To all whom it may concern:
1 Be it known that I, CALVIN H. SKEEN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Serving Apparatus, of which the following is a specification.
This invention relates to serving apparatus and consists in general of a drum carrying a plurality of advertisement mounted in a suitable casing.
In the lower part of said casing is mounted a towel and soap dispensing machine, the operation of which is made to actuate a device for displaying advertisement one after the other before a suitable aperture in the front of the casing. u
The principal object of my invention is to provide a new and novel mechanism, which by serving towels and soap will cause a change in advertisements displayed and thus from the fees for advertisements pay for the soap and towels which are distributed free.
Another object of my invention is to makethe casing dustproof and so keep the contents in a sanitary condition until used. Further objects are to provide mechanisms, which will allow but one towel and a measured'amount of soap to be dispensed with one movement of their respective opera-ting mechanisms.
With these andother objects in view my invention consists in the new and novel construction and arrangement of parts as herein described and as more particularly pointed out in the appended claims.
For a full comprehension of the invention reference should be had to the accompanying. drawing forming a part of this specification wherein,
Figure l is a View in front elevation of the improved device constructed in accordance with my invention showing the aperture for displaying the advertisement, the operating rods for soap and towel, and the discharge openings therefor.

Specification of Letters Patent.
Patented Dec. 1, 19171.
Application filed January 31, 1914. Serial No. 815,636.
Fig. 4 is a view in section through the side of the case showing the operating mechanism in elevation. 1 Fig. 5 is a view in section on 55 Fig. 3. Fig. 6 is a view in section on G6 Fig. 3. Fig. 7 is an enlarged fragmentary sectional view on 7-7 Fig. 1.
Denoting corresponding parts by the same numerals of reference, 1 is the outer casing made of any suitable material and having in the front thereof a door 2 held in position by a back 3. An aperture 4: is located nearthe top of this casing having a glass closure 5 through which the advertisements 7 mounted on drum 6 may be viewed.
Standards 8 and 8 have journaled therein a shaft 9 on which the drum 6 is keyed.
On the outside of standard 8 a ratchet wheel 10 is keyed to this shaft and a bell-crank 11 pivotally mounted thereon. The latter comprises; arm 11 having pivotally mounted on the end thereof a pawl 12 adapted to engage the ratchet wheel, an arm 18 carrying a suitable counterweight and having pivotally attached thereto a bifurcated hollow cylindrical member lt.
Sliding within the latter is the end of an operating rod 15 on which is fixed a collar 16 and abutting between this collar and the lower end of sleeve 14 is a compression spring 17.
Formed in theside of standard 8 is a laterally extending pocket 18 in which is slidably mounted a pin 19 having an en larged end 20. A compression spring abutting between the enlarged head 20 and the inside face of the pocket holds the rounded end of the head in contact with the side of drum 6.
Formed in the side flanges of the drum are a plurality of pockets 22 into which the head 20 is adapted to fit and these pockets are spaced at the same angle as occupied by the advertisement 7 thus causing the drum to stop in such a position that the complete advertisement is displayed.
A roller 24 is pivotally mounted in a downwardly extending open slot 25 and mounted on this roller is a roll of paper towels 26, the outer end of which is threaded between rollers 27 and 28. The former is provided with a shaft 30, which is vertition. The arm is provided with a pin 38,
which extends into a slot 37 in the link 37, which is also provided with an elongated head 40 adapted to contact with a pin 41 in the arm 42 of a bellcrank pivotally mount ed as at 41. The other arm 43 of this bellcrank is pivotally connectedv to the lower end of rod 15 previously described.
The end of arm 42 is provided with an are shaped extension 44, which is curved to contact with a curved member 46 on the 0pposite side of gear 33, and disengage the latter from the stop member. Said stop member comprises a spring latch 15, formed on the vertically disposed spring latch 47, which on the lower end is fastened to a lever arm 48, which in turn is keyed to a shaft 49. This shaft is pivotally mounted in standards 8 and 8 and therebetween has attached two lever arms 50 to the outer ends of which is pivotally attached link member 51.
The upper end of the latter are pivotally attached to suitable lugs formed on the lower edge of the cutting knife 52, which is slidably mounted in suitable guides. Back of the knife are suitable guides 53 and 54 adapted to feed the paper toward the dis charge opening 55.
The mechanism above described is operated by a push rod 60 slidably mounted in a guide bracket 61 and pivotally connected on the inside of the casing with link 37 To keep sutlicient tension on the roll 26 I providea weight 62 having. pins 63 projecting from each end into a vertical slot 64, which allows it to follow the roll as it decreases in diameter. To hold weight 62 while a new roll is being inserted, this slot is provided with an angular extension 65 in which the pins 63 may rest.
The soap used with my device is in liquid form. and contained in a tank 66 located between the standards and communicates through an opening 67 with a measuring cylinder 68. Slidably mounted in the latter is a piston 69 adapted as it moves forward to inclose a given amount of liquid in the front of the cylinder discharging the same through tube 70 into the funnel 71 and then through tube 72 to the discharge nozzle 73.
Piston 69 is mounted 011 rod 74, which is connected to one end of a lever 75 pivotally The operation of this device is as follows :rod 78 being pushed inwardly, piston- 68 will be moved forward, discharging the contents of the forward end of the cylinder through tube 70 into funnel 71-where it discharges by, gravity throughspout 73. The object of providing a funnel is to prevent a constant drip as would be the case with a continuous tube.
This movement through pin 80 and lever 81 causes the rotation ofv shaft 41, which through arm 43 moves upward the-rod l5. Tl11S oscillates arms 11 and 13 causing pawl 12 to engage ratchet 10 and move drum 6 around the space of one advertisement or from one pocket 22 to the next.
The object of Spring 17 between the rods 14 and 15 is that a considerable force is required to start the drum duetopin 19 engaging the depression .22 but after it leaves the pin the compression .of the. spring will act to turn the same by the amount lost duringthe compression of the spring. Then when the. next pocket 22 is reached the pin will retain the wheel though the rod may be further moved as such movement unless too great will be taken up by the spring 17.
The inward movement of rod 60 first causes the curved end of 44 to contact with 46 and then. to move the latter from .under catch 45. When this is accomplished the other. end of slot 37 picks up pin 38 and tates wheels 33 and the latter wheel 32. This rotates roller 28 which is rubber faced and roller 27 is of 'heavymaterial so that the paper is carried forward between. these rollers. Vhen 46 is released'from catch 45 the weight of arm 50 link 51 and. knife. .52 causes these parts to drop thus opening slot 55 so that the'towel may be discharged been discharged to enable it to be grasped.
by the fingers. The protruding end ofthe paper is in this manner pulled out and, the frictional contact of the web on the roller 28 causes the latter to rotate, driving gears 32.
The latter in turn drives gear 33 as previe.
ously described, the initial movement ofrod 6O releasing member 46 onthe upperend of arm 47 from the catch 45, thus gear 33 is free to turn when the paper is pulled out, and when 60 is released to grasp the paper, the arm 44 moves to the left releasing end l6 and allowing the upper end of the arm 47 to move toward the face of gear 33 and contact therewith, then when the web has been pulled out a predetermined distance, catch 45 engages the upper end of arm 47, lever 48 is carried down, due tothe further rotation of gear 33. This rotates shaft 49 in a clock wise direction raising arms 50, causing the knife 52 to cut oif the length of towel which has been drawn through slot 55.
It will be observed that the knife remains in its uppermost position until the next operation of the device thus closing all openings and making an entirely dust proof and sanitary device. 7
