected to the other terminal of said receptacle by means of a rod '11. The rods '10 and '11 are passed through openings '12 and '13, respectively, in the turntable 15.

As'shown in Figs. 2, 3 and '1, operatively associated with the

contact plates

68 and 69, is a pair of rollers '14 and '15, respectively, which are carried by brass strips '16 and '17, respectively, mounted on a block '18 fastened to the base 11 underneath the turntable 15.

The brass strip '16 has secured thereto a bolt '19 which extends downwardly through the block '18 and base 11 and has fastened thereto one end of a conductor 80. The other end of the conductor 80 is secured to a conductor element 81 of the receptacle 62.

The brass strip '17 has secured thereto a bolt 82 which extends downwardly through the block '18 and base 11 and has fastened thereto one end of a conductor 83. The other end of conductor 83 is secured to a conductor element 84 of the receptacle 62.

As shown in Fig. '1, the

conductor elements

81 and 84 of the receptacle 62 are electrically connected to the two terminal contact members of the plug 63 by means of

contact members

85 and 86, respectively. In this way as long as plug 63 is disposed in the receptacle 62 electric current will be supplied to the single plug receptacle 6'! on top of turntable 15.

As shown in Fig. 3, the receptacle 67 is adapted to receive a plug 87 having a conductor 88 leading therefrom. The conductor 88 may have any suitable number of electric lamps (not shown) connected thereto and said lamps may be disposed in any desired manner on the Christmas tree.

By providing a tree lighting system in the manner just described, with the plug 87 removed from the receptacle 67, the turntable can be rotated without having the tree lamps illuminated. Furthermore, the tree lamps can be illuminated when the tree is stationary, if the plugs 63 and 8'7 are secured in their respective receptacles when the plug 64 is detached from its receptacle.

As shown in Fig. 2, the base 11 is adapted to be fitted with a cover 90, also formed of plywood or the same material as is the base. The cover 90 has side walls and a top, the top being preferably disposed substantially flush with the top of the turntable 15, and having an opening 91 therein to accommodate the turntable. Lateral shifting movements of the cover 90 are prevented by a rib 92 arranged around the periphery of the base 11, as shown in Figs. 1, 2 and 3. The side wall of the cover 90 adjacent to the receptacle 62 has an opening 93 therein, of ample dimensions to permit the insertion of the hand for the purpose of applying or removing the

plugs

63 and 64.

While one illustrative embodiment of the invention has been described in detail, it is not my intention to limit its scope to that embodiment or otherwise than by the terms of the appended claims.
