MACHINE FOR DEPOSITING A VISCID MATERIAL IN CONTROLLED AMOUNTS Filed Feb. 5, 1953 4 Sheets-Sheet 4 Inventor Willi-1m Ed wu-J Egu-L n H 2,724,336 Patented Nov. 22, 1955 FOR DEPOSITING A VISCID MATERIAL I CONTROLLED AMOUNTS MACHINE This invention relates to a machinefor depositing a viscid material in controlled amounts and more especially to a machine which may be used either for depositing cake batter, sponge mixing, meringue or any similar type of material upon baking tins, prior to bak: ing, or for depositing; synthetic cream, butter brearn, icing, jam or similar viscid types of material upon cakes or biscuits. i i i The commonly practical methodof depositing viscid material upon baking tins or cakes involves the use of a Savoy bag. Viscid material, contained in a fabric bag is extruded in the required amount, through a nozzle at the lower end thereof by means of pressure applied to the sides of the bag. In order tocontrol the amount of material deposited from the bag, very considerable skill is required on the part of the operator.
1 An object of this invention is to provide a depositing machine capable of depositing a viscid material in efficiently controlledamounts in a manner substantially independent of the degree of, skill of the operator.
According tothe present invention, a ma chine for depositing a viscid material in controlled amounts coinprises a delivery vessel, of a capacity substantially equivalent to the amount of material to be deposited, a valve or valves controlling communication between said ,de-
livery vessel and a reservoir for viscid material, and be tween said delivery vessel and a discharge pipe, a pump whereby viscid material is transferred from said reservoir to said delivery vessel and discharged from said delivery vessel via said discharge pipe, and means for synchronizing the operation of said pump with the openingand closing of said valve or valves. p 1
In one form of the invention, the discharge pipe is provided, at the end thereof remote from the delivery vessel, with an additional valve, the opening and closing of which is synchronized with the operation of the pump.
in another form of the invention the depositing machine is providedwith a flexible discharge pipe capable of being guided by the hand of an operator.
In the preferred form of the invention, the delivery vessel consists of a hollow cylinder in which a pump piston is slidably engaged.
The hollow cylinder may be provided at one end with a two-way rotary valve, in one position of which the cylinder is in communication with the reservoir, and in the other position, with the discharge pipe.
Reciprocation of the pistonwithin the hollow cylinder may be effected by a prime mover which also operates the two-way rotary valve. Rotation of the valve to bring cylinder and reservoir into communication is effected when the piston reaches a position adjacent the valve, while cylinder and discharge pipe are brought into com- .pipe to receive its quota of viscid material.
munication when the piston reaches a position remote from the valve. Compared with the gradual movement of the piston, the rotation of the valve is efiected in-.
stantaneously.
An additional rotary valve may be disposed at the free end or ends of the discharge pipe remote from the cylinder and controlled by a pair of flexible cables from the aforementioned two-way rotary valve. 1 One of these cables is provided for the purpose of opening the additional rotary valve; the other for closing it. Alternatively the remote end of the discharge pipe may be provided with a spring loaded valve operated by a single cable. Whether a spring loaded valve or an additional rotary valve is used, it is open only when the cylinder and discharge pipe are in communication.
In operation, viscid material is drawn into the cylinder from the reservoir by means of the suction stroke of the piston when the piston is receding from the valve. This material is. then forced through the. discharge pipe by means of the discharge stroke of the piston. The amount of material discharge depends on the length of the discharge stroke of the piston and means may be provided for varying this length.
If a rigid discharge pipe is used, each tin or cake must .be .moved under the free end of the discharge With a flexible discharge pipe however, the free end of the pipe may be moved over each tin or cake prior to deposition of material.
The provision of a valve at the free end of the discharge pipe reduces the time which would otherwise need to be allowed for. the viscid material to drain from the pipe by cutting off the flow of material as soon as the piston has reached the end of its discharge stroke. A valve is particularly applicable in the case of fillings and ,more particularly aerated fillings such as rnarsh mallow and whipped cream which tend] to fell and to drip from the free end of the discharge pipe unless such a valve is provided to eflfect an instantaneous cut-off.
