MAGAZINE FOR MOVING-PICTURE KAOHINES.

Specification of Letters Patent.

- Patented Dec. 3, 1907.

A pli ation m larch 28.1907. Serial No. 865.150.

T 0 all whom it may concern:

Be it known that I, JOHN J. PINK, a citizen of the United States, residing in the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Magazines for Moving Picture Machines, of which the following is a full, clear, and exact description.

My invention relates to certain new and useful improvements in magazines for moving picture machines, the object of the invention being to provide a simple, substantial and practically fire proof magazine which may e readily attached to or removed from machines of this class.

Another object is to provide an entrance to the ma azine groper, through which the reel may e rea ily inserted or removed, which entrance or opening is uncovered by sliding or telescoping the cover upon the receptacle.

The invention further relates to other novel features of construction a description of which will be found in the followin specification and the essential features 0 which will be more definitely pointed out in the claims appended hereto.

The invention is clearly illustrated in the drawings furnished herewith in which Fi e 1 is a side view of a magazine embodymg my improvements. Fi 2 is a view looking at the opposite side of the same. Fig. 4 is a vertical section taken on the line 4-4 Fig. 3, the reel or s 001 being removed from the magazine. F ig. 5 is a vertical cross section taken on the line 55 Fig. 1. Fi 6, 7, 8 and 9 are fragmental side views 0 the side sections of the magazine. Figs. 10 and 11 are side views of certain reinforcing washers used in hinging or pivoting the cover upon the receptacle. Fig. 12 IS a perspective view of a hollow rivet. mental view of the cover looking in the lrection of the arrow 13 in Fig. 4. Fig. 14 is a similar view of the receptacle. Fig. 15 is a plan view of a roller and its bracket, and Fig. 16 is a similar view of another guide roller and its bracket.

In these views 10, represents a base or standard, which is adapted to be bolted or otherwise secured upon the moving picture machine, a fragment of which appears at A. Said standard contains an arm 11, to which the casing or magazine proper is secured.

I Said arm is formed with a ournal bearing Fig. 13 is a fra .13, at its uppler end, in which is journaled a spindle 20, t at carries the reel or spool B.

A second spindle or shaft 40, is journaled in the lower end of the standard, which spindle carries a grooved pulley 41, and a crank 42, the crank furnishing means for rotating the shaft 40. The spindle 20, carries a grooved pulley 21, which is-connected to the pulley 41, by a belt 22, as clearly shown in the drawings, and said spindle is formed with a circumferential groove 23, in which rests a spring latch 24, that is fastened u on the arm 11. Except for the groove an spring latch the spindle is free to be withdrawn from its bearing, and said groove and spring latch furnish means for locking the spindle against longitudinal movement in the hearing. The spindle also bears a key 25, which seats a groove in the hub of the reel.

The arm 11, of the base has secured toit, a brace 12,which is provided with radial strengthening arms 13, to which one of the walls of the receptacle is riveted. This brace acts as a stiffening member for the wall of the magazine thus avoiding any buckling or warping of said wall. The magazine proper is shown at 50, and contains two

halves

51, 52, the half 51, being secured to the standard and serving as a receptacle, and the half 52, serving as the cover and being hinged or pivoted to the half 51, and telescoping therein. The rece tacle 51, is preferably formed of two

si e plates

53, 54, which are practically semicircular in form, and connected b a back late 55. The cover 52 is likewise ormed 0 two sides 56-57, approximately semi-circular in form, and connected by a back plate 58. The

side plates

56, 54, of the cover and receptacle are each formed with a pivot opening that is concentric withrespect to the curved margin or periphery of the plates, and each plate has riveted'to itselfat its center, a reinforcing metal washer 60. A spacing washer 61 is inter osed between the plates 56-54 to prevent t e projecting headsof the rivets from striking each other and thereby interfering with the movement of the cover upon the receptacle. The two lates 5654 are pivotally secured together a rivet 63 which is headed on the outer aces of the washers 60. The side plates 5753 are also perforated at their axes, the holes however eing somewhat lar er than the holes for the rivet 63, and said

ates

57, 53 are each provided with a reinforcing washer 59. A

spacing washer 59" is interposed between and holds it in position u on the s indle.

The lower meeting e ges of t e

back plates

55, 58, are cut away at 55*, 58 to magazlne, be

receive

idle rollers

70, 71, which rollers are journaled in

brackets

72, 73 riveted or other wise secured upon the

halves

51, 52, of the magazine. Said rollers guide the ribbon or film in its passage to and from the film spool. A hook 74 is pivotedupon the rece tacle 51, and engages with a pin 75, upon t e cover 52, to lock the cover down upon the receptacle 51. In operation, the cover 1s swung into the receptacle 51 to expose the interior, the belt 22, is removed from the pulleys, the spindle 20 released from the spring latch 24, and the s indle withdrawn from the reel or spool B. The reel may then be removed from the magazine and another reel substituted for the one removed. The s indle 20 is then thrust through the hub of the reel, the cover drawn down and locked in place, and the belt placed upon the pulleys. It is understood that in o erating the moving picture machines of whic the magazines form a art, the ribbon or film is unrolled from tlih reel B, and drawn through the machine. It may afterwards be re- Wound upon the reel by turning the crank 42.

In magazines of this class, it is exceedingly important, that the ribbon within the rotected from fire, -as said ribbon is usua y composed of highly combustible and inflamma le material, and this magazine has been particularly designed wit a view of meeting said re uirementsl It should be noted that when t e cover is shut, there are practically noapertures through which fire may communicate with the interior of the magazine. Furthermore, when the magazine is opened to expose the interior no additional space is required for the cover, so that economy of space may be had without complicating the structure. This is articularly advantageous for the reason t at these machines are frequentl set up in closely confined quarters, whic makes it necessary to economize space.

I claim as new and desire to secure by Letters Patent:
