MOVINGQPICTUBE MACHINE.

Patented Jan. 21, 1908.

Application filed November 19. 1906. Serial No. 344\170- To all. whom it may concern:. Be it known that I, JOHN E. LAGERGREN, a citizen of the United States, residing in the borough of Brooklyn, in'the county of Kings,

city and State of New York, have invented certain new and useful Improvements in Moving-Picture Machines, of 'which the following is a specification.

This invention relates to the class of movpicture machines orap aratus sometimes led a biogra h or kinematograph" apparatus. In t 's'class of devices it may be briefl stated that'there is a lamp, such as an acety eno'lamp, ,a condenser containing a reflector and lens, a means for feeding astrip with ictures thereon, and projecting lenses for t owing the enlarged plctures on .a screen. The present invention relates in the main to an improved means for feeding thestrip of. pictures intermittently, as will be hereinafter described.

The invention, as embodied in a hand- I o erated machine suitable for family use, is

il ustrated in the accompanying drawings,

Figure 1 is a side elevation of the device on.

shows the feeding finger detached. Fig. 9

shows a variant of the feeding device for the strip of pictures. j

Referring to Fig. 1, particularly, A is the condenser, B the lamp, and C the projecting I lens-device. These are known and may be of the usual or of any known construction.

D is asuitable table or so portfor the 'aparatus, designated as a who e by E, for feedmg or moving the strip F of pictures. This feeding apparatus will now be described.

1 is anupright frame or support, preferably in the form of a'strong plate of metal secured to the table'D at 'y. In bearings 2' in the frame'is mounted a main shaft 3, having on it a crank 4 and a gear-wheel 5. This is the operating shaft and crank, to be employed when the device is to be operated by .the finger 17.

hand. The wheel 5 ears with a pinion 6, on a cam-shaft 7, mounted in a bracket 8 on the frame 1 at the front of 'the latter. This at the back, and the. Cprojecting lens-device C' in front, and it is hel a late 12, hinged at 13-to the frame, at one in place. and-guided by e ge thereof, and provided with studs 14 which pass throu h apertures in the plate'of the frame 1. T e plate 12 is hel down yieldingly over the strip by means of an. L- a shaped spring 15, of spring metal, pivotally attached to the back of the frame at wand its shorter arm made totake over the plate 12 by turning about said ivot w. e The purpose of the fee er, now to be described, is to feed the strip F intermittently over the sight-aperture 11, allowing. it to remain stationary for a moment thereat, and then quickly shifting the strip so as to bring the next succeeding icture mto osition at the said aperture. here shoul be about 20 exposures per second, and the shifting movement should, by preference, onl. occupy about one-eighth of the time emp oyed in making each exposure, the picture'beingat rest at the sight-aperture about seveneighths of the time occupied.

To effect the feeding movement, there is mounted on the bracket 8, ate, a vibratable or swinging guide 16, for a feeding finger 17 This finger is conveniently made from wire (seeFig. 8) andhas a'circular yoke to embrace the eccentric 10, and a stem carrying The stem plays in a slot or keeper-guide 18 in the swinging guide 16, and the latter has" cheek-pieces 19 between which plays the larger section of the eccen- It may be explained here that the eccentrio 10 has two disks, one a little larger than the other; the smaller. disk is embraced bizthe yoke of the finger 17 and the larger dis by 1ts content with. the cheeks 19, imparts a swinging or laterally vibrating movement to the device 16. Thus, when the shaft 7 is rotated, the eccentric swings the finger 17 laterally and protrudes it into engagement with an aperture 1) in the strip of pictures F; then swings and feeds the strip to an extent sufficient to put the next' succeeding picture into register with the sight-aperture; and then the finger withdraws and swings back again.-

There is in the frame or plate 1 at the point where the finger 17 engages the aperture 1) in the strip F, an aperture 20 for the finger 17 to play in, and in Fig. 7 is seen a slot 21 for the shaft 7 to play in. In Fig. 4 is seen a supporting device 22' for the endlessstrip F, of pictures. This sup ort may be of any kind.

An eccentric, as s' own in the principal figures, may be employed to operate the feeding finger 17 and swinging guide 1 6, but it is referred to employ the cam-device seen-in ig. 9, in order to get a quicker movement of the finger 17 in feedingthe strip F. In this figure it will be seen that the lar erplate or disk of the eccentric-10 is substltuted by a cam 23,which acts on pins or cheeks on the device 16 to impart a quick swinging movecould be two holes at the sides of the strip and two feeding fingers on the same stem to engage the said holes;

said strip, provided with feeding apertures,

and mechanism for intermittently feeding said strip, said mechanism comprising a rotating cam-shaft, an eccentric thereon, a feeding finger to engage the feeding apertures in the strip of pictures, said finger having a oke which embrac s the eccentric, a laterally vibratable guide provided with a keeper guideway for the finger, and means on the cam-shaft for engaging and vibrating said; guide, the eccentric serving to protrude and withdraw the feeding finger, and the vibrating guide serving to impart the to and fro feeding movement thereto.

. 2. A; moving picture machine, having'a holder and guide for a strip of pictures, the said strip having in it feeding apertures, and mechanism for feeding the strip of pictures in an intermittent manner,'said mechanism comprising a rotating'cam-shaft, an eccen- F tric thereon, a feeding finger havinga yoke which embraces said eccentric, a vibratable guide 16,.having a kee er-guideway in which plays the stem of said finger, and a cam' on said shaft which engages parts of the guide 16 on opposite sides and imparts an irregular movement to said guide.

the presence of two' subscribing witnesses.
