3 Claims.

This is a division of my pending application for patent on a Labeling machine, filed August 11, 1936, Serial No. 95,371.

The principal objects of this invention are to provide for the discharge of the bottles to the delivery table radially with respect to the labeling machine and complete the wiping during that radial motion; to provide a final wiping operation of the neck and body labels comprising r0- tary wipers, the surface of which can move along with the label; to provide an improved discharge bottle pusher, and to provide rollers'for holding -the bottles after the operation of the rotary wipers.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. l is a plan of a labeling machine showing a preferred embodiment of this invention;

Fig. 2 is a plan of the delivery of the labeling machine;

Fig. 3 is an elevation of the same looking in the direction of the arrow 3 in Fig. 2, and

Fig. 4 is a sectional View on the line 4-4 of Fig. 1 of a part of the steadying roller slide.

The machine is provided with the usual features to indicate how they are related to the main labeling mechanism. The rotary bottle carrier I3 and the bottle support I9 operate to rotate the bottles intermittently. They bring the previously labeled bottles, or the like, to the position shown in Fig. 1 and stop.

From a cam, not shown, a lever 20 is operated. This lever, through an adjustable link 2|, operates a slide 22 which carries on it a discharge pusher 23. This pusher has a head which engages the bottle and, when it is moved outwardly radially, it will push the bottle off the carrier I3 on the discharge conveyor I6.

From a cam, not shown, is operated a lever 24 which, through an adjustable link 25, operates a slide 26. This slide carries a pin 2l which, through rolls I2, operates two bell cranks 28 which have arms which are connected by a spring 29. On the shafts I0 carrying the bell cranks 28 are supported two arms 30. The shafts I0 of the bell cranks are supported on the frame II of the machine. On these arms 30 are fixed two v bases 33 which carry a pair of soft rubber surfaced rolls 34, preferably sponge rubber. On an upward extension 35 a pair of similar rolls 36 are carried.

On a pair ofy brackets 3l pivoted'at 38 and having arms extending upwardly, which are normally held together by springs 39, are carried a' pair of wiper arms 40. These arms are provided with bases 4I on the top carrying vertical rods 42 on which are freely and rotatably mounted wipers 43. Also an extension 44 projects upward- Ii ly and carries a neck Wiper 45.

Therefore, when the pusher 23 is pushed forward it will carry the bottle, as stated, not only off the carrier I3--I9 but through the two wipers 43 which are merely pulled toward each other by means of the spring 39. These are to further lay down the labels and as the bottle goes further itis engaged by the two steadying rollers 34 to hold the bottle against jumping forward from the pressure of the wipers 43 forced inwardly by the spring 39. The bottles are then freed from this machine and move along the conveyor IB to the delivery table, not shown.

A bottle which has been labeled is then moved around intermittently with the other bottles until it comes to the position shown in Fig. 2 where it is pushed out by the discharge pusher. The bottle then passes in a radial manner outwardly first through a pair of soft wiper rolls 43 for operating on opposite sides of the body label, each of which rolls has attached to it a soft neck label wiper roll 45. These are spring-controlled and the bottle has to pass through them with a consequent rolling wiping down of the labels on the bottle and neck. Just after the bottle reaches these roll label wipers it would be pushed forward by them suddenly, but it comes in contact with the steadying rollers and neck steadying rolls 36. All these rollers thus described are made of sponge rubber, preferably, and they are all in rolling contact with the label so that they move with the label and cannot put any resistance against the label or any force to tend to move the label backwardly on the bottle.

It will be seen that by the use of this invention the rotary table for supporting the bottles while they are being labeled is made smaller than is usually the case. With its tangential discharge conveyor it occupies less space than has been the case heretofore. This special arrangement renders the machine readily adaptable to the placing of a battery of machines close to each other to be fed by one conveyor. The bottles are discharged through a radial carrier and, having been wipedby a pressure wiping on the machine itself, they are wiped by a pair of sponge rubber wipers applied at the neck and body simultaneously, operating when the bottle enters a certain place. As the bottle leaves these wipers, it is steadied by the

rolls

34 and 36.

These latter wipers move about their axes with the labels.

Having thus described my invention and the advantages thereof, I do not Wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

l. In a labeling machine, the combination of a circular path for the articles to be labeled, means for discharging said articles radially at one point, means for performing the nal Wiping operation of both neck and body labels during said radial motion of the article being labeled comprising neck and body rotary Wipers, the surfaces of which are capable of moving along with the respective articles With labels thereon, and rollers in position for engaging and holding the labeled articles after they have been operated upon by said Wipers.

2. In a labeling machine, the combination of a slide, a pair of bell cranks pivotally and loosely connected with said slide and extending in opposite directions therefrom, and a pair of wipers connected with the bell cranks to be operated thereby and located on opposite sides of the article to be labeled, each one comprising a cylindrical body Wiper and a circular neck wiper xed with respect to the body wiper, each composed of sponge rubber and the neck Wiper being offset from the body Wiper for engaging the article and finally wiping down the neckand body labels respectively, and means for yieldingly holding the Wipers against the article labeled.

3. In a labeling' machine, the combination of a pair of Wipers, each one comprising a cylindrical sponge rubber body Wiper and a circular sponge rubber neck Wiper offset from the body wiper and beyond its end for engaging the article and finally simultaneously wiping down the neck and body labels respectively, yielding means for causing the wipers to press against the article to be labeled, and a pair of soit rubber rollers in position for engaging and receiving the labeled article from the wipers.
