tain new and useful Improvements in .Cap-

ping-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference being had" to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

My present invention has for its object to provide a machine for aflixing or applying caps tobottles, orsimilar receptacles, and it is intended more particularly. to provide an apparatus for screwing ontothe necks of bottles, jars or other containers, screw' threaded caps and as a type of such receptacles reference is made to the well known catsup bottles.

Generally stated, my invention comprehends the transporting or carrying of a bottle, or receptacle, on which a cap has been previously-placed into juxtaposition with a frictional surface which upon being engaged by the cap will effect a relatiye movement between it and its receptacle whereby the 'cap is caused to be twisted on its screw thread until it becomes seated in .the desired position. v

To these and other ends the invention consistsin certain improvements and combina:

tions of parts, all as will be hereinafter more fully described, the novel features being pointed out in the'claims at the end of the specification.

In the drawings: Figure 1 is an end elevation showing'a machine illustrating one embodiment of my present invention; Fig. 2 is a top plan view thereof; Fig. 3 isa horizontal sectional view taken on the line 3 .3 of Fig. 1; Fig. 4 is aside elevation, and Fig.

.5 is a detail view showing the mounting of the cap-rotating rollers.

Sim1lar reference numerals throughout the several figures indicate the same parts.

- for applying screw caps to bottles, and the 'be understood at the outset that hereafter when the term. bottle is used that it is merely employed as a convenient designation for a receptacle or container .irrespective of its size, shape, or the purpose for which it is intended to be used. The caps applied -to thebottles may be of the usual stamped sheet metal form or anypreferred construe tion, being" provided internally with screw thread pro ect1ons cooperating with lugs or screw threads preferably molded on the exterior of the bottle neck.

A machine embodying my invention,

broadly considered, comprises as one element means for transporting abottle and as a second element meansfigictionally engaging the bottle cap during said transporting movement and causing it to be revolved upon'the bottle so that by the action, of the screwv threads on the bottle and cap, the latter will be advanced the desired distance and securely seated. This friction surface maybe movable and the bottle heldagainst rotatlon durlng transportation, or said surface may be stationary and the bottle rotated whileit is being carried from one place 'to In the preferred arrangement of the parts I prefer to hold the bottle against another.

rotary movement and to arrange the frictional cap rotating means so that it will engage opposite sides ofthe cap and apply the pressure, which it is necessary to exert in orderto firmly grip the cap, on opposite sides of the latter, thus automatically serving to center the cap on the bottle neck and to quickly and easily rotate it into the desired position thereon.

Referring now to the illustrations, it will be .seen that the machine comprises a main frame or table A supported on legs or standards a, a, and b, b, the latter being arranged at opposites of the centerflof the table and extending vertically and carrying at their upper ends a top frame B. The

tending transversely above the table is a. 'conveyer belt 1, of any desired length,

In illustrating my present inventionJI- have shown a machine adapted particularly driven at one end by a. pulley 2 on the shaft table A serves as a support for a portion of the conveying devices and on the frame B 3 carrying a driving pulley 4 to which rotary movement is communicated'fr'om anyconvenlent source. ,The conveyer belt is preferably guided'between the vertically extending walls 1 which prevent any lateral movement of the belt and also serve to prevent bottles resting thereon from becoming displaced either before or after the cap- 11o ping operation dueto vibration of the machine or to the movement of the belt itself. The belt is further supported by an underlying plate 1 the latter and the side walls 1 being mounted independently of the table A. Cooperating with the conveyer both for the purpose of positioning the bottles thereon centrally in respect to the capping mechanism and for the purpose of holding the bottles against rotary movement while the caps are being screwed into position, there is arranged above the conveyer two guides spaced apart sufliciently to permit a bottle to be introduced between them, as shown in Fig. 3, and in order to securely hold the bottle without retarding its progress, these guiding, surfaces are made in the form of endless belts 5 and 6 which are carried respectively on the pairs of pulleys 5 5 6 6 rotating on vertical axes as shown, the bearing studs for one ofthe pulleys of each pair, such as 5 and 6", being adjustable to vary the tension of the belts. This maybe accomplished by means of swinging supports 5, 6 which may be clamped in adjusted position by bolts 5 and 6 It is onlynecessary that a bottle should be' gripped momentarily whileits cap is being seated and for this reason the pairs of rollers 5 6* and 5" 6 are separated so that the inner or adjacent surfaces -of the belts 5 and 6 at their forward ends where the bottles enter and at their rear ends, where the bottles are discharged, the space provided is greater than the diameter of the largest portion of the bodies of the bottles. This permits the belts to perform a further function of moving the bottles laterally on the conveyer 1 tov center them in respect to the capping mechanism, and after the latter has performed its operation the bottles are' released immediately. Inorder to cause the belts 5 and 6 to firmly engage the bottles they are each backed by an intermediate roller 5", 6 provided with a thick face formed of rubber or other resilient mate'- rial, as shown in dotted lines in Fig. 3. For the purpose of accommodating bottles having bodies of: diflerent diameters, these backing rollers 5 and 6 are mounted on studs carried on swinging arms-5 and 6 pivoted at one end, as indicated at 5 6 and adjustably secured at their opposite extremities, as shown by thelock nuts 5 and 6 The parts described above are all carried on the table A, with the exception of the conveyer, and the table is adjustably secured on standards a b by the split clamps A whereby the mechanism may be raised or lowered as may be required. to accommodate bottles or receptacles of varying lengths. i

