E. BUL.L|S El' L s'raI'xING BAG STAND' Afin ATTACHMENT Jan. 9, 1940.

--Fnqd April s. 1937 Vfl Patented Jan. 9, 1940 n UNITED." STATES ,2M-2403 ff STRIKINGBAG STAND ,iiNn-ATTACHMNTQ f Earl Bullis',Amsterdam, 'N.'Y., land` I Stechvler, Chicago, Ill.' v Application April s, 1937, seria-iNo. 1.343,91a; 7 ciaimskg, (o1. k2v2-'18) I This invention relates toan improved striking bag which .may be either of the type suspended from an overhead support or of the floor type in which case `the bag is supported upon the upper en'd'of a staff rising from a hoor-engaging base and yieldably maintained in a verticalf position.

One objectA of the invention is to provide bag With improved means for connecting itwith either, the overhead support or the upper"V end of the staff and to so form the mounting means that, when the bag is in use, transverse strainl created by hitting the bag will be distributed over a large area and thus prevent the bag from 'being torn loose from the support ordistorted out of a. positionpin axial alinement with the staif in case the bag is connected with a support of the floor type instead of being suspended froman overhead support.

It has'been found-that, when a striking bag i is supported in a conventional manner and blows delivered upon the bag which tend to imparta turning or spinning movement to it, this turn-4v ing `movement will weakenthe support yand cause bagesuspending strapsy to be broken.

' `1t is, therefore, another object of the inven-v tion to provide a support which will permit the bag to turn freely about a metal rod or bolt forming part of the support and thus eliminate l' -elements which are liable to be weakened and broken by twisting'motion when the bag is in use.

Another object of the inventiony is the provision of a support so constructed that it may be' ,mounted in ythe smaller end of the leather or fabric cover of a punching bag with the tapered portion of the bladder of the punching bag fltting snugly kinto a cup-shaped portion of the support. By this arrangement of parts `pressure will be exerted when thebladder is niiated and the cup-shaped portion of the support which fits within the cover Willbe rmly held in place.

It is another object of the invention to sok formthe cup-shaped portion 'of the attachment .45

that, when it is disposed Within the cover ofthe punching bag* and the bladder inflated, the external appearance ofthe bag Will 'notbefchanged and, therefore, the bag will havea conventional outlineand a person using the striking bag will not have to become accustomed to' a new type of bag. y

Another object of the inventonfis to provide an improved type of staff or supporting rod for al ,striking bag and so form the same that its lower portion willloe,l resilient. :and thusv maintain the4 the usual manner.

the coverfrom the valve 2 is tapered to provide la conventional construction. l

In Figures 1 and 2,l the striking bag has been 50 shown` connected with a support of the floor the rod orstafinormally'inaperpendicular position while atv the Sametime allowing the staff 'or rody to swingytransversely when theI bag is struck,k

bladder,

`Figure "I` is a sectional View of an overhead support constructed in accordance with this invention:

'li'he punching bag or striking bag, which is 35.- indicatedin generality the numeral I, is of a conventional construction and provided ,with rthe usual inilating valve` Zso that lthe bladder 3 which fits'within the cover 4 may be inflated in The opposite end portion of il);y

the usual neck 5 into Which the tapered end 3al of the .bladder extends. It will thus beseen that no Ychanges have-been` made in the formation of the cover or vthe bladder and/that the improved 45Vy attaching means `for connecting the striking bag a with van overheadsupport or a support 4,of the, iloortypemay be applied to a striking bag of type, .but attentionA is called to the fact that the attaching means is of -a special construction and yalso the support is `cfa new and improved formation; yThe .attaching .'member, which' is indi 551;,

cated by the numeral 6, has a cup-shaped body formed of rubber and the walls are gradually reduced in thickness to a feathered edge at the free marginal edge of the cup so that,fwhen the attaching member is placed within the cover withits neck enclosed by the neck of the cover, the cup-shaped body of the attaching device will t snugly between the cover and the tapered end portion 3a of the bladder. fit between the attaching device and the striking bag, and it should also be noted that since the tapered end of the bladder lits snugly within the cup-shaped body oi the attaching device pressure is exerted when the bladder is inilated and will cause a tight wedgingflt -between the attaching device and the neck of the cover, and the attaching device will be firmly held in place. The fact that the attaching device ts snugly within the tapered end portion of the cover about the tapered end portion of the bladder will cause transverse strains created when the bag is struck to be distributed over a large area of the tapered end portion of the bag and likelihood of the bag being torn loose from its support will be eliminated. A metal bushing or core 8 extends through the neck 'l axially thereof and is formed with` external circumferentially extending ribs 9 in order that the metalcore will be prevented from slipping longitudinallyv through the neck and moving out of its ,proper position therein. The inner end portion of the bore of the tube is of an increased diameter, thus providing the tube or core with a socket i8 at its inner end, and this socket is open at both ends in order that the attaching member may be operatively connected with a support which maybe ofthe floor type or the overhead type. Frictional binding between the core andthe -rubber may be depended upon for removably holding the core in the neck or cement may be used to cause them to adhere to each other.

