Application August 7, 1939, Serial No. 288,843
This invention relates to bottle washing machines of the type described in the pending application of Philip C. Read, Serial 'No. 257,44 filed February 20, 1939, for Bottle washing machines, and refers particularly .to the bottlecarriersof such machines which are provided with means for gripping the bottles attheir necks.
In the past various methods have been used to grip the bottles by their necks. One of these methods is disclosed in the aforementioned pending application. It employs two spaced superimposed carrier bars provided with aligned holes, through which the headed ends of the bottles project to be secured in place by a locking plate slidable between the carrier bars andprovided with longitudinal keyhole slots to engage the necks ofthe bottles.
Inasmuch as actuation of the sliding .bar was cam controlled, these past types of bottle carriers were objectionable due to unavoidable breakage of the bottles when gripped by the bars. Even the most accurately machined carriers of this pasttype were subject to the same objection, for any inaccuracies were multiplied as a consequence of the large number of, bottles carried by each carrier. j
With'this past objection in mind, the present invention has, as one of its objects, the provision of a yieldable latch or clamp operable to grip the neck of a bottle beneath its enlarged head with spring tension to securely clamp the bottles to the carrier without danger of breakage. v
Another object of this invention is to provide a bottle carrier of the type'described with individually resilient latching members whose resiliency normally maintains them in operative clamping position about the neck of a bottle, and whereby a single locking bolt connected to each of the latching members is operable to simultaneouslyvrelease all of the latches on the carrier.
With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention maybe made as come within the scope of the claims.
The accompanying drawings illustrate several complete examples of the physical embodiment of the invention constructed in accordance with the best modes so far devised for the practical application of the principles thereof, and in which:

Figures 9 and 10 are top plan views of a portion of a bottle carrier illustrating a further modified embodiment of this invention.
Referring now particularly to the accompanying drawings in which like numeralsindicate like parts, the numeral 5 designates a pair-of endless conveyor chains which are joined at spaced interv als by bottle carriers '6. Inthe present, instance, only one such bottle carrier has been shown. r
The bottle carriers comprise'two superimposed bars 1, and 8 held in spaced apart relationship by spacersll at various points along the length of the carrier. At equispaced points along the length of the carrier, the bars land 8 are 'provided with aligned holes Ii] and l l,'respectively, topermit the heads H on the necks of bottles B to pass therethrough. v
To enable the bottles to be gripped at their necks without in anywise endangering the same with regards to breakage, resilient substantially U-shaped wire clamps, indicated generally by the numeral [2, are provided, one adjacent to each set of aligned holes in the carrier bars. The clamping members 12 are positioned between the carrier bars 1 and 8 and have one end portion [3 fixed to the carrier bars as'by weldingor by screws l4.
The 'free end portions E5 of the clamps form a loop of a size to snugly and resiliently engage the neck of a bottle beneath its enlarged head to rigidly clamp the same against the edges of the holes l0 and H of the carrier. I Q
The free end l5 of each of the clamping members I2 is bent laterally so as to extend from thesidesof the carrier bars and have loops 15 formed thereon for engagement with a stop collar l1 secured to a latch bolt l8. The latch bolt I8 is slidable in bearings l9 formed as an integral part of the spacers 9, and extends along the entire length of the carrier bars to project from each end thereof.
As already stated, the yieldable clamping members normally maintain clamping engagement about the neck of a bottle with spring tension; and when it is desired to release the bottles from the carriers, it is only necessary to slide the locking bolt I8 to a position illustrated in Figure 4, which enlarges the loops of the clamping members to a diameter equal to or greater than the size of the holes in the carrier bars.
The customary manner of actuating the locking bar in such a manner is to provide a plate or flange 20 which is engageable by a cam 20 to slide the bar against the spring tension of the yieldable clamping means. H
While in most instances the resiliency of the clamping means is sulficient to maintainthe bottles tightly gripped, an auxiliary spring 2! may be provided, if desired, to further increase the gripping force ofthe clamping members on the bottle necks. I Y
The, spring 2| is located at the end of the locking bar opposite the-flange 20 and is engag ed between a collar 22 at the extreme end of the locking bar and its adjacent bearing 9.
If desired, the stop collar l'l which-secures the free ends I of the clamping members to the locking bolt may be adjustable-on the locking bolts; and to this end, set screws 23 are provided. It is obvious that by adjusting the position of the stop collar l1, thegripping force'of allthe gripping members acting on the bottle necks may be equalized.
The carrier illustrated in the modified embodiment in Figure 5 is similar inthat it employs superimposed locking bars I and 8 held spaced apart by spacers or side walls 9' at various points along its length. Q l
The resilient bottle gripping means 24 of this modification are carrieddirectly by a sliding plate or bar 25 positioned between the carrier bars I and 8. Slots 26 in the bar25'equal in number to the aligned holes in thecarrier bars, permit the necks of the bottles to be properly po sitioned. e l
The clamping members or gripperslfi in this instance are substantially U-shaped and have their free ends secured to the bar 25 at one end of the slots while the opposite closedend of the clamping members extends to the other end of the slot and has a constrictionas at'2l forming a throat to receive and guide the bottle upon sliding of the plate 25.
Such sliding motion of the plate 25 draws the opposite sides of the U-shaped gripping members into engagement with the necks of the bottles in the holes and II, and the resulting spreading of thesides permits an outwardly kinked locking portion 29 of the grippers to grip the neck of the'bottle beneath the head thereof as clearly shown in Figures 6 and 7. An upstanding flange 30 at one end of the bar which projects from the carrier is engageable by a cam 3| duringtravel of the conveyor to effect engagement of the bottles by the resilient gripping means while-a-cam 32 is provided for engagement with the flange 30 to slide the bar inwardly to effect releasing of the bottle gripping means.-
Figures 9 and 10 illustrate a further modifie embodiment of this invention wherein the bottles are gripped at their neck portions by pivoted grippers 33. Each gripper, which is formed as a lever, is adapted to effectively grip two bottles; and to this end, the levers are of a length to extend between two adjacent sets of holes I!) and I I in the carrier bars and are pivoted to the carrier bar by pivot pins 34 passing through the medial portions of the levers.
The opposite ends of each lever have jaws consisting in arcuate slots 35 concentric to the axis of the pivot 34 and of a width to receive the neck of the bottles.
As in the embodiment of the invention shown in Figures 1 to 4, inclusive, a sliding locking bolt 36 may be provided to actuate the levers to inoperative and operative positions. For this purpose, the locking bolt has a plurality of adjustable collars 31 fixed thereto, each carrying a stud 38 which engages in a hole 39 formed in a lug or extension 40 projecting from one side of the adjacent lever. l
Sliding of the locking bolt 36 in one direction by a cam (not shown) disengages the jaws of the levers from the necks of the bottles beneath their enlarged headsas shown in Figure 9; and sliding of the locking bolt, in the oppositedirection by a cam (not shown) engages the jaws about the necks of the bottles tosecurely clamp the same to the carrier, as shown in FigureIO.
Inasmuch as the set screws 41 of the collars 3'! permit accurate adjustment of the throw of the levers when actuated into gripping engagement with the bottle necks, breakage of the bottles may be held at a minimum. J
From the foregoing description taken in connection with the accompanyingdrawings, it will be readilyapparent that this inventionprovides a simple and inexpensive but highly eflicient manner of gripping bottles at their necks which insures against breakage of the bottles during such gripping operation.