The invention will now be further described with reference to the accompanying drawings in which- Fig. 1 is a plan view partly in section of a machine for depositing a viscid material in controlled amounts.

Fig. 6 is a diagrammatic representation of the machine illustrating the method of operation thereof, and
Fig. 7 is a diagrammatic representation of the solenoid and brake drum leaf assembly shown in Fig. 1.
Referring largely to Figs. 1-3:
An electric motor 1 is supported upon a base plate 2, slidable in grooves 3a of guide bosses 3 and grooves 4a of bosses 4. While bosses 3 are mounted directly upon a machine base 5, bosses 4 are mounted upon an adjusting plate 6, which is slotted at 6a to receive threaded bolts (not shown) projecting upwards from base 5 into threaded engagement with clamping nuts 7. A threaded shaft 8,
having a threaded portion 8a, engages with a threaded bearing 9 and passes through a delivery vessel support 10, which also acts as abearing. Bearing 9 and support 10 are mounted upon base 5. Threaded shaft 8 may be rotate'd by means of a handle 11 on a wheel 12 mounted on one end of the shaft, and carries on'portion 8a an internally threaded sleeve 13 having a dependent stud 14. A link 15, pivoted at 16 to base is slotted at its ends a, 15b to engage with stud 14 and a stud projection 2a on base plate 2, respectively. Rotation of shaft 8 causes a displacement of motor 1 in a direction parallel to a line joining guide bosses 3 (or guide bosses 4).
Motor 1 drives a shaft 17 on which is mounted pulley 18 of a variable pulley assembly 19, supported on base 5. Driving band 20 links pulley 18 with a pulley 21 on shaft 22 of a reduction gear box 23 on base 5. Variable pulley assemblies such as 19 are well known. Displacement of the motor 1 by rotating shaft 8 so as to tighten band 20, causes band 20 to be recessed into a groove (not shown) in pulley 18 thus causing an effective decrease in the diameter of the pulley for driving purposes. At the same time, pulley assembly 19 compensates for the tendency of motor 1 to draw pulley 18 out of alignment with band 20 by maintaining pulley 18 in a constant position relative to pulley 21. Thus by turning handle 11, the
rate at which shaft 22 is rotated, by power supplied by motor 1, may be controlled.
A drum 24 continuous with pulley 21 is surrounded by a brake drum leaf 25, the end 25a of which is attached to a stanchion 26 on base 5. The slackening of the brake drum leaf is achieved in moving the end 251; of theleaf by means of a solenoid 27, on base 5 (see also Fig. 7). A compression spring 28 is provided to restore the brake drum leaf tothe on position when the solenoidis not exerting an attraction on end 25b of the drum leaf.
A common driving shaft 29, driven through reduction gear box 23 by shaft 22, carries a cam 30 and a crank member 31, giving rise to a cam assembly and a crank as-' semblyrespectively, and being rigidly mounted on said shaft.
.xReferring first to the cam assembly cam 30 is disposed partially within a band member 32 which is loosely mounted on shaft 29 which passes through a slot 32a of member 32. "A bar 33, rigidly bolted at 34 to band member 32 is slidable in a bearing 35 mounted on base 5. A rack. bar 36, rigidly bolted at 37 to band member 32 is toothed at 36a to engage with a toothed sprocket 38 ona rotary valve shaft 39.
1 Referring now to the crank assembly, crank member 31 is in the form of an open ended envelope having a gap 31a in one face. The edges'of the gap retain the head 40a of ashank 40 which passes through the gap. A sleeve 41 surrounds shank 40, and, by means of pressure supplied to sleeve 41 by rotating a wing nut 42 threaded onto shank 40, shank 40 may be secured in the desired position within the envelope of crank member 31. Shank40 and sleeve 42 pass through slot 43a of a link 43.