The oor type support includes the usual platform Il which may be formed of wood or other desired material and may be of circular outline or any other desired shape. The base l2 of the support which may be referred toas a mounting bracket is formed of strong metal and is provided with radiating feet i3 through which screws Lor equivalent fasteners M are passed to hold the base iirmly in place at the center of the platform. Openings l5 are formed through the feet to receive the screws, as shown in Figure 2. Ribs I6 which are formed at the junction of the feet with the base reinforce the feet and base and prevent them from being broken whensubjected to strain. A neck ll extends upwardly from the base and is externally n threaded so that it may have threaded engagement with the convolution of a helical spring i8 provided yat the lower end of a rod or standard i9. This spring has its convolutions closely wound so, that they have contacting engagement with each other and provide a helical spring of the type known as an initial tension spring. The fact that the convolutions ofthe spring have contact with each other causes them to resist transverse flexing of the spring and, therefore, when the spring is exed transversely by the force of a blow delivered upon the striking bag, the resiliency of the spring will return it to a vertical position and transverse distortion of the spring will be prevented. Attention is also called to the fact that, as initially formed, the spring has an internal diameter 'slightly less thanv the4 diameter of thej neck.

75 Therefore, when, the .spring `is screwed into Aplace This provides a goodv dimensions adapting it to be snugly received in the socket l0. Since the socket and the head are of cylindrical formation, the metal insert or core 8 may turn about the standard in case it is desired to permit this action to take place. A

'disk 20 is secured in the upper end of the core for limiting upward movement of the rod through the core and preventing the head 2u from puncturing the lower end of the bladder If it is desired :to prevent turning of the attaching device about the rod, a set screw may be passed through the core with its inner end engaging the rod.

When a striking bag mount, as shown in Figures 1 and 2, is in use, it will'be supported in any upright position. When the bag is struck, it will be impelled transversely and the rod will be swung laterally. The fact that the core extends along the rod for quite a distance prevents the strain from being applied to the rod at the extreme upper end thereof, and since the attaching device is confined in the cover of the bag and encloses the tapered lower portion of the bladder will cause strain to be distributed over a relatively large area ofthe lower portion of the bag. Therefore, the bag and the rod will move together as a unit instead of the bag being tilted at its junction with the rod and the bag will not be liable to be distorted laterally or broken loose from the upper end of the rod. In view of the fact that the closely wound convolutions of the spring serve to resist transverse bending of the spring, the spring willy at all times return to a vertical position after a blow has been struck and lateral distortion of the spring will be prevented.

In Figures 5 and 6, there have been shown modified forms of attaching members for connecting the bag with the upper end of the rod or standard. Referring to Figure 5, it will be seen that a metal bushing or core 23 is mounted in the neck of the carrier but this core terminates in spaced relation to the upper end of the neck instead of extending entirely through it and is closed at its upper end in order that, when the upperend portion, of the resilient rod l@ is thrust into this core, its upward movement therein will be limited and the attachingdevice will be well supported upon the rod.Y In using this formlof neck `in alinement with the threaded opening 25 to receive a screw driver and permit the set screw to be tightened or loosened. The attaching device shown in Figure 6 also has a metal bushing or core 28 having a thickened lower portion 29 formedwith a threaded opening to receive a set screw V30 in order that therattachingdevice'may shaped portion 6 of the attaching device iitting about the cover of the'bag, and, when the screw 30' is passed through the opening. formedat the J vbermly secured uponthe upper end portion of the resilient rod or standard I9.Y The upperend portion of the core or insert is exposed through the upper endv of the neckcentrally of thecup 6 and threaded to receive a securing screw 3Wv which passes through a cup-shaped clamping disk 3|. When this embodiment of the invention n is in use, theattaching device may be disposed ,about the lower end portion of the striking bag' instead of fitting within the cover about the bladder. The cup-shaped disk 3| fits within 'the tapered lowerend of the cover with the cupcenter of the disk and screwed into the internally threadedA upper end portionof the core 28, the

' bag` will be `very'rmly heldin place. as the lower portion of' its cover ywill vbe tightly gripped between 'the cup-shaped disk and the cup-shaped portion of the attaching device. Referring to Figure 7, Vit will be seen that the attaching device may be 'connected with an over- `headsupport instead of with a standard or ref silient rod forming -part of a iloor support. The

attaching device illustrated in-Figure 'l is of the same construction as that shown in Figure 2,

` and will be mounted in the lower tapered `end A. portionof thecover vofthe bag where itA will be -iirmly held when the bladder is inflated. A metal shackle 32, corresponding in diameter to ythe resilient rod I9,v extends through the bore of the core or bushing '8 and at its lower end isformedwith a head 33`received in the socket Il) of thev core. A disk 33' is provided. to prevent the head 33 from puncturing the bladder. At its upper end the shackle'is formed with an

eye

3,4 which isdisposed externally of the core yabove the upper end thereof and this eye loosely engaged with` the eye of the eye-bolt 35. 'I'he threaded shank of the eye-bolt is of sufficient length to permit it tobe passed throughan open- -ing formed in an 4overhead support 36 and carries washers 3l and securingnuts 38 which are applied, as shown in Figure 7, so that, when the securing nuts-are tightened,the eye-bolt will be v eryrmly mounted through the opening in the yoverhead support. In View of the fact that the vstem of the shackle 32 and its head 33 are of circular cross section, the attaching `device may v turn about the shackle and, therefore, when spinning motion is imparted tothe ball by aglancing blow, vthe ball may turn about the shackle instead of being subjected 4to twisting'y strain.