The capping mechanism proper which engages the bottle caps for the purpose of screwing them down on seatingthem on the necks of the bottles is shown, in the present embodiment of my invention, as comprising two frictional surfaces arranged. in the form of rollers C and D spaced so as to engageopposite sides of a bottle cap and each disposed to rotate in a plane arranged at a slight angle to a horizontal plane and substantially parallel to the convolutions of the engaging screw threads of the cap and bottle neck at opposite sides of the latten.v

The capping mechanism is all carried on the top frameB, the rollers C and D being respectively mounted on shafts 0, d carried in bearings C, D provided at their upper ends with yokes C D pivoted to laterally extending ears of bearing plates C D mounted at opposite sides" of the depending bracket B to which latter said bearing plates are secured in the angular position shown in Fig. 5 for the purpose of supporting the rollers G, D in the desired position of angular adjustment. The pivotal. mounting of the bearing sleeves C, D permits toward each other is limited by the adjustable stop bolts 0, d carriedonthe sleeves C, D and engaging the sides of the bracket B.

Rotary motion is imparted to the rollers C and D, in the direction indicated by the arrows in Fig. 3, so that when a bottle .cap is engaged between them it will be driven in a direction to advance it along its thread'the required distance to seat it on the neck of the bottle with the desired firmness. This is accomplished while a bottle is being transported between said rollers by the combined action of the conveyer 1 and the holding belts 5 and 6. By reason of the fact that the roller D at the point where its surface engages a bottle cap, is moving in the direction of the conveyer 1 it is desirable thatthis roll be driven at a slightly increased rate of travel in comparison with the speed of rotationv ofthe roller C. The cap rotating rollers C and D are driven by the pinion C", D mounted on short shafts, journaled in a frame B. which are connected with their respective shafts c and d by universal joints, one of which is shown -in Fig. 5 andindicated. by C The driving gears of the pulley B and through the table- A where a pair of beveled pinions 14 connect said shaft to the countershaft-15, carried in a on the. bottle.

bearings on the lower face of the table A. Another pair of bevel gears 1 1 transmit rotary movement from the shaft 15 to -the shaft 14 which drives the pulley 5. countershaft 15 is driven from the shaft 3 by the sprocket chain 16 carried "on the sprocket wheels 17 and 18.

' The frame B and the cap seating mechavertically I provide on each of the standards, between the clamps B and stationary collars b, rotatable JCOllaI'S b the engaging ends of whichare provided with inclined cam surfaces whereby when one collar is rotated on the other they will be separated and the frame B elevated.

In the operation of the machine the bottles, or receptacles, after being filled and sealedhave' their caps placed loosely on the bottle necks, after which they are delivered, by hand or otherwise, to the conveyer belt 1. The bottles are received on the conveyer spaced apart a short distance, and as the conveyer is moving continuously each bottle is in turn brought into the opening between the entrance ends of the belts 5 and 6 and by one or the other of these each bottle is adjusted laterally into central position and is soon firmly gripped between said belts and held againstrotationduring its travel in a lineal direction covering a space of several inches. While a bottle is thus held it, is

being transported and its capv engages and forces apart the rollers C and D. These rollers are traveling at differential speeds, but at such speeds relatively to the movement which is being imparted to the bottle itself that during the brief. period in which said rollers are permittedn to engage the cap the latter is driven the required number of revolutions, or partial revolutions, as the case may be, and caused to be firmly seated The capping mechanism embodying my invention consists of few parts which are The e the structure I "have shown as a practical embodiment of my inventionmay be made without departing from the spirit of the invention as definedifi' the appended claims.
