To all whom it may concern:

Be it known that I, DALLAs C. Noon- WORTH, a citizen of the United States, residing at Ghicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Movingficture Machines; and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

I tently' drawing the This invention relates to improvements in moving picture machines.

- The object of the invention is to provide a machine of this character having an imroved film-holding mechanism whereby the m is held and comes in contact with the machine only along its edges, thereby obviating all danger of injury to the picture surface of the film.

Another object is to provide an improved construction and arrangement of door for supporting the objective lens and picture age whereby said door and the arts supported thereby are swung outwar y.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims.

. in the accompanying drawings, Figure 1 is an enlarged vertical sectional view; Fig. 2 is a horizontal sectional view through the su gifting frame, the door and the filmho g and guiding devices; Fig. 3 is a front view of the face plate showing the film channel and opening through which the light passes, and also showing the film guide strips; and Fig. 1 is an enlarged detail sectional view showin the means for intermitm through the machine.

Referring more particularly to the drawings, 1 denotes the frame of the machine which is here shown and preferably consists of a base or foot section, 2, to which are bolted or otherwise secured supporting standards, 3, said standards being connected at. their upper end by a curved cross bar, 1,

which forms a handle by means of which the machine may he carried. in the standards, 3, are formed vertically disposed guide channels, 5, in which is slidably mounted a frame, 6, in which are arranged the operating devices of the machine.

To the side pieces of the frame, 6, is secured a face plate, 7,

on the forward side of cured tothe suitable manner.

which are formed vertically disposed guide flanges, 8, which provide a channel through which the film is adapted to move. The film is held in the guide channel by means of a gage bar or plate, 9, which is su ported in position by horizontally dispose bars, 10, which are secured to said plate at one end and at their opposite ends are secured to a door, 12, which is hingedly mounted on one of the upright standards, 3, and adapted to swing outwardly threon and to carry the gage plate out of engagement with the film when desired. The door, 12, closes against a suitable stop formed on the opposite standard, 3, and is held in closed position by means of a suitable catch, 13. in the door, 12, is formed an opening, 14, in which is arranged the objective lens holder, 15, said holder being also moved outwardly when the door is opened.

in the channel formed by the flanges, 8, are arranged tension bars or strips, 16. Said strips are disposed between the film and the face plate and are adapted to press the edge of the film against the gage late, 9, said plate beingprovided with a ongitudinally disposed recess or channel, 17, so that the film will not engage the same except at its opposite edges. The tension strips, 16, are he d in yielding engagement with the edges of the film by means of tension springs, 18, which are arranged on the rear sideof the face plate adjacent to the upper and lower edges thereof, as shown. The'outer ends of the springs, 18, are connected. to the strips, 16, by means of screws or other fastening devices, 19, which are passed through spacing blocks, 20, and screwed into the strips, 16. The spacing blocks, 20, are arranged in a ertures formed in the face 'late to receive t e same. Across each of t e springs, 18, midway between their ends, is arranged a bail, 21, the opposite ends of which are sei'ear side of the face plate in any In the bails, 21, are arranged tension screws, 22, the inner ends of which are adapted to be screwed into engagement with the springs, 18, and provide means whereby the tension of the same is regulated. On one side of the frame, 6, are arranged operating gears, 27, on the shaft, 29, of one of which is fixedly mounted a worm gear, 31, which is adapted to engage a worm, 32, on a transversely dis osed shaft, 33, journaled in a suitable bearing bracket,, 34, secured to 1 mental flange,

the frame, 6. On the rear end of the shaft, 33, is fixedly mounted a shutter, 35, which is preferably in the form of a thin segmental plate and is adapted to be revolved by the train of gears, 27, through the medium 0 the worm gears, 31 and 32.

In the u per end of the frame are mounted toothed fRm feeding wheels, 37, around which the film passes from the reel 38, which is mounted on the upper end of the machine. The film is provided along its 0 posite edges with a series of apertures wit which the teeth on the wheel, 37, engage, thus forming a positive connection between the wheels and the film. The film is held in engagement with the wheels, 37 by means of grooved rollers, 39, which are revolubly mounted in an arm, 40, formed on a sleeve, 41, which is pivoted on a stub shaft, 42, journaled in a caring bracket, 43, formed on the upper portion of the frame, 6. The sleeve, 41, is provided with a'finger piece, 44, by means of which the arm, '40, is operated to enga e the grooved rollers with the wheels 37 T e sleeve, 41, is also provided with a radially projecting lug, 45, with which is engaged a at holding s ring, 46.

On a suitab y mounted shaft, 47, j ournaled in the lower end of the frame, 6, are lower toothed feed wheels, 48, the teeth of which are adapted to engage the apertures in the edges 0 the film adjacent to the lower end of the face plate, 7, said film bein held in engagement with the toothed wheei s, 48, by means of grooved rollers, 49, which are revolubly mounted on a shaft, 50, carried by an arm, 51,- fixed on a sleeve, 52, which is plvoted on a shaft, 53, on the lower end of one of the side bars of the frame, 6. The lower portion of the film where the same passes between the wheels, 48, and the rollers, 50, is protected by a curved shield or guard plate, 54.

On the shaft, 47, adjacent to one end thereof is fixedlf mounted an operating wheel, 55, said whee being in the form of a Maltese cross having notches, 56, with which is adapted to be engaged a pin, 57, which is secured to and projects laterally from an operating disk 58, whereby when said disk is revolved, the motion thereof is imparted thro h the pin, 57, to the operating wheel, 55, w 'ch is intermittentl turned by the engagement of said pin with the notches, 56, therein, to the distance of one picture for each revolution of the disk, 58. The ar-' rangement of these parts and the shutter operating worm gears is such that the shutter will be ven two revolutions for each movement 0 the -operating wheel, 55. On the disk, 58, is formed a radially projecting seg- 59, which is ada ted to en age with the curved outer edge of t e arms 0 the cross-shaped operating wheel, 55.

'60, and arranging the s Arranged at the rear of the shutter is a sheet metal protecting plate, 60, which is supported in position upon the frame, 6, by means of rearwardly-projecting supporting arms or bars, 61. The plate, 60, is provided near its upper edge with a light-opening, 62 through which the light from the lantern is adapted to pass. By roviding the plate,

hutter in rear of the or between the same and the light, the film will be protected to a great extent from the heat of the light, and much of the danger of the film becoming ignited is thus ehmiis d nglng h d i l y construct' an arra t e 001' to swing outwardl y inthe forward side of the supporting frame of the machine, and arranging the picture gage and lens holder on the door so as to be moved therewith, access may be readily had to the film and the threading and arranging of the same thereby greatly facilitated.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:
