THOMAS MCGONNELL, OF NEW KENs-ING'roN, PENNSYLVANTA;
Application filed April 28, 1920. Serial No. 377,298.
To all whom it may concern:
Be it known that I, THoMAs MoCoN- NELL, a citizen of the United States, residing at New Kensington, in the county of VVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Vacuum Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to improvements in vacuum apparatus, and is an improvement on my Patent No. 1,314,409, dated August 26th, 1919.
One object of my present improvement is to create a vacuum in the helmet by both the in and out movements of the pistons, whereby the vacuum pumping action is made double acting and creates a substantially continuous suction action within the helmet, instead of having the pistons with a suction action in one direction only, as in my aforesaid patent.
Another object of my present invention is to provide the apparatus with means for controlling the amount of power necessary to move the pistons, whereby the operator can control the degree of exercise required for operating the apparatus, and whereby the apparatus has a two-in-one function of developing a healthy body through physical exercise and to treat the scalp by suction action for inducing the growth ofthehair on the scalp.
Another object of my present invention is to so construct the means for controlling the physical exercise that its adjustment is indicated upon a dial, whereby the user may from day to day increase the strength required to operate the pistons to keep pace with the muscular development of the user, and to enable the user to determine' in pounds thepul]. required for operating the ap aratus.
nother object of my invention is to so construct the apparatus that it may be used for combined scalp treatment and muscular development, or for muscular development alone.
Further objects of the present improvement will appear from the following description:
In the accompanying drawing Figure 1 is a perspective view of my improved apparatus, showing it used for combined scalp treatment and muscular development.
Fig. 2 is a side elevation of my improved apparatus, showing it arranged'to be used merely for muscular development. 1
F g. 3 is an enlarged central longitudinal sectional view of Fig. 1, showing the cylinder connecting the pipepartly in elevation.
- are usedforregulating the strength or pull required in operatingthe pistons.
F1g. 6 is an elevation ofvthe outer end of the valve, shown in Fig. 5 with its pointer and dial.
In carrying out my present improvement, I use two cylinders 1 and 2, which have inner closed ends 3 and 4, and these closed ends 3 and 4 are connected by a centrally arranged housing 5. The outer faces of the cylinders and the inner sides of the ends of the housing 5 are provided with meshing screw-threads 6, whereby the cylinders are attached to the housing 5, through the medium of said screw-threads. This arrange ment serves to firmly connect the cylinders and the housing, whereby they become a unitary structure. The lower side of the housing5', is provided with a depending internally screw-threaded nipple 7 into which a suitable tube 8 is screw-threaded as at 9. This tube 8 has its inner end open and communicating with the housing 5, while its outer end 10 carries a perforated supporting plate 11, adapted to rest upon the head of'the user. The inner end 10 of the tube 8 is open and in communication with a suitably shaped helmet 12, the helmet carrying at its lower end a rubber diaphragm 13, for tightly fitting the head of the user.
A nipple 14 is rigidly attached to the outside center of the helmet, 10 and the housing nipple 7 and helmet nipple 14 are united by suitable screw-threads15.= By this arrangement the helmet and tube 8 can both be disconnected from the housing 5 for a purpose hereinafter explained. Within each of the cylinders 1 and 2 are leather faced pistons 16, and piston rods 17 have their inner ends 18, suitably connected with the pistons 16, and project to the outside of the cylinders through suitable stuffing boxes 19, carried by the detachable outer heads 20 of the.
cylinders. The outer ends of the piston rods 17 V are shaped into suitable handles 21,
' to be grasped by the hands of the user for and connected therewith by suitable screW-, threads 26, the inner end of the casing ex tendingthrough the wall of the cylinder and receiving a clamping nut 27, there being a suitable packing washer 28, between the nut 22 and the cylinder wall 1' to make an air-tight joint. This valve casing 24 has its inner end provided with a suitable valve seat 29 to'receive a valve 30, which has a leather face 31. through the casing and the valve stem passage has its inner portion enlarged, as at 33, to receive a suit-able spiral spring A washer is located on the inner end of the valve stem 32 and held thereto by a suitable pin 36. By this construction the valve30 is normally held to its seat by its 7 spring 34.
