invention, but-I would have it understood Tooll whom it" may' colic-em:

. 'Be it kno'wnthat I, JAMES AQGAMERON, a

'citizen-ofthe' Unit-ed States, and a resident l'of' the borou h of "Brooklyn, in the county of Kings,city and State of New York, have invented *certainf new and useful Improve- .ments in' Moving --P ieture Machines, of

which the'followi'ng is a specification.

The'obj'ect-ofmyinvention is in enera'l to protect the'film during its passage t rough' the macIiinei-" Fot this purpose I pro ose to coverf-thefilmmoving mechanism the machine withafireproof-casing or shield, l be'inclosed and prowhereby thefilm wi tected during its entire movement through the-machine.---And in this connection one feature of my" invention consists inbuildin a fireproofcasing-in such way as-toutiliz' the frameworkof the machine as a part of the casing. I

variousother objects and features of the invention wil lqappear' as the specification proceeds.

'-In the-accompanying drawings have illustratedi a" 'preferred embodiment of my that various changes and modifications may bemade'therein without departing from the spirit and scope of the invention.

In thedrawingsi Figure 1 is a perspeclower film; containers being broken away for want of room. 2is a similar view with thedoor of the-casing swung open. In this view the film moving mechanismof themechine is indicated in dotted lines. Fig.3 is

a-pers'pective view like Fi 1, looking at the o posite side of the mac 'ne. pf! anview' of a slightly modified formof... the invention, and Fig; is a broken detail view of -the modification illustrated in Fig.v 4. v i

Like-reference characters refer to corresponding parts throughout the several views.

* The invention constitutesein a preferred embodimenta substantially rectangular cas- "in madeup of the substantially parallel si e walls 1 and .2 and the substantially .parallel front and rear walls? and 4 respec- -'tively. .This Ieasing is made to inclose the. film moving mechanism of the machine, and

in order. to permit convenient access to such -film=movingmechanism, the casing is providedwith a movable part or door. To allow of the greatest freedom in the thrcadin up ?=of-the machine; this door is preferab :made comparatively large, and in the.

are made to swing openas a door. Thus, as shown in the drawings, the two contiguous sides. 1 and 3 are relatively fixed, while the two opposite sides 2 and 4 form in fact an augular door mounted on a pivot or pivots. .These pivots in "the present instance are shown as pintles 5 and 6 carried by the door, "WlllCll engage in pivot openings in lugs 7 and 8 on the fixed sidewall of the casing.

An importantfeature of my invention consists in utilizingthe .frame of the ma- Patented Mar.3,1914.

I preferred form two-whole sides of the casing I chine as a portion of the casing. Thus, as

illustrated in the drawings, the fixed side wall '1 is in reality-theside frame of the machine which' serves as the support for the film moving mechanism, this mechanism being indicated in general by the figure 9. The film moving mechanism is-thus supported on the inner wall of the frame,-while gearing 10 for operating such-mechanism is disposed on the outer wall of thejframe, as indicated in Fig. 3. When the frame-is thus made to serve as a part of the casing, it is preferably madesubstantially-continuous so as to serve as a continuous wall.- The front wall 3 which is also preferably rigid,ma or may xed side wall. Preferably, as indicated, itis cast integral with the frame so as to in fact constitutean angularfront portion of-the frame.

Both the upper film support 11 and the lower film receiver12may be secured to and be supported direetupon the frame.

The rear-wall portion4 of the door is providedwith an aperture 13 to register with the exposure opening 14 of the machine, and the front wall 3 is provided with a corre- T he door may. also nism. For instance, it may have an opening Kermit the framing screw 17 to project t erethrough.v And the door may alsofhave anangular opening 18 in its upper portion for the assage of the pin 19-0f t e fire shutter mec anism. This fire shutter is indicated atj20, and it is conveniently supported by being plvoted in the bushing 21 carriedeither. by the door or by a fire shield 22 which is secured to the door. The fire shield may be secured to the door by screws 23 or other'suitable fastening means, and is. as shown, preferably mounted in spaced relation with respect, to the door so asto provide an air space between the frame of the machine The upper and lower pivots or hinges of the door are preferably,- as indicated in Fig. 2, arranged slightly out of vertical alinement, the lower one being'ofiset outwardly fromthe upper one, as in, the nature of a gate hinge so that the door will have a natural bias or tendency to swing closed. A spring catch 26 or like securingdevice may be provided for securingthe door in its closed position',and a stop 27 may be used for limiting the opening movement of the door.

