cusl-rronrne ATTACHMENT non runcrrrive MACHINES.
Application filed August 17, 1925.
My invention relates to punching bags and their appurtenances and more particularly relates to what is usually termed the platform or element presenting a down wardly facing surface to receive the impact of the suspended bag when the bag is punched. It is a recognized objection in the use of punching bags that they jar the walls of a room and the jar is evencomniunicated to adjacent rooms and to adjacent floors when theball is struck hard and the impact against the so-called platform is pronounced.
An object of myinvention is to provide in association with a punching bag, a platform or a buffer element ofsuch a character as to largely absorb the shock and furthermore having such a relation to the punching bag that the bag will have impact against the buffer directly adjacent the upper end of the bag so that a greatly lessened shock results. With the ordinary bag and its appurtenances also, the platform employed has such an area as to receive the impact of the point of suspension of the bag so that notonly is the impact very pronounced but the bag must be suspended ina position distant from the'wall or other vertical support in order that the platform may beaccommodated. Accordingly, it is, an object" of my invention to provide a compact assemblage of a punchingbag and suspension means, the compactness being made possible by a buffer or plat form novel in its form and relation to the bag and supporting means.
The nature of my invention and its distinctive features and advantageswill clearly appear as the description proceeds.
eference is to be had to the accompanying drawings forming'a part of this specification, it being understood that the drawings are merely illustrative of examples of the invention.
Figure 1 is a view partly in elevation and partly in vertical section showing the bag suspension means and the bag including a novel buifer for the bag in accordance with my invention;
Figure 2 is a plan view of the bag, its suspension means, and the buifer;
Figure 3 is a fragmentary view in vertical section showing a modified means for suspending the bag;

showing the modified means securing the impact arm to a wall or the like.
The numeral 10 indicates a punching bag of known form suspended from a tubular head 11 on a lateral bracket arm 12 which in the form shown in Figure 1 is received in a socket 13 suitably fastened to an upright support conventionally indicated at 14, the bracketcsystem 12 being shown as threaded into the socket 13. In Figure 4 an unthreaded socket 113 is shown to receive the bracket arm 112, said socket being secured to any suitable support 114%. In said Figure 4 the bracket arm 112 which, like the bracket arm 12 may consist of a short length of tubing, is fastened to a socket 1 13 by a transverse bolt 115 having a nut 215 shown as a wing nut.-
The suspension means for the bag in Figures 1 and 2 consists of a cord 17 fastened to a thong 16 in the upper end of bag 10, said cord passing downwardly through 18 to the under side of the alined holes bracket arm 12 and upwardly through holes 19 in said bra'cke'tarm to form bends 20 in.
the cord, the end of as at 21.
In order to receive on the'bag the cord being knotted the impact of a blow 10 when the latter is punched of the impact and prevent jars inthe suspension means and in the supporting wall, I provide a butter 22 in the form of a disk-like element which is shown as having an upstanding neck 23 entering into the tapered bore of head 11, Said buffer 22 isdisposed directly against the under side of an annular flange 21 on the lower end of tubular head 11. Thus,
the flange 21 rigid with head 11 forms a backing and strengthener for the cushion-- ing buffer 22. The buffer 22is of rubber or equivalent resilient materialand it extends only a short distance radially outward from the upper end of the punching bag 10 instead of as usual in the platform employed being of a diameter greater than the largest diameter of bag 10. Moreover, it is to be noted that the buffer 22 is directly associated with the upper end of the bag and in close relation thereto, the effect of which is that the bag will strike the bufier at a zone of the bag near the upper end thereof, so that the largest part of the bag does not strike the buffer as is done in the case of the platform usually employed.
' of the bag 10 enters and at the construction in 5 holding the bag.
In the form shown in Figure 3, the suspension head 111 on the arm 12 has an internally threaded upper end as at 2 1 and receives a screw plug 25 through which a short rod 26 extends and has a loop 27 at its lower end carrying a hook 28 which is engaged with the thong 16 on bag 10. Said vertical rod 26 is threaded at its upper end and receives a nut 29, usually a wing nut, to vary the tension on the thong 16 and insure the proper position of the bag 10. In said Figure 3 also the buffer 122 corresponding essentially with the buffer 22 has a strong neck 123 into which the upper end upper end of said neck 123 is an annular bead 223 which bears against the flange 121 corresponding with the flange 21 of head 11.
The provision of the neck 12?) gives sub stantial body to the buffer 122 above the radial impact portion thereof and transmits the shock against the flange 121 through the medium of said neck 123. An important result is obtained also by the defined that the arrangement to cause the impact on the bag to be delivered directly adjacent the narrowing tapered upper end of the bag makes possible as it does the use of a buffer or platform of very small radius. The axis of the suspension head and ball maybe located close to the wall or other vertical support, whereby a bracket arm of very short length can be employed. delivering the impact close to the wall the leverage through which the blow of the bag acts is comparatively short and therefore the extent of the jar produced by .the shock is minimized, so that not only is the shaking of walls almost eliminated but there is a very greatly reduced tendency of the bracket arm and its fastening means to become loosened since the strains thereon are materially reduced. It will be observed that no springs or elastic cords are employed in I would state furthermore that while the illustrated examples constitute practical embodiments of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be departure from considerably varied without the spirit of the invention as defined in the appended claims. For example, it will be readily understood that the bag may be mounted in any suitable manner, either suspended or on a standard in accordance with the usual practices.
Having thus described my invention, I claim:
1. In a bag and securing means therefor, a tubular securing head, the bag at its upper end extending into said head, means holding the neck of the bag in said head, and a rubber buffer element extending upwardly into said head and snugly encircling the neck of the bag.
2. A punching bag and securing means therefor including a head, means holding the neck of the bag in the head, and a resilient bufler element disposed in the head and snugly embracing the flexible neck of the bag, said buffer element having a laterally extending portion at all sides thereof defining a horizontal impact edge against which the, portion of the bag near the neck is adapted to strike.
3. A punching bag and securing means therefor, including a head formed with a downwardly presented flaring mouth, a rubber buffer element snugly fitting within the flaring mouth of the head and snugly embracing the neck of the punching bag.
4. A punching bag and securing means therefor, including a head formed with a downwardly presented flaring mouth, a rubber bufler element snugly fitting within the flaring mouth of the head and snugly embracing the neck of the punching bag, said bufler element including a horizontally disposed impact flange extending laterally beyond the head.
5. A punching bag and suspending means therefor including an element having a tubular portion for receiving the upper tapered end of the bag, said element having a flange extending laterally outward at all sides, said flange being resilient and adapted to receive the impact of the bag adjacent that portion of the bag received by said tubular portion of said element.