The valves that are located in the ends 23 of the pipes 22 and 22 are of the same construction, so that the description of only one of these valves is necessary.
The inner heads 3 and 4 of the cylinders 1 and 2'are each provided with transverse openings 37, that are controlled by spring held valves 38. These valvesfare hel'dno'rmally to their seats for closing the openings 37 by suitable springs .39.
The outer and inner ends of each cylinder 1 and 2 are provided with adjustable outlet valves A, and the construction and object of which will now be described. All of these valves are of the same construction. In describing the details of these valves, reference is made to Fig. 5'. These valves have a casing 40. The casing extends into its cylinder 'and the outer end 41 of the casing is reduced and projects outwardthrough the wall of its cylinder 1, and receives a screw-threaded nut 42. A suitable packing 43 is located between the shoulder 44 of the casing and the inner surface of the cylinder wall 1, whereby an air-tight joint is made between the casing and the cylinder wall. This casing is provided wlth a centrally arran ed lon itudinall extendin o enin 54 b b D b the outer end of which has'asuitable valve seat 46. This valve casing 40 is angular in The valve stem 32 passes.
valve stem 50 extending through the longitudinal opening of the case and is provided with external screw-threads 51. An adjust- V able nut 52 meshes with the screw-threads of the valve stem and is angular in outlinev to correspond with the angular shape of the opening 47. The outer face of the nut 42 is provided with a notched dial 53 and the valve 48 is provided with a pointer 54. A I
suitable spiral spring 55 islocated between the adjustable nut 52 and the bottom of the enlarged opening 47.
In operation, when the pistons are moved either in or out, the strength'of pull re-' quired is determined by the force required to force the air from the cylinders through the valves A; This is regulatable by turn ing the pointer 54, which turns the valve and its stem and will either loosen or tighten the spring 55 and thereby regulate the amount of air-pressure requiredto lift the valve from its seat and permit air to escape pounds. By this arrangement the usercanregulate the power or strength requiredto move the pistons in their cylinders and this can be regulated to require more or less'pull for pushing the pistons than for pulling them out, and vice versa. the user in beginning with the apparatus for physical development will set. the pointers at the places on the dial adapted to his physical strength. In the use of this appa- Furthermore,
ratus from day to day, theuser can advance the. pointers notch at a time to keep. pace with his physical development'from the use of the apparatus, and at the same time; will be able to observe the progress of his physical development ,and to determine his strength when desired in operating the pis tons inrtheir cylindersg Y r is.
When the apparatus is used solely for physical development, the helmet and tube 8 will be removed'from the housing nipple V 7, and a valve similar to the valves A will be screwed into the nipple 7.. By this ar-- rangement the suction actions of the pistons can .be regulated in the same manner as the air escaping pressure is regulated 'by-the' valves A. r a
With the helmet attached as. shown in Figs. 1 and 3,.when the pistons aremoved outward, asuction within the helmet is caused through'the valve controlledopenings 37, and when thepistons are. moved inward, asuction is caused :within the helmet through the valves 30, at the endsof the pipes 22 and 22'. Also when the pistons are moved outward, the valves 30 are closed, so that air can escape from the outer end of the cylinder only through its adjustable valve A. Likewise, when the pistons are moved inward, the valves 38 are closed so that air can escape from the innerv ends only through the adjustable valves A, at that end of the cylinder.
When an adjustable valve, like the adjustable valves A is used, in the place of the helmet, it will be attached in reversed position, as shown at A, Fig. 2, and is capable of regulation through the medium of the nut which is adjustable on itsstem, as de scribed in connection with the adjustable valves A.
In this way my apparatus is capable of the conjoint action of scalp treatment and physical or muscular development of the user, or may be used solely as an exercising device for muscular development of the user.