In preparing the machine for operation, the door'is swung open and the entire film moving mechanism is thereby exposed. The film is then readily threaded through the machine, my invention not hindering at all. in this process.- With the door closed, the

film is protectedabsolutely in its entire passage through the machine, thereby eliminating all danger of fire or other injury to the film. By combining the-film support and the film receiver with the'machine, the film is protected during its entire passage from the sup ort to the receiver.

T e stop 27 described above is preferably so disposed that when the door is swung open to its fullest extent,the angular side portion 2 will form a shield in line with the beam of 1i ht issuing from the lantern or other source 0 illumination; This lantern is illustrated more or less diagrammatically'at 28 in Fig. 1, from which it will be readily seen that the film engaged in the film moving mechanism will be protected from the heat of the. lantern even when the door is open.

Inasmuch as in every moving picture machine the film moving mechanism is protected more .or less by the frame of the machine, it will be evident that practically all the advantages of the invention may be obtained by using a shield inclosing only the exposed portion of "the film moving mechanism, instead of a casing completely surrounding the mechanism. 'Accordin 1y I have shown in Figs. 4'and 5 an embodiment illustrating this phase of the invention. Here there is shown combined with a moving picture machine of preferred type, a shield 0r shielding element 29 pivotally mounted on a support 30 so as to swing on a substantially vertical axis in the nature of the door illustrated in the'other views. This shield is in. fact practically the'equivalent of the door to the fireproof casing, since, like the door,

it is preferably providedwith angularly disposed side and rear wall portions 31 and 32 respectively, to cover the exposed side and .rear portions of the film moving mechanism.

The method of mountingthe door may vary but preferably it is arranged to swing on a substantially vertical axis, with the upper and lower pintles 33, 34 offset slightly with respect to each other, as shown in Fig. 5, so as to create a natural bias toward the closed or operative position. And instead of being mounted on a separate support 30, the door or shield may be hinged direct to the frame 35. of the machine. The shield constructed in this manner is in the nature of a door cooperating with the frame of the machine to inclose thefilm moving mechanism. With the shield in normal operativeposition', the film moving mechanismis protected both at the rear and at the side, and when the shield is swung back, the side portion. 31 of the shield is preferably so disposed as to inter.- cept the light from the lantern or other sourceof illumination. I

- The moving picture machine may of course be operated manually or by power. It'is customary to operate these machines by hand. Accordingly I have .showna crank for operating the same. This crank during'its revolution swings in an are past the side of the machine, and hence across the face of the door or shield when the same is closed. In order to prevent :the handle dining or obliquely disposed shank, portion 37, thereby carrying the handle 38 of the crank beyond the socket 39 of the crank to such an extent that no matter what the position of the crank may be, the handle or the shank of the crank will always lie outside the arc described by the opening movement of the door or shield. This feature of noninterference between thecrank and the door or shield is clearl illustrated in Fig. 4.

What is claime is:

1. In a movin picture machine, a frame embodying relatively fixedside and front walls, film moving mechanism supported on the fixed side wall and a door pivoted to the fixed side wall embodying a rear and a side wall tocooperate with the fixed sidefand front wall to constitute a closed casing. 2. In a moving picture machine, a frame front andside portions. respectively of the frame, to form incombination therewith a substantially rectangular fireproof casin'g for'the'film. moving mechanism, said door having an opening or openings therein to lso.

'moving. mechanism and embodyin permit projection of certain parts of the mechanism. p

3. The combination with a moving picture machine having suitable film moving mechanism, of a casing inclosing the film relatively fixed angularly disposed si e and front portions, together with an angular door pivoted to the relatively fixed side portion and cooperating with the relatively fixed side and front portions to constitute an inclosing casing.

4. The combination with a moving picture machine having suitable film moving mechanism, of a pivoted shielding element arranged to protect said film moving mechanism, the said shielding element bein mounted to swing on a substantially vertical axis and having an lar side Walls to cover different sides of te filmmoving mechanlsxn.

5. In combination with a moving picture machine having suitable film moving mechanism, and a lantern disposed in operative relation to the film moving mechanism, a pivotally mounted shielding element arranged to swing on a substantially vertical axis havin angular side portions to cover different sides of the film moving mechanism, and means limiting the opening movement of the shielding e ement to a position where one of the angular side portions of the same will be interposed between the lantern and the film moving mechanism.

Signed at New York city, in the county of New York and State of New York, this 26th day of December, A. D. 1911.