A pump piston 44, pivoted at 45 to link 43, is slidable in a cylindrical delivery vessel 46 on delivery vessel support 10. A valve chamber 47 communicates with delivery vessel 46, a reservoir 147 and a flexible discharge conduit 48 terminating in a nozzle end 48a. A two way rotary barrel valve 49, disposed in valve chamber 47, is mounted on' shaft 39.
A one way rotary barrel valve 50 (see Figs. 4, 5 and 6), in a valve housing 51 disposed at the nozzle end 48a of discharge conduit 48 remote from valve chamber 47, is mounted upon a stub shaft 52, hearing a toothed wheel 53, engaging with toothed rack bars 54, connected by sheathed cables 55 to rack bar 36 and a rack bar 56, en-
gaging with toothed wheel 38. Stub shaft 52 is housed in a bearing 57 attached to valve housing 51.
A handle 58 (Figs. 4, 5 and 6), attached to discharge conduit 48, supports a spring loaded lever 59 which actuates a sheathed cable 60,, which is attached, after passing through a support member 61, on base 5, to a lever 62, pivoted at 6310 member 61. Pivot pins 64, connect lever 62 and member 61 to a microswitch support member 66, actuated by a compression spring 67,
disposed between member 66 and member 61. A microswitch68 on support member 66 is operated by'c'o'ntacting a cam 69 on shaft 39.
A cover 70 (Fig. 3) for the machine is cut away at 70a, 70b to permit passage therefrom of cables 55 and 60 and discharge conduit 48. Discharge conduit 48 may be wire wound as at 71 to provide reinforcement.
In using the machine (see particularly Fig. 6), an operator grips handle 58, and depresses spring loaded lever 59 which actuates cable 60 causing microswitch 68 to be drawn clear of cam 69. In this free position, microswitch 68 starts motor 1 which rotates common driving shaft 29 through reduction gear box 23. At the same instant as motor 1 is started, solenoid 27 is brought into action freeing drum 24 from the encircling grip of brake drum leaf 25, thus permitting rotation of pulley 21 and hence of shaft 29. Rotating cam 30 on shaft 29 imparts a reciprocating motion to rack bar 36. It will be seen from the configuration of cam 30 that the motion imparted to rack 36 will consist of a series of jerks rather than a gradual movement. The motion of rack bar 36 is transmitted by toothed wheel 38 to shaft 39 and two way rotary valve 49, and also by one or other of cables 55 if necessary by way of rack bar 56 to one or other of rack bars 54 which operate one way rotary valve 50 through toothed wheel 53 and shaft 52. Shaft 29 also rotates crank member 31, causing pump piston 44 to reciprocate. The length of the stroke of the piston may be varied by varying the position of shank 40 with respect to shaft 29 using wing nut 42 (see previously). As is indicated in Fig. 6 of the drawings, when piston 44 is receding from valve 49, valve 49 is in a position connecting reservoir 147 and delivery vessel 46 while valve 50 is in a closed position. A charge of viscid material is thus drawn into delivery vessel 46. Similarly when piston 44 is approaching valve 49 valves 49 and 50 are in positions connecting the delivery vessel with the discharge conduit 48 and the nozzle end, and the charge of material is discharged from the machine. In Fig. 6, rotation of shaft 29 should be considered in a clockwise direction.
It is desirable when the operator releases lever 59 to stop the running of motor 1 that shaft 29 ceases to rotate when valve 50 is in the closed position (as in Fig. 6). When lever 59 is released, compression spring 67 forces microswitch 68 towards shaft 39. Shaft 39 must rotate until cam 69 engages with microswitch 68, depressing the latter and simultaneously stopping the running of motor 1 and releasing end 25b of brake drum leaf25 from the attraction'of solenoid 27, when compression spring 28 causes brake drum leaf 25 to grip drum 24. Cam 69 is so positioned on shaft 39, that valve '50 is in the closed position when cam 69 depresses the microswitch 68. The electrical connections between the microswitch and the motor and solenoid are omitted in the drawings since such connections are well known in the electrical art.
